1. Light yellow (feather cloth)· Polishing A polishing method by placing it on a polishing cloth of various materials and grain sizes to make the metal surface rotate at high speed. For mirror polishing, hairline finishing, metal deburring, metal surface treatment, hair surface treatment before electroplating and polishing after electroplating can improve the value of the product. Although grinding the stone in the same application, polishing with a polishing cloth can effectively polish the surface without changing the shape of the object to be polished by exploiting the elasticity of the wing cloth.
2. Barrel polishing (dumpling, rotary polishing) A polishing method in which smaller items are placed in a rotating container along with grinding AIDS, such as abrasive agents such as silica sand. It is also known as tumble/spin polishing. As a feature of roller polishing, a large number of goods can be removed in one process, rough, medium, and polished.
3. Sandblasting (blowing)· Processing polishing method This is a method of high-speed spraying solid surface metal, mineral or plant shooting material (abrasive) on the treated surface by centrifugal projection sandblasting machine and so on and finishing the surface. Surface cleaning such as steel plate scaling, deburring, decorative coating, etc., and used as surface pretreatment for electroplating, alumina film treatment, coating, coating treatment, etc. Harder projection materials than workpieces such as steel pellets subjected to shot peening are blown into the metal surface during blasting, the result is that the surface becomes smoother with the metal surface, the hardening is slower, and the fatigue of the metal is significantly what you can do.
4. Electropolishing method (chemical polishing method) When the anode current passes through the metal surface in a specific solution, the product surface dissolves and the metal adheres to the cathode to form a smooth, glossy surface. It is used for iron/aluminum underlining treatment and stainless steel surface treatment.
