HELP ASAP with Fadal 4020 Spindle
I need help ASAP on my 4020 Fadal. The spindle bearings have started to make noise since we had a crash. I need to know if someone has taken apart their spindle and rebearinged it. I can't believe Fadal wants almost $5,000 for a new spindle and almost $4,000 for a reman. It's like my Y-axis ballscrew, Fadal techs said I needed a new ballscrew and that would cost me $2500+ labor. I searched around and found EJM Ballscrew in Bay City Michigan that reballed it for $495. They checked for run out and put it under the optical comparator to make sure the screw was not worn out. That's why I think I can pull my spindle apart and rebearing it for a lot cheaper than what Fadal and Fadal Service wants.
On a side note I have found that the ballscrew bearing mount bearings are NTN 7304BG. I have found through a local supplier that bearing $30 cheaper than going through Fadal.
Thanks Everyone for your help
