Excel speed/feed calculators for Ball Nose Finishers, 90Degree Square Shoulder Mills and Toroid Cutters. Common formulas to help calculate RPM, SFM, IPM, IPT and MRR for milling.
Mar 31, 2008· The critical speed (rpm) is given by: nC = /√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.
Milling Speed and Feed Calculator Our free speed and feed calculator can be used to determine the spindle speed (RPM) and feed rate (IPM) for the specified cutting conditions, as well as the cut time for a given cut length.
