To apply Pulse Electrochemical Finishing (PECF) technology to the machining of bearing race,this paper studies the Pulse Electrochemical Finishing process of GCr15 steel (a kind of material often chosen for bearing ring),and especially discusses the influences on surface quality of inter-electrode gap size, current density,pulse parameter,electrolyte concentration and temperature detailedly. The results show that a high quality surface could be gotten when the GCr15 workpiece is machined by PECF. The conditions to get high quality surface include current density over a critical value,suitable pulse parameter,suitable electrolyte concentration and low electrolyte temperature.
