1. Material problem. Stainless steel is a type of steel formed by smelting and depositing iron ore, metal element materials (different materials add elements with different compositions and proportions), and it also undergoes several processes such as cold rolling or hot rolling. During these processes, some impurities may be accidentally added, and these impurities are very small and integrated with the steel. They cannot be seen from the surface. After grinding and polishing, these impurities appear, forming a very Obvious pitting is usually caused by 2B materials, which are matte materials. After grinding, the brighter the surface, the more obvious the pitting.) There is no way to remove the pitting caused by this material problem.
2. An unqualified polishing wheel is used. If there is a problem with the polishing wheel, the problem will not only be pitting, but also grinding heads. [There are too many polishing wheels on the machine. Find out the problem. Wherever, the polishing master needs to check and replace one by one. If the quality of the polishing wheel is not up to par, then all of them need to be replaced! There are also unbalanced polishing wheels, which cause uneven stress on the material, and these problems will also occur!
