How to Machine Aluminum: All You Need to Know
Lots of guys simply go with 1000 SFM to calculate their RPM. If you do this, you're really not going any faster than everyone else. To be honest, this is usually is what's recommended for most cutters. 1000-1500 SFM is a totally normal speed to run your spindle at. With harmonic testing, though, you can hit 3x this speed. More on that later.
