In order to reduce rotor vibration, a smart spindle with real-time balancing mechanism using magnetic fluid is proposed in this study. The magnetic fluid is enclosed in the spindle, and the distribution of the circumferential mass is controlled dynamically. In this paper, the characteristics of various kinds of magnetic fluid have been examined. The suitable results for the smart balancing mechanism were obtained. A test spindle for verifying the expected effects of the real-time balancing mechanism was designed and developed in order to evaluate the control method of the magnetic fluid experimentally and to accumulate adequate information for the basic design of a machine tool spindle. Moreover, the testing spindle was modeled and simulated using a software package to estimate the rotor vibration.
