摘　　要：孔轴线偏移是深孔加工中无法避免的问题,本文根据枪钻在深孔钻床上的加工特性,建立了枪钻的力学模型,利用有限元分析软件ANSYS Workbench对枪钻进行了静力学分析,研究了枪钻不同状态的孔轴线偏移量,同时探讨了孔轴线偏移量的影响因素。The deviation of hole axis is an unavoidable problem in deep hole machining. In this paper,according to the machining characteristics of gun drilling in deep hole drilling machine,the mechanical model of gun drilling is set up. The static analysis of gun drilling is carried out by using finite element analysis software Ansys Workbench,and the displacement of the hole axis in different states is analyzed,the influence factors of the deviation of the hole axis are also discussed.
