CB-NB Collet Chucks - Pull Back Design

 
Check up to five results to perform an action.

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

CB-NB 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
  • 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
