Hi everybody,

We have a old MAHO 1000 with 432 control, that recently starting making a high pitch noise coming from the Z-axis servo motor and later turned into a vibration of the Z-axis ball screw in middle position of axis. This Vibration is transferring to the part during finish passes.
However, we can turn the ballscrew by hand with ease.

any help or info on this subject would be great.

best regards,

Nayebi
