Vacuum suction cups are used to carry marble slabs from the processing workshop to transport vehicles, construction sites or warehouses, and use uniform suction to avoid scratches and damage to the slabs. They can also fix the marble during processing, ensure its stability during cutting, grinding, carving and other steps, and ensure processing accuracy. When installing marble, they can assist construction personnel in accurately positioning the slabs on the wall, ground and other locations, thereby improving installation efficiency and quality, reducing splicing errors, and ensuring the flatness and aesthetics of the installation.
