A shell is installed above the base, and a workbench is installed above the support rod; a quartz countertop is arranged on the workbench, and an air pump is installed on the second connecting pipe; a telescopic cylinder is installed in the middle of the upper part of the shell, a threaded sleeve is installed on the screw, and a grinding wheel is installed below the second rotating shaft; dust hoods are arranged on the left and right sides above the grinding wheel, and a second telescopic hose is installed above the third connecting pipe. Through the coordinated use of the dust hood, the second telescopic hose, the vacuum cleaner and the dust box, the dust generated during the grinding process can be absorbed to keep the quartz countertop clean, and at the same time, dust can be prevented from polluting the environment and mechanical equipment. In the technical solution recorded in the Chinese patent, the workbench can be reciprocated forward and backward by the cooperation between the first motor, the first rotating shaft, the gear and the spur rack, and the grinding wheel can be reciprocated left and right by the cooperation between the second motor, the screw rod and the threaded sleeve. That is, in the technical solution recorded in the Chinese patent, the quartz stone table top (quartz stone slab) is only polished by the forward and backward and left and right movements, and the same point cannot be polished in a circular manner, and the circular polishing effect will be better, so it needs to be improved.
