I typically apply cutting oil by hand, and water soluble by a flood
blast from a pump.-a (more or less)
Whenever I see a video of somebody using one of those old smaller turret lathes I watch.-a Slowly I've been piecing together everything I need to know to set up a job on mine.
Recently I watched a video and the operator was using pumped flood oil.
It wasn't the blast of nozzles I use with water soluble coolant on the
CNC mills, but it was a solid continuous stream.
I typically don't use flood on the lathe because I don't like being
soaked by coolant, but this was controlled and the oil did not seem to
be slung off like a water based cutting fluid.-a The other reason I don't often use flood on the lathe is the coolant evaporates just sitting
there.-a I use my bigger lathe mostly for repair work.-a-a I use manually applied cutting fluids on the big manual mill for the same reason.
The coolant disappears, even though I do use it a lot more than the
lathe for roughing mold blanks to size.-a Neither gets used for many production jobs.
I'd like to hear your experiences and observations.-a If oil stays on the work better, and it doesn't evaporate (not at the same rate as water
anyway) it could be an answer for lathe work.
I'd not have a problem dumping several gallons of relatively expensive cutting oil into the lathes (after cleaning them out) if it would reduce some of the headaches of cutting fluid on those machines.-a They both
have tanks and pumps in their respective base.-a Maybe not the mill I use
it at speeds and feeds that sling chips yards (meters), not inches (centimeters).

-a The only times I use lube of any kind on the lathe is parting and threading , and both get oil based cutting fluid . I occasionally
dribble a little ATF on the mill while facing aluminum .
