Abstract: A mechanical arrangement for processing sheet metal includes a sheet metal processing device, a transport device configured to position a sheet metal workpiece relative to the sheet metal processing device, the transport device including at least one workpiece carrier that is movable along a transport path that extends along a first transport line and a second transport line, and at least two X-guides and at least two Y-guides, the X-guides arranged parallel with the first transport line and the Y-guides arranged parallel with the second transport line. The at least two X-guides and the at least two Y-guides are configured to be coupled to each other by a transfer device to form a transport course, the workpiece carrier circulates along the X-guides and the Y-guides, and the transfer device is configured to move the workpiece carrier from one of the X-guides to one of the Y-guides.

Abstract: A laser processing machine includes a laser that outputs a laser beam, a laser processing head including a nozzle that defines a nozzle bore, a beam guidance and focusing system for directing the laser beam through the nozzle bore of the laser processing head, an illumination system that produces a light beam that is directed at the nozzle bore of the nozzle such that the light beam completely illuminates the nozzle bore, a light detector at the nozzle bore that views light that exits the nozzle bore, and an evaluation system that receives the output of the light detector and automatically determines the separation between a center of the laser beam when the laser beam is focused at the nozzle and a center of the nozzle based on the light detector output.

Abstract: In a bearing support (10) for a laser resonator, adjacent support sections (11a, 11b) are directly and undetachably connected to each other by an articulated deflectable joint (12). An additional vertical safety on the bearing support is no longer necessary since the two support sections (11a, 11b) are already held together in a vertically secure manner by the articulated joint (12).

Abstract: An apparatus for deflecting a laser beam includes a deflecting mirror disposed in a holder, a lever, a rotatable coupler, and a drive member. The mirror is pivotable about a first pivot axis lying on a surface of the mirror, and the holder is rotatable about a second pivot axis oriented substantially perpendicular to the first pivot axis to cause the mirror to rotate about the second pivot axis. The lever is coupled to the mirror along a first lever axis parallel to and separated from the first pivot axis. The rotatable coupler is coupled to the lever along a second lever axis parallel to and separated from the first pivot axis, the coupler is rotatable about the second pivot axis, and the rotatable coupler and the holder are longitudinally translatable relative to each other along the second pivot axis. The drive member is coupled to the holder, and the drive member is longitudinally translatable along the second pivot axis to cause the mirror to rotate about the first pivot axis.

Abstract: A machine tool installation (1) for the processing of workpieces includes encompasses a work area (4) for the machining of workpieces and contains a workpiece support (13), a work area enclosure (3) featuring a gate (7) and at least one corresponding door segment (6/1, 6/2, 6/3) which can be moved in the horizontal direction between open and closed positions and is supported on the substructure of the machine installation (1) in horizontally movable fashion. Provided above the substructure of the machine tool installation (1), and attached solely to the workpiece support (13) is at least one stationary guide element (14, 15) for the door segments (6/1, 6/2, 6/3) and extending over at least part of the width of the gate.
