Mill Coolant

Posted by / Uncategorized

One thing that I have struggled with as I’ve learned to machine aluminum is the appropriate settings for my mill. Too much speed with no feed and the aluminum gums up. Too much feed and no speed and the bit breaks. One thing that bigger mills often have is a coolant system. Some use flood coolant and other use mist coolant. One system that came heavily recommended was the “Fog Buster”. Apparently it squirts drops rather than atomizing the liquid. The advantage is that the mist doesn’t turn into a fog in the workshop, but its less messy than flood coolant.

Tonight I got the reservoir installed on my enclosure, the relay wired up to my cnc controller, and the nozzle mounted. I haven’t had a chance to test it, but I’m planning to in the next week!
