Process characteristics

The efficiency of electrolytic polishing is higher than that of mechanical processing, and the dense and firm oxide film is formed on the surface after polishing. It will not produce processing deterioration layer, there is no residual stress, and it is not limited by materials. It is often used in production.

Electrolytic polishing has the following features:

1, small current, large gap.

2, simple and quick.

3, oxide film from corrosion protection.

4, no work hardening and residual stress.

Application area

Electrolytic polishing can reduce the surface roughness value of parts, control the macroscopic roughness of the material, increase the surface gloss and reduce the friction factor, so it can replace the mechanical polishing in many occasions, can greatly improve the productivity, reduce the materials, tools, equipment, Consumption of electricity, etc. Electrolytic polishing has a wide range of applications in the processing of bearings, reflectors, cutting tools, metrology tools, bicycle parts, textile machinery parts, and medical devices.

When the metal surface properties of certain materials are studied in the laboratory, such as optical properties, magnetic properties, electrochemical properties, electrode diffraction properties, corrosion and friction properties, electrolytic polishing is mostly used.
