PCBN (Polycrystalline Cubic Boron Nitride)

PCBN consists of CBN and Binder. It is produced in high pressure and high temperature. It has excellent performance in hardness, wearing resistance, thermal stability.

Application: for hard ferrous materials (hardened steel, cast iron, high-temperature alloy, HSS, Powder metallurgy metals, Ni-Cr alloy...

E-Grind provides two series of PCBN:

1) Solid CBN

2) CBN with Tungsten Carbide supporting.
