[0045] First, start the drive motor 6 and the power motor 11. Then the drive motor 6 drives the grinding disc 5 to rotate through the mounting shaft 4. At the same time, the power motor 11 drives the threaded rod 7 to rotate and cooperates with the mounting part 9 to drive the grinding disc 5 to adjust the grinding range by the movable seat 3. When the movable seat 3 moves and drives the control switch 10 to contact the support seat 8 or the limit beam 12, the power motor 11 is controlled to start to rotate in the opposite direction to turn the moving direction of the grinding disc 5. When the control motor 34 drives the transmission crankshaft 33 to rotate and slides from the arc groove of the transmission part 31 to the straight groove of the transmission part 31, the mounting seat 13 drives multiple sets of positioning chucks 18 to move the position so that the stator core in the working area is disengaged from the top 36. After that, the mounting seat 13 contacts the starting switch 30 to control the servo motor 29 to start, and then the servo motor 29 drives the worm 27 to rotate and engage with the worm gear 28. The rotating seat 16 on the hollow shaft 15 drives the multiple sets of positioning chucks 18 to rotate. After rotating 90 degrees, the servo motor 29 stops rotating. During this process, the driven bevel gear 23 of the original working area is disengaged from the active bevel gear 22, and the driven bevel gear 23 newly rotated to the working area is re-engaged with the active bevel gear 22. Then the mounting seat 13 drives the stator core on the positioning chuck 18 to move and cooperate with the top 36. When the stator core contacts the top 36, the transmission crankshaft 33 slides from the straight groove of the transmission member 31 to the arc groove of the transmission member 31. At this time, the mounting seat 13 drives multiple groups of positioning chucks 18 to lock the working position. At the same time, the mounting seat 13 contacts the contact switch 25 to control the working motor 24 to start. After that, the working motor 24 drives the active bevel gear 22 to rotate through the transmission shaft 21, and then the active bevel gear 22 is engaged with the driven bevel gear 23 at the working area end, and the stator core on the positioning chuck 18 is driven by the support shaft 17 to rotate, and then it can be polished by the polishing disc 5.

[0046] The above is only a preferred embodiment of the present invention.
