[0022] The steering screw sensor 6 transmits the inner diameter information of the steering screw matched with the input shaft 4 to the controller 1, the controller 1 controls the first driving member to drive the first support plate 3 to reciprocate relative to the polishing assembly, so that the polishing assembly polishes the outer diameter of the input shaft 4, and the outer diameter of the input shaft 4 reaches the matching standard with the steering screw. The steering screw sensor 6 collects the inner diameter value M1 of the steering screw, and the controller 1 calculates the target value G1=M1-△M of the outer diameter of the input shaft 4, wherein △M is the difference between the inner diameter of the steering screw and the outer diameter of the input shaft 4.
