In the search, a lotof related data access research of machine tool automation technology, in-depth research and analysis, and describes the design of machine tool control system. The whole process is mainly carries on the design to the main drive lathe. CNC lathe main drive design, including the design, three aspects: according to the design of machine tool use, the given specifications, spindle speed limit, speed ratio determined sequence or series, other relevant motion parameters, selected at speed of the main shaft; through analysis parison, select the transmission scheme; develop structure or structure, develop speed diagram; to determine the number of gear teeth and belt pulley diameter; drawing drive system diagram. Secondly, based on the machine type and motor power, determining the spindle and the transmission of putation speed, initial drive shaft diameter, the gear modulus, determine the transmission belt type and number of roots, friction plate size and number of
