Reasonable use of grinding wheel

To process different workpiece materials and meet different processing needs, it is necessary to choose different grinding wheels. There are many types of grinding wheels, grinding wheels with different bonding agents and different hardnesses. It is most important to choose the appropriate grinding wheel according to the actual situation.

Diamond grinding wheels are the best abrasive tools for grinding high-hardness and brittle non-metallic materials such as cemented carbide and ceramics, optical glass, gemstones and stone. However, since diamond is easily carbonized at 700 ° C to 800 ° C, it is not suitable for grinding steel with a large amount of iron. The hardness of CBN is slightly lower than that of diamond, but its thermal stability is good (can withstand 1300 ° C ~ 1400 ° C high temperature), chemical inertity with iron elements, high thermal conductivity (46 times that of corundum), made with it The grinding wheel has a long service life (up to tens of times to more than one hundred times of the corundum grinding wheel). It does not decompose at high temperature like diamond (ie oxidation and graphitization). It is an alternative to corundum grinding wheel for hardened steel, bearing steel and high speed tools. The best abrasive tool for high hardness and toughness metal materials such as steel, stainless steel, heat resistant steel and titanium alloy.

Bonding agents for diamond wheels are resin, metal, ceramic, electroplating and brazing. According to the actual use, the selection of diamond grinding wheels with different bonding agents is crucial for grinding efficiency and grinding quality.
