How to choose this product
Diaphragm chucks use compressed air to open and close the jaws holding workpieces on lathes. They offer improved accuracy and axial symmetry during turning operations.
Diaphragm chucks are primarily used for light-duty turning operations such as fine boring, facing and grinding. They are used on computer numeric control (CNC) lathes equipped with a compressed air system.
The diaphragm chuck uses a compressed air piston or drawbar to open the diaphragm, allowing the workpiece to be mounted within the jaws. As the piston is retracted, the jaws close, holding the workpiece in place. The diaphragm is made of spring steel and the base of the jaws from hardened steel.
How to choose
Be sure to determine the approximate diameter of the workpiece when selecting a diaphragm chuck.
