Improvement of Finished Surface Roughness of Gray Cast Iron with High-speed Cutting used Binder-less cBN Tool

Abstract

Generally, high-speed cutting can improve productivity of manufacturing, while it often causes severe tool wear. In this study, the effect of finished surface property was investigated.As the result it was found that finished surface roughness was improved and the tool wear was decreased with Binder-less cBN tool. Furthermore, effect of chanfer angle on surface quality was investigated in this study.
