Effect of electropulsing assisted cutting process for quenched GCr15 bearing steel

Abstract:

Electropulsing was introduced into the cutting process of the high-frequency quenched GCr15 bearing steel. Experiment results indicate that the main cutting force, axial roughness on machined surface, surface microhardness and tool wear show a significant decreasing tendency under the effect of electropulsing. For high-frequency quenched GCr15 bearing steel, the electroplasticity effect and Joule heating effect can accelerate the movement of dislocations, then the material tempered in a lower temperature and shorter time, the plastic deformation ability and the cutting properties of GCr15 bearing steel have a remarkable improvement.
