Greetings all; I just found the only way to cut this panel alu is to keep the tool cold with a blast of air at around 125 psi blowing on the nut and tool.
Anything less and the heat telegraphing down the tool from the motors front bearing, combined with the alox formation and friction gets the tool so hot it burns the cutting oil away and welds the alu into the flutes of a 4mm coated SC tool. Hell to pick it out. So my thinking is to give the bottom of the bed a coat of sealer, jack up the rear of the bed about an inch so liquid coolant running off the work will drain down the t slots to the front of the machine and be caught in a miniature rain gutter, where it will be delivered to a holding tank identical to the motor coolant tank, with a similar aquarium pump in the bottom but with the return being filtered by dumping the return onto a cloth filter to keep the bigger stuff out of the tank. I've got almost everything but the last 8" of bendable delivery stuff with a nozzle on the end of it. Amazon has those cheap enough. Old, used oxygen hose from the missuses oxy generator could supply adequate hoseing I think except for the bigger bore drain. It could be threaded thru the cable chain to the motor, keeping it out of the way. 3 or 4 gallons of distilled ought to be enough. I've 3 gallons of distilled in the motor coolant system, and seems to hold at 35C just from the pumps heat. Does it sound serviceable to you folks? Better ideas maybe?
