Abstract

In spite of many significant advantages of diamond coated cutting tools, rough surface with large crystal grains prevented them from usage for finishing process. In this study, a new smooth diamond coating with finely crystallized diamond on the surface was developed, whose roughness is less than 1 μm. Endmills with this coating was subjected to cutting tests for the performance of finishing non-ferrous alloys. Roughness of finished workpiece surface was less than 1 μm maximum value, which was as small as that could be achieved by using non-coated cemented carbide endmills. Anti-wear property and durability were not spoiled by these changes in coating morphologies.
