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.
