Vacuum suction cups are mainly used for rough stone slabs to lift them from the stacking place to the processing equipment, to fix the rough stone slabs during cutting, carving and other processing to ensure processing accuracy, and can also be used to turn the rough stone slabs over for double-sided processing or inspection. During the transportation of rough stone slabs, they can be firmly fixed on the transport vehicle or pallet to prevent damage caused by shaking and collision during transportation. When the rough stone slabs are installed on the walls, floors and other locations of the building, the vacuum suction cups can help construction workers accurately locate and install them to ensure the flatness and position accuracy of the installation.
