  • Patent number: 7963527
    Abstract: A chuck (10) has a chuck body (12), which is provided with three guide devices (24), on each of which is received a radially movable clamping holder (34) for fixing a workpiece to chuck body (12), the guide device (24) being constructed separately from the chuck body (12). Guide device (24) is integrally joined by a polymer concrete filling (46) to the chuck body (12) for a force transfer between guide device (24) and chuck body (12). There is no need for a particularly precise manufacture of the outer contour of guide device (24) and the recess (20) in chuck body (12), because the polymer concrete (46) is able to compensate tolerances.
