Shafts can be machined complete between centers with MicroCentric's retractable collet chuck. A face driver mounted in the ID of the chuck drives the shaft as it is supported by the tailstock to turn the end of the shaft. When the chuck is actuated the collet moves forward to clamp the turned diameter enabling the OD of the shaft to be machined completed while the end of the shaft is securely clamped.

WSF Features

  • Mounting for face driver in ID of chuck assembly
  • Radial adjusting screws to true-up chuck assembly within .0002” (0.005mm)
  • All components hardened and precision ground for highest accuracy and long life
