The machine automatically and thickness, optical control, variable speed and other advanced technology, high precision sanding, layout, easy to operate, practical wide range of resins and plastics for achieving the grinding plate and thickness of a low heat, by the cooling effect of water, so that plate in the grinding process, the belt will not be generated due to heat bonding, sanding to achieve a good effect of heat dissipation and reasonable, surface burns, no plastics, etc., is necessary for artificial stone processing industry equipment.
