Abstract The performance of PCBN is determined by its composition and structure. By establishing reasonable chemical conditions - chemical formula and physical conditions - high pressure and high temperature, CBN-CBN bonding is stronger than any other combination, and the grain boundary phase is the weak link of PCBN. As a result, the quality of PCBN is significantly improved, and the problem of uneven PCBN quality is also solved.
