6-jaw turning chuck / precision / diaphragm
Number of jaws:
The diaphragm principle as applied to chucking utilizes the inherent strength and accuracy of spring steel to achieve chucking pressure on internal or external surfaces. Applications of this principle have been production proven. Diaphragm chucks are used primarily for secondary operations, such as grinding, boring facing and light turning. Locating surfaces should be pre-machined or a precision cast surface.
