Surface polishing is a method of polishing the surface of stainless steel sheet metal with mechanical or manual abrasive materials. Surface polishing has the effects of polishing, mirror surface, mercerization, sandblasting and so on. The tools and methods used vary depending on the surface effect. Polishing tools are abrasive cloth, abrasive paper, magic wheel, polishing belt, abrasive wheel, etc. During polishing, countless abrasive particles are equivalent to countless high-hardness blades. Cutting is performed on the stainless steel sheet metal processing surface to achieve the purpose of flattening.

       Mirror effect atmosphere pre-polishing and fine polishing. Pre-polishing uses a hard or harder polishing wheel to process the polished stainless steel sheet metal processing surface. It can go out and grind rough traces on the surface. Fine polishing uses softness to further process the pre-polished surface to remove the traces left by the pre-polishing to obtain a bright mirror surface.

       The mercerizing effect is a process of using a brushing wheel mounted on a grinding and polishing machine to process a stainless steel sheet metal processing surface to obtain decorative silky brushing and satin finishing effects.

       Sand blasting effect. Use compressed air flow to spray sand or steel shots, glass shots and other abrasives on the stainless steel sheet metal processing surface, making it appear beautiful and slightly rough sandy surface.

       Surface etching and etching are a mottled and vicissitudes of decorative effect obtained by using chemical acid for corrosion. The specific method is as follows: firstly apply a layer of asphalt on the stainless steel sheet metal processing surface, and then trace the designed texture on the surface of the asphalt, and expose the stainless steel sheet metal to be corroded. Corrosion can be performed below. Depending on the size of the work, corrosion can be selected by immersion in a chemical acid solution and spray solution corrosion. Generally speaking, small works choose immersion corrosion. Chemical acid is extremely corrosive, so you must pay attention to safety protection when performing corrosive operations.

       The surface inlaying process has a long history, and it includes two processes: stone inlay and gold inlay. The coloring and gold inserting process here is also called gold-silver fault. It first traces shadows on the stainless steel sheet metal processing surface, embeds softer stainless steel sheet metal processing materials such as gold and silver wires or gold and silver sheets, and then smoothes them. The effect is very slim and gorgeous.

    Surface forging is also developed from the ancient forging process. It uses different shapes of hammer heads to forge on the surface of stainless steel sheet metal processing, so as to form different shapes of point-like texture, layer by layer, very decorative.
