The feed rate (speed at which the machine head moves in XYZ space) and the speed rate (number of revolutions per minute the cutting tool revolves around its axis) need to be proportional to each other, so as to have the machine cut out suitably sized chips. ### Calculating Jar and Jar Rolling Mill Speed Calculating how fast a Jar needs to spin is a little tricky, but simple one you know the factors. We need to know the inside diameter of the mill, that determine what speed we want, the outside diameter of the mill and the diameter of the rollers. ### Enter the measured mill rotation in revolutions per minute. Result 1 This mill would need to spin at RPM to be at 100% critical speed. Result 2 This mill's measured RPM is % of critical speed. ### Oct 19, 20060183;32;Congratulations on your ball mill You'll want to further reduce your motor speed by 31 to mill more efficiently.
