Discussion on the Coordinated Development of Modern CNC Machine Tools and Cutters
October 16, 2023
Cutting tools and machine tools are two subsystems of the manufacturing technology system, which are both independent and complementary, and continue to promote the improvement of labor productivity in the manufacturing industry.
At present, along with the vigorous development of modern digital manufacturing technologies, modern high-efficiency cutting tools characterized by "high precision, high efficiency, high reliability, and specialization" (prompt: the industry also calls "three highs and one special") are quickly replaced. The traditional standard tool, as the final execution part of the digital manufacturing system, plays a key role in processing. Although its price is much higher than traditional standard tools. However, because of its excellent performance, the processing quality and efficiency are greatly improved, which enables the manufacturing industry to increase labor productivity and reduce costs, and to obtain greater benefits.
The annual manufacturing cost of global manufacturing industry reaches more than 400 billion US dollars, of which the tool cost is about 20 billion US dollars. In recent years, manufacturing industries in developed countries have adopted modern high-efficiency cutting tools to increase labor productivity. The annual cost savings for manufacturing industry amounted to US$100 billion, which is far higher than the investment in cutting tools. Therefore, all countries have taken the development of modern and efficient tools as an important means to increase the competitiveness of the manufacturing industry. The concept that "cutting tools are productive during processing is not a consumable item" has reached a consensus in developed countries. Cutting tool consumption accounts for 3% to 4% of manufacturing costs. In China's manufacturing industry, most companies still rely on cheap labor as the main means to reduce costs, and less attention is paid to improving efficiency through improved processing methods. As a result, the level of tool consumption in China's manufacturing industry is generally low, accounting for only 1 of manufacturing costs. % to 2%.
Another fact that deserves attention is: In Germany, the United States, Japan, and other manufacturing powerhouses, the laws of modern CNC machine tools and high-efficiency tool coordination and balanced development are very obvious. The purpose is to provide the manufacturing industry with an optimal configuration that can fully realize the potential of the equipment. And solutions. In the developed countries, in the normal years of stable economic development, the annual scale of tool consumption is generally about 1/2 that of machine tool consumption. For example, when the annual consumption of machine tools is 6 billion U.S. dollars, the consumption of tools is generally about 3 billion U.S. dollars. Only in the years of economic recession will this ratio change as the scale of investment shrinks. However, the regularity of coordinated development of machine tools in developed countries does not appear in China. Especially in the last 10 years, the consumption of machine tools in China's manufacturing industry has taken the lead and the tool consumption has been left behind. This strange phenomenon has become a feature of the development of China's machine tool industry. Such as: In 2010, China's machine tool consumption reached a record level of 28.5 billion US dollars. In the same year, tool consumption was 5 billion U.S. dollars, and tool consumption was only 18% of machine tool consumption. It is much lower than the level of 50% in developed countries.
