The Finishing of Rolling Bearing Raceway by Electrochemical Mechanical Finishing (ECMF) Technology

Abstract:

This paper studies the technology of Electrochemical Mechanical Finishing (ECMF) on rolling bearing raceway. The principle of the technology is introduced, and the finishing results are presented. The results show that the surface roughness, supporting length rate, profile roundness, waveness and wave velocity are all improved greatly. Also, the main affecting factors such as the inter-electrode gap, electrochemical process and mechanical process are discussed in this paper. The bearings finished by ECMF have better service performance and life.
