PCBN

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.
