Northfield Precision Instrument Corporation, a designer and manufacturer of precision workholding chucks, recently 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 work piece. The 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 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 76 mm to 457 mm.
