Northfield Precision Instrument Corp., a leader in the design and manufacture of precision workholding chucks, introduces their Model 450 Air Chuck. The Model 450 Air Chuck (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.
