â‘´ ceramic material because of its excellent properties such as high hardness, high wear resistance, high temperature resistance, corrosion resistance, high stiffness to weight ratio, low density and strong chemical inertness, etc., so that in science and industry used widely.
⑵ single crystal widely used high-temperature superconducting film substrate, laser parts, the use of these new materials, due to the brittle, prone to cracking during processing, often accompanied by a large number of processing problems.
⑶ Diamond is the hardest material in nature, it is made with a grinding wheels to solve the processing problems glass, ceramics, high hardness of the material. For the development of new engineering ceramics such as silicon nitride, when grinding with a resin or metal-bonded diamond grinding wheel, prone to binding agent gripping force is not enough to abrasive, wear increases; toughness or binding agent is too large, grinding wheel small pores, grinding force decreased after grinding wheel dressing and other blunt hard the entire grinding more difficult.
â‘· vitrified ceramic or glassy substance, binders rigid, high temperature, suitable for finishing grinding, no let knife phenomenon. Vitrified abrasive and strong adhesion to the edges and corners to maintain good performance, high-precision grinding.
⑸ vitrified diamond grinding wheel in the manufacturing process can be adjusted on the hardness and porosity, and help to improve the grinding performance through reasonable proportion and production control, no distortion, it also makes the reasons for the high precision grinding wheel .
