Mirror polishing directly depends on the level of finish. Mirror polishing is divided into mechanical mirror polishing and chemical solution mirror polishing. Now let's talk about the mirror polishing process.
Mechanical mirror polishing refers to the process of polishing (coarse grinding, fine grinding) and polishing (WENDT three-step polishing) on metal materials to achieve a flat, bright mirror like surface.
1、 Grinding process
The purpose of grinding is to obtain a flat and smooth grinding surface. At this time, there are still very fine and uniform wear marks on the grinding surface. Grinding is divided into rough grinding and fine grinding.
1. Rough grinding Rough grinding is to correct the rough surface and irregular shape.
2. After fine grinding and rough grinding, there are still deep wear marks on the metal surface, which need to be removed in fine grinding to prepare for polishing.
2、 Mirror polishing process
The polishing process is to obtain a bright mirror like surface processing process. Most of them use polishing wheels to polish the extremely small unevenness on the surface of the parts after repeated polishing, which is generally used for coating surface modification.
Polishing is a process of coating surface or part surface, which aims to eliminate the fine grinding marks left on the surface after the polishing process. The ideal polished surface should be a mirror like surface that is flat, bright, traceless, embossed, free of pits and metal disturbing layers. The change of grinding surface after grinding and polishing by a plane grinder.
