Experimental Research on Rolling Bearing Raceway Finishing

Abstract:

The machining quality of rolling bearing raceway has an important impact on bearing life. In this paper, the finishing experiment equipment of rolling bearing raceway is built and the mechanical and electrochemical mechanical experiments are conducted. The impact of clearance between cathode and workpiece, the rotation speed and the abrasive grain size on electrochemical mechanical machining quality is analyzed. The surface roughness decreases from Ra0.20μm to Ra0.04μm through electrochemical mechanical machining. The surface morphology of workpiece after finishing is observed. Contrast with the surface morphology after conventional mechanical polishing, the surface after electrochemical mechanical finishing is more suitable to the bearing raceway.
