Design in motion, according to a given machine parameters, uses, analysis of a typical cutting process, the development of transmission to determine the structural form, map drawing speed, and speed calculation error, painting transmission map, calculate the diameter of pulley and gear teeth . Design power, according to motor power, transmission case to determine the calculation of the speed estimated by the shaft, the gear module to determine the size of gear。 the pletion of the assembly after the draft, check the stiffness of the main transmission case and the life. One of the main axis of the spindle box design in detail. In the structural design of the main line of the shaft, speed change mechanism, the spindle ponents, manipulation of institutions, and for the brake, tank, such as lubrication and sealing of the layout and structure design, and then all the major mapping out parts .
