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.
