PCBN Tools

PCBN, also referred to as CBN, is most commonly used in the machining of extremely hard and/or abrasive materials.

Typical PCBN Cutting Tool Applications

Powdered metals
Sinter hardened
Steam treated
As-sintered

Hardened steel
Alloy Steels
Tool steel

Cast iron
Class 30 Grey Iron
Heat Treated
Ductile Iron

Cutting Tools Materials History

Before 1879, most of the industrialised countries were only familiar with high-carbon steel forged tools containing about 1% carbon and 0.2% managanese.

In 1900. F.W. Taylor and M. White developed HSS giving a cutting speed of  60 fpm.

in 1920, Germans introduced tungsten carbide.

In 1941, German develop an alternative to tungsten carbide and developed ceramic (oxide) tools material.


Cutting speeds were increased steadily in the machining processes due to various researches. Presently highest cutting speeds are obtained with polycrystalline Diamond tools. 1800 metres per minute are obtained in typical applications. Even 2100 metres/min was possible with free machining and nonferrous materials.
