摘　　要：对超精密车床主轴回转误差测量过程中标准球的安装偏心和传感器的安装偏心对误差分离的影响进行了深入研究。详细分析了标准球和传感器安装偏心的产生过程和原理,并设计了可以精确调节标准球和传感器位置来调整偏心的装置,提出了一种简单可行的偏心消除方法,可将标准球的偏心降到0.9μm以下,传感器的偏心降到10μm以下。采用双向测量法对超精密车床主轴进行测量,并用多步法将测量数据中的圆度误差和回转误差进行分离,最后进行实验验证,为该方法提供实验依据。The influence of the eccentricity of the standard ball and the eccentricity of the sensor on the error separation during the measurement of the spindle rotation error of the ultra precision lathe are studied in depth.This paper analyzes the generation process and principle of standard ball and sensor installation eccentricity,and designs a device that can adjust the standard ball and sensor position accurately to adjust the eccentricity.A simple and feasible eccentric elimination method is proposed,which can reduce the eccentricity of the standard ball To 0.9μm below the sensor eccentric drop to 10μm below.The two-way measurement method is used to measure the spindle of the ultra-precision lathe,and the roundness error and the rotation error in the measured data are separated by the multi-step method.Finally,the experiment is verified and the experimental basis is provided.
