Abstract
It is important to reduce the run-out of the spindle for high speed machining centers due to the centrifugal force in order to get high machining performance. In this study, the balancing technique of the high-speed spindle is investigated. In the experiment, two displacement sensors are used to detect the run-out of the spindle and those outputs are analyzed through an FFT analyzer. The amplitude and phase of the run-out are measured. From these results, we can reduce both of run-out and vibration.
