  • 2022-08-23 17:40:17

Mirror polishing is a polishing process that makes the surface of the product show a mirror effect. It is mainly used to reduce the surface roughness of the workpiece. When selecting a polishing process for a metal workpiece, different methods can be selected according to different needs. This process is usually used in elevators. Cars, aerospace equipment accessories, molds, auto parts, medical machinery, decorations, etc., products in this category require a bright and clean appearance. The ideal mirror polishing effect is that the polished surface has no traces, bright, flat, no relief, no metal disturbance layer, and no pits. Mirror processing means that the processed surface can reflect the image like a mirror. This level has reached a very good surface quality of the workpiece. Mirror processing can not only create a high "look" for the product, but also reduce the notch effect and prolong the fatigue of the workpiece. Life; it is of great significance in many assembly and sealing structures.

Mirror polishing requires many times of grinding and polishing, and the surface roughness of the product workpiece must reach grade 12 or above. The mirror polishing process is to use polishing sandpapers of different roughness to polish the surface of the workpiece step by step, and use flexible polishing tools and abrasive particles or other polishing media to modify the surface of the workpiece. We will introduce several common methods of mirror polishing in the next article, so stay tuned.
