Abstract
A chuck for a machine tool is provided and includes a chuck body that is provided with a frusto-conical opening that has guide surfaces. A clamping head is adapted to be received in the opening of the chuck body, with the clamping head having an axially extending receiving opening for workpieces, cooperating with a drawing mechanism, and being provided with gripping jaws that have mating guide surfaces. The guide surfaces of the opening of the chuck body have a pressure connection with the mating guide surfaces of the gripping jaws. The clamping head is provided with radially oriented receiving opening for the gripping jaws, which are radially movable in the receiving openings. The gripping jaws each have a width that is less than an inner radius of the opening of the chuck body.
