Will de-methed glycerin work as a machine tool lubricant?

I thought I read a while back that you can use glycerin for a light cutting/milling fluid.

Is this true? I'd also like to know if I can use this stuff for cutting threads in say a pipe threading machine.

Thoughts? Experiences?

Thanks.

Hmmm, that's an interesting question...
Glycerin has a characteristic (its solubility in water) that'd make it suitable as a machining lube.
Also, we all know it's slippery (or at least, those of us who ever stepped on some glycerin on the floor... Big Grin), so...
It should be interesting to try.

I'm really concerned about flammability under heavy machine tool operation. I know that machine tool oil can get quite hot especially with certain gear cutting operations.

Yeah, that would ruin your day kinda quick...
However, if I understand this correctly (and there's no warranty I actually do), the byproduct is more like an unfinished soap than pure glycerin, and soap is not flammable (I hope Eek)
Anyways, the best way to find out is trying it...

I would try it... And berny is correct. The glycerin byproduct is really a "bad" batch of soap. It would be just as accurate to call it soap. It can be 50% or more soap depending on the oil and water you are starting with.

The guys from Arbor Biofuels use BD as a cutting lube for some of their fabrication. Might ask them for some details on that.

Am I? Hmmm, I guess I'm better at guessing than I thought... That's nice to know.

BD as cutting lube? Eek
No, I'm not that brave...

I have seen glycerine/water used as a hydraulic fluid with good results. The system was 30 years old and the pump was fine. Something must have been acting as a lubricant.
That was however pure glycerine not the gunk we get.

Axle grease is soap made with calcium or lithium lye, so soap should have similar properties.

There's a company in Natal (South Africa) which sells cutting fluid made from crude glyc. Not sure about the process though. A friend tried some diluted with water for thread cutting on a lathe and it seemed OK.
p.s. For pipe threading machines, the best lube is lard. I keep a bucket of used stuff beside my machine.
