Green Manufacturing in the global advocacy of the environment, transformation of CNC machine tools to become a hot spot. It includes general of the CNC machine tools to transform and upgrade the CNC machine tools ????? This design is XA5032 ordinary vertical milling machine NC transformation. In order to achieve the XA5032 vertical milling machine into the general economy CNC milling machine, I am against this milling the main drive system, X, Y, Z to the feed system NC transformation, and to increase the CNC servo devices and systems. The main drive system, I choose FANUC AC motor drive through the belt drive spindle. The feed system, I replaced the original sliding screw ball screws, to improve accuracy and efficiency, and the original manual control, into the motor control. Converter to achieve through the main transmission and feed the CVT. SCM through the design of a control system.
