Wear of PCBN Tool when Cutting Materials Difficult-to-Cut Based on Thermodynamics Solubility

DEStech Transactions on Engineering and Technology Research, 2017
Cutting temperature always highly reaches over to 1000℃ when high speed machining with PCBN tools. Diffusion of tool material element may have important influence on tool wear at such high temperature. The diffusion wear and oxidation wear have become the major wear mechanism.

The effect of inclusion composition on tool wear in hard part turning using PCBN cutting tools

Wear, 2015
AbstractThis work reports on hard part turning of carburizing steels using a PCBN cutting tool in fine machining. Emphasis is on the link between composition of the inclusions in work material and wear mechanisms of the cutting tool. A Ca-treated machinability improved 20NiCrMo steel was included together with three other carburizing steels with ...
