CB-NS/S Collet Chucks - Sub Spindle Design

Check up to five results to perform an action.

The CB-NS/S series is a low profile dead length collet chuck designed especially for sub spindle applications. The master collet is coupled to the chuck body and remains stationary as the tapered seat moves forward during clamping. This design keeps the collet in a fixed Z axis position as the chuck is actuated, and does not create a pull back effect on the bar.

CB-NS/S Features
  • Dead Length design produces no pull back on the workpiece
  • Reduced chuck OD for maximum clearance on sub spindles
  • Short overall length provides increased tool clearance and maximum utilization of the machine's Z axis travel compared to conventional master collet chucks
  • Internal mounting for ejectors and stops
  • All components hardened and precision ground for highest accuracy and long life
  • Vulcanized master collet and rubber face seal inside chuck body eliminates chip and coolant contamination
  • Spindle speeds up to 6,000 rpm
