With the development of electronic information technology, the world machine tool industry has entered a digital manufacturing technology as the core of the mechanical and electrical integration era, in which the NC machine tool is one of the representative products. CNC machine tool manufacturing process is an important basis for the master and the national economy. It provides equipment and equipment for all sectors of the national economy, and has unlimited economic and social effects.
At present, China's machine tool industry is weak, control system, a generator, a gear box, bearing design and production capacity with foreign advanced level compared to have a larger gap, fan bearings, control systems and other key components also need to imported from abroad. One of the key factors is that our manufacturing process and processing equipment is relatively backward.
The development of CNC machine tool industry in China
The demand of the domestic numerical control machine tool is increasing day by day, the development of the numerical control machine tool has promoted the innovation of the function component of the numerical control machine tool. At present, China's high-end CNC machine tool key functional components industry can not meet the domestic needs, the domestic CNC functional components industry mainly in the following problems.
1, adaptability and satisfaction is far less than the market demand
From the current development trend of China's CNC machine tool, the adaptability and satisfaction of domestic functional components is far less than the market demand.
2, the size of the production enterprise of our country numerical control function component is small
According to statistics, China's fixed assets reached 10 million yuan more than the functional components of the production enterprises have more than 70, accounting for 10% of the total production enterprises.
3, a large number of core components rely on imports
China's CNC machine tool industry development is remarkable, in 2008 China's CNC machine tool industry completed industrial output value of 34723 yuan, product sales output value of yuan, an increase of 27.5% and 26% respectively.
4, the lack of high technical content of the threat of industrial safety
China's machine tool exports year after year to maintain the growth of gratifying situation, but the "volume increase price reduction" of the embarrassment directly reflects our technical level. The lack of a large number of core technologies and the dependence of key parts directly affect the safety of the machine tool industry in our country.
However, machine tool leading enterprises have been aware of the important driving force of energy equipment, and began to actively research and development related machine tools. Heavily armed independent research and development of XKD2755 * 570-2M type NC set beam Ssangyong door mobile boring and milling machine for wind power gear this large size parts processing; Qi second machine has independently developed the world's largest heavy tk6932 CNC double column floor boring and milling machine provides a key cutting machine for large hydropower generating units, nuclear power plant equipment of large workpiece.
On the one hand, machine tool as the tool of equipment manufacturing, energy equipment manufacturing industry to upgrade the basic guarantee. On the other hand, energy equipment industry has a strong effect on the machine tool industry, can help the machine industry to achieve industrial structure optimization and upgrading." Relevant sources said.
Under the support of energy equipment and other important industries, the domestic machine tool industry in the industrial structure and product structure there have been some encouraging trends, such as production line manufacturing technology and application in the field has made new progress; as one of the main models of the large amount of industry equipment manufacturing, and processing center in function to composite development. In performance to the development of high speed and high precision; precision machine tool into micro and nano era; intelligent technology obtained widely used; industrial robot industry rapid development, become the important products and key technology of intelligent manufacturing and industrial automation.
