[0014] The present invention will be further explained below in conjunction with the drawings:
[0015] With reference to the attached drawings, the processing method of a chemical centrifugal pump shaft is characterized by the following steps: 1) Drilling the center hole: Use a three-jaw chuck to clamp the outer circle of the blank, and use a center drill to drill the center holes at both ends of the shaft; 2 ). Rough turning: use the movement chuck to top the shaft, reserve 0.2mm machining allowance for each outer circle of the rough turning, and reserve 1mm machining allowance for the length of each step of the rough turning; 3), quenching and tempering treatment; 4), Finish turning: use the movement chuck to top the shaft, finish turning the maximum outer circle of the shaft to the drawing requirements, finishing various threads to the drawing requirements, and finishing the length of each step to the drawing requirements, and chamfer; 5), grinding : Grind the outer circl...
