PCBN tool wear standard

I. INTRODUCTION Like the cutters of other materials, the cubic boron nitride sintered body (PCBN) tool also has the problem of tool wear in the processing of hard-to-machine materials such as hardened steel, die steel and wear-resistant cast iron with hardness greater than HRC45. . Master the wear standards of PCBN tools, for the better use of PCBN tools, to ensure processing quality, extend tool life, minimize tool use costs, are very
