Widely used for diamond tools

1 . The correct selection of varieties and grades blade blades of different varieties , because of its different components , cutting a big difference , and selection need to be careful. Currently carbide blade did not have a unified international classification , each has its own production plant varieties and grades should be used with reference to the manufacturers product samples to choose. Particle size can be divided  diamond saw blade  into three categories: the coarse grain ( average grain size of 20 ~ 50μm), the grains (10 ~ 20μm) and fine grain (2 ~ 10μm). The larger the grain size , the better the abrasion resistance , tool life , the higher the edge of poor quality, precision tool is made difficult . Instead, fine-grained tool cutting edge edge quality is good, good surface quality . Thus , the current grain polycrystalline continue to refine and already 1μm, 0.5μm or less even fine grain , to be based roughing and finishing processes , such as different requirements , use of different grain sizes . But our studies indicated that , in poly- crystal micro- cutting tool , it has a " multi-point cutting , forming  diamomd core drill bits a single point " feature, so long as the process to take certain measures , with coarse grains (70 ~ 30μm) polycrystalline tool also precision machining surplus can cut surfaces.
(2) select the appropriate cutting in recent years , with the occasion of the new materials, new technologies, new processes, new equipment innovations continue to emerge , such as superfine pre- alloy powder , laser processing , vacuum brazing technology , diamond plating technology, diamond uniform technology and other cutting-edge new technology, being highly Edge 2000 Pads  concerned with the key R & D , R & D results also gradually industrialized. As these research achievements in industry , diamond tool performance on continuous improvement , functionality continues to expand, currently has gradually extended its scope of application to the semiconductor , aerospace, information and many other fields, for diamond tools manufacturing enterprises to provide high profits and huge development space
