  • Four operating screw design with each ground and hardened to HRC 43
  • Both side of jaw teeth and guides are ground and hardened to HRC 58-62

  • Four jaws allow a square component to be perfectly centered to the chuck while achieving maximum gripping force
  • 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
