Introduction: Cubic boron nitride (CBN) is the second hardest material in the world invented successfully inl957; the microhardness of CBN's single crystal is HV8000-9000 while the hardness of PCBN is HV2500-5000, so it is considerably better abrasive resistance than cemented carbide and ceramics. With a higher ability of oxidation resistance within 1000 °C, CBN will not have any chemical reaction with ferrous material at 1200-1300 °C. So it is unique for CBN material dry cutting ferrous materials. The principal application areas for CBN cutting tools are hardened steels, cast irons and...
