Abstract
Electrochemical polishing (ECP) is a promising approach to finishing surface to achieve high quality of surface. However, it cannot satisfy requirements of mirror finishing yet. In this paper, a mirror finishing method for cold rolling rollers is proposed. The whole process of the surface finishing can be divided into two phases: electrochemical polishing and mechanical grinding. An anodic film is formed exception for anodic dissolution during ECP. A small amount of the anodic film and metal material are removed by abrasive paper in mechanical grinding. Activated metal surface is exposed again and dissolved in electrochemical reaction after mechanical grinding. Residual of anodic film protects rollers. It is a cyclic process of mirror finishing. Experimental results showed that a mirror finishing surface of up to Ra0.02-0.05μm can be obtained by using this method and that it is effective and efficient.
