The quality standard of silicon carbide in wire cutting:
high-purity silicon carbide powder, large crystal silicon carbide and high-purity raw materials, which can ensure the excellent cutting performance and stable physical state of silicon carbide cutting powder.
The particle size is uniform, and the particle shape is equal area and sharp, which ensures the uniformity of silicon carbide powder as a cutting material. This ensures that the TTV of the material being cut is minimized. The most important thing in the cutting process is the particle shape of the silicon carbide. Because silicon carbide is in a free state during wire cutting, the shape change of cutting particles has an important impact on cutting efficiency and cutting quality.
Silicon carbide has high thermal shock stability and softening temperature under load. And it can cooperate well with the cutting machine.
The surface of silicon carbide has to be specially treated. The micropowder has a large specific surface area and a clean appearance, and has good compatibility with cutting fluids such as polyethylene glycol.
Because the hardness of silicon carbide is higher than that of corundum, diamond, cubic boron nitride, and boron carbide. In addition, silicon carbide has the characteristics of high hardness, high wear resistance, and high corrosion resistance. Therefore, silicon carbide is used in various wear-resistant, corrosion-resistant and high-temperature resistant mechanical parts.
