Ethanol mist for cutting aluminium

[matt-b2]

He certainly seems to be pushing that endmill pretty hard - Not sure my spindle/steppers would be up to that although I think I can push them a lot harder than I currently do.

In the next couple of weeks, I'll find some time to stick a block of 6082-T6 on my machine and play with the cutting parameters - I've done that in the past to land on a set of figures that work okay with plenty of coolant. I think it is time to revisit the experiment with an aim to push my machine harder both with and without coolant.

I'd quite like to experiment with different endmill geometries too (i.e. number of flutes), but I haven't got the cash to be forking out on loads of different endmills right now, so I'm probably stuck testing with 2-flute tools.

Carbide 2 flute seem to work great for alu in my experience. With or without coolant..

I'd like to revive this slightly old thread.

I have flood on my Triac, it works well but I had the residue / mess it leaves over time.

Id love to cut dry if possible. Since I've upgraded to a 1.5 KW AC Servo Spindle, I may also take some test cuts with smaller (read, cheaper) endmills and see what I can do before I break them.

How do Datron manage with Ethanol cutting without the health / risks?

Extraction, extraction and some more extraction ;-)

So in a home / garage environment, Ill need to build something for this? Not sure what the costs / technicalities are for this.

I could continue to do Flood on my Triac however my new machine will not have Flood, well, not planned for. I may reconsider this.

Cold air needs too much air, Ive looked at this before. I dont think its a DIY option.

So Id like to know what options we have for 100% dry cutting. Clearly its possible .....?

Even if cutting dry you will need to move chips and vacuum isn't even close to air for getting chips out of the way in holes and slots, so why not look at something like Boyan's solution to add a little lube to your air, then you can use a good bathroom extractor to keep the mist from filling the workshop,

With mist and fumes collector and filtration

PS. If you do it properly similar to mine, it DOES NOT mist. It spits small droplets, not mist. Thats why its called Foggless

Thanks, can you link the one you use please? I recall you made your own?
