[0031] When using a convenient flat milling machine to process the workpiece;

[0032] Workpiece clamping and positioning stage:

[0033] The workpiece to be processed is placed between the left and right clamping blocks 305, and the first motor 301 is started. The first motor 301 drives the stud 302 to rotate, and the stud 302 drives the two threaded blocks 303 to move. The threaded blocks 303 drive the vertical plate 304 to slide through the connecting rod, and the vertical plate 304 drives the chuck 305 to move. Both chucks 305 are tightly fitted with the outer wall of the workpiece to clamp and position the workpiece;

[0034] Workpiece processing stage:

[0035] The third motor 11 drives the second sleeve 9 to rotate, and then drives the fine grinding disc 12 to rotate, the first cylinder 7 drives the back plate 8 to descend, and then the fine grinding disc 12 moves downward to contact the workpiece for fine grinding of the workpiece, and the second cylinder 10 drives the slider 5 to slide, and then the fine grinding disc 12 moves left and right, and the fine grinding disc 12 fine grinds the left and right directions of the upper surface of the workpiece. When fine grinding of other surfaces of the workpiece is required, the first cylinder 7 controls the fine grinding disc 12 to rise, and starts the second motor 306. The second motor 306 drives the left chuck 305 to rotate, and then drives the workpiece to rotate, so that the surface of the workpiece that has not been finely ground faces the fine grinding disc 12, and the fine grinding disc 12 fine grinds the workpiece.

[0036] Fine grinding disc replacement stage:

[0037] When the fine grinding sheet needs to be replaced, the support rod 405 is held by hand and pulled, and the support rod 405 drives the slide rod 403 to move, and the slide rod 403 slides inside the first sleeve 402 and compresses the spring 404. The end of the slide rod 403 is separated from the slot provided in the cylinder 406 and is no longer clamped and fixed to the cylinder 406. The fine grinding sheet 12 and the cylinder 406 are removed, and the fine grinding sheet 12 to be replaced is replaced. The replaced cylinder 406 is inserted into the interior of the second sleeve 9, and the support rod 405 is released. The spring 404 drives the slide rod 403 to slide in the opposite direction under the elastic action, and the end of the slide rod 403 is inserted into the slot provided in the cylinder 406, and then the cylinder 405 is clamped and fixed to the interior of the second sleeve 9, completing the replacement of the fine grinding sheet 12.
