Northfield Precision Instrument Corp. introduces its Model 670 air chuck. This chuck has two sliding jaws (0.0001" TIR) with special top tooling. The customer needed to grip the OD of a molded plastic part and have access on all four sides for machining in two setups: 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.
