Experimental Study of the Ultrahigh Speed Grinding Spindle System with a Squeeze Film Damper

In order to improve the attenuation ability of grinding wheel spindle and manufacturing quality of workpiece, an ultrahigh speed grinding spindle system with a SFD was designed based on the theory of squeeze film damping, and a series of experiments were done. 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 the speed of the grinding spindle is higher and the effect of attenuation of SFD to grinding spindle is better. Research works provides a new technology for the design of the ultrahigh speed grinding spindle system.
