The characteristics of electrolytic polishing are:
(1) the surface of polishing will not produce deterioration layer, no additional stress, and can remove or reduce the original stress layer.
2. Hard materials, soft materials and thin walled, complex and fine parts and products that are difficult to machine polishing can be machined.
3. Polishing time is short, and many parts can be polished at the same time, and the production efficiency is high.
(4) the surface roughness of electrolytic polishing is related to the original surface roughness, and generally can be increased by two.
However, due to the poor versatility of electrolyte, short service life and strong corrosion, the application range of electropolishing is limited. Electrolytic polishing is mainly used for metal products and parts with small surface roughness, such as mirrors, stainless steel tableware, ornaments, injection needles, springs, blades and stainless steel tubes, and can also be used for polishing of certain moulds (such as glue wood mould and glass mould, etc.) and metallographic abrasive.
The metal ions separated from the workpiece and phosphoric acid in the polishing liquid form a phosphate film on the surface of the workpiece. The mucous membrane is thinner in the protruding, thicker in the concave, fast dissolved in the high current density at the protruding, changing with the mucous membrane, and the rough surface is gradually leveled.
The workpiece is the positive pole of the anode connected DC power supply.  The conductive materials, such as lead and stainless steel, which are corroded by electrolyte, are used as cathodes to connect the negative pole of the DC power supply. In a certain distance, the two are immersed in the electrolyte (generally with sulfuric acid and phosphoric acid as the basic component). At a certain temperature, voltage, and current density (generally below 1 AMPS / cm 2), a certain time (usually tens of seconds to several minutes) is electrified, and the minute protruding parts on the surface of the workpiece are dissolved first, and gradually become smooth and bright surfaces. .
