### Speeds and Feeds 101

With miniature tooling and/or certain materials the speed calculation sometimes yields an unrealistic spindle speed. For example, a .047" cutter in 6061 aluminum (SFM 1,000) would return a speed of ~81,000 RPM. Since this speed is only attainable with high speed air spindles, the full SFM of 1,000 may not be achievable.

### Ball mil design calculation?

31-3-2008The critical speed (rpm) is given by: nC = 42.29/√d, where d is the internal diameter in metres. Ball mills are normally operated at around 75% of critical speed, so a mill with diameter 5 metres will turn at around 14 rpm. The mill is usually divided into at least two chambers, allowing the use of different sizes of grinding media.
