Cutting performance of B-doped binder-less nano polycrystalline diamond

Abstract

Boron-doped nano poly crystalline diamond (B-NPD) shows high-conductivity, low coefficient of friction and thermal resistance. In order to elucidate the potential of B-NPD tools, cutting tests were conducted for some work materials under different conditions. B-NPD tools shows high potential on cutting the insulation materials without tribo-plasma. End-mill tools prepared from B-NPD using electro discharge method were examined in high precision cutting on cemented carbide mold.
