For the workpiece 30 having a diagonal length of 2 L, in order to make the central axis of the workpiece 30 on the same line as the central axes of the first rotating rod 128 and the second rotating rod 134, the workpiece 30 needs a rising distance (HL), that is, 4 cm. And a series of scales on the measuring rod 1426 decreases from the initial scale to the direction away from the first surface 1421, and the series of scales indicate that the workpieces 30 of different sizes are placed, in order to make the center axis of the workpiece 30 and the first The central axes of the rotating rod 128 and the second rotating rod 134 are on the same line Above, the workpiece 30 needs to be raised or lowered. Of course, the initial scale may also be disposed at a position where the measuring rod 1426 is in contact with the first surface 1421.

It can be understood that if the scale displayed by the position where the measuring rod 1426 and the fifth surface 1481 intersect after the workpiece 30 is placed is a negative value, it indicates that the workpiece 30 needs to be lowered by the absolute value of the negative value to make the workpiece 30 The central axis is on the same line as the central axes of the first rotating rod 128 and the second rotating rod 134.

The driver 1461 is precisely driven to the carrier unit 142 such that the carrier unit 142 and the plurality of workpieces 30 therein are raised or lowered by the absolute value of the scale. In this embodiment, the load bearing unit 142 and the plurality of workpieces 30 therein are raised by 3.8 cm. The fourth step is to control the driver 1461 by the controller 1462 to separate the load bearing unit 142 from the workpiece 30, and remove the The carrying unit 142 removes the lifting device 144 and rounds the workpiece 30 by the round grinding wheel 15 to obtain a round finished workpiece.
