Ballscrew Backlash

Post by JPac » Fri 16 Nov , 2018 17:08 pm

Hi all. I have measured backlash of 0.12mm on the X, all of this seems to be on the ballscrew/nut interface. This seems rather excessive..... Y and Z are around .05. My machine is from Jan 2000, and has a single ball nut on X.
Am I right that there's no adjustment possible with the ball nut?
Is it possible to fit a new 1605 double ball nut without also replacing the screw?
