The CNC machine tools are the basic device for the information integration and system automation. It replaces the complex transmission chain link structure in the machine tools by software controlling, to complete the processing of complex surfaces, which greatly enhances the precision of the products and equipments, making the shape more beautiful and personalized expression. The CNC machine tools have a good processing precision and consistency, which ensure the standardization and serialization of product components, as well as the good interchangeability. This paper focuses on the design of the transmission structure of the A-axis andthe Z-axis which are part of the XK2140-5-axis machining center, here are detailed data: First. Structure calculating of XK2140-5-axis machining center in Z-axis. Second. Structure calculating of XK2140-5-axis machining center in A-axis. Third.Drawing graph and virtual configuring of XK2140-5-axis machining center in Z-axis and A-axis. The design of the A-axis and Z-axis can not only help the processing center to complete some complex movements, but also have greatly affection on the precision of the machine tools. Also, this would solve some usual problems of transmissi
