RE: [CAD_CAM_EDM_DRO] Bridgeport mill ballscrew conversion

Ron,

Thanks for the good advice (feeling better already). Do you
know of a good distributor? I don't think they sell direct
if I remember their website correctly.

This will be my first step, then it's what servos, etc.
With great guys like you, I'll save a lot of $$ and time :)

Thanks again,

George

Sure they are. That is per foot and its a tolerance not a guarantee to
be out that much. I need to get out some ground standards and check
these that I have. I'm thinking there isn't going to be much of an
error. If they touted .001" error tolerance per foot, nobody would buy
the ground screws that they sell also. Alot of companies market things
that way. Even if they are out that much over a foot. Divide that by 12
and thats how much they'll be out in an inch, if the accumaltive error
is consistent throughout 12". .00025" error in an inch is more than any
Bridgeport could hope to hold anyway with cutter deflection etc. They
are good screws for a Bridgeport.
