Purchasing new numerically controlled machines is an important way to improve production precision and efficiency, but it may not come true to many enterprises because it cost much. Adopt the economic number controls system to carry on a number to control to turn a reformation to the common tool machine, particularly in keeping with our country the common tool machine own to have great capacity, the small concrete state of the nation of the production scale. This design is to control to turn a reformation to the number of C6150 common lather，mainly on the creative design of original structure of lathe to make lathe relative perfect. While in the process, we do detailed calculation and design of servo system, NC and so on. Design when I first CNC machine tool system, the overall design, and then calculated the feeding system, the gearbox ratio and the stepper motor, compu
