A little throwback to a 2011 customer YouTube video.... Below are excepts from the a thread on Practical Machinist talking about it.
"So I'm at my buddy's shop Saturday morning and I tell him about a recent thread on this board about machining aluminum dry. He asks me what I think the upper limits are for doing this and glancing over at his pretty Doosan VMC I reply "Let's find out".
I knew I was gonna get beat up pretty bad shooting video from this angle so I fashioned a bandanna from shop rags, wore gloves, glasses, and yes.. even cut a hole in a garbage bag and wore it with pride.
Anyway, here is what .036 per rev with a 1/2" tool looks like. The tool could take more but the spindle was at 133%.
No wimpy chips."
