Design of Tools, Grinding Wheels, and Precision Spindles
Polycrystalline cubic boron nitride (PCBN) is a polycrystalline material obtained by sintering fine CBN material under high temperature and high pressure. PCBN tool features high hardness (4700–5000 HV), wear resistance being 50 times that of cemented carbide, thermal stability being higher than diamond, up to 1400–1500 °C, and the cutting ...
