Briefing

PCBN is characteristic of high hardness, high wear resistance and high thermal stability.

Detailed

PCBN is characteristic of high hardness, high wear resistance and high thermal stability. It’s inert to iron family element, hence PCBN is mainly used for the machining of high hardness and hard processed ferrous materials, such as harden steel, pearlitic gray cast iron, high temperature alloy, high-speed steel, hard facing alloys, Ni-Cr alloy, powder metallurgy metals.

Our PCBN blanks for cutting tools have two series of CB and BN. CB series is composed of CBN layer and tungsten carbide base. BN series is solid CBN. Customers can choose suitable PCBN material with different CBN contents, grain sizes and grades according to turned object material.

In general, high content PCBN is used in cast iron applications while low content PCBN is used in hardened steel applications.
