  • Device for the tailstock end centering and clamping of a workpiece with a circular-cylindrical end
    Patent number: 6585573
    Abstract: The device according to the invention for the tailstock end centering and clamping of a rotational workpiece with a circular-cylindrical end comprises a housing with a shank for accommodation in a tailstock barrel, and a chucking pot with a collet located in the housing for rotation about the axis of rotation of the workpiece. In accordance with the invention the collet is closable by way of the axial advancing action of the tailstock, and the axial tailstock thrust effecting the closing and clamping of the collet is transmitted to the workpiece in such manner that it is applied to the center of the workpiece, and the latter is displaceable into the center without friction generating radial sliding of the collet.

  • Detachable, high precision and rigid connection of a tool, workpiece or gauge holder to the nose of a machine tool spindle
    Patent number: 6553876
    Abstract: Interface between the spindle nose (1) and the fixture flange (11) of interchangeable tool, gauge or workpiece holder (7) of a machine tool with a shortened centring taper (8) on the underside of the flange of the holder (7), said taper being formed as an axially and radially rigid but in circumference elastically expansible tubular stub (15), which due to its elastic properties adapts itself to the diameter of the centring taper (6) on the spindle nose (1).
