Sliding Jaw Air Chuck

Island Park, NY -  Northfield Precision Instrument Corporation, designer and manufacturer of precision workholding chucks, introduced their Model 1000 Sliding Jaw air chuck. This air chuck, with 0.0001” TIR, has a special Top Tooling and Axial Locator. This particular air chuck was custom designed for a gaging company that needed to grip a small area of a large casting so they could check OD runout of their part. Special, tall Top Jaws are diamond-coated for a secure grip on the casting.  An Axial Locator with button pads is used as a resting surface for the part’s flange while swallowing the rest of the part.  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.
