Are there any recommendations for reasonably priced ball screw ball nut rebuild services? I bought a machining center that was pulled from service because no one really wanted to use it any more and the claim was that it won't hold tolerance anymore. As much as .015" out. I got it for scrap, but really hate to strip it and send it to the scrap yard. Will check more closely once we get it home, but it could only be thrust bearings, ball screw wear or gib adjustment. Gib is the easy part to check and adjust.

If anyone has experience with a particular shop you were happy with let me now or post here so others will know.
