Pneumatic material advance for stoneStone saw with pneumatic material advance
Above: This special support has been carefully designed to support large, hard to move, pieces of marble. As the saw advances, two steel bars protrude to support the cut piece and prevent its fall. This support also has a special mechanical device that allows you to advance the piece from time to time, placing it at the exact spot to cut.

Cutting stone arches Cutting stone arches Device for cutting stone arches
Above: Feed device for automatic cutting of arcs. This allow continuous cutting of the material with the use of templates available in various arc angles. The hydraulic motor will initiate a pinion that engages in a rack placed on a template, allowing the saw to follow the cut automatically without the guidance of the operator.

Cutting stone column Diamond wires for stone saw
Above: You can add an extra column to the set 400 in order to fix the workpiece. Note that this limits the saw's ability to work from both sides. Above right: Diamond wires, available in 6mm, 8mm and 10mm widths (2400 mm in length) for the STM 300 and 8mm, 10mm and 11.5 mm (3600 mm in length) for the STM 400.
