- Both side of jaw teeth and guides are ground and hardened to HRC 58-62
- Each set of jaws are serialized in their own set
- A serialized set of jaws are then finished, ground, and lapped on their designated chuck body which will be the same chuck body on the final assembly to achieve a greater accuracy
- Before assembling the jaw to its designated chuck body, the jaw's finish machining are performed on a closed tolerance state of the art CNC machine from Japan
