How much to rebuild series 2 ball screws?

[camarogod98]

Ive got a bridgeport machine with the cnc series 2 iron. its got to much lash in X and Y to make a good finish on parts. Does anybody know how much it would cost to get them redone ( I am assuming reground and balled)and where a good place to get it done would be.

Don't know the answer but here are two places that have come up before which I noted:

I gather these kind of places will inspect the assembly and tell you what it needs. rbc says 10-30% of new price to reball, 30-50% to regrind screw.

If you find out, let us know here. I may have to do that one of these days.

Be sure it is not just the thrust bearings. If the screws are not LOUD I would first suspect the bearings.. I replace the y on one of my machines, and it was fine.
