  • Patent number: 9272367
    Abstract: A cutting machine includes a suction duct that is movable with a cutting head of the cutting machine, using a common drive. The suction duct is disposed beneath the workpiece support and coupled to the motion unit supporting the cutting head so that it moves with the motion unit while an opening of the suction duct remains positioned below the cutting head during a cutting operation. The suction duct removes cutting debris and dust, and protects underlying machine components from beam damage.

  • Patent number: 9071031
    Abstract: A radio frequency (RF) excited laser assembly includes a pair of opposed electrodes defining an inter-electrode gap and a conductive termination bridge in electrical contact with both electrodes. The termination bridge mechanically supports and positions the electrodes relative to each other and provides a termination impedance for an RF voltage applied to the electrodes. A conical spiral inductor includes one or more metals windings, and one or more concentric terminals, such that the conical spiral inductor defines an inter-winding spacing sufficient to mitigate ionization of a gas medium between windings. A radio frequency (RF) feed-through assembly configured to apply an RF voltage to a pair of opposing electrodes such that a conductor is isolated from a metal sleeve position around the conductor by ion sheath discharge barrier.

  • Patent number: 8809731
    Abstract: Moving enclosures for laser equipment are provided. A machine tool installation is disclosed, including (a) a laser cutting head configured to be movable in three dimensions; (b) a workpiece support configured to support a workpiece in operative relationship with the laser cutting head; (c) a skirt configured to surround the laser cutting head on three sides and intercept light that passes from the head and is reflected off of the workpiece or workpiece support; and (d) a protective cover positioned to intercept light that is reflected off of the workpiece or workpiece support and is not intercepted by the skirt. The skirt and protective cover are configured to move laterally with the laser cutting head.

  • Publication number: 20140096661
    Abstract: A tool includes first and second tool parts that move toward one another, at least one processing device provided on the first tool part, and at least two counter devices provided on the second tool part. The processing device and the counter devices are rotatable relative to one another about at least one positioning axis, and the counter devices are aligned relative to one another along a direction of relative rotational movement of the processing device and the counter devices. The processing device and a first counter device are allocated to one another by at least a first defined processing parameter, and the processing device and a second counter device are allocated to one another by at least a second defined processing parameter. The first processing parameter is different than the second processing parameter.

  • Patent number: 7778303
    Abstract: An RF excited laser assembly includes a pair of opposed electrodes, and at least one inductor. The pair of opposed electrodes defines an inter-electrode gap that provides a discharge volume for laser propagation within a gas medium. The pair of opposed electrodes define one or more discharge-free regions within a laser-free region in the inter-electrode gap. The least one inductor is electrically connected to both electrodes and extends between the electrodes within the inter-electrode gap and inside of the one or more discharge-free regions within the laser-free region.
