20120267352 | Apparatus for the thermal processing of a workpiece - An apparatus for the thermal processing of a workpiece with a thermal processing tool that is adjustable perpendicularly to the workpiece surface has a drive for adjusting the work distance. The drive is in operative communication with the processing tool or part of it, and is configured as a voice coil actuator, comprising a magnet producing a magnetic field, and a coil in the magnetic field. The magnet and coil are movable relative to each other along a movement axis in response to an electric current. To provide a drive for a thermal processing machine that affords a compact structural form and high machine dynamics, the magnet has a cavity, which has arranged therein the processing tool, or a part thereof, which is mechanically connected to the voice coil actuator. | 10-25-2012 |
20120024832 | Method and apparatus for the thermal treatment of a workpiece by means of a laser beam - In the thermal cutting of a workpiece by means of a laser beam, said beam is generated by means of a laser source and supplied to a movable laser head. In the laser head, an optical deflection element is provided for deflecting the laser beam such that, when viewed in working direction, it encloses a tilt angle (α) differing from 0 degrees with the longitudinal axis of the laser head. Starting therefrom, to produce the inclination of the collimated laser beam to the vertical with a very small number of optical components if possible, the invention suggests that the laser beam is supplied to the laser head by means of an optical fiber and the laser beam is collimated, passes through the deflection element laterally offset to the longitudinal axis of the laser head and is deflected by means of said element onto the workpiece surface and focused at the same time. | 02-02-2012 |
