Expanding Collet Chuck


Island Park, NY… Northfield Precision Instrument Corporation, a leader in the design and manufacture of precision workholding chucks, introduces their newest expanding Mandrel Collet Chuck.



This chuck was custom-designed for a customer to clamp the minor diameter of an internal spline. While clamped, the customer machines the internal counter bore, the outside profile, and the face of the work piece.



This chuck also includes air detect sensor holes, and provides positive air blowout to keep chips and slurry away from clamping and locating surfaces.



Northfield Precision Instrument designs and manufactures the world’s most accurate air chucks for any lathe, boring machine, grinder or VMC. Models include through-hole, highspeed and quick-change. Chucks are available in SAE or metric, in sizes from 3” (76mm) to 18” (457mm). Accuracies of 0.001” to 0.00001” (0.254m) are guaranteed. Custom workholding chucks and jaws are available and FREE engineering assistance is offered.
