摘　　要：超高速离心磨床是一种新型的磨床,与传统超高速磨床相比,其CNB砂轮上装了一个电主轴。在确定其电主轴几何尺寸的基础上建立相应的三维模型,利用Ansys进行仿真分析,考察模型是否存在干涉、关键零部件的受力情况与刚度等,分析不同的转速对电主轴刚度和系统稳定性的影响。Ultra high speed centrifugal grinding machine is a new type of grinding machine, compared with the traditional ultrahigh speed grinding machine, its cubic boron nitride （CBN） grinding wheel is equipped with a motorized spindle. Three-dimensional （3D） model is established based on the geometry of motorized spindle. The si,nulation analysis was can＇ied on using ANSYS. Whether there was interference, situation of key components of stress and stiffness in the model were detected. Analysis is carried on the influence of different rotational speed of spindle on stiffness and the stability of the system.
