In my design, I take some main technical parameters of medium CNC lathe for reference. Furthermore, I design the maximum and minimum speed for spindle in the main transmission ,the determination of the transmission range, the estimate of motor power, the select of motor, the chart of Speed and power for headstock, the estimate of the size for shaft the estimate for gear modulus, the checking for the shaft , the gear modulus, the determination of the transmission ratio in servo feed transmission, the select of servo motor , the select of ball screw pair, the design of the parameter for servo feed transmission as well as its caculation.
