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.

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.

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.

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.

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.

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 .

About the multi-chip saw blade aperture , tooth and coating

Multi-chip saw blade aperture
Multi-chip saw blade aperture of course, first look at the requirements of the machine , because it is a multi-chip installed together , in order to ensure stability, the general design of the aperture is larger than conventional blade aperture , the aperture while the Concrete saw blades  majority of the increase , plus a special method of installation Flanges and keyway design to facilitate adding coolant , but also increase stability. General 110-200MM blade aperture between the outer diameter of 35-40 ,230-300MM blade aperture between the outer diameter of 40-70, 300MM over the blade is generally less than 50MM.
Multi-chip saw blade tooth
Multi-chip saw blade tooth is generally around the turn of the teeth , but a few small diameter blades are also designed to be flat teeth .
 Multi-chip saw blade coating
After the multi-chip saw blade welding grinding is completed, usually coating treatment , reportedly can extend life, it is mainly for blade looks beautiful, especially in multi-chip saw blade with scraper, welding current level , scraper Department has very obvious traces of welding , so before coating treatment , in order to maintain appearance. Plus multi-piece welded carbide saw blade on the saw blade matrix , collectively scraper. General core bits for concrete  since the beginning of the scraper blade outer scraper blade and teeth , the cutting blade is generally used for hardwood , wet outside scraper generally used for cutting wood , tooth scraper used for trimming or edge blade , but can not be generalized . Rui Shi to multi-chip saw blade , for example, the general design of the blade 10 inches below the number of 2-4 , in order to allow the blade play the biggest role , mostly designed for outer blade , 12- inch blade design and the number of 4-8 inner and outer blade scraper each half , symmetrical design . Multi-chip saw blade with scraper is a  4 inch saw blades trend of foreign companies before the invention of the earlier multi-chip saw blade with a blade . When cutting wet wood and hardwood , in order to achieve better cutting effect , reducing tooth paste blade burning piece of machinery to increase chip capacity, reduce the number of grinding and increase durability. However , multi-chip saw blade with a blade grinding difficult , generally can not be grinding equipment , the price is also relatively high .

The chemical composition of the diamond and the causes

Diamond is one of many married women must have a baby in mind, this is actually a diamond diamond. This diamond and diamond saw we say what does it matter? A senior quality natural diamond, a diamond for industrial use, poor quality, it may be artificial, but one thing wood band saw blades  is the same: their hardness. Diamond is one of the hardest metals, natural form so hard, but why such a beautiful stone?
First, the chemical composition of the diamond
To understand the formation of the first to know his diamond chemical composition. The chemical composition of the diamond is carbon, which is the only single-element in the gem. Is isometric crystal system. Crystal form mostly octahedron, rhombic dodecahedron, tetrahedron, and their poly shape. Pure colorless diamonds, the mixing of trace elements present different colors. Strong adamantine luster. 2.417 refractive index, dispersion medium, 0.044. Homogeneous body. Thermal conductivity of 0.35 cal / cm? Sec? Degrees. Thermal conductivity meter test, the reaction is most sensitive. Hardness of 10, is the hardest known mineral, quartz absolute hardness is 1000 times, 150 times corundum, fear, hit after hit will be broken along its cleavage. A cleavage completely. Density 3.52 g / cc. Diamond has a luminous, the  Plate Compactor sunlight, the night can emit phosphorescent light cyan. X-ray irradiation, emit blue fluorescence. Diamond is chemically stable at room temperature is not easy to dissolve in acid and alkaline, acid does not produce its effect.
Diamonds and similar gems, synthetic diamond distinction. The gemstone market common substitutes or fake colorless stones, colorless spinel, cubic zirconia, strontium titanate, yttrium aluminum garnet, yttrium gallium garnet, synthetic rutile. Synthetic diamond was first developed in 1955 by the Japanese success, but mass production. Because synthetic diamonds than the high cost of natural diamonds, synthetic diamonds on the market so rare. Diamond its unique hardness, density, and dispersion, the refractive index difference may be similar thereto gems. Such as: Fangzuan cubic zirconia and more colorless, strong dispersion (0.060), strong luster, density, 5.8 g / cc, weigh heavy hand feel obvious. Yttrium aluminum garnet dispersion soft, it is difficult to visually distinguish the diamond.
It has become the people who can stone polishing pads  own, wear mass gems. Diamond's culture and long history, more people today see it as a symbol of love and loyalty.
Second, the causes
These components together is how to become a diamond it? Modern science and technology, the means to explore the formation of diamond provides new ideas and methods. Diamonds are the hardest in the world, the most simple ingredients gem, which is composed of carbon, and a natural cubic crystal structure.

As abrasive wheel itself has high hardness and heat resistance

 As intense friction, leaving the grinding zone temperature is high. This will cause the workpiece to produce stress and deformation of the workpiece surface and even cause burns. Therefore, a  dry polishing pads lot of grinding coolant must be injected to reduce the grinding temperature. Also from the coolant and lubrication chip.
Grinding large radial forces. This will cause the machine - grinding wheel - workpiece system flexibility retreat, the actual depth of cut less than the nominal depth of cut. Therefore, the grinding will be completed when the light is not to be infeed grinding to remove the error.
After blunt abrasive, grinding force also increased, resulting in grain crushing or off, re-exposing the sharp abrasive grinding wheels  edge, this feature is called "self-sharpening." Self-sharpening of the grinding head in a certain period of time to normal, but over a certain working time should be performed after manual trimming, grinding force increases so as to cause vibration, noise, and damage the workpiece surface quality.
As abrasive wheel itself has high hardness and heat resistance, high hardness can be processed so grinding materials such as hardened steel, carbide, etc..
Determine the characteristics of  abrasive grinding wheels the grinding wheel and grinding grinding system can make even a trace cutting, general ap = 0.001 ~ 0.005mm; grinding speed is high, generally up to v = 30 ~ 50m / s; grinder stiffness; adopts hydraulic transmission, Therefore, grinding can be obtained economically with high precision (IT6 ~ IT5) and a small surface roughness (Ra = 0.8 ~ 0.2μm). Grinding is one of the main methods parts finishing.

Use some method of diamond tools

Diamond cutting tool is mainly processing of non-metallic materials of high hardness , scope more widely, then we use diamond tool tips when you do what ? 1 , different specifications and uses of the blade , the blade angle and the design matrix forms are different, as far as possible according to their corresponding occasions ; 2, the device spindle and plywood size and shape and position accuracy with the results there are influence , installation and adjustment to be checked before the blade . Especially iamond tools manufacturer  for plywood blade contact surface with the impact caused by the clamping force to slip displacement factors must be excluded ;
3 , pay attention to the work of the blade , an exception occurs, such as vibration, my voice , machined surface material moving situation, you must promptly stop adjustment , and timely grinding, maintaining peak interest ;
4 , grinding blade must not change its original angle , to avoid sudden thermal quench local head , the best professional grinding
  Diamond tools with high hardness and wear resistance , low friction coefficient, high elastic metal drill bits  modulus , high thermal conductivity , low thermal expansion coefficient, and low affinity and non-ferrous metals and so on. Can be used for non-metal brittle materials such as graphite , high wear-resistant materials , composite materials, high toughness silicon aluminum alloy and other non-ferrous materials, precision machining . Many types of diamond tools , the performance difference was significant , the structure of different types of diamond tools , method of preparation and application areas is quite different .
Within a certain range , when the diamond concentration changes from low to high , the blade sharpness and cutting efficiency carbide tipped saw blade  decreased, while life is gradually extended ; but the concentration is too high , the blade becomes blunt . The use of low concentration , coarse , efficiency will be increased . The use of various parts of the cutting head when the different roles of different concentrations ( i.e. three or more layer structure in the intermediate layer can be used in low concentrations ) , the saw blade during the work head to form an intermediate groove , with helps prevent blade deflection , thereby improving the quality of stone processing .

How to replace the worn drill

Bits in underground work after a certain time, scraper blade drill a smaller diameter, shorter, blunt, rock crushing capacity will become weak, progress slowed down. Tags: Geological coring drill bit concave three wings
Bits in underground work after a certain time, scraper blade drill a smaller diameter, shorter, blunt, rock diamond bandsaw blades  crushing capacity will become weak, slowed down progress; cone drill because tooth wear erosion, bearing damage, can cause cone rotation is not flexible or cone stuck, the torque increases, if not promptly fall from the cone accidents will happen; diamond drill due to the heterogeneity caused by the formation of the PDC drill occurred crack, break, out , also makes drilling footage slower. To speed up the whole well drilling speed, must be replaced with the old drill and drill bit is a few hundred meters to several kilometers underground, how to replace the drill rig workers do?
Drilling rig power driven turntable, kelly, drill and drill bit rotates through observation instrument ground rig drill underground work, as consolidated judgment, if that bit has been worn, replace the drill bit should immediately stop drilling . After stopping drilling to  tile cutting blades continue to maintain the drilling fluid circulation for some time, the purpose is to adjust the performance of the drilling fluid and the cuttings suspended in the fluid out of the ground, the loop so that the new wellbore wall remained stable, while also To carry out routine inspections of drilling equipment. Workers use derrick drilling crown block, traveling block and hook, according to the height of the derrick by column (generally composed of two or three drill) from drilling wells up out of all. After the drill column from the discharge order in the derrick, the proposed downhole drill string while continuing to use the drilling pump perfusion fluid annular space, the  concrete cutting blade purpose is to keep the wellbore fluid level does not drop, the wellbore pressure to balance the formation pressure to prevent borehole collapse or underground formation fluid into the wellbore. Meanwhile, we should pay particular attention to the reduced diameter borehole sticking may occur, the operator must be strictly controlled to enhance speed. All within the wellbore drill pipe, drill collars, after starting out, the need to replace the drill will also act out the workers after removing the old drill press fitted with the new drill down to the original column order can be restored after drilling wells .

quality control has guiding significance

Sheet wheel performance depends largely on the merits of using abrasive quality, good quality abrasives, grinding wheels, high grade, and in the more expensive price. As the domestic high-grade bauxite resource depletion, a variety of raw materials and coal prices in mid-rise, coupled with energy saving the environment forced shut down, corundum prices are cutting discs  rising fast, from time to time will be in short supply. How rational use abrasives, improve market competitiveness, is the most important enterprises grinding technology considerations.Best approach is to not participate in the core sheet wheel portion of the cutting action of poor quality with low prices instead of secondary abrasive, abrasive cutting quality full performance, lower manufacturing costs. This approach resin bolts and large diameter cylindrical grinding wheel resin grinding wheel has been widely used. For thin grinding wheel, since the intermediate screening, the bottom and the top to separate the feed, if the external and the core are bandsaw blades  stepwise feeding, in the process to implement quite difficult, is still only vision in the future, if successful, cost reduction, profit improvement , on sheet wheel manufacturing is undoubtedly a far-reaching "technological revolution."Compare prices now wear suitable strategy for various consumer groups, in accordance with abrasive made of different grades of abrasive products, the best abrasive used in most need sheet wheel, avoiding production of low-grade abrasive grinding wheels with high-grade, as far as possible best use, cost-effective in improving the premise, a great effort for each grade of the product have done "extreme."High-grade sheet wheel stable, targeted, reproducible tamping rammer  production has generally adopted a sand, special products and even to use zirconium corundum, calcined alumina abrasive and post-processing. The market is dominated by imported products, most cost-effective production of high sheet is not high, not discrimination, targeted not strong, still need further research and development efforts.

Process for producing diamond saw blade can be described as necessary

 Diamond saw blade manufacturing process what is it? Below to learn more about it!
Process for producing diamond saw blade can be described as necessary under pressure in metal powder sintering process, a powder metallurgy process: metal powder mixed dish symmetry at high temperature (800-1000 ℃) and the inevitable pressure (180 - 250Kgf/cm2), through the diffusion between the powder particles, welding, compounds, recrystallization and  carbide saw blades the like a series of physical and chemical impregnation, has a certain shape to form a sintered body and the machine functions, namely head.small blade used Precautions When using the saw, there must skids, and in the hands or feet fixing the other end of sawing wood to produce unexpected slip roll, saw themselves need to maintain smooth, do not bend, so the saw body deformation. If you saw a oiled, it certainly erased after the first oil used. When used to pay attention to the direction of force saws, saws launch force, back when the relaxation. Aperture selection apertures are relatively  brick saw blades simple parameters are mainly required by the device options, but in order to maintain the stability of the blade, 250MM best selection of aperture blades above larger device. At present, the design of standard aperture, 120MM and below, mostly in diameter 20MM Kong ,120-230MM mostly 25.4MM Kong, more than 250 multi-aperture 30, some of the imported equipment has 15.875MM hole, multi-chip saw relatively complex mechanical aperture , mostly with keyway to ensure stability. Regardless of pore size, can be transformed through the sds drill bits  lathe or EDM, lathes car washer can be set in a large aperture, EDM can reaming necessary requirements for the device.
Alloy head type, substrate material, diameter, number of teeth, thickness, tooth, angle, aperture and a series of parameters combined into a whole hard alloy saw blade, to a reasonable choice and match in order to better play to its strengths.

electroplated diamond

 The main difference is the type of binding agent: resin bonded diamond grinding wheel mainly phenolic resin and a small amount of metal powder as a binder, and electroplated diamond grinding wheel is a crack chaser  method by electrodeposition of nickel-cobalt alloy is deposited on the metal substrate surface and fixed to a diamond abrasive wheel production process.Their performance on the main difference is:1, in the processing efficiency, due to the use of higher grade plating abrasive grinding wheel and only one layer of abrasive, thermal performance and so have their own advantages, so the more efficient processing of electroplated diamond grinding wheel;
2, service life, only one layer  concrete core bits of abrasive grinding wheel plating, the plating wheel life will be inferior resin diamond grinding wheel;
3, machining accuracy, surface roughness of the workpiece the impact, the same case size, plating out of the surface roughness of the grinding wheel to be worse.Second, at the same time, but also because it has a fast heat dissipation characteristics, so in grinding large number of heat-sensitive materials, thin-walled workpieces and dry milling process (eg rail grinding carbide cutting tools and machine tools, etc.) with good results.

to prevent the circular blade hardness is low and how to make the circular blade wear durability

Let's say the first choice, how to make circular blade hardness to achieve the best state, is a circular blade hardness and toughness to achieve the perfect value!
(A) heat treatment process in strict accordance with operating procedures, frequently check the gun temperature heat treatment equipment and instruments, such as the working status.
(2) In the quenching apparatus, the cooling medium is loaded in the circulation or agitation, to improve the cooling capacity of the quenching medium and uniformity.
 (3) on carbon tool steel and alloy tool steel circular blade, always check its hardness after quenching. Pair of high-speed steel circular blade, always check its quenched microstructure.
(4) Set monitor temperature control to prevent tempering temperature (temperature tempering run).
(5) to ensure the circular blade (including the blade) performance under the premise, according to the circular blade structure and size selection with the proper hardenability of steel.
(6) strict control of the chemical composition of  drill bits the steel and the original organization, plus 9 Steel management to prevent steel mixing.
(7) strictly in accordance with specifications for grinding circular blade grinding
  Two: how to use the circular blade will wear durability
    1, the selection of materials.
Choice of materials is an important step, the selected material is aligned with the customer cut and abrasion resistance of materials use the appropriate materials, materials selected is not good, a direct impact on the use of blade life.
2, the casting process
Air hammer steel casting eliminate occurred during a workout loose and vague and other shortcomings, the usefulness of ceramic tile saw  forging raw data is to make more solid circular blade.
3, the heat treatment process
Heat treatment process is a very important quality in production order, the customer and swap chipping mentioned port is the primary reason that the heat treatment. Effect of heat treatment of the circular blade material promoted higher hardness.
4, the machine processing steps
Based on customer requirements, we use cutting discs  sophisticated tools to right circular blade material thickness, parallelism, flatness, cylindrical, inner circle such as to make the product. Thickness Gongyi guarantee within the ± 0.0005mm. View product of all precision in temperature indoors.

carbide saw blade quality and quality of processed products are closely related

Carbide saw blade containing the type of alloy, the substrate material, diameter, number of teeth, thickness, profile, angle, diameter and other parameters that determine the processing capacity grinding cup wheels  and cutting blade. Select the saw blade sawing according to the type of material, thickness, cutting speed, cutting direction, feed speed, kerf width requires the correct selection of blades.
(A) the choice of carbide species
Commonly used types of tungsten carbide cobalt (code YG), tungsten titanium category (Code YT). Since tungsten carbide cobalt impact resistance is better in the wood processing industry more widely used. Commonly used in wood processing model YG8-YG15, YG behind the numbers indicate the percentage of cobalt, cobalt content increases, the alloy impact toughness and flexural strength has increased, but the hardness and wear resistance has declined, to be selected according to the actual situation.
(B) the choice of substrate
1.65Mn spring steel elastic and plastic, material economy, good hardenability, the heating temperature is low, easy deformation can  General purpose blade be used for less demanding requirements of the cutting blade.
(2) high carbon tool steel carbon high thermal conductivity, but by the temperature of 200 ℃ -250 ℃ sharp decline in its hardness and wear resistance, heat deformation, poor hardenability, tempering longer easy to crack. Materials such as tool manufacturing economy T8A, T10A, T12A and so on.
3 alloy tool steel and carbon tool steel, heat resistance, wear resistance, good processing performance, heat distortion temperature of 300 ℃ -400 ℃ suitable for manufacturing high-grade alloy circular saw blades.
4 high-speed tool steel has good hardenability, hardness and rigidity, less heat deformation, is ultra-high strength  core bits for concrete steel, high-grade thermoplastic stable suitable for manufacturing thin blades.
(C) the choice of diameter
Saw blade diameter with the use of cutting equipment and cutting the workpiece thickness. Saw blade diameter is small, the cutting speed is relatively low; Saw blade diameter and sawing equipment requirements for the necessary high, while the cutting efficiency is high. Depending on the diameter of the blade circular sawing machine model selection with a diameter matching blades.
Standard parts diameter: 110MM (4 inches), 150MM (6 inches), 180MM (7 inch), 200MM (8 inches), 230MM (9-inch), 250MM (10-inch), 300MM (12-inch), 350MM ( 14-inch), 400MM (16-inch), 450MM (18-inch), 500MM (20-inch), etc., precision panel saw blade multi bottom slot designed to 120MM.
(D) selection of teeth
Serrated teeth, in general, the more teeth, in the unit time, the more the cutting edge, cutting as possible, but the number of cutting teeth carbide required more and more, the high price of the blade, but too close serrated , teeth of the chip becomes small, easy to cause the blade fever; another jagged too, when the feed rate mis-match, then cut each tooth small amounts, will exacerbate friction with the workpiece edge, affecting the life of the blade . Typically tooth spacing 15-25mm, material selection should be based on a reasonable cutting teeth.
