Electro-polishing and chemical polishing work can be done separately from the surface treatment method instead of mechanical polishing, or it can be used to prepare before plating. However, this method has a certain degree of surface dissolution and may eliminate some sharp edges on the profile, so the size and shape of the margin should be taken into account.

Electro-polishing and chemical polishing in addition to the surface can give a smooth and shiny, but also other application effects. Such as the use of this method to eliminate the surface of the cold hardening layer, reduce the roughness, improve friction and reduce wear, improve permeability and reduce magnetic consumption, remove sharp edges and eliminate burrs, exposure to microstructure and to check the fine Cracks and material defects and so on. The cracks and hairlines of the material are easily exposed when the material is polished, so it is also useful for testing such defects.

Electro-polishing and chemical polishing and the usual mechanical methods are different, the effect of polishing is actually related to the surface of the material. And the polishing process is usually accompanied by dissolved, so it should not be thrown too long. The speed of polishing is also very fast and is very effective in saving labor.

This method is more suitable for the final finish rather than rough throw, and thus with the initial mechanical processing with the application of better results. Chemical polishing is necessary to save the power and current distribution equipment required for electropolishing, especially since the current density for electro-polishing is often high. But chemical polishing is more affected by the surface texture of the material, and therefore not every case is very easy to use. Generally used to do the final increase in light-based processing.

The basic electrolytic polishing solution is a versatile polishing solution known as triac. This mixed acid can adapt to many different materials, such as stainless steel, ordinary steel, copper, aluminum and other non-ferrous metals. If the material is biased, you can increase or decrease the amount of the components, or add some additives.
