Once the machine has the information it needs, it'll spin the rotor until it finds the unbalance present. A rotor balancing machine determines the exact location and mass of the unbalance.After this, it'll mill or drill out a certain amount of material from the edge of the rotor which it identifies as the heavy position.

A high speed air compressor rotor weighs 7 lbs and operates at 55,000 rpm in the field. The user wanted to use the API 610 Balance Standard of 4W/N, where W represents the static journal load on each end in pounds and N represents the maximum continuous operating speed in RPM.
issue is that a rotor is fit for purpose. ISO standard 1940-1 (1986) outlines balance quality requirements and the permissible level of residual unbalance for various types of rigid rotor. 3. Field Balancing The following discussion assumes use of a rigid rotor (a rotor that operates below 70% of its critical speed). A flexible rotor (a rotor
