5c arbor allow to use in headstock to replace typical lathe chuck for more rigid clamping in small part application
Self Centering lathe chuck will open and close all 3 jaws simultaneously
Semi-steel chuck body made from high quality cast iron
3 pinion available around the chuck body to allow easy access for the lathe chuck key to open or close the jaws
Each pinion is ground and hardened to HRC 43
Both sides of the 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 jaws to its designated chuck body, the jaws finish machining is performed on a close tolerance state of the art CNC machine from Japan
The scroll plate's thread flank are ground on both sides to achieve tighter contact with the master jaw
Each chuck has gone through rigorous accuracy and repeatability inspection by clamping and jamming multiple random testing rods or rings
Accuracy is maintained for the entire clamping range
