[0035] Specifically, the workpiece is placed on the upper end of the lower turntable 2, and the grinding disc 32 clamps the workpiece toward the center. The workpiece is driven to rotate during the rotation of the grinding disc 32. The distance measuring sensor 4 detects the sliding distance of the grinding disc 32, keeps the three grinding discs 32 at the same distance from the center of the lower turntable 2, and thus keeps the workpiece round.

[0045] It should be understood that by providing the downward pressure spring 54, the downward pressure spring 54 maintains pressure on the workpiece, so that the workpiece can move in the horizontal direction while being subjected to the downward pressure.

[0046] Furthermore, a turnbuckle 541 is hingedly connected to the mounting plane 11 , and the lower compression spring 54 is connected to one end of the turnbuckle 541 away from the mounting plane 11 .
