PCBN is used for the machining of ferrous materials such as, grey cast iron, carbon
steels, alloy steels, nickel or cobalt, etc... PCBN Diamond (polycrystalline cubic
boron nitride) is second only to diamond in hardness. The hardness allows the ability
to machine hardened work pieces. The high thermal conductivity of PCBN allows for
an increase in tool life over Carbide Tools. Furthermore, the high chemical stability
allows for PCBN to be stable up to 1000° C and no reaction with Fe, Ni, CO etc...
Allowing easy grinding and EDM Cutting.
