[0033] When the magnetic sheet is being polished, the threaded rod 11 is driven to rotate by the second motor 10, and the rotation of the threaded rod 11 drives the movable plate 4 to approach the side of the polishing chamber 3, so that the transparent protective shell 5 is connected to the polishing chamber 3, and the polishing roller 7 can enter the polishing chamber 3 to polish the magnetic sheet. At the same time, it can also effectively block the waste chips, debris, and sparks generated during the polishing process.
