Technical Manual Frequently Asked Questions (7. Frequently Asked Questions — continued) What is Mechanical Advantage? Mechanical advantage is the ratio of the clamping force divided by the lockrod force. Where (f) is the lockrod force and (F) is the clamping force. Within the KM4X™ system, there are 3 inclined planes (angles): the lockrod angle, the canister angle, and the tool angle. Technical Manual What is the maximum coolant volume flow? Using the equation below for volume flow and assuming a flow factor of 0.6 for an orifice, the table below can provide a rough estimate of maximum coolant flow (L/min). Q = d2 * 3P * 0.659 * f Pressure (bar) System Size Diameter (mm) 50 100 150 200 250 KM4X63 7 137 194 237 274 306 KM4X100 10 280 395 484 559 625 KM4X125 16 716 1012 1240 1432 1600 NOTE: These values are based on coolant diameter through the lockrod. Could the maximum permissible contact pressure of the material be exceeded through the high clamping forces? Based upon extensive calculations, the operating stresses for KM4X™ are well within the permissible limits.
