Abstract

Abstract: Through the study on cutting force, cutting temperature and machined surface quality of quench bearing steel GCr15 with vartious hardness, an influencing rule of the workpiece hardness on above parameters and chip state, hardness, deforming ratio is gained, the concept of critical hardness is put forward, and 50 HRC was confirmed as the critical hardness of hard cutting and common cutting.

Key words: Bearing steel, Critical hardness, Dry cutting, Hard cutting, PCBN cutter
