Our country’s heavy-duty CNC machine tools have made great breakthroughs, but the gap between domestic and foreign is still obvious
1. The rapid development of domestic heavy-duty CNC machine tools basically meets the domestic demand for medium and high-end products
In recent years, driven by the demand for aerospace, nuclear power plants, and heavy mining equipment, the market demand for heavy-duty CNC machine tools in China has grown rapidly. Domestic heavy-duty CNC machine tools have developed rapidly, such as heavy-duty CNC boring machines, heavy-duty CNC milling machines, and heavy-duty CNC machining centers. Output has steadily ranked at the forefront of the market, and market consumption has grown steadily.
Our country’s heavy-duty CNC machine tools have made great breakthroughs.
In terms of key technologies, our country has successively made breakthroughs in five-axis linkage technology, motion compensation technology, error control technology, and hydrostatic guideway technology. The machining accuracy and reliability of heavy-duty CNC machine tools have made great progress.
In terms of key parts and components, our country has successively realized the localized production of high-power dual-angle milling heads for heavy-duty machine tools, heavy-duty interchangeable worktables and other components; in terms of complete machine production, CNC double-gantry boring and milling machines, combined processing of gantry turning and milling Machine tools and pentahedral gantry machining centers have been successfully developed and played a key role in the production of C919, J-20 and key components of nuclear power plants.
On the whole, our country’s heavy and super heavy CNC machine tools have been able to meet the needs of our country’s heavy mining, nuclear power plants and aerospace industries for medium and high-end heavy CNC machine tools. Some products have broken the record of the largest processing size abroad, and the gap with foreign advanced enterprises is gradually Zoom out.
2. There is still a gap between heavy-duty CNC machine tools and foreign countries, and high-end products are highly dependent on foreign countries.
There is still a gap between our country’s heavy-duty CNC machine tools and foreign countries. The production of high-end heavy-duty CNC machine tools is basically controlled by Western countries such as Germany, Italy, and the United States. The highest level.
From the perspective of machine tool production technology, there is little difference in structure between our country’s heavy-duty CNC machine tools and foreign countries, and the new technologies adopted are almost the same. However, our country’s heavy-duty CNC machine tool parts manufacturing accuracy and overall machine accuracy retention and reliability still need to be improved, especially in the field of key CNC systems and functional components, foreign manufacturers still need to support them.
In addition, compared with leading foreign companies, our country’s heavy-duty CNC machine tool companies have weak independent innovation capabilities and lack research on basic common technologies, key core technologies, and forward-looking technologies; product supply and demand structure is unbalanced, and production capacity is mostly concentrated in the low-end product market. However, the high-end heavy-duty machine tools and services required by domestic key user areas, especially specialized products for high-end market segments, are still insufficient and have to rely on imports.
3. The structure of our country’s heavy-duty CNC machine tool industry is relatively concentrated, and Qi’er machine tool is at the leading domestic level
Heavy-duty CNC machine tools are the key equipment that serves national key industries such as national defense, aerospace, and shipbuilding. With high technology integration and large capital investment, state-owned enterprises have occupied a leading position in the field of our country’s heavy-duty CNC machine tools by virtue of years of technology accumulation.
Among them, Qier Machine Tool is the leading enterprise in our country’s heavy-duty machine tools, and its heavy-duty CNC machine tools rank first in the domestic industry in terms of production scale, market share and variety series.
After years of technical research, our country’s heavy-duty CNC machine tools, especially super-heavy CNC machine tools, have basically been able to meet the needs of large-scale domestic projects. Beiyi Machine Tool, Shenyang Machine Tool and Wuhan Heavy Machinery are at the domestic advanced level in the field of heavy-duty CNC machine tools.
However, compared with foreign countries, our country still has a big gap. In the future, it is still necessary to increase the research and development of CNC systems and key components to further improve the processing accuracy and reliability of heavy-duty CNC machine tools.
