Abstract
A chuck for machine tools has basic jaws which engage with attachment jaws which are exchangeably retained and can be fed by means of a pallet and attached through a relative rotation mechanism between the jaws, each basic jaw is provided on its face with a specially shaped projection and each attachment jaw is provided with a corresponding, laterally open recess. The radially oriented surfaces of these parts are concentric to the longitudinal axis of the chuck body and furthermore, the attachment jaws are locked to the basic jaws secure against rotation by a holding member in a chucking position. This makes it possible to exchange the attachment jaws easily and quickly with the aid of machine motions and, in addition, there is an assurance of safe support of the attachment jaws on the basic jaws.
