CBN grinding wheel for bearing steel
Diamond grinding wheel is a better choice for grinding hard alloy, optical glass, ceramics, gem and stone materials with high hardness and high brittleness. However, diamond is not suitable for grinding steel because it is easy to carbonize at 700℃~800℃. The hardness of CBN is slightly inferior to diamond, but it has good thermal stability (can withstand 1300℃~1400℃ high temperature), CBN is not like diamond in high temperature, that is, oxidation and grapitization, and iron group elements chemical inertia, high thermal conductivity, with its production of grinding wheels long life (up to corundum grinding wheel dozens of times to more than 100 times), It is a better choice to replace hardened steel, high speed tool steel, bearing steel, stainless steel, heat resistant steel and titanium alloy and other metal materials with high hardness and toughness.
