ABSTRACT:
A machine is provided which automatically cuts and polishes disks of marble and finishes the edges of those disks. A marble cutting saw blade and a marble polishing wheel are disposed on a track located in spaced separation from a turntable. The turntable includes a central supporting pedestal and peripheral spacers which may be selectively located on a support to bear against the underside of a marble slab just within the diameter of a round disk which is to be cut therefrom. The sawing and polishing assemblies are mounted on separate carriages which move longitudinally along the track. The sawing and cutting assemblies can be adjusted vertically by means of separate, power driven drives. The speed of rotation of the turntable can be altered. An arbor is preferably located on the track between the two carriages to project toward the turntable. The arbor stabilizes the marble slab as it rotates with the turntable. Both the sawing and polishing assemblies are flushed with water to prevent chipping, suppress dust and increase the speed of cutting.
