Northfield Precision Instrument Corp. introduces its Model 450WHF chuck. It uses a special four-port air tube and a special piston to allow for open/close/autolube/air-detect functions. The top plate (with pin) is a radial banking surface (side of pin only), which picks up the side of the customer's part when it is loaded and twisted into position into the chuck. The three small pads with tiny holes in the center of the chuck are used to rest the part against the tops of the pads while the holes are used for the air-detect function.
