M945 Bridge Saw
This automatic cycle machine, that has been designed for the production of building elements and paving stones, has been realized in the versions
marble or granite for 2000 and for 1600 mm disc diameter.

Bridge:
The bridge is made up of a seasoned cast iron monoblock beam. The control panel and all the electrical and electronic equipments are jointed to the bridge which has refaced bearing wheels and slides on hardened steel interchangeable bars housed in cast iron bodies giving the maximum stability to all the assembly. The bridge traverse on the guides takes place with gears on high precision racks. Everything is protected against water splash by proper gaurds fixed to the bridge. The displacement can be checked through a visual system with metric / inch rule and on the display of the electronic programmer.
Bridge control unit:
The traverse of the bridge is carried out automatically by means of a self braking speed variating gearmotor or manually by means of a handwheel on side of the control board. During the cutting operation, the bridge is kept in position by a double electromagnetic locking device.
Carriage:
The accurately machined cast iron carriage determines the cutting speed. It slides with prismatic sliding blocks in oil bath on interchangeable slide tracks housed inside the bridge. The carriage control group allows progressive speed variation and high power transmissions by means of a special device, maintaining always a smooth a vibrationless movement. Inside the carriage, there is the cast iron vertical slide which allows the automatic rise and descent of the spindle by means of a gearmotor, screw and bronze lead nut. The slide moves on refaced and adjustable bronze screw nuts and is controlled by the equipment for the incremental step cuts.
Spindle:
"DIGITAL" version:
For vertical and inclined cuts from 0° to 90° in a single cut, the spindle is fixed to the vertical slide and rotates manually by means of a handwheel. A special two-speed 24 HP direct motor provided with special protection is fixed to the tilting group. the tilting group and the slide attachment plate are cast iron made and the rotation takes place by means of a special helicoidal gear and worm screw controlled by a handwheel.
"UNIVERSAL" version:
The spindle, for vertical and inclined cuts from 0° to 90° both ia a single cut and several incremental cuts, rotates by means of a handwheel and runs on a slide and a counterslide both of cast iron applied to the tilting group. The movement of the counterslide on the slide takes place by means of a speed reducer, screw and nut screw supported by a proper thrust bearing on adjustable guides. A two-speed 24 HP motor with special protection is fixed to the counterslide.
The "DIGITAL" machine is supplied in its standard version with no. 1 cast-iron worktable, manually rotating and lockable at 0°, 45°, 90°, 135°.
