Mist Coolant Project

[routercnc]

I've been playing with various solutions to combine air and lube/coolant and have been having some success with gravity feeding the lube using a drip style machine oiler.
With the lube delivered at the air nozzle there is negligible airborne droplet creation but it's a bit of a pain to get the feed exactly right.

This is my latest metering system, now I just need to case the PSU and build the new nozzle system.

Interesting. I was considering how best to do mist coolant so will watch this post. Best option to me seemed to be the pressurised coolant tank arrangement when the coolant is forced into the air flow under pressure rather than drawing it Venturi style with a partial vacuum which I guess this is similar to. But I don’t have an air compressor so no rush to go any route just yet.
