CB-NB/S Collet Chucks - Pull Back Design

Check up to five results to perform an action.

In the CB-NB/S series collet chuck, the master collet is coupled directly to the draw tube connector. As the draw tube is actuated, the master collet is drawn into the tapered seat of the chuck body, efficiently translating draw tube force into maximum clamping force.

CB-NB/S Features
  • Pull Back design maximizes the efficiency of the clamping system by concentrating all forces in the direction of the spindle for highest accuracy and greatest overall rigidity.
  • Low profile OD and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis travel compared to conventional master collet chucks
  • Radial adjusting screws for fast, accurate adjustment
  • Lubricated-for-life design requires minimal maintenance
  • 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
