On my CNC machine, I don't have a mill.

I used to cut squirting with Industrial WD40 type stuff called workmate 40(WM40. .:naughty:) that I have manufactured and sell in my day job.
This was ok but has the negative affect (like you'll know) of making the chips stick and clog the slot rather than fly away. . . this has 2 negative affect's.(Other than fumes)
1: The heat doesn't leave with the chip.
2: The fluid heats because it's not flooded away so just sits there boiling.
Both together heat the Ali so the chips are warm before the cutter actually cut's, on cheap Ali or if too hot can cause sticky bits or chips which weld them selfs onto cutters.

The best by far is blown air because it keeps all the slot clear and blows the chips away from in front of the cutters path. Thou like I say messy as hell with chips blown all over the place. . . . There's a 10feet perimeter round my machine that looks like it's rained glitter when doing big job's.:lol:

Tried using a mister but I couldn't breath so soon knocked that in the head.

At the minute I've just got 3 simple coolant nozzels connected to regulator pointed at the cutter blasting away all in it's path (Got big compressor)

When I get time(So never) I'm going to make Ali ring sandwich with 8 short directional squirt nozzles, 4 will be air, 4 coolant that fasten to the base of the spindle (Maybe put in some Led's for light as well) then with selonoid's control both with Mach3.
Air will be constant but turned on off by Mach and coolant will squirt every so often just enough to stop sticking but not fume me out the shop like mister.
