Any advice, rules of thumb, tables for calculating cutting coolant flow?
Links to web pages would be appreciated.

I'm designing a coolant pump and associated delivery system to be used
for a small benchtop lathe and a mini mill. Starting with actual flow
numbers would be nice.

The best flow varies with what you are doing. For the lathe, I built a system
pot of a manifold, a bunch of cheap needle valves (one to a nozzle port), plus a
feedline ball valve (to turn the flow on and off without disturbing the
needle-valve adjustments). It works well, but you still need splash shields to
contain the mess.

As for the mill, two nozzles would be best, on opposite sides to the cutter, but
again a needle valve is useful, as quarter-turn valves are hard to adjust
precisely.
