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