Apr 15, 2014· Milling Aluminum So I know this topic comes up a lot but I'm still confused. My question regards cutting feeds and speeds in 6061 and 7075 aluminum. the majority of our machining is done on a Haas Mini Mill. During roughing i have an rpm of 2400 and a feerate of 11 (guessing its inches per minute). Now that gives me a chip load of 0.0011.

Feb 09, 2007· At work we run aluminum at very high R.P.M. I've run big diameter parts at two thousand feet per minute, which is actually a slow R.P.M. due to the diameter and on the next machine run a small end mill at the machines maximum R.P.M. of 12,000. But when I go out to the garage and use my mini mill and the lathe, the top R.P.M. is limited.
