Tim,
I presently have no $ invested in any equipment other than the mill.
Why would the servo/G320 scenario be better for me.

Sounds like I was thinking of someone else's project. Seems to me the
sizes I have heard used successfully with a mill that size is 800+
in/oz. I would probably want to use about an 1100 in/oz motor or bigger.
Definitely in the range where if you don't have money invested in motors
or drives you are likely to get by for less and get better performance
by going with servos and Gecko G320/340 drives.

Tim,
I guess it's my engineering background that makes me
want to plug all the components into a formula, and come out
with an exact answer. The mill I'm going to convert, is a
full size Enco, about the size of a Bridgeport, 1 1/2 HP
variable speed motor, 8" X 36" table, and driven by a VFD.
I'd rather oversize the motors, and have some torque to
spare, but I was just trying to save a little space on the
quill feed, by using a slightly smaller motor. Thanks for the
direction.
