just want a nice finish, yes, the servo amplifier and the servo motor
with built-in tach would be sufficient.

What I really want is to be able to adjust the feed with the turn of a
dial. Fast feed for roughing: too slow? - turn it up. Slow feed for
finish: still too rough? - turn it down some more. I have this with
VFD's on my drill press & lathe spindle and I've gotten spoiled by it.


Ive got it on the feed motor of my Hardinge HLV-H

Its soon to have a twin....$1500

"I am for doing good to the poor, but I differ in opinion of the
means. I think the best way of doing good to the poor, is not
making them easy in poverty, but leading or driving them out of
it. In my youth I travelled much, and I observed in different
countries, that the more public provisions were made for the
poor the less they provided for themselves, and of course became
poorer. And, on the contrary, the less was done for them, the
more they did for themselves, and became richer." -- Benjamin
Franklin, /The Encouragement of Idleness/, 1766
