In the actual production, according to the product, size, batch of different, low, medium and high-grade machine reasonable configuration, scientific management, in order to effectively improve productivity, labor productivity. Industrial machine tools Possession of the amount ,
The ratio of medium and high is about 20:70:10, the ratio of production is about 5:65:30, while the developing countries are 80:17:3,70:25:5. Industrialized countries, high-grade ; Developing countries are low, mid-range, and thus productivity, labor productivity difference between the developing countries should strive
small and medium-sized flexible production of automated NC machine. At the technical level, the United States, Germany, daily first-class, in the third stage; Italy, Britain, France second-class, in two, three; China, Spain, At present, the world's machine tools have about 14 million units
Since the world's first machine tool in 1769, more than 230 years, the world machine tool development has gone through three stages: (1) sporadic small industrial production of ordinary machine tools; (2) a large number of large-scale production of automated automated machine tools;
