前言随着科学技术的高度发展,对高精度仪器和机床主轴系统的精发,提出越来越高的要求。主轴是轴系系统中最关键的零件,其精度高低直接影响到轴系精度。因此如何提高主轴本身精度,已普遍引起人们的关注。为了进一步探索高精度主轴磨削加工工艺,分析影响高精度主轴精度的因素,找出主轴精度较难达到圆度误差不大于0.15微米的根 Preface With the high development of science and technology, high-precision instruments and machine tool spindle system of fine, put forward higher and higher requirements. Spindle shaft system is the most critical parts, the level of accuracy directly affects the shaft accuracy. Therefore, how to improve the accuracy of the spindle itself has caused widespread concern. In order to further explore the high-precision spindle grinding process, analyze the factors that affect the accuracy of high-precision spindle to find the spindle precision is difficult to achieve circularity error of not more than 0.15 microns root
