Professional stone saw for tilted cuts designed to work slabs "face down", it allows to perform perfect 45 degree cutting even on uncalibrated slabs. No width limitation of the slab to process; even the most narrow strips can be machined thanks to the special pneumatic pistons blocking the stone. The maximum cutting precision is guaranteed by the head travel on linear guides fitted with recirculating ball slides and by the position of the blade cutting from bottom upwards.
