I’m and engineer, hence my complicated way of doing simple things
Here’s my revised Mist Coolant System, I really like how this is working out.
The diagram below speaks pretty much for itself. I am using a cheap Mist Generator from Amazon, common water filter as the coolant reservoir, combo air regulator and oiler and a 115VAC air solenoid valve with a remotely located switch.
Impossible to get “Cool Mist” or some such here in Trinidad and forget about trying to import it, so I have to resort to my own concoctions and the following is working well for me.
~30% Water Soluble cutting oil
~65% Distilled Water
~5% Isopropyl Alcohol
The mixture forms a light emulsion but over time it tends to separate with the heavier stuff settling at the bottom of the reservoir, hence the small aquarium air pump to keep things agitated/aerated and in suspension.
The rig is plugged into the switched outlets at the back of my mill.
The oil/water is a typical dilution albeit on the oil-rich side and the small quantity of alcohol creates a very low temperature when the mist leaves the nozzle.
The coconut oil in the oiler was left over from when I used coconut oil and pure alcohol in the reservoir for cutting non ferrous material. But fearing an explosion hazard, I have refined the system to this variant. I find this now works very well for both ferrous and non-ferrous cooling/lubrication when cutting.
