The saw cuts the slab as the spindle holding beam advances at a right-angle to the conveyor belt. The beam travels at a perfect right angle on guides enclosed in an oil bath and protected by a labyrinth seal casing. Beam motion is controlled by a variable speed motor and two ball screw assemblies coupled to ball nuts mounted to the two supporting frames of the beam.

A shaft coupled to the angle reduction units ensures the ball screw assemblies are synchronised. A mobile aligner for squaring up the strips before cutting is installed at the front end of the marble cutting machine opposite the spindle-holding beam.

The aligner travels on roller bearings and is driven by pneumatic cylinders and two rack-pinion couplings which ensure synchronised movement. This system guarantees an almost perfect geometry of rightangled workpieces.
