January 15, 2014—Northfield Precision Instrument Corporation introduces their Model 670 air chuck. This chuck has 2 sliding jaws (0.0001” T.I.R.) with special top tooling. Northfield’s customer needed to grip the OD of a molded plastic part and have access on all 4 sides for machining in 2 set-ups – rotary and stationary. Specially-contoured top jaws, along with a shuttle pin for location (not shown), were created and mounted to Northfield’s standard chuck to achieve this. Northfield Precision Instrument designs and manufactures the world’s most accurate air 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” (76 mm) to 18” (457 mm). Accuracies of 0.001” to 0.00001” (0.254 m) are guaranteed. Custom workholding chucks and jaws are available and free engineering assistance is offered.
