Abstract: An arrangement for clamping raw materials in a machine tool for machining elongated workpieces is provided. The arrangement comprises a supporting plate with at least one thoroughgoing opening and at least one clamping device arranged in front of one of the openings. The clamping device has a pair of clamping rings that drive pairs of jaws. When a pair of clamping devices are utilized, the first clamping device may be used primarily for the clamping of profiles, while the second clamping device is designated for round bodies.

Abstract: The machine (1) has a receiving device (13) for clamping the workpiece (14) on one side. A laser optic (12) is movable NC-controlled in the three spatial coordinates x, y, and z for processing the workpiece (14). An additional slide (21) may be displaced longitudinally in a controlled way on the base (3) of the machine frame (2). The slide (21) has a carrier plate (29) having multiple attachment elements, arranged in a regular raster, for replaceable, removable attachment of at least one auxiliary device (37), e.g., a support element (39). In this way, the machine (1) is usable in manifold ways. The quality of the processing may be improved through improved positioning and support of the workpiece, and the clock frequency may be elevated.
