Metal Surface Polishing

Release time：2025-10-01    Click：41

　　Like all metal finishing, polishing involves the removal of imperfections on the metal surface. Depending on the state and condition of the metal, polishing makes use of different abrasives that may be classified as coated, bonded, or loose media. Coarser or rougher abrasives are used in the primary process to smoothen out the larger and more stubborn deformities. After, finer abrasives are utilized for further polishing.

　　Aside from the condition of the metal, the type of metal also determines which abrasives will be part of the polishing equipment. This is largely dependent on the tensile strength, which measures the maximum load that the material is able to withstand before breakage. Low-tensile strength metals like copper, brass, or aluminum make use of silicon oxide abrasives. On the contrary, high-tensile strength metals like iron and carbon require grey or white aluminum oxides. These abrasives are used in combination with polishing materials like cloth, cotton, rubber, and the like.
