Hi,

Has anyone here got any experience using ethanol delivered via a mister system when high-speed cutting aluminium? I understand that's what Datron use in their machines. At the moment I'm using WD40 which works but makes a horrible sticky mess when mixed with aluminium chips/dust and tends to stink the workshop out. I also have issues with the WD40 separating in the mister reservoir (the bottom of the tank ends up with white fluffy looking stuff floating around in it).

Are ethanol fumes an issue? Where can I economically source ethanol, in appropriate form, a few litres at a time? So far I've only been able to find bioethanol (the purity of which I'm unsure about) and methylated spirits (which probably smells worse than WD40) in bulk.

Cheers,
Matt.
