RE: [CAD_CAM_EDM_DRO] Re: Ball screw/nut repair

Can I ask what sort of price they charged.

I have seen quotes to regrind Bridgeport ones at £400 to £800

Always seemed a hell of a lot of money

Always been lucky and had good screws on everything I’ve aquired.

That's good to check. I agree, with .008" of play, the thrust bearing(s)
are almost certainly bad.

If you do need your ball screw reground, I've sent 4 ball screw assemblies
from my Fadal mills to Express Ball Screw Repair
(http://www.expressb <http://www.expressballscrewrepair.com>
allscrewrepair.com), and had good results. You might
want to give them a try. It's not an inexpensive process, but much less
expensive than buying new ball screws (at least for the Fadal mills).

I forgot to check the angular contact bearing when I had it apart. I
will check that Monday.
