  • Patent number: 11897069
    Abstract: A device for stabilizing a workpiece, in particular a thin-walled workpiece mounted in a machine tool, comprises at least one base; and a plurality of stabilizing elements. The stabilizing elements protrude away from one surface of the base, wherein the stabilizing element comprises a cylinder and a rod arranged therein and the rod can be driven hydraulically to move in the axial direction of the stabilizing element such that the rod of at least two of the stabilizing elements can be brought into contact with one surface of the workpiece.
    Type: Grant

  • Patent number: 11292096
    Abstract: The machine tool has a machine bed having a first horizontal linear guide and a second horizontal linear guide arranged at right angles to the first linear guide. On the first linear guide is arranged, in an axially displaceable manner, a workpiece clamping fixture, which is swivelable about a swivel axis oriented parallel to the second linear guide and is rotatable about a rotation axis oriented at right angles to the swivel axis. On the second linear guide a toque motor driven swivel arm is axially displaceable, the swivel axis of which is arranged parallel to the first linear guide and which on its free end bears a tool spindle, the axis of which is oriented parallel to the first linear guide.

  • Patent number: 10219612
    Abstract: The brushing device contains a bundle of fiber rods (1), which are arranged parallel to one another, and a protective sleeve (2), which encloses the fiber rods. Once fiber rods (1) have become worn, the protective sleeve (2) is able to be axially adjusted, so that the free ends of the fiber rods (1) protrude beyond the protective sleeve (2) by a desired amount. A first component (4) connected to the fiber rods (1) and a further, second component (8) connected to the protective sleeve (2) are detachably connected to one another, in a non-positively locking manner, by a clamping mechanism (3, 5, 11).
