Northfield Precision Instrument Corporation, a designer and manufacturer of precision workholding chucks, has introduced the Model 450 Air Chuck. The 450 (with special top tooling) mounts on a pallet which installs on the bed of the customer's machine. The machine's pick-and-place arm picks up the parts after they are finished in the front (2) chucks and transfers them to the rear (2) chucks for finishing. All hosing is routed under the plate for actuation of the chuck's jaws. Northfield models include through-hole, high-speed and quick-change and 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) guaranteed. Custom workholding chucks and jaws are available and fREE engineering assistance is offered.
