Hub and machining process capable of improving adhesive force of film of hub

Abstract

The invention belongs to the technical field of hub machining, and particularly relates to a hub and a machining process capable of improving adhesive force of a film of the hub. The machining processcomprises the following steps that firstly, hub forming and preliminary machining are achieved; secondly, the surface of the hub is treated, the surface of the hub is subjected to chemical film forming, and the hub is subjected to standing curing; thirdly, a protection film is sprayed to the surface of the hub, then color spraying is carried out to form the film, and the film on the surface of the hub is subjected to standing curing; fourthly, the surface of the hub is subjected to finish turning, surface brightening and extrusion forming, and then high-temperature microwave washing and tankliquor cleaning are carried out; and fifthly, finally the surface of the hub is subjected to lacquer varnish spraying, then standing curing is carried out, and the finished hub is obtained.
