Ruffel's cnc cutting journey

Yes I'm doing an mist system. I ordered two of these:

I did some googling and other people seem to have good luck with these aquarium air pumps. Most of them use the 80 l/min models but recommended going 120l/min +.
So I just got the biggest one. A compressor would be just to loud for my situation. And the paintbrush one's seem to have a hard time to keep up with the airflow.

If it does not work out than I will just return it in 14 days and get my money back. In that case a paintbrush / real compressor will be the alternative.
People who use compressors seem to be running these nozzles <1 bar so I think I'm alright.

As a liquid I'm testing lamp oil or ethanol , these both should work out fine.

The 280 l/min might be a bit much for my two little misting units , so it is possible that I need to add 2-3 more or just some copper to get some more volume trough it.

here is somebody running a 65-120l/min system:

Thank you for the recommendation. I will defiantly try it.

These look like the same at a third of the price.

Yeah I know. I just wanted to have it before the weekend.

The chips being cold is not a good thing. They should be so hot they hurt when they hit your skin and the part should be cool...

my legs are witness to that ...

Welcome back Dean!

Thanks Clive,
i have browsed and browsed but have not seen these

Then make something provisional. By the way a quiet airbrush compressor like mine 17l/min is enough when using the proper nozzle and making fine mist.

Much prefer mixing air with coolant as a cup of coolant could provide cutting all day long


here is my system:

On first video you could see the system and the damned mist when too much flow. Watch HD quality ant see how the light shows the mist in the air. What i am saying is it should not be like that cause after 5 min you could hardly breathe in the workshop.






On second video is properly tuned and spraying just the minimum. The air when thin is so strong that will blow crap from 20mm cutter from 20cm distance and clean properly before the cut . Plus no problem breathing in the workshop

Its my friend Jeff Potter. he happens to live nearby, we became friends from here, the forum. We are in his workshop making my Z. No idea where is he from exactly. On all pictures on Facebook he wears a red white vertical stripes T shirt, so he should be from somewhere there, i dont know the team name though...

I replaced the aquarium air pump with AS196 compressor with one paint/air gun.
When this all works out than I will make me a decent "fogbuster" setup.

The single flute VHM cutters also came in and they look really mean:

6 and 8mm

Around Friday / Saturday I'm able to start experimenting.
Again than you for all the help!
