diamond tools in China business development on Reflections

An industry, the industry's overall level of development ultimately depend on the level and growth of business. Of the diamond tool industry in order to achieve success from large to strong changes, the need for enterprise independent self-reliance, self-improvement, which will promote the  GUSHI concrete polishing pads development of the industry.
1. Clear corporate strategic positioning, enterprise synergies and improve the overall competitiveness of
Over the years, the domestic diamond tool business has experienced raw material prices, the export tax rebate rate, the RMB against the US dollar continues to appreciate, the world economy is slowing down, the domestic floods, earthquakes and other natural disasters and other adverse factors, to bring greater business all enterprises pressure.
How to enhance the competitiveness of enterprises to deal with complex business situation. First, enterprises should clear strategic positioning, according to their own reality, to develop viable development strategy, give full play to their strengths, to make their own fist specialty products. Avoid homogeneity, low-end, low-cost vicious competition. Secondly, we must play to the enterprise cluster synergies and improve the entire industry a competitive advantage, we must attach great importance to and give full play to the role of associations, give full play to association information platform, industry management and guidance, and guide enterprises in the industry gradually embarked orderly competition and healthy development track.
Around the tool industry, broaden and extend its product line, improve the product line; always adhere to the technical and management innovation; focus on the brand, sales channels and cultivate corporate  GUSHI concrete diamond blades culture construction, adhere to the balanced development of domestic and international marketing strategy , committed to continuing to build a business, fast growth and healthy development of international famous enterprises.
2. Strengthening scientific research and technology investment, improve the capability of independent innovation
Strengthen the independent innovation capacity to promote fundamental to long-term development, particularly in the context of economic globalization, growing international competition, lack of independent innovation ability will affect our survival and development of the diamond tool industry. At present China has built several national technical center, but so far, the diamond tool products companies in only a few provincial corporate research centers, and has more than 1,000 manufacturing enterprises, the annual income of nearly billion industry level is not commensurate. Therefore, China should realize the diamond tool industry from large to strong changes, you  GUSHI tct circular saw blades must also carry out all the work of independent innovation.
In recent years, some enterprises in independent innovation capacity-building to do some work in the technological development has also made some breakthroughs, but, objectively, in terms of research investment also studied the depth, product level, personnel structure, all there is a large shortage. Currently, companies are further increase investment in scientific research and technology, has "Enterprise Technology Center Project" included in the listing and financing projects to improve technology center hardware facilities, the construction set diamond tools, metal tools, power tools into one comprehensive state-level enterprise technical center.

Diamond tools for a wide variety

Diamond cutter high hardness, long life, has been widely used in various manufacturing industries, the following is a brief look at the diamond tool manufacturing materials
High hardness and wear resistance of diamond cutting edge is very sharp, the blade roughness value is small, low friction GUSHI carbide tipped saw blade  coefficient, good anti-adhesion, high thermal conductivity, easy to stick the knife when cutting and BUE, machined surfaces good quality. In the processing of non-ferrous metals, energy efficient processing of non-ferrous metals and non-metallic materials, such as copper, aluminum and other nonferrous metals and alloys, ceramics, un-sintered carbide, various fibers and particulate reinforced composites, plastics , rubber, graphite, glass and a variety of wear-resistant timber (especially solid wood and plywood, MDF and other composite materials). 1, variety, product series: domestic diamond products presented species diversity, product refinement, application specialization trend. General scale enterprises have dozens of product specifications, slightly-scale enterprises have hundreds of product specifications, larger enterprises  GUSHI sanding discs with thousands of product specifications and the products can be customized according to user requirements. 2, the product according to user requirements are divided into two classes: the use of diamond tools, habits and cost factors have been artificially divided into two distinct series: First, a larger amount, the price is relatively low DIY products, such products have a greater market; Second, the main high-end professional products for the international market. Due to recent rapid increase in Chinese production and quality diamond, diamond products to the continuous improvement of production technology, high  GUSHI carbide drill bits levels of manufacturing diamond tools products has made significant progress, and the price advantage is obvious, professional products in the international market competitiveness has enhanced.

broad areas of diamond cutting tools applications

Diamond Tool is mainly used for a variety of non-ferrous metals such as turning aluminum, copper, magnesium and its alloys , tungsten carbide and wear a strong fiber-reinforced plastic materials, metal matrix composites, wood and other non-metallic materials . When machining cutting speed , feed rate and depth of cut depends on the processing conditions and the  GUSHI masonry drill bits hardness of the workpiece material . Synthetic polycrystalline diamond compact (PDC) and application performance close to PCD tools , mainly used in non-ferrous metals , tungsten carbide , ceramics, non-metallic materials ( plastic , hard rubber , carbon rods , wood, cement products, etc. ) , composite materials such as cutting, gradual replacement carbide cutting tools . Because the diamond particles bonded to ask some residual metal and graphite , wherein the bonding metal to form coalesced or vein -like  GUSHI diamond discs distribution state will reduce tool life and wear resistance .
Besides the presence of residues of solvent metal , solvent metal in direct contact with the diamond surface . Lower (PDC) antioxidant capacity and tool heat temperature , so cutting tool is not stable enough . Diamond Thick Film Cutters preparation process is complex, because between the diamond and the low melting point metals and their alloys with high interfacial energy . Diamond generally difficult to be wetted by the low melting point  GUSHI diamond bandsaw blades solder alloy . Weldability is poor, difficult to produce complex geometry tools, welding tools TDF therefore can not be applied at high speed milling . Diamond- coated tools can be applied to high-speed machining , because in addition to diamond coated tools have excellent mechanical properties, diamond coating process capable of producing any complex shape cutters for high speed machining materials such as aluminum, titanium and difficult to process non- aeronautical metallic materials such as graphite electrodes.

The new technology of diamond cutting tools

High-speed cutting tool holder system processing center, CNC machine tools had previously been using the traditional taper tool system, which taper shank due to the combination alone, the lower shank and spindle  GUSHI diamond hole saw coupling rigidity, spindle speed exceeds 10000r/min, less rigid coupling is more apparent. ATC ATC handle on using it after each tool change, tool radial dimensions are subject to change, there is a problem of repeat positioning accuracy is low. To solve these problems mainly improved standard 7:24 holder. Inspired by the HSK, in recent years there has been a new connection technology 7:24 handle, such as Japan's Showa research companies and large companies were developed three contacts (3LOCKSYSTEM) and duplex (BIGPLUS) 2 species GUSHI sanding discs  and 7: 24 joins the handle. 7:24 compared to the standard holder, which is coupled with a higher rigidity and precision can be used for fast, efficient cutting, and also compatible with existing or machine 7:24 handle, the handle is next 7:24 development, in addition to the standard 7:24 handle structural transformation, the main use of new HSK shank and KM shank. Shank is a new high speed taper shank, and its interface with cone and face 2 face  GUSHI abrasive flap wheels while positioning the way the handle is fixed, cone length is shorter, is conducive to ATC and the speed of light , the use of face orientation, completely eliminating the axial positioning errors, high speed, high precision possible is our domestic manufacturing tool manufacturing development. Tool and spindle speed connection technology with advances in technology in the future will be continuously developed

Concerned about the long-term development of diamond cutting tools

The diamond tool industry worldwide transfer completed, the domestic industry concentration is low. Currently, China, South Korea has GUSHI ceramic tile saw  become the world's diamond tools production base, American and European countries also retain a small amount of high-end capacity. In the United States, imports of Chinese products accounted for 40% -50%, count about 70% -80% in Korea. As the barriers to entry are not high diamond tools, domestic concentration is low. In a large number of small production base of stone tools and processing enterprises, often only a few types of products, profitability compared with the large-scale enterprises (such as Bo deep tools) there is a GUSHI turbo diamond blade  big gap, along with upgrades and diamond tools category The gross profit margin of return, industry consolidation trend.
Alternative Space huge diamond tools: diamond tools is an emerging industry, there is still much room for its alternative to traditional tools. Still using traditional soft abrasive. If fully realized alternative, ceramic production consumed diamond tools production value will double. The  GUSHI carbide saw blades past two years, beginning diamond tools used for wall, floor grinding, more mature foreign and domestic start-ups. Overall, with the continuous improvement of existing areas of penetration, as well as new applications and open up a huge room for growth in the market size of diamond tools.

Diamond tools maintenance tips

First, as we explain that the performance characteristics of the diamond

tool : diamond tool is mainly used for grinding tools and abrasives ,

diamond pen made ​​for some wheel dressing , only a small diamond welding or

mechanical clamping method fixed on Arbor ground GUSHI turbo diamond blade  into the desired angle as

the cutting tool . Second , the diamond tool has high hardness and wear

resistance ( abrasion resistance of natural diamond carbide is 80-120

times , 60-80 times of the synthetic diamond ) . Its hardness of cemented

carbide hardness higher than several times , so it has good machinability

and tool life . In the processing of plastics , diamond tools durability

hundreds of times higher than the carbide . Add to fly : to achieve an

accuracy guarantee . Processing material hardness is higher, this

superiority is also more prominent. These characteristics of the diamond

tools are just some of the summary of our knowledge , we hope to give

valuable advice variety of products , so that our products can continue to

improve with a new one , for which express our GUSHI stone polishing pads  heartfelt thanks ! In the

industrial production of diamond tools use is essential, as a routine use

in high frequency diamond tools not only the price is relatively high, but

once the damage will affect the post- production , so today , we want to

explain about the diamond tool maintenance: 1. single point diamond

dressing tool head can not be vertically aligned with the center wheel ,

which normally takes tilt 10-15 °. 2, in the  GUSHI abrasive grinding wheels first place the diamond tool

to clamp seat , be careful not to hit the wheel surface . 3 , the heat can

not be dresser " quenching " , in the dry dressing must remain trimmed two

intervals , sufficient to heat the dressing tool coolant .
4, can not assume that the ideal flat surface with a grinding wheel . At

the beginning of dressing , find the highest point of the wheel , for

trimming. 5, if possible, the addition amount of each repair wheel on the

wheel radius can not exceed 0,001 inches. In addition to an excessive

amount of repair can cause premature wear of the diamond dressing tool

head and frequently broken.

diamond blade saws easily collapse or broken tooth problems

Questions about the high-speed hacksaw teeth or broken easily collapse
When using high-speed hacksaw to cut various types of pipes, there are many situations because it is not caused by the attention to detail.
(1) Material: Sometimes the problem is with the material being cut. Some suppliers of production materials market, the GUSHI cutting discs  process of cutting corners, causing the material to be cut contains too many impurities, so that when the blade hit the impurity particles, hard blade may break or give great sound, cut out of the surface uneven. But with softer high-speed hacksaw will not break, but the results will be skewed cutting phenomenon, because there will be a shift phenomenon blade in contact with the particles. The hardness of the material itself or some may not be too high, but the elements are added during the production process used and the cutting tool may cause problems or result in blunt edge chipping.
(2) Blade: Blade not properly gracefully compressive deformation, serrated blunt did not wear out, yaw poor, poor choice of teeth, serrated grinding bad. In short, poor quality blade.
(3) cutting machine: the state of the fixture, the blade is not installed correctly, the blade speed is not correct, not suitable feed rate, cutting oil selection, and the saw blade and cutting machine errors will be affected by each other. Skew the results of a customer complained that cutting through our observations to the scene, feeding racks are not fixed, when workers transport materials, often crooked off accidentally collide. Work Material crooked off after feeding rack, of course cut out of the material must be crooked. Customers also complained frequently broken saw blade can not  GUSHI sds hammer drill bits be solved, we got to the scene found the mechanical design of the book has been pointed out, the longer the cutting material, there must be a fixed station to make the cut section was not shaking. However, when the customer is still chopped materials and the same, so the blade will have to be cut by shaking timber crashed. Customers also have the machines installed at the time and did not make the level of correction, so the machine is fundamentally crooked.
(4) the use of counterfeit machine: using poor quality metal circular sawing machine, the price was very cheap but in the production process of steel is not enough to cause the cutting vibration, so that there is a gap down the blade, cutting blade will have shaken will ultimately affect the properties of the cutting blade.
(5) manual machine operator: When using a manual machine, the user experience is more important, the user can feel the sharpness of the blade into the blade when the intensity and relatively easy to determine whether you can then use the saw blade ! The pneumatic or hydraulic models require the  GUSHI diamond polishing tools user to more cautious use of the saw blade, cutting the workpiece which can not be blind to experience cutting grounds. Because each piece of the blade when cutting a workpiece not be the same, so that also in the life of a generally sawtooth a range. At the beginning of the cutting and stopping cutting, do not feed too fast, it may cause broken teeth and damaged. When the case has emerged relatively blunt serrated continued use will be pulling teeth, broken teeth and so on, there will be a serious crack blade body, the phenomenon of explosive film!

What is the working principle of diamond cutting tools

Workpiece rotation, straight or curved diamond tools for cutting moves in the plane. General lathe turning, turning round to internal and external cylindrical workpiece, face, conical surface, forming surface and thread and so on. Turning external cylindrical surface, turning along the axis of rotation is parallel to the direction of movement of the workpiece. Turning on or off the end face of the workpiece perpendicular to the turning direction of the horizontal axis of rotation of the workpiece movement. If the turning trajectory of the rotation axis of the workpiece at an oblique angle, the conical surface can be processed. Turning shaped revolving body surface, can be shaped tool tip trajectory method or methods. When turning, the workpiece is rotated by a spindle primary movement; holder for turning the turret feed movement. Cutting speed v is the linear velocity of the workpiece surface at the point of contact with the tools rotating (m / min); cutting depth of each cutting stroke of the workpiece is to be machined and the machined surface of the vertical distance (mm) between the surfaces, but in the compared with vertical contact length in the feed direction of the workpiece when turning and turning off and forming (mm). Feed each piece represents a turn when turning the feed direction of the displacement (mm / rev), can also be turning feed per minute (mm / min), said. High-speed steel tool used for turning ordinary steel, cutting speed is generally 25 to 60 m / min, carbide diamond tools up to 80 to 200 m / min; using coated carbide turning up at the highest cutting speed 300 m / min.
    Turning it normally roughing and finishing (including semi-refined car) categories. Rough sought without reducing GUSHI concrete saws  the cutting speed conditions, using a large depth of cut and a large amount of feed to improve the efficiency of turning, but only up to precision IT11, the surface roughness of Rα20 ~ 10 microns; semi-finishing and finishing maximize the use of high-speed and a smaller amount of feed and depth of cut, precision up IT10 ~ 7, the surface roughness of Rα10 ~ 0.16 microns. In the high-precision lathe with a fine grind of diamond tools repair speed finishing non-ferrous metal parts, precision can reach IT7 ~ 5, the surface roughness of Rα0.04 ~ 0.01 microns, which is called the turning mirror turning. If the cultivation or 0.1 to 0.2 microns concave convex on the diamond cutting edge tools, the  GUSHI masonry drill bits surface unevenness is generated for turning the rows of micro-electrode stripes, damask luster present in the diffraction effect of light, can be As a decorative surface, which is called Rainbow turning face turning. When turning, if the rotation of the workpiece, while also turning speed ratio corresponding (tool speed is generally several times the speed of the workpiece) and the workpiece rotating in the same direction, can change the tools and the workpiece relative to the trajectory, producing the polygonal cross-section (triangular, square, hexagonal prism, and the like) of the workpiece. If the diamond tools vertical feed, while each turn relative to the workpiece, tool GUSHI sanding discs  holder attached to a periodic radial reciprocating cam surface finish can or other non-circular cross-section. In Relieving lathe, similar works can be processed in some multi-tooth cutter (such as shaping cutters, gear hobs) flank teeth, called shovel back.

Some matters tile saw blades should be noted

Industrial profiles blade Precautions
1 Keep alloy saw hanging vertically on the drying rack , be sure to avoid damp places , do not alloy blade flat on the floor or  GUSHI diamond polishing tools shelf, flat lead alloy blade deformation.
2 When using , do not exceed the specified maximum speed. Speed ​​calculations attached. 3 When used, must be with shields, gloves , helmets, safety shoes , safety glasses . 4 When installing alloy saw blade, you must first confirm the performance of the saw table , uses, it is best to GUSHI core bits for concrete  read the manual saw table . Avoid loading the wrong , causing an accident.
5 When installing alloy blade , alloy blades must first check whether there is a split , distort , fill level , after the fall of teeth and other phenomena, then install it. 6 super-hard alloy saw sharp serrated prohibit collision , falling to the ground, must be gently .
7 After loading alloy blade , you must confirm the center hole of the blade is firmly fixed on the saw table flange , gasket must be good washer ; then gently push the hand saw blade confirmation piece rotation is eccentric shaking.
8 alloy blade must cut direction indicated by the  GUSHI abrasive grinding wheels arrow is aligned with the direction of rotation of the saw table . Do not install the opposite direction , installed the wrong direction can cause tooth out .
9 preroll time: After replacing the alloy saw blade, before use pre- turn for a minute , let the saw table to enter the work state , to be cut.

Single Crystal Diamond tools of design principles

Single crystal diamond tool design principles and the use of technology are mainly the following points.
1 single crystal mirror processing mechanism tool
    Residual area after cutting height h = f / (ctgkr + ctgkr ') is machined surface roughness value theory, it varies with the feed rate f, the main tool and vice declination angle kr kr' is reduced and the concrete saws  reduced. As the main angle kr Fy force will decrease rapidly increased vibration caused by knives, reduce the feed rate f will affect the cutting efficiency, it is generally by reducing the deputy angle kr 'to reduce the surface roughness.
    Conventional cutting tool surface is rough, poor edge formation, if the angle is too small selection of the sub, one secondary cutting edge is not mapped to complex formation would have been processed on the surface; also exacerbate other and have flanks machined surface friction, the machined surface "nap." Therefore, in conventional cutting, machining deputy angle of about 2 ° surface roughness value of the minimum, further reducing the deputy angle will make the deterioration of the surface quality of the machined.
    Surface roughness can be smaller than a single crystal diamond tool Ra0.01? M, edge quality can be achieved at least 100 times under a microscope to observe a defect, the coefficient of friction combined with minimal, so the relief angle can be reduced to the limit of 0 ~ 2 ', thereby allowing the dry core drill bits  surface roughness is equal to zero or close to the theoretical value, the actual value of the surface roughness of the mirror can reach or exceed the requirements of a smooth surface.
    Thus, the tool itself, the mechanism of single crystal mirror processing tool is through ultra-smooth surface of the tool and defect secondary cutting edge (wiper) the role of the surface roughness to the theoretical value is close to zero processing mirror-processing results.
Single crystal diamond tool design
    Design Tool monocrystalline main factors to consider when you are: ① be required precision machined parts; ② actual processing conditions; characteristics ③ diamond material.
    Design monocrystalline tool, you should follow the drum wheels  following principles: ① As the single crystal diamond high hardness, processing difficulties, so the shape of the tool should be as simple as possible; ② based on single-crystal diamond brittleness, poor impact resistance characteristics, should be combined with the actual processing conditions by optimizing the shape of the tool geometry, improve head impact resistance; ③ is designed according to the length of the wiper blade precision machined parts, taking into account the ability of the tool cutting thin

diamond cutting tools and wear what reasons

Diamond cutter high hardness, long life, has been widely used in various manufacturing industries, the following is a brief look at the diamond tool manufacturing materials
High hardness and wear resistance of diamond cutting edge is very sharp, the blade roughness value is small, low friction  GUSHI metal grinding wheel coefficient, good anti-adhesion, high thermal conductivity, easy to stick the knife when cutting and BUE, machined surfaces good quality. In the processing of non-ferrous metals, energy efficient processing of non-ferrous metals and non-metallic materials, such as copper, aluminum and other nonferrous metals and alloys, ceramics, un-sintered carbide, various fibers and particulate reinforced composites, plastics , rubber, graphite, glass and a variety of wear-resistant timber (especially solid wood and plywood, MDF and other composite materials). Diamond Tool harder the material, the better the wear resistance, the higher the hardness, the lower the impact toughness, the GUSHI sanding disc for drill  more brittle materials. Tool hard to postpone the use of time as the tool will have some wear and tear, the impact of tool wear reasons, what does? Following a brief temperature difference
Effect of temperature on the blade process mainly manifested in two aspects: First, cause agglomeration of diamond graphite; second is caused by hot carcass Ili diamond and diamond particles resulting from premature loss.
Mill damaged form are the following: abrasive wear, local crushing, crushing a large area, off, binders direction along the cutting speed mechanical abrasion.
By alternating thermal stresses, and also to GUSHI diamond polishing tools  withstand the stress of alternating cutting, fatigue cracks occur locally broken, revealing new sharp edges, is an ideal form of wear; large broken: diamond particles in the Leads when subjected to impact loading, the more prominent grains and grain prematurely consumed; cause early termination tool usage time.

Application and the status of Diamond tools

 As the world economic development, improving people's living standards, natural stone (granite, marble), jade, advanced artificial stone (ceramic stone), ceramic, glass, and cement products, has been widely used in homes, buildings decoration objects, used in the production of a variety of decorations, household items and applications in road, bridge construction. On the processing of these materials, we need a variety of diamond tools.
   Last 10 next year, Chinese production  GUSHI concrete diamond blades of diamond tools business has developed rapidly. Judging from the number of enterprises, production of diamond tools business nearly a thousand, annual sales income of more than ten billion. Jiang Zhongguo production of diamond tools business as much as a large scale, is any other country in the world can not be compared, will become the world's diamond tools supply base. Some varieties of Chinese diamond tools also has a high level of quality, a number of brand-name foreign diamond tools also commissioned the production of Chinese enterprises. However, most of the production of most of the products are of substandard quality, low price products. Although many number of Chinese exports diamond tools, most of them low-priced products, known as 'junk'. Even high-quality products, which meet or exceed the quality of similar foreign products, because it is made in China, but also can not afford to sell at good prices, seriously affect China's image. What is the reason for this situation is? To sum up two main reasons. First, the low level of technology. Development of diamond tools production technology has been divided into three stages. The first stage is used for elemental powders by mechanical mixing matrix plus diamond diamond tool production process. This process is prone to segregation of components; sintering temperature is high, likely to cause graphitization of the diamond, the diamond of lower intensity. Due to a combination of various matrix materials are mechanical, not fully alloyed diamond matrix package inserts for poor, difficult to produce high-end products. The second stage is the use  GUSHI cutting discs of pre-alloy powder for mixing matrix plus diamond diamond tool production process. This process is due to be fully alloyed matrix material, the sintering temperature is low, the diamond will not reduce the strength of the ingredients to avoid segregation of the diamond package inserts produce good results, the diamond features play very well. For carcass production with pre-alloy powder diamond tools, high-efficient, slow decay characteristics that can produce high quality diamond tools. The third stage is the use of pre-alloy powder as matrix, using diamond ordered (multi-layer, uniform diamond) technology. This technology is the technical advantage to accommodate pre-alloy powder, in turn ordered diamond, the diamond had to make full use of each piece, mechanical mixing process overcomes the uneven distribution of the diamond to bring serious defects affecting the cutting performance , is the world's production of diamond tools, the latest technology. In commonly used? 350mm diamond cutting discs, for example, the cutting efficiency of the first stage of the technical 2.0m (100%), the second stage of the technical cutting efficiency is 3.6m (up to 180%), the third phase cutting efficiency technologies 5.5m (up to 275%) or more. The first phase of the technology in China currently produces diamond tools in the enterprise, 90% still use less than 10% of companies use the second phase of the technology, the use of individual third stage technology companies. Is not difficult to see that the current Chinese enterprises in the production of diamond tools, a few companies are fully capable of producing quality products. However, the vast majority of companies still use the traditional, outdated technology.
Second, vicious competition. Diamond tools are consumables market demand. According to the current technology of the GUSHI dry core drill bits  first stage production of diamond tools, diamond tools on new business easier. In not too long a time, the Chinese production of diamond tools business reached nearly a thousand. ? To commonly used 105mm diamond saw, for example, the product level is the 'quality' of prices above $ 18, about 10%; product grade is 'standard', the ex-factory price of about 12 yuan, accounting for 50% ; product grade 'economy', the ex-factory price of around 8 yuan, accounting for about 40%. These three products is calculated according to the average social cost, 'high-quality' margin products can reach more than 30% profit margin 'standard' products can reach 5 to 10%, 'economy' products can only be guaranteed as well, most Enterprise prices are below $ 8, and even as low as 4 yuan.

Some of the major role of Core Drill Bits

First, what is the drill
Is used to drill a workpiece to drilling tools.
Drill generally just (W18Cr4V or W9Cr4V2) made ​​of high-speed, divided twist , flat drill, center drill , countersink hole drilling, deep hole drilling , which is our twist fitter , machining the most  GUSHI metal grinding wheel common drill .
This is a paper I have to talk about is the main method of twist drill sharpening its restructuring . I began to talk about from the twist , first introduces the basic knowledge under twist .
Twist the type and structure:
Straight shank twist drill into , Morse taper shank . Generally straight shank twist drill diameter 13mm or less in diameter Morse taper shank twist drills are in 13mm or more. Typically the twist handle , neck , working part , wherein the working portion and the guide portion , the cutting part . Specifically as shown in Figure
( A ) the handle - is generally used to transfer the clamping force and a smaller diameter than Φ13 mm straight shank drill made ​​it , no clear straight shank drill neck , the diameter of the drill , trademark etc. engraved on the handle directly . Φ13 mm and a diameter greater than generally made taper shank drills , taper shank drills taper is produced according to national standards , according to the size of the drill diameter and made Mohs 1 #, 2 #, 3 #, 4 #, 5 #, etc. taper, the larger the size of the handle numeral greater . Flat tail taper the ends for easy removal and  GUSHI diamond bandsaw blades transfer torque from the drill bit role.
( 2 ) Neck - The neck is connected to the handle portion and a portion of the work , but also for the grinding wheel retraction drill is used , the diameter of the drill itself , materials and trademarks are engraved on the neck.
( 3 ) working part - it is divided into two parts ① cutting guide and the guide portion twist to the right direction to keep working , and when re- sharpening drill bits , cutting guide portion and gradually become part and to work. The guide portion has two parallel helical grooves , is to be formed to accommodate the cutting edge and the removal of the GUSHI turbo diamond blade  chips and facilitate the input of the cutting fluid . There are two edges with a guide portion , its diameter is slightly inverted cone , every 100mm length , shank diameter is reduced to 0.05-0.10mm, both to guide the direction of the drill bit cutting , but also can reduce the drill hole wall friction . ② a key part of the cutting portion of the drill bit , the flank twist of six , five blade consists of: a rake face comprising two , two rear flank , two sub behind the two main cutting edges , two auxiliary cutting edge , a horizontal edge , namely " a sharp three blade ." As shown in Figure
Through these two points , I believe we have fully understood the basics of the drill point , so I can deeper introduce myself sharpening methods and steps up .
Twist mainly by cutting part of the cutting , but we have to start from the drill bit is also part of the transformation . Start sharpening my own way to start talking .

Characteristics of diamond tools and applications

1, using a diamond low coefficient of friction, and non-ferrous metal

affinity characteristics of small diamond-hard metal cutting tools, saw

blades can be processed copper, aluminum, iron, etc., but do not stick

a knife, diamond tools and cutting tools can  GUSHI diamond hole saw effectively prevent the

occurrence of metal bonding .
2, used for processing high hardness nonmetallic materials, such as

glass fiber reinforced plastic, filled silicone materials and other new

materials.
3, diamond tools, saw blades easy passivation, cutting small

deformation, high surface quality can be obtained.
Diamond tools for our manufacturing industry with a lot of efficiency

and convenience, then I do not know the performance characteristics of

the diamond tool know how much?
Diamond tool is mainly used for grinding and abrasive, diamond pen made

for some wheel dressing, only a small diamond welding or mechanical

clamping method of fixing the shank, ground into the desired angle as

the cutting tool.
Diamond tools have high hardness and wear resistance. Its hardness of

cemented carbide hardness higher  GUSHI concrete diamond blades than several times, so it has good

machinability and tool life. In the processing of plastics, diamond

tools durability hundreds of times higher than the carbide.
Diamond tools have high wear resistance (natural diamond 80-120 times

the wear resistance of carbide, synthetic diamond is 60-80 times), plus

fly: to achieve an accuracy guarantee. Processing material hardness is

higher, this superiority is also more prominent. PKD tool high

processing costs, its rough prices are expensive compared to using the

tool cutting PKD consuming and laborious, and the rejection rate is

quite high. Apart from the geometry GUSHI masonry drill bits  and dimensions of a manufacturing

error, but due to the brittle material PKD high, prone to chipping on

the cutting edge gap, which is difficult to describe the precision tool

manufacturers for production and processing of PKD tool when done. PKD

tool in the development process, and now there may be more economical,

more quality PKD tool to ensure that such production and processing,

the spark is a good method of processing PKD cutting tool.

How to make a diamond grinding wheel wear slower reasons

Diamond Wheel in our daily lives has become so widespread, that how can you wear diamond wheel is often slow, you know? If you do not know to give with Xiaobian look at it.
Select the diamond grinding wheel hardness general principle is: the processing of soft metal, in order not to make premature loss of abrasive, then use a hard wheel. Wear resistance and long life. Diamond grinding wheel ratio up to 3500-5500, a hundred times higher than normal corundum grinding wheel, 3-5 times higher than ordinary diamond wheel. When  GUSHI diamond polishing tools processing hard metal, in order to make timely blunt grit off, thereby exposing new abrasive grains with sharp edges (ie, self-sharpening), use a soft wheel. Or because the soft material in the grinding wheel abrasive wear is slow work, without departing too early; latter is because the grinding of hard materials, abrasive wear of the grinding wheel work faster, require faster updated. High efficiency, good overall economic efficiency. Grinding sharp, small grinding force, diamond grinding wheel dressing cycle length, less the amount of dressing, long replacement time; long life cycle, grinding ratio, getting a better economy, use good shape retention, without regular Replace the wheel and wheel dressing, saving time and improving working conditions conducive to machining operations. In the grinding force and grinding conditions are low speed after using diamond grinding wheel, and its distribution on the surface of a large number of angular, consistent diamond abrasive wear reflective facets. This is GUSHI circular blades  mechanical wear due to mechanical friction and superhard abrasive diamond material produced. This wear is gradual, with the amount of wear of the abrasive grinding stroke length proportional relationship.
At higher temperatures the grinding conditions grinding zone, diamond grit diamond wheel on and graphite oxidation and loss. According to the nature of the diamond understood, oxidation, depending on the degree of graphitization of the diamond abrasive crystals integrity, and the degree of graphitization and also on the crystal orientation. Good crystal perfection diamond abrasive, oxidation, low degree of graphitization loss.
On the part of diamond grit diamond wheel surface localized fracture and fragmentation, resulting in whole shedding. Cleavage  GUSHI stone drill bits occurs diamond abrasive damage. Since the crystal cleavage plane of rupture was determined by the crystal structure of factor 7 bond type, intensity and distribution of the generated, which is often generated along the surface of the orientation strength of the final bond. Random distribution of grains to determine their cleavage occurred damage is inevitable.

Alloy circular saw blades that content quality inspection

Core Tip:. ① substrate surface finish inspection, application plug blade hole detection, or the naked eye holes over the surface of the knife if there is full contact with the blade edge ruler detect flatness or wavy and pot-shaped, with the end
①. Matrix test surface finish, blade hole  GUSHI colde saw blade plug detection application, or the naked eye hole cutter with completely over the contact surface with the knife blade flatness ruler detection or wavy and pot-shaped, with a client-side jump jump cytometry tooth holder has an oxide or glitches with durometer hardness uniformity detection surface rust and other indicators.
②. Weld inspection wire fluidity, weld strength, welding burns oxide should not be beyond the undercut, solder alloy tooth deflection degrees, depending on the angle between the bottom and the minimum width of the alloy matrix should not be less than 1.2mm, it has cracks, oppose any Alloy Welding pressure detection firmness.
③. Grinding teeth grinding detection plane A, B two tables side by checking with moderate (by surface contact pin) suitable level contacts, detect lateral angle, side front corner by applicable Point
Touch table shows how much depends on the thickness of the alloy with a dial gauge to check, only check the tooth GUSHI tile cutting blades  thickness, but the majority of the blade itself or wavy pot type parameter must have a bad end is always the best way to jump meter is the most accurate test, Also check the tooth surface finish, such as wheel apparent traces of some poor durability of the knife can not see the two flanks, accurate detection angle was still true after grinding. After checking the angle, in radians or allowed to produce clear signs of the wheel or the back rake angle, when the two sides of trails around the tooth jump in line, do not allow left or right high right low left high low, generally detected with a diameter hop, visual inspection main cutting edge in front of the human body is not allowed to  GUSHI carbide saw blades see any white lines, when Lee Tudor feel with obvious edge detected with visual clarity. Blade rake angle or rake smooth wheel Keys, no two blades, domestic mill still hand front corner motive or mechanical automata, often grinding rake angle wheel or front edge retraction pressure, causing the blade to produce an obtuse main cause The main reason the tool is not durable, Germany retract hydraulic lift with grinding function, so the product is very duo Lee grinding.

Alloy Saw What Precautions

One must carefully read the items mentioned in the manual cutting machines and packaging shell on the front. 2, according to the material being cut blade varieties to select and check the blade for cracks, distortion, lost teeth, do not use if damaged blade. 3, be sure GUSHI turbo diamond blade  to install the cutter blade guard when using the shell, and wear masks or protective eye. 4, please check before installing blade cutter spindle is beating, when you install the blade with flange and nut set tight, people must be the center hole of the blade and is firmly fixed on the flange, according to Taiwan after installation, gasket sets must be purchased after a good hand gently push the blade when the washer confirm whether the eccentric rotation shaking. 5 job to be cut before use after installation Alloy saw pre-turn for a minute, until the machine into operation. 6, when the non-automatic cutting operation, you must gently cut into the normal operation of the blade material is prohibited Forced straining hard to push. And prohibit reverse ban suddenly stopped in the middle of the blade material is cut, otherwise lead to jagged off, saw  GUSHI concrete polishing pads body deformation, prone to danger. 7, using hear abnormal sounds, see abnormal shaking or section does not usually stop the job and find the cause of the exception, the timely replacement blade. 8, please wipe the rust after cutting oil, to prevent the blade is not used for a long time and rust. 9, insert the blade perpendicular to the tool holder to hang in a dry, avoid damp areas. Do not place the blade flat on the ground, otherwise easily lead to blade deformation. Do not directly stacked multi-chip saw blade should be spaced packaging to avoid jagged collision should gently. 10, again when the blade is not sharp serrated grinding, grinding is not easy to destroy serrated timely original angle, the impact of cutting accuracy and shorten blade life.
First, how to choose the right blade?
1, the basic data: ① machine spindle speed, ② workpiece thickness and material, ③ saw blade diameter size and pore size (shaft);
2, selected on the basis: the number of revolutions of the spindle and intends to match the outer diameter of the blade computing, cutting speed: V = π × outer diameter D × revolutions N/60 (m / s) is generally reasonable cutting speed 60-90 m / second,
Specific recommendations:
Material cutting
Softwood 60-90 (m / s)
Hardwood 50-70 (m / s)
Particleboard, plywood 60-80 (m / s)
Cutting speed is too large, machine vibration, voice large blade stability is reduced, degradation processing, cutting speed is too small, reducing production efficiency. The same feed rate per  tooth cutting increased, affecting the processing quality and life of the saw blade. Because the blade diameter D and spindle speed N is a power function, in practical applications, a reasonable increase speed and reduce the diameter GUSHI diamond polishing tools  of the blade is most economical.
3, quality bid:
As the saying goes: "not good goods cheaper, better goods are not cheap," probably true for other commodities, but it is probably not the right tool tools Sure; crucial match. Job site on many factors: such as sawing device object, quality requirements, quality of personnel. Comprehensive assessment, rationally choose the best use, just right in order to save money, reduce costs, participation in the competition. It depends on the expertise of similar products and understand the information.

Comparison with amorphous diamond CVD diamond grinding wheel

( 1 ) the difference between the amorphous diamond CVD diamond grinding wheel
   Amorphous diamond ( also called diamond-like carbon - Annotation ) is to adopt a carbon PVD coating deposition process . It has part of the diamond , but also has a part of SP2 carbon bond ; its high film hardness, but lower than the hardness of diamond films ; their  concrete polishing pads thickness than we usually deposited diamond film to be thinner . When machining graphite, amorphous diamond grinding tool life is 2-3 times uncoated carbide tools . Consistent contrast , CVD diamond deposition process is the use of pure CVD diamond wheel , tool life when machining graphite is 12-20 times carbide cutting tools , which can reduce the number of tool changes  diamond polishing tools to improve the reliability and precision machining sex .
( 2 ) diamond wheel life varies
  Like any other tool , diamond grinding tool life also varies , depending on the material to be cut , the choice of feed rate and cutting speed , as well as the geometry of the workpiece and the like. In general , processing of graphite diamond wheel tool life is 10-20 times uncoated carbide tools and may even longer in some cases . Thus , a tool can be done with almost any processing tasks without tool change due to tool wear and concrete ring saw  avoid the processing of the interrupt and recalibration , making it possible to achieve unattended processing. In the processing of composite materials , it is entirely possible to get a longer tool life. When it was reported in the processing of high-density glass fiber, carbon fiber composite materials difficult to machine , diamond grinding tool life up to 70 times is not coated carbide tools .

Characteristics of the diamond wheel to decide what

Diamond Wheel is a highly professional product, very few non-professionals for its understanding. Characteristics of the diamond wheel to decide what the majority of users are concerned , but also troubled by a user of important issues. Professionals that features a good diamond wheel is determined by the following factors:
By the characteristics of the abrasive wheel , grain size, hardness , binders , shape and other factors to determine abrasive grinding wheels  the size of the abrasive particle size selection , primarily related to the surface roughness and productivity . When roughing , grinding margin, requires a larger surface roughness values ​​should be used in coarse grains . Because coarse grains , large pores , grinding depth can be larger wheel clogging and fever. When grinding , margin is small, requiring a lower roughness values ​​, you can select finer grit . Generally speaking , the more fine abrasive grinding surface roughness as possible.
Concentration of diamond grinding wheel selection we understand the concentration of diamond grinding it? Refers  masonry drill bits to the concentration of the abrasive layer of the abrasive content . Today we have to say is how the concentration of diamond wheels were chosen , I hope you will like the following content.
① diamond grinding wheel generally 50 % -100 % concentration ; most 75% , the time required to finish higher than 75 %, forming the grinding wheel and requires a long life , can be 100% or more ;
② diamond products in general use 25% -150 % concentration ; cutting blade which coarse-grained , concentrations are concrete saws  generally higher than at the end , that is 25-50 % higher fine-grained ; while other metal bonded grinding wheel generally requires concentration to 50 % to 100 % concentration . Overall, with a higher concentration of coarse , semi- fine grinding with a moderate concentration , and grinding and polishing with a higher concentration .

Resin grinding wheel can not be stored in damp places

Insist on using the FIFO principle , be used during the best use to ensure wheel, resin grinding wheel use during the warranty period , if more than one year will need re-testing its strength and appearance , may continue to use the check. Wheel, resin grinding wheel requires a full , tight packaging , so as to ensure that transportation to and from the course without collisions. During transport needs careful not to get wet , away from alkalis items. Resin wheel to wheel and usually square and placed neatly , try  concrete ring saw not to tilt, do not let their pressure and prevent deformation. Wheel in the store when the use of wooden pallets Gechao mopping -out , avoid direct contact with the ground , from the ground requires 10cm to 15cm, the maximum height does not exceed 1m. The company has advanced production equipment and first-class technology . Product quality and perfect after-sales service , the main production and operation : ceramic grinding wheel, resin grinding wheel , abrasive series and other electrical products.
The wheel up from the melt rotation , relying on rotating grinding wheel blows excess impregnant . Whetstone holding abrasive grinding wheels  time in the air for 1-1.5 hours . Wheel according to this specification discard excess impregnant not formed on the diamond trimming the tumor , while the grinding surface of the plug is not greasy , and will not produce burns on the surface to be ground . Vintage stearyl wheel and immersion treatment is sulfur impregnation of the substrate to process a variety of wheel technology, can improve grinding performance, but there are some defects in the process of handling the final result is often used to reduce the effect of wheel . Our analysis of the reasons that these components can form a homogeneous melt , stearyl distributed above and below the sulfur distribution in  tile cutting blades contrast , modern technology is dipping treatment on the development of conventional treatment , were then placed in was heated to 130-135 ℃ impregnant composition in the melt , from 2.8 rpm / sec to stop the fall of the pulse with the rotation speed of four minutes . This will ensure that all components of impregnation evenly soaked in the wheel .
