Hey guys, I've got a quick question for you regarding milling aluminum. I'm wondering if it is ok to machine aluminum with no coolant, keeping high-pressure airflow on the cutting bit instead. I understand the need for coolant to keep the bit and stock clear of debris and to prevent overheating, and the few runs I have made with the air seem to work fine. I suppose I was just wondering if there is any other considerations that would lend itself to using coolant over air. As I’m sure this is critical, I’ll be machining almost exclusively aluminum and other soft metals, generally at a low feed rate (2-6in/min) and at relatively low rpm’s (1500rpm). Thanks.
