摘　　要：为提高空气静压主轴回转精度,基于空气静压主轴的回转运动特性,采用标准球单点双向法对主轴回转误差进行测量,分析了被测主轴的回转精度,测得不同供气压力下的被测气浮主轴止推盘的承载性能以及实验气浮主轴的回转精度;对实验中产生的误差进行分析。结果表明:被测实验主轴的轴向回转精度稳定在0.5μm左右,在50 r·min^-1转速下径向回转精度为25~28μm。In order to improve the rotational accuracy of aerostatic spindle,according to the characteristics of the rotary motion of the aerostatic main shaft,the rotation error of spindle is measured by standard sphere single point two-way method.The rotation accuracy of the tested spindle is analyzed.The bearing performance of the tested air-floating spindle thrust disc under different air supply pressures and the experiment are measured.The rotation accuracy of the air-floating spindle;the error generated in the experiment is analyzed.Experiments show that the axial rotation accuracy of the tested experimental spindle is stable at about 0.5 μm,and the radial rotation accuracy is 25~28 μm at 50 r·min^-1.
