影响机床整体刚度的重要因素是主轴和定位系统,而影响主轴组件弯曲刚度的因素是主轴的尺寸及形状,滚动轴承的数量及配置、前后支承的距离、主轴前端悬伸量等等。其中起决定性作用的则是主轴组件的整体设计及其滚动轴承的配置方式。一、对主轴组件刚度的影响由于影响主轴组件刚度的因素很多,所以在 The main factors affecting the overall stiffness of the machine tool are the spindle and the positioning system. The factors affecting the bending stiffness of the spindle assembly are the size and shape of the spindle, the number and configuration of the rolling bearings, the distance between the front and the back support, the overhang capacity of the spindle and so on. One of the decisive roles is the overall design of the spindle assembly and the configuration of its rolling bearing. First, the stiffness of the spindle assembly The impact of the spindle assembly stiffness due to many factors, so in
