摘　　要：高速主轴的回转误差运动直接影响到被加工零件的加工精度与产品的使用寿命。为了对数控机床的加工性能进行合理评价,分析了同步径向误差运动与工件圆度以及异步误差运动与工件表面粗糙度之间的关系,并采用美国Lion Precision公司开发的主轴误差分析仪对某型数控机床的主轴系统进行回转误差及漂移的测量,根据测量结果对所测主轴加工性能进行评价,为实际生产加工提供了参考。The rotary error motion of high speed spindle affects directly the processed workpiece machining precision and product service life. In order to reasonably estimate machining performance of the NC machine tool, the relationship not only between synchro- nous radial error motion and part roundness, but also asynchronous error motion and surface roughness were analyzed. The rotary error and shift for a certain type of spindle of NC machine tool were measured by using the ＂Spindle Error Analyzer＂ developed by Lion Pre- cision Company of the USA. The spindle machining performance is estimated according to the measuring result, which provides refer- ence for practical machining in production.
