Abstract

In this study, we have performed efficient and high-precision grinding of cemented carbide alloys with a newly developed grinding wheel, and investigated the ground surface characteristics in detail. The processing results showed that final finishing using the Chromium bonding #8000 wheel produced an extremely smooth ground surface roughness Ra of 4 nm. And, the Cr-series exhibits a strong chemical adhesion because the Cr elements that penetrated and diffused into the substrate during the machining process have a strong chemical affinity with the DLC film.
