摘　　要：为提高数控磨床的磨削性能,应用美国Lion Precision公司生产的主轴回转精度测试仪,对一台高效精密数控磨床砂轮动静压主轴系统的回转精度进行测试,结果表明该砂轮主轴系统的回转精度较高。综合主轴的旋转精度、静刚性、抗振性、热稳定性研究结果,可以验证该磨床砂轮主轴的性能较为优良。The spindle rotation accuracy of a high-efficiency precision CNC grinding machine is tested by using the spindle rotation accuracy tester produced by Lion Precision Company. The results show that the spindle rotation accuracy of the grinding wheel spindle system is very high. The results of the research on rotation accuracy, static rigidity, vibration resistance and thermal stability of the grinding wheel spindle show that it is a grinding wheel spindle with excellent performance. This will improve the grinding performance of CNC grinding machines.
