Abstract
The invention relates to a clamping chuck head for clamping a workpiece to be processed. The clamping chuck head comprises a rotatably supported clamping chuck having a first set of clamping segments for clamping a workpiece on a first perimeter area, an operating device for operating the first set of clamping segments, wherein the operating device comprises at least one spring element which closes the first set of segments for clamping the workpiece due to its bias; and a main sleeve in which the first set of segments is arranged, wherein the main sleeve is rotatably supported in the clamping chuck head on two bearings axially spaced from each other and the operating device is essentially arranged in an axial direction between the two bearings or in the area of the bearings.
