Mill Upgrades – Flood Coolant Part 1

I’m trying to wrap up the documentation for the spindle belt upgrade so I can get it up on wcubed.co, and since spring has sprung I’m also pretty busy getting the yard in order. I did find some time to work on adding flood coolant and tying in the air blast delivery to it.

I’m using a Brute 20 gallon tank with some prospecting sifting screens, and the original 4 GPM coolant pump mounted on a polycarbonate stand to keep it above the coolant level. The manifold is from Automation Direct, and the hoses are standard Loc-Line (one 3/8″ NPT that came with the mill, the rest are 1/4″ NPT). The system is waiting on me to make a drain from the stand into the filters on the coolant tank.

I also have a new drag chain waiting to be installed, which is large enough to carry the coolant line. The Z-axis end stop sensor wire needs to be run down that, as well as the motor cable and the lines mist coolant and air blast, so it should help tidy things up a bit.

Bonus picture: when you have to tap some M3 holes but don’t have a tap holder small enough, a TTS ER20 holder can come in handy.
