Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a grinding and polishing machine for stone. Background Art

[0002] Stone grinding and polishing machines use high-speed rotating grinding discs or wheels, combined with abrasives and polishing fluids, to finely process the stone surface to achieve a smooth and bright effect. They are widely used in the processing of various types of stone such as marble, granite, and artificial stone, and play an important role in stone renovation, maintenance, and crystal surface treatment.

[0003] Reference can be made to an existing document on an artificial quartz stone slab polishing device (CN219767826U). The grinding device and workbench on the frame can move horizontally and vertically respectively, so that all the stone slabs placed on the workbench can be effectively polished. This allows the polishing work to be carried out over a wide range, thus meeting the needs of polishing stones of different sizes.

[0004] During the stone grinding process, a lot of debris and dust will be generated due to the friction between the abrasive and the stone surface. These debris not only include tiny particles of the stone itself, but also contain powder produced by abrasive wear. The flying of these debris and dust will affect the respiratory health of the workers, and the scattering of stone debris will also increase the dirtiness of the working environment. In order to keep the working environment clean and safe, the workers will need to spend time and energy to clean up these debris later. Utility Model Content
