摘要： The invention relates to an insulation part for supporting an electrically conductive nozzle in an insulated manner, and a laser machining head with a housing (10), through which a working laser beam path (11) is guided, which exits on the machining side through an electrically conductive nozzle (17), which is supported on an insulation part (18), which is supported on the housing (10), and which, for the capacitive distance measurement, is electrically connected to an oscillating circuit (24) of a distance measuring circuit (22). To be able to monitor the presence of an inexpensive insulation part (18) in a user-friendly manner, it is provided according to the invention that the insulation part (18) comprises a ferromagnetic body (26) and that a sensor (27) for detecting the ferromagnetic body (26) is provided on the housing (10), said sensor being connected to a monitoring circuit (29), which, in the absence of an insulation part (18), outputs a warning signal.

摘要： A method for preparing a precoated sheet is provided. The method includes providing a precoated sheet having a metallic substrate with a precoating on at least one of its faces and removing through laser ablation at least a portion of the precoating on the at least one face of the precoated sheet in a removal zone. The ablation step is carried out in an installation. The installation includes at least one protective element having a protective surface. During the ablation step, the protective surface contacts the precoated sheet in a contact area in register with the laser beam as the laser beam removes the portion of the precoating. A plane tangent to the protective surface at the contact area forms a dihedral angle with the plane of the face of the precoated sheet. This angle is strictly smaller than 90°.

摘要： A method for the generative production of a component and a device for carrying out such a method, includes the following steps: applying a material layer with a constant layer thickness; solidifying a region of the material layer according to a component cross section; generating an eddy-current scan of the solidified region, a scan depth corresponding to a multiple of the layer thickness; determining a material characterization of the solidified region taking into consideration a previous eddy-current scan of solidified regions of lower-lying material layers; and repeating the steps until the component is assembled. An electric material characterization of each individual layer is determined using a recursive algorithm of individual measurements (monolayer by monolayer), and thus the entire component is tested step by step completely in a highly resolved manner.

摘要： In a Sapphire Collector (SC), one or more features, both structural and parametric, are included for capturing the die-size sapphire chips that are removed from a semiconductor structure during die-level laser lift-off (LLO). These features are designed to increase the likelihood that each sapphire chip is securely captured by the Sapphire Collector immediately after it is released from the semiconductor structure.

摘要： A laser cladding apparatus includes a powder supplier to supply metal powder to a portion to be processed, a laser to irradiate the portion to be processed with laser so as to melt the metal powder for cladding, and a controller. The powder supplier includes a gas pressure gauge, and the controller stores, as an initial value, a gas pressure value measured by the gas pressure gauge when the metal powder supplied by the gas pressure reaches the portion to be cladding-processed. In operation after storing the initial value, the controller sets, as a reference time, timing when the gas pressure gauge measures a same pressure as the initial value, and outputs a start signal for laser irradiation to the laser based on the reference time.

摘要： The disclosure relates to mechanical support rail cleaners for cleaning support rails of workpiece supports in machine tools, such as in machine tools for thermally cutting workpieces. The cleaners include one or more cleaning member carriers, which carry at least one cleaning member, and a parallel drive, by means of which the cleaning member and the support rail can be moved relative to each other in parallel with a lateral longitudinal face of the support rails and transversely relative to a longitudinal axis of the support rail to remove deposits from the support rail by means of the cleaning member. The support rail cleaner further includes a transverse drive configured to periodically move the one or more cleaning member carriers and the support rail towards and away from each other transversely relative to the lateral longitudinal face of the support rail.

摘要： The invention relates to machines for the separative machining of plate-shaped workpieces using a machining tool. The machines include two workpiece support surfaces for supporting the workpiece, between which a gap is formed, and at least one carriage that is movable in or along the gap, and is connected to at least one covering element. The covering element at least partially covers the gap and includes a chain with a plurality of chain links. The chain links can have a brush support on an upper side and are designed to pivot with respect to one another, wherein at least two mutually adjacent chain links have a pivot-limiting angle (α) with respect to the longitudinal axis of each of the chain links such that, with a rectilinear orientation to one another and without exposure to force, the chain links assume a non-planar profile.
