Northfield Precision Instrument Corp. introduces its standard Model 470 2-jaw sliding-jaw Air Chuck with highly specialized top tooling. This tooling was developed in conjunction with our customer to allow side-loading of their part (not shown) into the very center of the small cylindrical insert pads (which have been wire-cut from solid for accuracy) at the top of the photo. These insert pads are changeable (and held on-center to the chuck's OD within their subjaws as shown) to accommodate different sizes of the customer's part.

The subjaws themselves have a large milled pocket, to clear their part. This was a lathe application where Northfield Precision met the required accuracy / repeatability of .0001" TIR or better when mounted on the customer's spindle.
