Paper Title:
Wear Mechanisms of PCBN Cutting Tools in Hard and Dry Cutting GCr15 Bearing Steel
  Abstract

GCr15 bearing steel was turned with PCBN cutting tools in a manner of hard and dry cutting, and the characteristics and morphology of rake and flank face of PCBN cutting tools were observed, the element distribution of different regions of rake and flank face of PCBN cutting tools were tested and analyzed by use of EDS, and finally the wear mechanisms of PCBN cutting tools were discussed. The results showed that the wear areas of rake and flank face of PCBN cutting tools were small and mostly concentrated near the tip and sub-chamfering, and the reason was mechanical, oxidation, chemical and phase transition wear, which resulted in the joint action of tool wear.
