No matter how big or small hardware products are, they are exquisite handicrafts carved out step by step. How to make a group of metals have a shape? How to make a dull metal shine? How to make a rough metal smooth? Grinding and polishing is the most inseparable process to become a smooth and shiny product.
There are seven steps in the process of metal formation: mold opening, die-casting, grinding machine smoothing, polishing, painting, electroplating, and assembly, among which grinding machine smoothing and polishing also play an important role
1. Grinder smoothing
After the product has gone through the previous two processes, it has a basic shape, and the metal is also solidified, but the surface has many sharp angles, which makes it feel bad to the touch. At the same time, the surface of the metal is dull, which affects the appearance. At this time, the smoothing machine is used. The fast-rotating abrasive belt removes the residual parting line of the casting, and then it is smoothed by the grinder for half an hour to remove the sharp corners of the metal surface, so that the metal feels smooth and does not pierce hands.
2. Polishing
After the metal has been smoothed by the grinder, it will be polished in the next step. Polishing is to use a fast-rotating hemp wheel or cloth wheel to put the product on the hemp wheel or cloth wheel to grind and polish the surface of the product; after the grinding and polishing process, all technicians are required to check whether it is qualified, and the unqualified ones will be reworked.
