The axis of the ball screw 36 is at the same level as the center of the cutter head 22 and the machining end 231 of the cutter 23. When the cutter 23 is in contact with the workpiece, the reaction force is pushed back along the axial direction of the ball screw 36, causing the ball screw 36 to push the knife. Both the force of the tower 20 and the reaction force of the cutter 23 act on the axial direction of the ball screw 36. By the cushioning of the elastic timing belt 39, the ball screw 36 can also smoothly push the turret 20 so that the cutter 23 is paired. The workpiece feed speed is more consistent and stable, and the surface of the workpiece can be made smoother and smoother.
