Abstract: A device for the thermal processing of a workpiece with a fiber laser, which generates laser radiation with a wavelength in a range, in particular, from 1020 nm to 1120 nm. The device includes a laser processing machine, having a support surface for the workpiece, a laser processing unit with a laser machining head, and a movement unit with a transverse gantry for moving the laser processing head relative to the support surface. A laser protective hood surrounds the laser processing head, is open towards the support surface, and is movable by the movement unit together with the laser processing head. The protective hood has an outer wall and an inner wall, and a cavity therebetween. At least one laser-light sensor is arranged in the cavity. A laser protection housing surrounds the laser processing machine and the protective hood in a hood-like manner.

Abstract: Disclosed is a device for aligning a workpiece in a mass-centring device, in which in an initial position an upper flange (1) and a lower flange (2) are arranged concentrically around an axis (3) of a balancing spindle of the mass-centring device, with the upper flange (1) comprising an interface (4) for clamping means to clamp the workpiece, and the lower flange (2) an interface (5) for fastening means to fasten the device to the balancing spindle. At least two spring elements (22, 23) reside between the upper and the lower flange (1, 2), such that in the initial position the upper flange (1) takes support axially and radially exclusively on the two spring elements (22, 23). In the initial position, the upper flange (1) is movable relative to the lower flange (2) into an eccentric position by a force acting in opposition to the spring elements (22, 23).

Abstract: Disclosed is a method for determining the static unbalance of a body (30) provided with a locating surface (31) by means of a center-of-gravity weighing scale (10), the method including measuring the position of the locating surface (31) of the body (30) with respect to its mount by means of electric displacement sensors (16), computing from the measurement signals of the displacement sensors (16) the eccentricity of the locating surface (31) of the body (30) with respect to the reference point of the scale (10) by means of an electric evaluating circuit, weighing the body (30) and recording mass and position of the center of gravity of the body (30) with respect to the reference point of the scale (10), and computing the unbalance of the body (30) from the measurement signals of the scale (10) and the eccentricity of the locating surface (31) of the body (30) with respect to the reference point of the scale (10) by means of the evaluating circuit.
