Haas Automatic Coolant Shut-off!

No one likes taking coolant to the face!

To hose down the machine, the coolant has to be turned on (obviously) but when it’s on, it comes out of the spindle ring, which makes for a nice ricochet, if you know what I mean. We came up with a solution to make life a little more convenient. When the machine is at it’s home position, we don’t need coolant, so let’s machine some brackets on the Tormach, add a switch, and a solenoid to make an automatic coolant shut off!
