主轴部件是数控机床的重要组成部分,而主轴又是主轴部件的核心零件,主轴整体质量的优劣,将最终影响数控机床的运行稳定性和加工精度.以车床主轴的开发设计为例,论述了主轴主要参数指标和技术要求等方面的确定过程,完成了主轴的改进和定型,效果显著.%Spindle components are very important parts of the CNC machine tools, the spindle is the key part of spindle components, it's quality good or bad could influence the running stability and processing precision of machine tools. Take the case of the lathe spindle developing and designing, discussing how to design the main parameters and technical requirements of the spindle, and fulfilling the improving and setting, the effect is perfect.
