Hey everyone, I’m relatively new to cutting aluminum with my Lowrider v4, and I just realized how exhausting it can be to constantly babysit a CNC router while using a spray bottle for coolant—especially during a one-hour cut. How would you guys recommend setting up a mist coolant system?
If you’ve got compressed air, maybe something like this:

And you could automate it by adding a simple solenoid valve to your air supply.
That said, I don’t actually have any experience using a system like this so, I’ll be interested to see what other, more experienced people have to say.

Most of us, including me 
use trochoidal cuts. Depends on what you are doing though.
Wait, so I don’t need coolant on trochoidal cuts.

That is why it was developed. It prevent heat build by limiting engagement. Depending on what u are doing you should not. Cutting my lr4 parts went great, even though I had printed plates in!
Chip load is lower so less change of chips welding themselves to the bit.
All the cuts in the thread I linked were done with no cooling of any kind.
Oh, that makes sense! Thanks for the help!
I still used mist even when using trochoidal. I found that I was still getting some chip welding without
