Embodiment Construction
[0013] The invention patent implements the electrolytic polishing method of the bearing cage. The equipment used includes an electrolytic polishing machine, a cooling water circulation pool, a sufficient amount of electrolyte (mainly phosphoric acid liquid), a sufficient amount of saponification cleaning solution (oil removal and cleaning link), Sufficient amount of hot water (hot water cleaning link), sufficient amount of cold water (cold water cleaning link), sufficient amount of passivation solution (passivation link), sufficient amount of antirust solution (rust prevention link), etc.
[0014] The electrolytic polishing method of the bearing cage in the embodiment of the present invention includes the following steps: preparation step → electrolytic polishing → stirring the electrolyte → cold water washing (60s) → passivation (prepared with benzotriazole and clear water with a volume ratio of 1.85:10 passivation solution, and the passivation time is 60s) → hot water washing...
