- Accuracy is maintained for the entire clamping range
- Semi-steel chuck body made from high quality cast iron
- Three operating screw design with each ground and hardened to HRC 43
- Two piece jaw design with a master jaw and a top reversible jaw in American Standard tongue and groove specification
- 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
- Operating screw's thread flank are ground on both side to achieve a tighter contact with the master jaw
- Each chuck has gone through rigorous accuracy and repeatability inspection with clamping and jamming multiple random testing rods or rings
