Polycrystalline Cubic Boron Nitride
Polycrystalline Cubic Boron Nitride consists of CBN grain and specific ratio of adhesive. PCBN is sintered in high temperatures and high pressure.
PCBN is manufactured by sintering PCBN particles with a certain quantity of bonding agent at high temperature and high pressure, and features excellent ductility, wear resistance and chemical stability against iron group metals, thus being frequently used for high-speed and ultra-high speed cutting and dry cutting.
