ABSTRACT:
A chuck for holding an easily distortable hollow workpiece has a rigid body with axially extending co-extensive, circumferentially spaced, flexible chuck fingers carried on a mounting surface. Each of the fingers has one end axially fixed to the mounting surface and an opposite free end which is swingable radially to grip a radially adjacent workpiece. An inflatable ring, mounted on the chuck body radially adjacent the fingers is in engagement with the fingers and, when the ring is inflated, moves the free ends of the fingers radially to grip the workpiece.
