Furthermore, a control module 700 is provided on the sander, for example, as shown in fig. 1 and fig. 3, the control module 700 can be used to control the sander to start or stop working, and can also be used to control the operation of the first driving mechanism 410, the second driving mechanism 420, the third driving mechanism 430 and the fourth driving mechanism 440.

Through the utility model discloses polisher, through so setting, following beneficial effect has at least: the workpiece 600 to be processed is fixed on the fixing table 312, the workpiece 600 to be processed is conveyed to the cutting unit 500 for cutting by the pressing block 313 after being pressed by the pressing block, and the workpiece 600 to be processed is conveyed to the polishing unit 200 for polishing by the transmission assembly after being cut. The grinding wheel 220 at the grinding unit 200 grinds the processed workpiece 600, the first driving mechanism 410 drives the grinding wheel 220 to slide up and down, the processing surface of the grinding wheel 220 can slide up and down, the processing surface can uniformly grind the processed workpiece 600, the abrasion degree of the grinding wheel 220 can be uniformly spread on the side surface of the grinding wheel 220, and the situation that the whole grinding wheel 220 cannot be used due to the fact that a certain part of the grinding wheel 220 is abraded too heavily and other parts are not abraded is avoided. Meanwhile, the second driving mechanism 420 can also enable the grinding wheel 220 to move forward to be close to the processed workpiece 600 according to the abrasion condition of the grinding wheel 220, so that the abrasion condition of the grinding wheel 220 can be compensated for, and the original grinding precision can be maintained.

Meanwhile, the third driving mechanism 430 may push the fixed stage 312 forward to change the machining size of the workpiece 600 to be machined. The fourth driving mechanism 440 can drive the cutting unit 500 to move up and down so as to accommodate the workpieces 600 to be processed with different sizes and thicknesses. The cooling assembly is used for cooling the workpiece 600 to be processed. The cooling assembly may be cooled by water, and cool water may be used to cool the cutting unit 500 and the grinding unit 200, and dust and debris caused by cutting and grinding may be reduced.
