Three grinding wheels can be installed at the same time by using different grinding wheel head 503 parts, and the three grinding wheels have different grain sizes, corresponding to 400#, 800#, 3000# from rough grinding, fine grinding to polishing, and then the position of the workpiece 409 is adjusted horizontally and vertically;

[0054] The first screw rod 203 is rotated by the rotation of the first driving motor 202, so that the first slide 204 on the first screw rod 203 is adjusted and moved horizontally, so that the first slide 204 drives the horizontal moving slide 206 to move left and right on the first slide rail 205 to adjust the position of the cutting blade. At the same time, the second driving motor 302 is controlled to rotate to drive the second screw rod 303 to rotate, so that the second screw rod 303 can easily drive the longitudinal moving seat 304 to rotate while rotating, so that the cutting blade can be adjusted in the longitudinal direction, so as to grind the double edges of the cutting blade.

[0055] Then, the first servo motor 502 rotates to drive the grinding wheel head 503 to rotate, so that the grinding wheel head 503 can grind the double edges of the cutting blade.

[0056] Finally, the vacuum cleaner 604 is turned on to allow the top and bottom dust collection shells 602 to absorb the grinding dust, and the dust absorbed by the dust collection shells 602 is transported to the vacuum cleaner 604 through the dust collection tube 603 for absorption and cleaning.
