摘　　要：对精密、超精密气体静压主轴回转精度测试现状进行概述。介绍自主设计的一种气体静压主轴回转精度测试平台,该平台主要包括测试平板、调心组件、柔性联轴器、位移传感器、标准球和电机等,并说明测试平台的组成、结构设计及测试实例。设计的气体静压主轴回转精度测试平台,为解决不带驱动及编码器精密、超精密主轴的回转精度测试提供了参考。The present situation of high-precision aerostatic spindle rotation accuracy testing was summarized. The test-bed for aerostatic spindle rotation accuracy which was independently designed was introduced. The test-bed comprised test-table,self-aligning components,flexible coupling,displacement sensor,master ball and motor. Then the test-bed＇s composition,structure and test method were introduced. The designed test-bed provides a reference for high-precision aerostatic spindle rotation accuracy testing without drive or encoder.
