I use a vegetable based coolant and waylube from Oemeta. I have no idea where you can buy it, because they donate it to us. No smell, no growth, very irregular usage of the machines. The only difficulty I have is that the waylube gets a little sticky after sitting a few months, and the Z axis

THE best coolant to cut aluminum is WD-40. Bar none. I have never misted it but I used aerosol cans of it. Never a problem with a cloud of mist. The best flood coolant has been Hangsterfer's. Never an odor problem. Never a problem with separation while sitting unused. Just sayin Stuart On Thu,

I should note that while chips are found far from my machine as well, the mister barely leaves any liquid behind when properly adjusted. The only thing I don’t like about the old Bijur setup is that it does tend to vaporize some of it. But the Fog Buster is supposed to minimize that. When

In the toolroom where I work, we used to have Li'l Mister non pressurized reservoir misters. They caused a cloud in the room unpleasant to breath. We now use Fog Buster that uses a small amount of pressure in the feed bottle and it's much better for the surrounding air and much better to control.

Why not flood with neat cutting oil? It's a much nicer smell, although you do need to watch out for staining of close-fitting surfaces. I have serious doubts about the health hazard that a mist of any sort poses to the operator's respiratory system. Marcus
