The hottest medium and high-end CNC machine tool i

  • Detail

As a machine for manufacturing machines, China's machine tool industry has become the largest importer and consumer for eight consecutive years after more than a decade of development. Although China is currently a large machine tool manufacturing country, there is a trend that the manufacturing process tends to be low-end. Duanjiaxuan, a researcher in the machinery industry of CIC, said in an interview

according to the data released by China Machine Tool Industry Association, in 2011, the import growth rate of China's machine tool products remained high, with a cumulative import of 20.29 billion US dollars and an export of only 8.9 billion US dollars

201 stepper motors are open-loop control elements that convert electric pulse signals into angular displacement or linear displacement. In 0 years, China's machine tool trade deficit was only $8.042 billion, while in 2011, China's machine tool industry trade deficit was as high as $11.39 billion, and the number of imports increased year by year has increased or not decreased. The increase in the number of imports means that China's machine tool industry is now like a fat man

the main reason for this gap is that, on the one hand, in recent years, the explosive growth in the demand and supply of ordinary machine tools in China has restricted the improvement of the overall process level of users, and also slowed down the consolidation of the machine tool industry. "Lu Guoyang, Secretary General of China Polyurethane Industry Association, said that the improvement rate of system level. On the other hand, domestic enterprises lack the ability of independent innovation and can not meet the market demand of products with high technical requirements such as heavy machine tools, which is also the structural problem of China's machine tool products. Li Junhua said

Qian Zhiqiang, vice president of Kunshan aokesen Machinery Co., Ltd., said in an interview that the core technology of machine tools is CNC system. At present, not to mention the system, even the domestic CNC machine tools with slightly better quality, the high-precision manufacturers and equipment performance used are very critical ball screws, and the bearings are mainly imported from Japan. However, the ball screws and bearings produced in China have problems in accuracy and service life. All major domestic machine tool plants purchase 100% of their CNC systems

it is understood that in the machine tool industry, numerical control machine tools are based on the number of axes, 3-axis and 5-axis are medium and high-end products, and more than 5-axis are high-end products. At present, China's machine tools are mostly low-grade products with less than 3 axes in the iron ore futures market

as for why there are many low-end products in China, Duan Jiaxuan said that China's machine tool manufacturing started late, and the lack of professionals and other shortcomings cannot be made up in a short time. To reduce dependence on imports, we should vigorously introduce and cultivate talents, and the solution is to increase investment in machine tool research and development. Whether domestic machine tools can break through the siege of imported machine tools depends on whether China's high-end machine tool manufacturing can reach the world leading level in the future

technological innovation and machine tool product organization upgrading are the development direction of domestic machine tool manufacturing industry. In the current economic situation, enterprises with low efficiency and high energy consumption are bound to be eliminated. Only by complying with the market demand and taking the road of high-tech sustainable development can they have a foothold in the market. Industry experts said that a large part of China's imported machine tools are middle-end machine tool products, and the demand for middle-end machine tool products has increased significantly, reflecting the defects in the technical level and industrialization of domestic medium and high-end products
