We regularly cut 6061 aluminum with our mini CNC mills. Both are Sherline mills modified for educational use (one is a Denford, the other is a Intellitek spectraLIGHT). The trick is to know what the machine limits are, and to use sharp, high quality carbide tooling. Last Saturday I used one to drill the bolt circle patterns for the sprockets on the sides of the timing belt pulleys for our treads.
When they're the only machine shop you have, it's amazing what you will figure out to use them for
