Novel batch polishing method of ceramic cutting inserts for reducing tool wear

Abstract

Abstract To reduce tool wear of inserts in cutting, this study presents an emerging magnetic field-assisted batch polishing (MABP) method for simultaneously polishing multiple ceramics cutting inserts. The wear characteristics are clarified by cutting S136H steel. The surface roughness in regard to mean height (\(Sa\)) at the flank face, edge, and nose has achieved below 2.5 nm, 6.25 nm, and 45.8 nm, respectively after 15 minutes of polishing, and the tool life was extended by 175%. The experimental results indicate that MABP is an effective method for mass polishing the cutting inserts, and the polished surfaces can notably reduce tool wear.
