Abstract

The invention relates to a machining process for shaft parts. The machining process comprises the following steps that 1, CNC machining is conducted, specifically, raw materials are machined into blank pieces through a numerical control machine tool; 2, deburring is conducted, specifically, the blank pieces are polished and deburred through a grinding machine; 3, rough grinding is conducted, specifically, rough grinding is conducted on the blanks through a grinder; 4, fine grinding is conducted, specifically, fine grinding is carried out on the blank pieces through the grinder; 5, electroplating is conducted, specifically, nickel plating is conducted on the blank pieces obtained after fine grinding through a nickel plating pool; 6, polishing is conducted, specifically, the electroplated blank pieces are ground and polished through polishing equipment to be machined into workpieces; 7, degreasing is conducted, specifically, after polishing is completed, the workpieces are cleaned and degreased, and drying is conducted after degreasing; 8, inspection is conducted, specifically, the roughness and the circle run-out degree of the degreased and dried workpieces are inspected; 9, correction is conducted, specifically, pressing correction is conducted on the workpieces with the circle run-out degree not reaching the standard; and 10, packaging is conducted, specifically, the qualified workpieces are packaged and conveyed. The machining process has the effect of improving the corrosion resistance of the workpiece surfaces.

Description

technical field [0001] The present application relates to the field of processing shaft parts, in particular to a processing technology for shaft parts and polishing equipment used in the technology. Background technique [0002] Polishing refers to the use of mechanical, chemical or electrochemical action to reduce the surface roughness of the workpiece to obtain a bright and smooth surface. [0003] The existing Chinese invention patent with publication number CN105081941A discloses a mechanical polishing process for the inner wall of a stainless steel storage tank, which includes steps such as rough polishing, fine polishing, fine polishing and polishing detection. Through three times of polishing, the surface of the workpiece becomes bright and smooth. [0004] With regard to the related technologies mentioned above, the inventor believes that the existing polishing process directly polishes the surface of the product, and the oxide film on the surface of the workpiece ...
