Technical Information K XKENNAMEUL Balancing Balancing (continued) The permissible residual unbalance can be calculated by the following equation: F = U x (n/9,549)2 (Newtons) Where: U = unbalance in gram millimeters (gmm) N = rotational speed (RPM) In this particular case, the unbalanced induced force would be Good balancing quality does not necessarily guarantee safe operation F = 1 x (25,000/9,549)2 = 6,9 N. The cutting forces generated at higher speeds. Other variables (spindle connection, type of operation, are likely to be orders of magnitude greater than that. cutting parameters, machine stiffness, bearing condition, etc.) should always be considered. Unbalance can be corrected by material removal (drilling, milling, grinding), For a given unbalance, the following formula can be used to determine material addition (set screws), and material redistribution (balancing rings the hole depth (L) necessary to correct for the unbalance : or set screws).
