Boron Ultrahard Material
China cubic boron nitride full industry manufacturer
Polycrystalline cubic boron nitride (PCBN) superhard material tool has high hardness, good wear resistance and chemical stability, and its application in the field of automobile manufacturing has become more and more extensive.
PCBN cutting tools are made of CBN particles, which are sintered at high temperature and high pressure with or without binder.
Hardened steel is a typical wear-resistant and difficult-to-machine material. After quenching or low-temperature tempering to relieve stress, the hardness of such materials is as high as HRC45~HRC65.
