With the development of electronic information technology, the world machine tool industry has entered the era of mechatronics with digital manufacturing technology as its core, among which CNC machine tools are one of the representative products. CNC machine tools are an important basis for the processing of the manufacturing machine and the national economy. It provides equipment for all sectors of the national economy and has unlimited economic and social effects.
“The demand for domestic CNC machines is increasing. The development of CNC machine tools has promoted the innovation and upgrading of the functional components of CNC machine tools.” Luo Baihui, chief researcher of Jinmo Machine Tool Network, said that at present, China's machine tool industry has weaker capabilities, control systems, generators, and gears. There is a big gap between the design and production capacity of the box and bearing compared with the advanced level in foreign countries. The key components such as the bearing and control system of the fan also need to be imported from abroad. One of the key factors of the restriction is that our manufacturing process and processing equipment are relatively backward.
At present, the key functional components industry of high-end numerically-controlled machine tools in China cannot meet the domestic needs. The domestic CNC functional component industry mainly has the following problems.
1. The adaptability and satisfaction are far from the market demand. From the current development trend of China's CNC machine tools, the adaptability and satisfaction of domestically-made functional components is far from the market demand.
2. The size of China's CNC functional components manufacturing enterprises According to statistics, there are more than 70 functional component manufacturing enterprises with fixed assets of over 10 million yuan in China, accounting for less than 10% of all production enterprises.
3, a large number of core components rely on imports China's CNC machine tool industry's development is remarkable, in 2008 China's CNC machine tool industry completed industrial output value of 347.33 billion yuan, product sales value of 334.83 billion yuan, an increase of 27.5% and 26.0% respectively.
4, lack of high-tech threat to industrial safety China's machine tool exports to maintain growth in the gratifying trend year after year, but the "decrease by volume" of the embarrassment directly reflects our technical level. The lack of a large number of core technologies and the dependence of key components directly affect China's machine tool industry safety.
However, machine tool leaders have realized the important driving force of energy equipment and have begun to actively develop related machine tools. The XKD2755×570-2M numerically-controlled fixed beam double-gantry mobile boring and milling machine independently developed by Wuzhong is suitable for the processing of large-sized parts of wind power gears; the world’s largest heavy-duty TK6932 CNC double-column landing-type milling and boring machine independently developed by Qi 2 Machine is a large-scale hydropower generating unit, The ultra-large workpiece machining of nuclear power plant equipment provides the key processing machine tools.
"On the one hand, machine tool tools as the parent equipment for equipment manufacturing is the fundamental guarantee for upgrading the energy equipment manufacturing industry. On the other hand, the energy equipment industry has a strong pulling effect on the machine tool industry, which can help the machine tool industry to optimize and upgrade the industrial structure. Luo Baihui said.
Under the support of important industries such as energy equipment, the industry structure and product structure of the domestic machine tool industry have seen some promising development trends: For example, new progresses have been made in the manufacturing technology and application fields of the production line; One of the models, the machining center develops to a complex one in terms of function, and develops in terms of performance to high speed and precision; the precision machine tool enters the micro-nano era; the intelligent technology is widely used; the industrial robot industry develops rapidly and becomes intelligent manufacturing and industrial automation. The key technologies and important products.
Recently, leading players in the industry, such as Zoomlion and Sany Heavy Industry, have acquired foreign companies. China's CNC machine tool industry in the “bottom valley” has shown internal adjustment and the pace of internationalization has begun to accelerate. According to data from the China Investment Association, in the first half of the year, the value of domestic CNC machine tool industry exports reached 3.825 billion yuan, an increase of 32.9% year-on-year.
After a period of rapid development, China's CNC machine tool industry has achieved a significant advancement in the level of science and technology, in particular, some machine tools with good market prospects, such as CNC cutting machines, CNC flame cutting machines, CNC plasma cutting machines, etc. Equipment in the intelligent technology to achieve international standards, cheap products have sufficient international competitiveness. Luo Baihui believes that with the government's "stable growth" signal factor, it is expected that the industry as a whole will still achieve a 12% increase, with an increase in exports of more than 30%.
