Model 470 Air Chuck
Island Park, NY... Northfield Precision Instrument Corporation, a leader in the design and manufacture of precision workholding chucks, introduces their 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.
Northfield Precision designs and manufactures the world's most accurate air chucks 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 3" (76mm) to 18" (457mm). Accuracies of 0.001" to 0.00001" (0.254m) are guaranteed. Custom workholding chucks and jaws are available and FREE engineering assistance is offered.
