The ND series models are used for collet sizes 120mm and larger. The collet is coupled directly to the chuck body and remains fixed as the tapered seat moves forward when the chuck is actuated. Since the collet remains fixed in the Z axis during clamping it does not create a pull back effect on the bar stock or workpiece.

CB-ND Features

  • Dead Length design
  • Radial adjusting screws to true-up the chuck assembly within .0002” (0.005mm)
  • Lubricated-for-life design requires minimal maintenance
  • All components hardened and precision ground for highest accuracy and long life
  • Stop plates and stop housings can be mounted inside the chuck body for chucking applications requiring end stops or part ejectors
