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.

Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.

The speed at which the piece advances through the cutter is called feed rate, or just feed; it is most often measured as distance per time (inches per minute [in/min or ipm] or millimeters per minute [mm/min]), although distance per revolution or per cutter tooth are also sometimes used. There are two major classes of milling process:
