CNC Lathe cutting oil vs Water-sol coolant?

[Capntom]

My company has just purchased a Citizen L20 CNC Lathe for small parts. We spec'd a High pressure "cool Blaster" oil delivery coolant system with a "mist collection system".

I have been out of machining for a few years and thought the trends were going towards Water-sol type coolants, any thoughts?

It's been years since I've use oil coolant. I just know its much better on the machine. Probably don't get the bacteria growth either. If the mist collection works correctly there shouldn't be alot of coolant loss that way either. I hate all these water mix coolants especially the synthetics, some are down right hazzardous.

We use a synthetic coolant that is safe and does not smoke as much as oil based products. In our 15” chuck turning center, drilling with a 2 7/8” insert drill in alloy steel requires low smoke coolant.

Generally speaking using water soluble fluids allows you to run faster and produce more parts per unit time than running with straight oil. With your high pressure high volume fluid delivery system you are going to atomize the oil and set up the potential of a spark spoiling your productivity -- yes I know that there are synthetic oils that have very high flash points but unless the tooling or material drive you to that it will not be cost effective. In general the faster you go and the harder your materials are the more effective fluids with high cooling are at low SFPM and with soft gummy materials fluids with higher mechanical (more oil like higher concentrations in soluble oils) work better.
