Study on Squeeze Oil Film Damper in Ultrahigh Speed Grinding

The operation principle of SFD and the center moving orbit of grinding wheel spindle which under the operation of SFD are studied. Based on the theoretical research, the experiment is studied and analyzed. The study results show that the application of SFD technology can effectively restrain vibration which is caused by the imbalance quality when the grinding wheel spindle turning at ultrahigh speed. And it can remarkably improve the working quality and work efficiency of ultra high-speed grinder.
