[0035] A specific application of this embodiment is as follows: first, when the brake disc 74 needs to be polished, the movable door 4 is opened, and then the brake disc 74 is fixed on the main shaft 72. The movable door 4 is closed to prevent dust from flying out during polishing. When polishing begins, the motor 71 is started, and the main shaft 72 rotates clockwise. When the main shaft 72 rotates clockwise, the rotating shaft 76 driven by the first belt 78 and the main shaft 72 rotates clockwise. When the rotating shaft 76 rotates clockwise, the gear 79 on the rotating shaft 76 and the rack 711 in the rack groove 710 engage and move, so that the rack 711 moves horizontally to the right in the rack groove 710. At this time, the gear 79 on the rotating shaft 76 and the rack 711 in the rack groove 710 engage and move, so that the rack 711 moves horizontally to the right in the rack groove 710. The grinding block 714 fixed in the connecting frame 712 through the limit block 717 moves horizontally. Since there are two grinding blocks 714, when the grinding block 714 moves to the middle of the brake disc 74, both sides of the brake disc 74 will be ground simultaneously. When the grinding is completed, the main shaft 72 rotates counterclockwise. When the main shaft 72 rotates counterclockwise, the rotating shaft 76 driven by the first belt 78 and the main shaft 72 rotates counterclockwise. When the rotating shaft 76 rotates counterclockwise, the gear 79 on the rotating shaft 76 and the rack 711 in the rack groove 710 engage and move, causing the rack 711 to move horizontally to the left in the rack groove 710.

[0036] During the grinding process, the brake disc 74 is continuously ground by the grinding block 714 and generates heat. At this time, the brake disc 74 needs to be cooled to prevent damage to the brake disc 74. When the main shaft 72 rotates clockwise, the rotating shaft 81 driven by the second belt 85 and the main shaft 72 rotates clockwise. When the rotating shaft 81 rotates clockwise, the semi-circular disc 86 in the water tank 82 rotates clockwise. When the semi-circular disc 86 rotates clockwise, the water outlet 88 is indirectly opened, and the coolant in the water tank 82 pours down and flows to the brake disc 74 being ground. On the top, the brake disc 74 is cooled. Due to gravity, the coolant will flow into the waste water tank 89 on the bottom plate 1. The waste water tank 89 discharges the used coolant into the waste water tank 810 through the waste water outlet 811. When the grinding is completed, the main shaft 72 rotates counterclockwise. When the main shaft 72 rotates counterclockwise, the rotating shaft 81 driven by the second belt 85 and the main shaft 72 rotates counterclockwise. When the rotating shaft 81 rotates counterclockwise, its semi-circular disc 86 in the water tank 82 rotates counterclockwise. When the semi-circular disc 86 rotates counterclockwise, the water outlet 88 is closed.
