Pneumatic Chuck suits boring, milling, lathe applications.June 20, 2008 -
Model 1200 air chuck incorporates precision, quick change sub-jaws. Top jaws have tre-panned groove that engages with precision ground bore of sub-jaws. As jaws are tightened, flexible tab expands into tre-panned groove, pulling jaws against ground bore and loading jaws in position with zero play. This results in top-jaw/sub-jaw connection with repeatability to 1/10,000. Chucks are stainless steel and come in 2- and 3-jaw design.
