Magnesium Cutting Fluid

[C JAYNES]

I have to machine a lot of magnesium, and I am looking for some advice on cutting fluid. I will cutting it in a Haas VF3. I am concerned about using water based cutting fluid.

Any ideas?

 

Thanks

Do a forum and web search, staying away from waterbased

is prolly best.

I remember back in the day when i started a company i

worked for used "lard oil:", i think thats what it was.

Im sure theres lots of new coolants. I can find you something if you like.

Magnesium is fun to machine,sure there is a slight chance of a fire,but it's very slight.

Make sure that you have the correct fire extinguisher handy,I think a class D.

 

As for coolant,hmmm I think you need an oil based coolant.

and SHARP TOOLING!!!!

if your tool gets dull, watch out for the little white spark that will be flying off into the chip pan.

I have used water based coolent on it while cutting Valve Covers for High performance Motors, (funny cars, dragsters) worked for me,

 

PS,. do not let it spark at all, I have seen it start on fire just by cutting it on band saws, use oil dry to put it out with, not WATER. the whole idea is not to cut it at a high speed that will make it burn up hehe, GL (I always cut it at a low RPM) better safe then sorry you know.

I've used the vegetable based oil products in a mister type set-up,trico or uni-mist sprayers

Whenever our guys cutting magnesium, they never use coolant.
