ABSTRACT:
An air operated chuck includes a plurality of hooks arranged in a circle and joined in relative positions by a ring. A membrane holds workpieces of various sizes and shapes on the rotating main shaft of a machine tool with a minimum of vibration or off center mounting for precise machine functions. This is accomplished through the use of interchangeable hook attachments. Each individual hook attachment is adapted to a shape and size range of workpieces. The ring retains the hooks centered about the central axis of the chuck body, thus requiring minimal installation adjustment or balancing. A nonrotating air tube reduces vibration due to an unbalanced air hose.
