The invention relates to an electrochemical
polishing method for a bearing
retainer. The electrochemical
polishing method for the bearing
retainer comprises the steps of: preparing, electrochemical
polishing,
electrolyte mixing, cleaning by using cold water, passivating, cleaning by using hot water,
drying and
rust preventing; the
electrolyte is prepared from
phosphoric acid, water and
chromic anhydride in a volume ratio of 8:4:1; the temperature of the
electrolyte is controlled to be below 40 DEG C; in the electrochemical polishing step, the
current density is 35A /
square decimeter, the working
voltage is 8-10V, the distance between the negative pole of an electrochemical polishing
machine and a processed workpiece is 5-10mm, and the electrochemical polishing time is 90s; the preparing step comprises the sub-steps of: preparing the electrolyte, adding the electrolyte in an electrolytic vessel, placing a
lead plate in the electrolytic vessel, connecting the
lead plate and the negative pole of the electrochemical polishing
machine, and preparing the processed workpiece; and the step of preparing the processed workpiece comprises the following sub-steps of: performing oil removing and cleaning on the processed workpiece, cleaning by using hot water, cleaning by using cold water, hanging on a hanger, and connecting the processed workpiece with the positive pole of the electrochemical polishing
machine. According to the electrochemical polishing method, the clamping as well as the material charging and discharging are convenient, the occupying area is small, the cost is low, the burr removing effect is good, the labor intensity is obviously reduced, and the time and the labor are saved.
