I use coolant and a time air valve setup that blows every few seconds. My table is enclosed partly keeps 90% of the coolant in and flowing back to the tank. Air keeps the chips from building up. With out coolant heavy cuts are impossible even with the best tools. To much heat and the tool just starts melting the aluminum rather then cutting it and eventually just breaking the tool if lucky. Worse case on a cnc is blowing the coupler or stepper. (i've done both)
