ABSTRACT:
An unbalance correction system is disclosed for balancing a workpiece while it rotates in a conventional balancing machine. Stock removal occurs simultaneously with unbalance measurement. State of balance is continuously monitored while correction proceeds. The trial and error aspect in conventional methods of alternating between measurement and correction operations is eliminated, resulting in a higher precision balance in reduced procedure time. Stock is removed by discharging capacitors across a gap formed between the spinning workpiece and stationary electrodes. The momentary high-current arc melts and vaporizes material during only a portion of a total revolution. The discharge is triggered by a vibration induced signal from the balancing machine when the heavy spot is adjacent the electrodes.
