ABSTRACT:
Workpiece chucking apparatus includes a chuck body mounting a first plurality of lock-up fingers and a second plurality of gripping fingers. The lock-up fingers are individually biased radially outward into engagement with a peripheral wall of a workpiece to initially support the workpiece in a predetermined position irrespective of the eccentricity of the peripheral wall with respect to other portions of the workpiece which are first located concentrically with the chuck axis. An inflatable bladder flexes the remaining gripping fingers into gripping engagement with the peripheral wall to further radially support the wall in preparation for machining, without disturbing the prepositioning of the workpiece.
