Abstract

The invention discloses a part surface treatment method, relates to the technical field of part surface treatment, and aims to solve the problems that the roughness of the surface of an impeller cannot be quickly reduced, the labor intensity is high and the quality of the impeller is low in the prior art. The part surface treatment method comprises the steps of performing first electromagnetic polishing treatment on the surface of a part; sequentially performing sand blasting treatment and grinding treatment on the part obtained after first electromagnetic polishing treatment to obtain a ground part, wherein the surface roughness of the ground part is consistent; and performing second electromagnetic polishing treatment on the ground part to obtain a treated part, wherein the surface roughness of the treated part is smaller than that of the ground part.

Description

technical field [0001] The invention relates to the technical field of part surface treatment, in particular to a part surface treatment method. Background technique [0002] The impellers manufactured by additive manufacturing technology are usually aluminum alloy impellers with rough surfaces. In the prior art, a fitter is usually used to manually polish the impeller to reduce the surface roughness of the aluminum alloy impeller. [0003] Because the front ends of the large blades and small blades in the impeller parts are relatively sharp and small in size, the impeller is easily damaged when the fitter handles it. In addition, due to the large area in the middle of the large and small blades, the fitter has a large grinding workload, and there is a problem of uneven removal during grinding, which easily leads to failure of the dynamic balance of the impeller. Contents of the invention [0004] The purpose of the present invention is to provide a part surface treatmen...
