The polished process is a process of cutting the surface of a metal part by the rotation of a special buffing wheel (or belt) to which the abrasive is adhered. It can remove burrs, rusts, scratches, welds, welds, sand holes, oxidation skins and other macroscopic defects on the surface of parts to improve the smoothness of parts and electroplating quality. Polishing can be performed once and several times according to the surface condition and quality requirements of the parts. After polishing, the surface roughness Ra can be up to 0.4 microns, depending on the surface state and quality requirements.
