Dynamic balancing is one of the key technologies in the realization of high-speed machining. In the field of grinding, some automatic balancers have been developed and manufactured. These balancers, however, will not be applied to high-speed spindles, because of their mechanisms. In the present paper, a basic mechanism of the balancer for high-speed cutting machines is proposed. That is, this balancer has four chambers on the periphery. Flow of compensating liquid from the center pocket to the chambers is controlled by the movement of an inner weight due to centrifugal force. A prototype is manufactured and the function of the proposed mechanism is evaluated. As the result of the tests, it is clarified that the balancing mechanism proposed in the present study is available for the use of high-speed spindles.
