System for processing of flat and bevelled switch panel components and mounting plates up to a size of 1500 x 2400 mm as well as non dismountable enclosures up to a size of 2200 x 1600. Powered depth gauge with end-switch at machining position for enclosures, for ergonomic positioning of heavy enclosures. Fully pneumatic enclosure fixation. Fixation of flat workpieces by means of 6 fluidic muscles on lower side (individually switchable for avoidance of keepout areas for clamping) and mechanical quick clamps on upper side. Conversion between the processing of flat material and unmountable enclosures occurs fully automatic. Unconditional option for simultaneous machining of several workpieces like mountingplates and/or unmountable enclosures.
