摘　　要：针对HCM-Ⅰ型超精密车床,进行了主轴轴向振动随电机转速变化规律的实验研究,不同转速下主轴轴向振动信号的傅立叶(FFT)谱表明,主轴系统与电机同频振动,在转速为700～800r/min时振动最大,该转速范围之外的主轴轴向振动幅值随转速的提高而增大。Through a series of trial on HCM-Iultraprecision turning machine, t he variation trend of spindle axial vibration with rotational speed is investiga ted. The FFT power spectra of spindle axial vibration show that the vibration fr equency in spindle system is as same as in rotor, and the deteriorative maximum vibration happens at the rotational speed of 700～800r/min.The axial vibration a mplitude increases with the increase of rotational speed.
