can calculate the rpm ball mill
Technical
Feed rate is calculated using the following equation: Feed = N x T x Z. N = number of cutting edges (flutes) T= chip load (chip per tooth) is the amount of material, which should be removed by each tooth of the cutter as it rotates and advances into the work. (mm per tooth) Z= RPM, the speed at which the cutter revolves in the spindle.
