• CB-NX picture

The CB-NX series is a low profile dead length design with a reduced diameter nose for maximum tool clearance. The collet is coupled directly to the chuck body and remains fixed as the tapered seat moves forward when the chuck is actuated. The collet remains fixed in the Z axis during clamping and therefore does not create a pull back effect on the bar stock or workpiece.

CB-NX Features

  • Low Profile Dead Length design
  • Reduced diameter nose and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis
  • Radial adjusting screws to true-up tapered collet seat 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, stop housings, and ejectors can be mounted inside the chuck body for chucking applications
