Introduction of cutting disc 1 Abrasive is a sharp, hard material used to grind the surface of the material. Abrasives are available in two categories: natural abrasives and synthetic abrasives. Many natural abrasives have been replaced by artificial abrasives. Generally, alumina, zirconia, silicon carbide, etc. are commonly used. 2 Cutting discs are tools for grinding, grinding and polishing. Most of the cutting disc for stainless steel are artificial cutting discs made of abrasive plus binder, and natural cutting discs directly processed from natural mineral rock. In addition to being widely used in machinery manufacturing and other metal processing industries, cutting discs are also used in the processing of food processing, the paper industry, and non-metallic materials such as ceramics, glass, stone, plastics, rubber, and wood. Here we mainly talk about the widely used cutting discs, which usually include two types: ordinary cutting discs and superhard material cutting discs: A common cutting disc refers to a cutting disc made of ordinary abrasive. According to the abrasive combination form, it is divided into a fixed cutting disc and a coated cutting disc, which can be divided into ceramic cutting discs and resin cutting discs according to different bonding agents. 2 superhard material cutting disc, mainly made of metal powder, metal oxide or CBN superhard material as filler, resin bond or ceramic bond or metal bond.
