Holes in a grid of 120 mm for vacuum connection, easily removable via a magnetic device (patented system). The entire surface is grooved at a distance of 20 mm so that the workpieces can be clamped using rubber seals, MODULSET or suction cups. Automatically retractable reference stops that ensure accurate positioning of the workpieces to be machined. Moving gantry It is a gantry structure made of cold-rolled steel in a box construction, consisting of rectangular sections. The working units are installed on the gantry. Working unit consisting of a drilling head with vertical spindles, horizontal spindles, an integrated grooving and sawing unit and an SCM electrospindle with a quick-change tool system of type HSK63F. Travel of the gantry and aggregate carrier The movement in the X, Y and Z axis takes place on linear prismatic recirculating ball guides by means of pre-tensioned ball screws. The movement transmission of the X and Y axes (moving column and carriage) takes place via a reduction gearbox with rack and pinion drive. The movement of the aggregate carrier in the Z direction takes place via pre-tensioned ball screws. Positioning of the working units and control of the machine functions takes place via "Brushless" three-phase servo motors and digital control units. CONTROL The control unit consists of a numerical control. Fsdpfoz Iyvpox Al Sepn
