Northfield Precision Instrument Corp. introduces 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.
