ABSTRACT:
In an arrangement for coupling a false jaw to a master jaw of a chuck, wherein a positive locking is effected by a radial displacement, the master jaw is provided with an extension having a stop surface and a projection. The false jaw has a recess for receiving the extension and a relief shoulder and is guided in the direction of rotation. Due to this arrangement, the false jaw is well supported and highly stable, so that strong forces can be transmitted, and a high repetitive accuracy in chucking is obtained.
