Expanding Collet Chuck

Northfield Precision Instrument Corporation has introduced its 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 workpiece.

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 accurate air chucks for any lathe, boring machine, grinder or VMC. Models include through-hole, high-speed and quick-change. Chucks are available in SAE or metric, in sizes from 3" (76 mm) to 18" (457 mm). Accuracies of 0.00001" (0.254 m) are guaranteed. Custom workholding chucks and jaws are available and free engineering assistance is offered.
