We are experiencing runout while rotating the lathe.  How do you handle getting the runout under control?



While rotating the lathe at approximately 40-50 RPM the rotary seal extension tube should have only a small amount of runout to prevent seal movement, possible connection leakage, and potential tube cracking. If there is significant runout, the handle should be straightened before proceeding with the setup. Failure to correct this can cause issues during the deposition process potentially leading to a lost fabrication attempt.

Update: We have sections on Loading the tube onto the lathe, Initial deposition tube straightening and The final tube straightening/stress relieving process in our blog, Preparing to Manufacture an Optical Fiber Preform.
