Northfield Precision Instrument Corporation, a leader in the design and manufacture of precision workholding chucks, introduces their special 5 inch diameter diaphragm chuck with morse taper number three female bore for locators. The chuck has a built-in pneumatic hammer to expel morse taper locators. The diaphragm centers the work piece and pulls it onto the MT-3 stops. The MT-3 type stops (not shown) are hardened and ground to 60/63 RC and ground between centers to guarantee perfect concentricity.
