Re: re:Lathe Rack & pinion.

Smoke,

Yes. In a low cost CNC lathe the "feed","lead", and ballscrew are all
the same thing. The ability of CNC to move slowly, precisely as well
as rapid moves (large dynamic range) allows this. Also, for steppers
at least, the inverse relationship between load and speed required
for turning. (rapids at low force, feeds at (relatively) low speed
with high force)

Hope this helps.
