the auxiliary claw blank is fixed on the centering bench clamp (51), a first machining device (3) and the centering bench clamp (51) mill a cavity which is one to one with the profile outline of the auxiliary claw blank at a specific machining position, at the moment, the auxiliary claw blank forms a centering A auxiliary claw (511) and a centering B auxiliary claw (512), and then the centering bench clamp (51) performs feeding movement to clamp the end part of the profile on the main shaft box (2);
after milling the profile by the first processing device (3), interacting with a first tool magazine (31), replacing a cutting saw blade to perform cutting work, driving the cut semi-finished profile to a second processing position by a centering bench clamp (51), and starting the second processing device (4) to mill a finished part;
the centering bench clamp (51) drives the finished part to move to the position of the part conveyor (6), the centering bench clamp (51) is turned over to place the finished part above the part conveyor (6), the auxiliary claw A (511) and the auxiliary claw B (512) are loosened, and the finished part falls into the part conveyor (6) to be output to the lathe bed (1).
