s2, flattening: the third cylinder (402) extends out, the pressing plate (403) presses the workpiece downwards, the workpiece is guaranteed to be processed in a horizontal state, the flatness of a polishing plane is guaranteed, and the third cylinder (402) is retracted after flattening;
s3, station switching: the pressing plate (403) is separated from the position right above the workpiece by the rotation of the motor B (501), and the polishing disc (301) is positioned right above the workpiece; the second cylinder (303) moves downwards and the motor A (304) rotates, so that the polishing disc (301) is in contact with the workpiece, and the upper surface of the workpiece is polished;
s4, water spraying and cooling: after the polishing disc (301) contacts a workpiece, the guide rod (6041) moves upwards, the first baffle plate (6043) pushes the cross rod (6053) upwards, the second baffle plate (6051) leaves the notch (6032), the water outlet (6031) starts to discharge water, and the water is discharged from the notch (606) to the plane between the polishing disc (301) and the workpiece, so that the cooling of the polishing disc (301) is realized; after polishing, the polishing disc (301) leaves the workpiece, the polishing disc (301) moves downwards under the action of gravity and the tension of the first spring (6042), the first baffle (6043) is away from the cross rod (6053), the second baffle (6051) moves downwards under the action of the tension of the second spring (6052) and blocks the gap (6032), and water does not flow out due to the action of atmospheric pressure.
