Description
Product Overview
High-precision diaphragm chuck for universal machining applications. The Master Jaw Diaphragm uses a flexing diaphragm (no sliding parts) to provide repeatable concentricity and reduced wear for internal and external clamping operations.
Included Components
Advantages
Technical Features
Air is introduced through the spindle and adapter plate via a 1/4" pipe. When air pressure is applied the piston advances approximately 0.030"; a push sleeve transmits this movement to the diaphragm. As the diaphragm flexes the jaws open and the workpiece is loaded. To chuck, air is vented and the diaphragm relaxes so the jaws move until they contact the part, centering it. Consistent concentricity is maintained with a maximum runout controlled to one-third of the part tolerance.
