Mist Cooling for Desktop CNC Boxford 160TCL lathe

[JohnnyK]

Glad I asked this question/ Thanks for your replies and the health safety warning as my workshop is small. I did have exposure to mist some years ago using my open VMC as you can't see it it so fine.
Paul I like the idea of a stepper motor powered peristaltic pump with a controlled drip rate. I will do some research to make up a small system. Do you use normal coolant mix or ethanol water?

Normal soluble oil and water at around 6% oil
When thread cutting I find some engine oil from the oil can works better than the coolant drip and as I don’t recover the coolant no issues with tramp oil
I made mine from mainly 3D printed parts three skate board roller bearings and a length of model aircraft silicon tubing plus a nema23 stepper I had lying around. Control was an eBay special rotary knob that generates step pulses and a £6 stepper driver. All working from 12v from the pc psu
