Domestic efficient tools and CNC machine tools work hand in hand
February 22, 2023
Since the reform, most of the high-efficiency advanced tools used in China's machining have been imported from abroad, including foreign-owned enterprises producing knives in China. We also export a lot of knives now, but mainly cheap and low-grade standard knives. In 2004, China produced about 2.5 billion pieces of tools, of which 2 billion pieces were exported by cheap low-end tools. In the next few years, the export is still medium and low-grade tools. Cutting tools and machine tools are two subsystems of the manufacturing technology system. They are independent development and complement each other, and continue to promote the improvement of labor productivity in the manufacturing industry. In the late 1970s and early 1980s, along with the rapid development of modern digital manufacturing technology, modern high-efficiency cutting tools featuring "high precision, high efficiency, high reliability and specialization" quickly replaced traditional standard cutting tools. As the final execution component of the digital manufacturing system, it plays a key role in the processing. Although its price is much higher than the traditional standard tool. However, due to its excellent performance, the processing quality and efficiency are greatly improved, so that the manufacturing industry can increase labor productivity and reduce costs, and obtain greater profits. According to statistics published by multinational groups, the annual cost of cutting and processing in the global manufacturing industry has reached more than 400 billion US dollars, of which the cost of cutting tools is about 20 billion US dollars. In recent years, the manufacturing industry in developed countries has adopted a large number of modern and efficient cutting tools to increase labor productivity. The annual cost savings for the manufacturing industry is 100 billion US dollars, far higher than the investment in tools. Therefore, all countries have developed modern and efficient tools as an important means to improve the competitiveness of manufacturing. The concept of “cutting tools are productivity, not consumables in the process of processing” has reached a consensus in developed countries, and the proportion of cutting tool consumption in manufacturing costs has reached 3% to 4%. In China's manufacturing industry, most companies still rely on cheap labor as the main means of reducing costs, and less focus on improving efficiency by improving processing methods to save costs. Therefore, the level of tool consumption in China's manufacturing industry is generally low, accounting for only 1 of the manufacturing cost. %~2%. Another fact worthy of attention is that in Germany, the United States, Japan and other manufacturing powers, the rules of modern CNC machine tools and efficient tools are coordinated and balanced. The purpose is to provide the best configuration for the manufacturing industry to fully utilize the equipment potential. And solutions. In developed countries, in the normal years of stable economic development, the annual scale of tool consumption is generally stable at around 1/2 of machine tool consumption. For example, when the annual consumption of machine tools is $6 billion, tool consumption is generally around $3 billion. Only in the years of economic recession will this ratio change as the size of the investment shrinks. However, the regularity of the coordinated development of such machine tools in developed countries has not appeared in China. Especially in the last 10 years, the consumption of machine tools in China's manufacturing industry has taken the lead, leaving tool consumption far behind. This strange phenomenon has become a feature of the development of China's machine tool industry. For example, 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, and tool consumption was only 18% of machine tool consumption. It is much lower than the level of about 50% in developed countries. At present, China's tool factories mainly produce traditional standard tools. Luo Baihui said that from the perspective of technological development trend of machinery manufacturing industry, the proportion of high-efficiency CNC machine tools in China's factories will increase year by year, and the demand for high-efficiency advanced tools will increase rapidly, while the demand for traditional standard tools will decrease year by year. .
