⑴ ceramic material because of its excellent properties such as high hardness, high wear resistance, high temperature resistance, corrosion resistance, high stiffness til granite cutting wheels to weight ratio concrete cutting blades, density and strong chemical inertness to the scientific and industrial increasingly widespread application.
⑵ widely used high-temperature superconducting single crystal 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, with a grinding wheel which is made to solve the problem of processing of glass, ceramic material of high hardness. For the development of flap wheel new engineering ceramics such as silicon nitride, while grinding with a resin or a metal-bonded diamond wheel, the binding agent is prone to insufficient gripping force abrasive, wear increases; toughness and binding agent is too large, the grinding wheel pores less grinding force declined after blunt grinding wheel dressing is difficult, so that the entire grinding process more difficult.
⑷ quality vitrified ceramic or vitreous, binders rigid, high temperature, suitable for finishing grinding, so that the knife does not produce the phenomenon. Vitrified abrasive and strong adhesion to the edges and corners to maintain good performance, can be precision grinding.
⑸ vitrified diamond grinding wheel in the manufacturing process can be adjusted on the hardness and porosity, help to improve grinding performance through reasonable proportion and cutting grinding discs production control, no distortion, it also makes the reasons for the high precision grinding wheel .
