Stationary Air Chucks are ideal for milling, drilling, tapping and other applications requiring a compact self-contained work holding fixture. The air is supplied directly into the side of the chuck body and the chuck can be mounted directly to the machine table or pallet. This family of chucks was developed in order to find an economical chucking solution for index tables, rotary tables, pallet changers and other rotating elements for the CNC machining operations. The chuck can get the air for open/ close the jaws while rotating.
