Kool Mist as cutting oil?

[bulgie]

One thing to keep in mind. Titanium has magnesium in it. If you have very fine chips watch out for them starting a fire. Koolmist has water in it. Not a good mixture. Be sure to have a fire extinguisher handy.
I speak from experience.

What Ti alloy has Mg in it? The alloys I work with, 3Al/2.5V and 6Al/4V, are mostly Ti of course with some aluminum and vanadium, but no Mg, except possibly as an impurity. Grades 1 thru 4 are nearly pure Ti ("Commercially" Pure or CP) just varying in how much Oxygen is allowed.

But your point about finely divided Ti chips being able to burn is true; pure Ti or common alloys can burn in air if the chips are fine enough. No Mg required.

I googled can it burn and google agrees with me.
And you tube will show you how dangerous it is.
Bet I have seen it burn at least 20 times.
Google is it dangerous. I try to warn people about what I seen in my 70 years of machining.
