I personally disagree with bashing of flood coolant as used on
lathes. (and, granted, I do not have much experience).

First, with reasonable speeds, flood coolant is not being sprayed
around by rotating parts that are being turned. Not enough centripetal
force, at speeds that seem reasonable to me. The only way it would get
sprayed around, for me, is if it would find its way on the chuck
itself, as in turning near the chuck.

Iggy, if you're not turning fast enough for that coolant to fling half
way across the shop floor, you aren't turning fast enough to justify
water-miscable coolant.

Sorry Ed, that just isn't true.

I agree.. Coolant offers temperature control, which, in turn, offers the
ability to better control finished sizes, to say nothing of improved surface
finishes. Coolant can be a very valuable asset on most any machine. You
have to balance the inconvenience of the coolant against the benefits. It
is often a win/win proposition. A good example would be in roughing
stainless, where heat is a serious issue.
