Apr 22, 2019· The max depth you should use in a slot cut is the diameter of the end mill, so for a 1/4" OD end mill, you can cut 1/4" deep at a time. If you need to go deeper then make multiple passes. The max axial depth of cut, meaning the max amount of the end mill that is touching the work when doing profiling cuts, is 1-1/2 the diameter of the end mill.

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 (although this depends upon feed input size - mills including a roller press are mostly single-chambered), allowing the use of different sizes of grinding media.
