Under the action of the power member 7, the follower 8 slides in the guide groove 2. During this process, the ball 9 rolls in the mounting groove of the follower 8. At the same time, the detection member 12 determines the distance the follower 8 drives the product to move by detecting the position relative to the reference member 13. The above process is maintained until the follower 8 reaches the required position. The external control system stops energizing the follower 8. At this time, the follower 8 loses its magnetism and stops moving. During this process, the power member 7 adsorbs the follower 8, and the external tool processes the product again.
