  • Balancing and RPM - Sandvik Coromant

    Balancing is a procedure in which the mass distribution of a rotor is checked and, if necessary, adjusted. This is done to ensure that the unbalance force acting on the spindle bearings at the service speed is within the bearings' capacity. The vibration of the journals is also controlled so that it is within the specified frequency limits.
