The CB-NDR is a new patented Dead Length design collet chuck to be used with servo stop bar loaders. The NDR chuck is actuated as the draw tube is pulled into the machine spindle. The collet is coupled to the chuck body and remains stationary as the tapered seat moves forward during clamping. This feature keeps the collet in a fixed Z axis position, and since the draw tube is moving into the spindle, the bar remains positioned against 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
  • Lubricated-for-life design requires minimal maintenance
  • All components hardened and precision ground for highest accuracy and long life
  • Spindle speeds up to 5,000 rpm
