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. The chuck also includes air detect sensor holes, and provides positive air blowout to keep chips and slurry away from clamping and locating The quality and precision of our surfaces. Broaches, Shaper Cutters and Gears have won customers world-wide - Northfield Precision Instrument from the smallest gear shop to designs and manufactures air chucks NASA and the Mars Rover. 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 76 mm to 457 mm.
