文中介绍了精密车床主轴回转误差的一种补偿系统及补偿刀架结构,可以提高被加工件的圆度。实验表明,主轴转速为485 r/min 下,工件圆度误差由原来的1～1.7μm 减少到0.4～0.8μm,即补偿掉了40%～67%.文中还介绍了一种主轴回转误差的综合误关差计算机辅助测试系统,可绘制出径向、摆角、轴向3种回转误差的误差曲线图和误差频谱图,并打印出误差值、相关系数等。
In this paper, a compensation system of the turning error of the precision lathe spindle and the structure of the compensation tool holder are introduced, which can improve the roundness of the workpiece. Experiments show that when the spindle speed is 485 r / min, the roundness error of the workpiece is reduced from 1 ~ 1.7μm to 0.4 ~ 0.8μm, that is 40% ~ 67% of the compensation.The paper also introduces a spindle rotation error Comprehensive error clearance computer aided test system can be drawn radial, swing angle, axial error of the three kinds of gyroscope error curve and error spectrum, and print out the error value, the correlation coefficient.
