CNC carving and milling machine mechanical structure of the static, dynamic characteristic optimization

Optimize the CNC carving and milling machine tool dynamic characteristics is in order to improve the dynamic stiffness of CNC carving and milling machine tool, in order to improve the natural frequency of the CNC carving and milling machine tool for the optimization goal, hope that through structural optimization makes the natural frequency was improved, and greater than the machine cutting the maximum vibration frequency of 300 hz ( The equivalent of spindle speed of 9000 r/min) 。 At the same time hope that the spindle in common speed 6000 r/min ( The vibration frequency of 200 hz) When machine tool vibration deformation is reduced.
