摘要
从主轴回转轴线定义出发，阐述了轴线误差运动形式和回转精度的测量方法。在测量结果评定基础上，分析了测试过程中几个重要的测试条件对测试结果的影响。
Proceed from the definition of the rotating axis of the lathe, the author described a pattern of axis′ kinematic accuracy and the methods measuring the rotating accuracy. Based on the eveluation of the results measured, the influences of several principal measuring conditions on the results measured during measuring were analyzed, which improves the reliability of results measured to the rotating accuracy of the spindle.
