Northfield Precision Instrument Corporation has introduced its Model 700 air chuck. This 7" diameter, 3-jaw air chuck has special jaws that grip a short diameter of the automotive "hub" shown to drill and chamfer the five holes. A special stop mounted to the chuck face has "air detect" holes for part seating confirmation. The stop is contoured and relieved to allow a chamfering tool to break the edge on the banking surface of the workpiece.

Northfield Precision designs and manufactures air chucks for lathes, boring machines, grinders and VMCs. 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 0.001" to 0.00001" (0.254 m) are guaranteed.
