This kind of electrolytic polishiing is normal used in stainless steel like SUS316, 316L,304 etc, requiring surface no rusty and have a dense protectors.

We shandong no2 machinery company often use this polishing because customers requires.

Its advantages are long mirror gloss, stable process, less pollution, low cost and good corrosion resistance. Its shortcomings are huge one-time investment in processing equipment; big and complicated parts need tooling; auxiliary electrodes; and large-scale production also needs cooling equipment. It is suitable for mass production, mainly used for high-grade, export products. Its processing technology is stable, relatively simple operation.

The basic principle of electrolytic polishing is similar to that of chemical polishing. That is to say, to dissolve small protruding parts from the parts surface so that to make parts polishing. Compared with chemical polishing, the effect of cathode reflection can be eliminated and the effect is better.

The electrolytic polishing process is divided into two steps:

(1) Macro leveling the product surface, then, dissolved products disperse into the electrolyte, and the geometrical roughness of the material surface decreases to Ra1 micron.

(2) Low-light level anodic polarization improves the external brightness and Ra to 1 micron.
