Critical speed is the rpm at which the media will be stuck to the side of the jar based on centripetal force. All of the values in the formula are to be used in inches. I'm not sure how the 265.45 value is derived, but it is based upon inches. Critical speed = 265.45 / sqrt (jar ID - media diameter) Optimal speed is 65% of the critical speed.Ball Nose Finishing Mills Speed & Feed Calculator.
