I plant the workpiece shown in Figure 1, the original method of the car shown in Figure 2, the removal is difficult. Later we switched to the screw 3 (Fig. 3) with a three-jaw chuck and padded the washer 2 between the workpiece 1 and the three-jaw chuck 4. When the workpiece 1 is lowered, the three-jaw chuck 4 is released, and the washer 2 is not eaten, and the workpiece 1 can be easily removed.
