Product Spotlight



  • Semi-steel chuck body made from high quality cast iron
  • 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

Fully Machined Threaded Back Plate

 

Fully machined back plate can be directly mounted onto our 6" 3 jaw or 4 jaw self centering lathe chuck (p/n 202-5433, 202-5411, 202-5473). 

 You would not need to drill any mounting holes but you will need to turn the shoulder down .050" to match the back of the lathe chuck to make the chuck & back plate more concentric with the lathe spindle. When turning the shoulder of the backing plate, ONLY TURN THE SHOULDER OF THE BACKING PLATE WHEN ATTACHED TO THE LATHE SPINDLE. If you use a chuck to clamp the backing plate and then turn it, the backing plate will not be true to the lathe spindle and will have more runout than specified when the chuck and back plate are put together.
