Abstract

The invention discloses an automobile part surface machining process. The automobile part surface machining process comprises the steps of oil removal, surface rust removal and activation, phosphorization, saponification, surface finishing and oil removal. According to the process, through surface oil removal, rust removal and phosphorization treatment, surface finishing is increased, protection is provided for automobile metal parts, and metal is prevented from being corroded to a certain degree; and meanwhile, the process is used for bottoming before painting, and therefore the adhesive force and the anti-corrosion capacity of a paint film layer are improved, the surface performance of the automobile parts is effectively improved, and the service life of the automobile parts is improved.
