Abstract

The invention discloses a surface polishing process for a metal part. The surface polishing process is specifically carried out according to the following steps that firstly, the surface of the metalpart is subjected to high pressure washing, is placed in cleaning liquid for degreasing treatment, is dried and is then ultrasonically cleaned; the metal part is then placed into a polishing solutionfor polishing, and pickling, neutralization, rinsing and drying are carried out; and finally, metal anti-rust wax is applied to the surface of the metal part. According to the surface polishing process, an environment-friendly polishing process is adopted, the operation is simple, running cost is low, safety and environmental protection are achieved, the micro-geometry shape of the metal surface can be can improved after polishing, the micro-roughness of the metal surface is reduced, and the gloss of the metal surface is improved.

Description

technical field [0001] The invention belongs to the technical field of metal polishing, and in particular relates to a surface polishing process of a metal piece. Background technique [0002] Metal polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of metal workpieces to obtain a bright and smooth surface. Metal polishing is the modification of the surface of metal workpieces using polishing tools and abrasive particles or other polishing media. [0003] Chemical polishing is to achieve a bright and smooth metal surface through regular dissolution. During the chemical polishing process, the passivation oxide film and the oxide film are continuously dissolved on the surface of the metal parts, and the former is stronger than the latter. Due to the microcosmic inconsistency of the surface of the part, the microscopic convex part on the surface dissolves preferentially, and the dissolution rate is greater than that o...
