DIY MQL (minimum quantity lubrication; no fog or mist)

Nice system. Where did you get the clips that hold the tubes together? Also, what psi are you running? Thanks!

I converted one of those to fogless as well. One thing that hinders the adjustment is that almost all of those things have Out valves, not in. So in essence the valve is being used backwards and doesn't actually regulate well. In valves are harder to find but are out there.

What lubricant are you using?

You got the ratio of liquid way too low there. For steel you need a bit more. Aluminium its fine to have a very light spray.

i can’t find any info on mql fluids, coolant vs lubricant…….. any idea where I can learn more? goal is to keep my turning parts from getting as hot as they do and having to wait for them to cool to measure. rust is not an option. do you run oil,? seems most kits include or offer cutting oil for this kinda thing
