Description

Cubic boron nitride is the second hardest material in the world invented successfully in 1957. The hardness of CBN’s single crystal is HV8000-9000 while the hardness of PCBN is HV2500-5000, so its abrasive resistance is considerably better than tungsten carbide and ceramics. With high temperature oxidation resistance at 1000℃, CBN will do not have any chemical reaction together with ferrous material at 1200-1300℃. So CBN material is ideal for cutting ferrous materials, the CBN cutting tools are used for cutting hardened steel, cast iron, sintered iron as well as powder metallurgy components.
