Analysis about Vibration and Noise of Ceramic Electrical Spindle
High speed machining (HSM) technology is used in a broad range of applications to machine ferrous metals and nonmetallic material. The electrical spindle is one of the major elements to keep the machine running at high productivity. In recently years, the requirement of rotational speed and rigidity of electrical spindle is getting higher and higher in order to satisfy the high speed processing. So a high speed grinding electrical spindle equipped with hot isostatic pressed silicon nitride (HIPSN) fully-ceramic ball bearings without inner rings and yttria partially stabilized tetragonal zirconia polycrystal (Y-TZP) ceramic spindle shaft is designed for higher speed and rigidity. Because the processing precision is relevant to the vibration of electrical spindle, it is necessary the vibration and noise of the ceramic electrical spindle is detected. This paper presents results of vibration and noise of the ceramic electrical spindle and analysis the reason of phenomenon. The analysis shows the vibration and noise of the ceramic electrical spindle is up to the standard.
