Reasonable use of grinding disc
To process different workpiece materials and meet different processing needs, it is necessary to choose different high efficient metal abrasive disc. There are many types of grinding discs, grinding discs with different bonding agents and different hardnesses. It is important to select the appropriate grinding disc according to the actual situation.
Diamond high efficient metal abrasive disc is excellent grinding 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 identity with iron elements, high thermal conductivity (46 times that of corundum), made with it The long life of the high efficient metal abrasive disc (up to several hundred times to more than one hundred times of the corundum grinding disc), unlike the diamond, which will decompose at high temperature (ie oxidation and graphitization), is an alternative to corundum grinding disc hardened steel, bearing steel, high speed tool A good abrasive tool for high hardness and toughness of steel, such as steel, stainless steel, heat-resistant steel and titanium alloy.
Bonding agents for diamond high efficient metal abrasive discs are resin, metal, ceramic, electroplating and brazing. According to the actual use, the selection of diamond grinding discs with different bonding agents is crucial for grinding efficiency and grinding quality.
