1.Mechanical polishing : reach to a surface roughness of Ra0.008um
2.Chemical polishing : usually a couple of Ra10um
3.Electrolytic polishing : compared to the chemical one, electrolytic polishing could eliminate the negative effect of cathodic reaction;
4.Ultrasonic polishing : the cavitation effect of ultrasonic wave in liquid can inhibit the corrosion process, which is beneficial o surface lighting.
5.Float polishing
6.Megnetic abrasive polishing : high efficiency, good quality, the processing conditions are easy to control. With proper material, the surface roughness could be reached to Ra0.1um.
