1950 during World War II after entering 3000t press 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 storage, in accordance with its instructions issued by the control machine tools, according to the established requirements for processing The new machines. 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 proposed, 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. 1958 presses, the United States developed a tool to automatically replace, to perform multi-step process of machining centers. Many types of machine tools. For example: General Machine: lathe, planer, milling machines, presses, grinders, EDM, EDM 1000 presses, drilling, boring, hobbing, Riveting, bending machines. Special tools: specialize thread rolling machine, upsetting machine; specialized crankshaft crankshaft grinding mill. Each machine is divided into many forms and models. For example, the cutting line on the first floor cited: DK7720 WEDM, DK7763B, D EDM 2500t press, DK77 Series Standard EDM, DK77 Series CNC WEDM, DK Series CNC WEDM, GS EDM CNC system Chen Hua Machinery Co., Ltd. Qingdao is a vibrant emerging conglomerate (under a: Qingdao Licang southeast drainage foundry, Chen Hua model plant, rubber plant dies, welding sheet metal stamping plant, machining plant, equipment manufacturing plants, two bronze handicraft factory joint venture). Has a staff of 70, two senior economist, a senior accountant, senior engineer 5, 16 engineers, technicians and 18; has an experienced, high-level technical workers.
