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.
