During the processing of marble 20, due to the friction between the grinding disc 8 and the surface of marble 20, heat will be generated and a large amount of dust will escape. function and remove dust. During processing, water is sprayed from above the marble 20 to scour the surface of the workpiece. It has a very good promoting effect on reducing the wear of the grinding disc 8, reducing the processing noise, and improving the processing efficiency. Since some marble 20 fine pieces and dust will be produced during the processing, they are scattered on the marble 20 surface, which will have a certain impact on the processing quality of the marble 20 surface, and the fine pieces on the marble 20 surface can be washed away under the washing of water At the same time, a filter screen is set in the water tank 28 to intercept fine pieces and dust, thereby improving the processing quality of the workpiece surface.
