ABSTRACT:
A workholder arrangement which employs a support module which can have one of several different workpiece-engaging units interchangeably mounted thereon so that the same workholder module can be readily adapted to function several different ways, such as a collet chuck, a step chuck and an expanding mandrel. The support module has a housing which attaches to the basic machine tool and slidably supports therein an activating sleeve defining an interior conical surface thereon, the activating sleeve being adapted for direct connection to and being axially movable by a draw or push bar.
