Northfield Precision Instrument Corporation, a leader in the design and manufacture of precision workholding chucks, retooled their Model 450 chuck. This chuck has special serrated insert pads to securely grip a part for the drilling of 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, so that it
maintains positive contact against the solid plate on the opposite side. In addition, 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.
Northfield Precision designs and manufactures the world’s most accurate 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,
air chucks and jaws are available and FREE engineering assistance is offered.
