The XK2310 NC milling machine worktable system is one of the key components of the machine tool,its static and dynamic characteristics have a great influence on the machining accuracy of parts,in order to improve the static and dynamic characteristics of XK2310 worktable system,using ANSYS Workbench 14. 0 to analyzing the static and dynamic characteristics of worktable system,testing worktable system whether meets statics characteristics is the purposes of static analysis,the static analysis results show,in the cutting load,the maximum stress and strain values are far belowthe limit value of material,the maximum deformation within the scope of the precision; the purpose of dynamic characteristic is to knowwhether spindle producing excitation frequency causes worktable system resonance,modal analysis results showthat when spindle speed for 1539 r / min,2052 r / min,3077 r / min,4214 r / min,the excitation frequency of spindle and 1th,2nd order natural frequency of worktable system are equal,worktable system will be caused resonance.
