Polishing is an important step in Sheet Metal Processing. If stainless steel materials want to ensure the appearance of aesthetics, they need to be polished. In the process of polishing, many of us will encounter various problems. Among them, we will encounter the problem of poor polishing performance of sheet metal processing. How to solve it? Reasons for poor polishing performance in sheet metal processing: 1: Material. Although sheet metal processing is made of stainless steel, the difference in metal content will also lead to different hardness. If the hardness of the original material is too low, it is not suitable for polishing, so it can only be simply polished. 2: Affected by its own defects. There are some defects on the surface of sheet metal processed stainless steel that cannot be polished, such as trachoma, pitting, etc. This defect can only be filled by other means. 3: Even deep-drawn sheet metal processed stainless steel products will have some adverse effects, but the relationship between the amount of deformation will also affect its polishing performance.
