Re: [CAD_CAM_EDM_DRO] Making your own Ball nuts

Well, thanks for the complement Marv!

Yes I think the cast polymer nut could work for acme as
well as ballscrew material with the right o.d. clearance.
Acme of course is not really the best for preloading
but it can be done. It would have to be free of wear
as well.

Another thing that might be economical is just buy the
ballscrew material without a nut- the nut is often most of the
cost anyway. Then cast a polymer nut around it.

If anyone is seriously interested in doing this I could talk
to the Philly Resins product manager about the technique.
I am afiliated with parent company of Philly and know
some of those guys from corporate meetings. I will be back
and forth to there as I am designing an encoder for another
division.

They seem to really know their stuff.
