Polishing method
Although there are many methods for metal surface polishing, there are only three methods that occupy a large market share and are used more in industrial production: mechanical polishing, chemical polishing and electrochemical polishing. Because these three methods have been continuously improved, improved and perfected after long-term use, the methods and processes can be suitable for polishing under different conditions and requirements, and can ensure relatively high production efficiency, low production costs and good economic benefits while ensuring product quality. . Some of the remaining polishing methods belong to the category of these three methods or are derived from these methods, and some are polishing methods that can only be applied to special materials or special processing. These methods may be difficult to master, complex equipment, High cost etc.
The mechanical polishing method is to plastically deform the surface of the material by cutting and grinding, and to press down the convex part of the polished surface of the material to fill the concave part and make the surface roughness decrease and become smooth, so as to improve the surface roughness of the product and make the product bright Beautiful or prepare for subsequent surface addition II (electroplating, chemical plating, finishing). At present, most of the mechanical polishing methods still use the original mechanical wheel polishing, belt polishing and other relatively primitive and old methods, especially in many labor-intensive electroplating industries. Depending on the control of the polishing quality, it can process various small workpieces with simple shapes.
