  • 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: 7161114
    Abstract: A machine tool installation for laser cutting of sheet metal workpieces includes a workpiece support having a multiplicity of parallel spaced grid elements providing the upper surface thereof, and a machine frame having a generally vertical rear wall and an arm extending therefrom over the workpiece support, and upon which is supported a laser cutting unit with a laser cutting head, said grid elements of said workpiece support extending perpendicularly to said vertical wall of said machine frame. An unloading unit is provided to lift the cut parts from the workpiece support and transport them to a discharge station. In the unit a frame movably supports a pair of opposed fork assemblies which move between open and closed positions. These fork assemblies are spaced apart in the open position and have their opposed ends in adjacent relationship in the closed position, and they are movable vertically to enable the forks to be moved between the grid elements to pick up the parts.

  • Publication number: 20050103764
    Abstract: A machine tool for machining workpieces by motion of a machining tool relative to the workpiece has a worktable and a frame extending above the worktable. An X-axis motion unit is movable along the X-axis in a first range of motion. A first machining tool mount is movably mounted on the motion unit for movement in the Y-axis in a second range of motion, and a second machining tool mount is movably mounted on the first machining tool mount for movement in the X-axis within a third range of motion of lesser length than, and within the length of, said first range of motion. A machining tool is mounted on the second machining tool mount, and drives motors are provided for the motion unit on the frame, the first machining tool mount and the second machining tool mount in their respective ranges of motion and axes. A computer control effects operation of the several drive motors to move the machining tool in the X- and Y-axes and to drive the second machining tool mount more rapidly in the X-axis.
