The invention relates to a clamping means (1), in particular for a chip-removing machine, comprising a chuck body (2) with several circumferentially distributed clamping elements (3) and circumferentially distributed centering elements (4), which are supported inside the chuck body (2) and which are movable via control elements. To achieve the greatest possible precision in workpiece machining, a centering is provided with the clamping means (1) according to the invention, which clamping means are acted on by a common control element before the clamping elements (3) clamp the workpiece to be machined. The clamping means (1) according to the invention are therefore particularly suitable for machining pipes, in particular pipe ends, in order to achieve the necessary precision. |
