Model CB65-NDR/A8-OS, CB-NDR Collet Chucks - Pull to Close Dead Length Design for Servo Stop Bar Loaders

The CB-NDR is a patented Dead Length design for use with servo stop bar loaders. Unlike conventional dead length collet chucks, the NDR is actuated as the draw tube is drawn toward the machine spindle to prevent the bar from being pushed off the servo stop.

CB-NDR Features
  • Pull to Close Dead Length design produces no pull back and will not push the bar off the servo stop
  • 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
