Model 670, 2-jaw, Sliding-Jaw Air Chuck (0.0001” TIR) with special Top Tooling. Our customer needed to grip the OD of a molded plastic part and have access on all 4 sides for machining in 2 setups, rotary and stationary. Specially-contoured Top Jaws along with a shuttle pin for location (not shown) were created and mounted to our standard chuck to achieve this.
