The diamond blade-holding spindle unit is mounted on a cast-iron trolley running along the rectified guides of the bridge on ball-bearing slides. The movement of the spindle-holding trolley is obtained by means of a geared belt and a reduction gear unit with inverter, which makes it possible to adjust the cutting advancement according to the type and thickness of the material to be processed.
The sliding system is lubricated in an oil bath and protected by stainless steel labyrinth seal covers. The spindle unit has pneumatic vertical exclusion: after cutting has been carried out, the spindle unit raises automatically before reaching the starting position, while securing the following strip positioning.
