1950 period after World War II into the automation, due to the NC and group control machine tools and automatic lines, the development of the machine began to enter the era of automation. CNC machine tools are computer after the invention, the use of digital control theory, the processing procedures, requirements, and tool change operation code as digital and text information stored axle shaft drilling dedicated direct sales, according to instructions issued by the control of its machine, press established requirements for the new machine processing. The world's first CNC machine tools (milling) was born (1951) CNC machine program, the United States Parsons (full name of John Parsons) in the development of cross-sectional profile inspection of aircraft propeller blade plate leaf processing machines to the US Air Force special axle shaft proposed drilling, with the participation and assistance of MIT, and finally succeeded in 1949. In 1951, they officially made the first prototype tube CNC machine tools, automation successfully solved the problem of complex parts of many varieties of small batch processing. Later, on the one hand from the CNC milling machine to extend the principles of milling and boring machines, drilling machines and lathes, on the other hand, the transition from tubes to transistors, integrated circuits direction. In 1958, the United States developed into automatic tool change to multi-step process of machining centers. Vertical lathe spindle axis perpendicular to the horizontal axle dedicated drilling supplies, workpiece clamping in a horizontal rotary table, knife move on the beam or column. Suitable for processing large, heavy, difficult to install on the lathe workpiece, generally divided into two major categories of single and double column. Relieving lathes at the same time turning axle shaft drilling dedicated manufacturers, tool holder periodically for radial reciprocating cutter used forklifts, hob etc. forming the tooth surface. Usually with a shovel grinding attachment, by a separate motor-driven small shovel teeth grinding wheel surface. Specialized lathe lathe is used for processing certain types of specific surface of the workpiece, such as a lathe crankshaft, camshaft lathe, lathe wheels, axles lathes, roll lathes, lathes and ingots. Combined lathe is mainly used for turning, but add some special parts and accessories after, but also for boring, milling, drilling, insert, grinding and other processing, with "a machine can" feature, for engineering vehicles, ships or mobile repair work on the repair station.
