顶尖支承件检测精度的分析

Analysis on Tested Accuracy of Centers Supported Workpiece

分析了用顶尖支承回转工件的圆度及国跳动的检测精度，着重分析了顶尖支承回转轴线的径向回转误差对圆度及径向圆跳动检测精度不可忽视的影响，指出应控制该回转误差以保证圆度及径向国跳动的检测精度。

An analysis is made on tested accuracies of roundness and runout of the rotary workpieces supported between centers. There many factors that effected on the tested accuracies of the workpiece. Here,the analysis is made mainly on influence of radial rotating error of the rotation center line between the supporting centers on the tested accuracies of roundnessand runout. The influence can not be irnored. The rotating error should be controlled to improve the testedaccuracies of the roundness and the runout.
