  • Patent number: 10118267
    Abstract: Provided is a machine tool with a machine rack constructed of structural parts and components mounted thereon, the components including functional components. The functional components generate heat during the operation of the machine tool which is input into the structural parts and/or the components by heat transport. The machine tool may also include a flow channel system disposed on the structural parts and/or the components of the machine tool in which a tempering medium is circulated such that the heat generated by the functional components is distributed in the machine rack and/or the components as a result of the passage of the tempering medium.

  • Patent number: 7101129
    Abstract: A machine tool for machining large-area workpieces. A column can be moved along one coordinate axis over a long bed. A machining unit, movable at the movable column along at least two other coordinate axes, has a pivotable working spindle. At least one approximately plate-like work carrier can be pivoted from a horizontal set-up position into a vertical machining position. A tripod configuration of the machining unit has a central support pipe and three telescopic legs spaced about 120° with respect to one another. The movable column has, in a central recess, a universal bearing supporting the central support pipe. In each of two lower and one upper recesses a universal bearing for the telescopic legs is provided. A retainer supporting the pivotable working spindle is positioned next to the work area on one end of the central support pipe and is rotatable about an axis of the central support pipe.

  • Patent number: 6428453
    Abstract: A machine tool for cutting workpieces, the machine tool having a tool slide shiftable on or along a machine tool table as support of a machining unit. The machining unit has at least one work spindle and a workpiece support for receiving the workpieces to be machined. For enabling fast machining including an accurate and rapid positioning of the machining unit with as few linear guidances as possible, the tool slide has a transverse support shiftably guided on or along the machine tool table and also has two cross slides shiftable in its longitudinal direction. The machining unit is jointedly arranged between the cross slides via a coupling mechanism having at least two dimensionally stable swivel arms for axially moving the work spindle.
