Retooled Modified Air Chuck
Northfield Precision Instrument Corporation is a leader in the design and manufacture of precision workholding air and diaphragm chucks. Northfield manufactures precision air chucks with a guarantee of accuracy within millionths. We have come to be the precision workholding source for air & diaphragm chucks with workholding leadership in accuracy, reliability, repeatability, concentricity, productivity and customer service. Now expanded application for standard air chuck features new workholding advantages with retooling.
These are a couple of Model 470 precision sliding air chucks we retooled for Caterpillar. The part shown being gripped in one of the chucks is a "Wheel Poppet Adapter". This special air chuck has special serrated insert pads to securely grip the part during the operation where they are drilling the holes on the side of the part. (The chuck is mounted on an indexing head to expose the side of the part for drilling).
The plates attached to the sides of the jaws are used as a datum for drilling; one plate flexes to push the part such that it maintains positive contact against the solid Plate on the opposite side.
The chuck also has an axial locator mounted in the center with line contact so as not to influence the grip of the part, but acts as a secondary datum. Please visit our website at www.northfield.com
