In recent years, domestic CNC machine tools have broken through the new achievements of foreign technology blockades, and have written a brilliant movement that has erected the backbone of the national numerical control system.
Encountered technical blockade during the technical climb
"If you want to become a big manufacturing country and a manufacturing powerhouse, Chinese equipment can't be without the 'Chinese brain.'" Chen Jihong, chairman of Wuhan Huazhong CNC, said, "As one of the most important industries in a country, China's CNC industry is facing both domestic technology and primary technology. The difficulty of climbing to the middle and high level is facing the grim reality of foreign technology blockade."
For the high-performance CNC system products with five-axis linkage above China's technology, some developed countries still impose restrictions on China's blockade. Exporting such products requires investigation and tracking of end users and end uses. Guilin Machine Tool Co., Ltd. twice refused to apply for a five-axis CNC system import license to foreign governments through the relevant state departments. The Southern Airlines Group spent $1 million to import a multi-axis CNC grinding machine. Foreign companies require equipment networking. In order to monitor and limit the field of equipment use.
In addition, foreign companies have also used technology transfer and joint ventures as a bait to maintain their advantages in the Chinese market in a step-by-step manner. A Japanese company once transferred the two system technologies that were behind it to the Beijing Machine Tool Research Institute, and also controlled the core hardware chips. We have not had time to digest and absorb it. The Japanese company has better performance and integration. The higher numerical control system products are pushed to the Chinese market, which has led to the idea that our introduction of technology to achieve industrialization has become a bubble.
Wang Zhirong, deputy general manager of Qiji Machine Tool Group Co., Ltd. told reporters that some Sino-foreign joint ventures are only a complete set of imported parts, and domestic assembly, we can not master its key technologies. In the process of introducing technology, many CNC personnel who are familiar with the technology and familiar with the Chinese market, many of which have been dug away by foreign parties, have finally made our company a “coreless†enterprise.
"The painful lesson has made the Chinese national numerical control industry understand the truth: for the strategic high technology such as the numerical control system, it can't be done by spending money; blindly emulating foreign countries, it will only be beaten and beaten by people. The only way out for China's CNC industry. It is independent innovation and revitalizes China's CNC industry with its own core technology." Chen Jihong said.
Based on independent innovation and seek new breakthroughs
The essence of the CNC system is the computer that controls the manufacturing equipment in real time, that is, the "brain" that commands the operation of the equipment. Foreign CNC systems usually use a dedicated computer as the technical route of the software and hardware platform. The Huazhong University of Science and Technology, which initiated the establishment of Huazhong CNC, abandoned the R&D ideas of “special computer-based†commonly used in the West, and walked out of the technical route of “using a general industrial microcomputer as a hardware platform and Dos and Windows as an open software platformâ€. This innovative technical route avoids the "reliability" bottleneck of hardware manufacturing that restricts the development of China's CNC system, making the Chinese CNC system industry and the international counterparts stand on the same starting line. The 4-channel and 9-axis linkage "Huazhong I" high-performance CNC system independently developed by Huazhong CNC has broken the foreign blockade and won wide acclaim from domestic and foreign customers.
In order to get rid of the situation of being controlled by key technologies, Dalian Machine Tool Group Co., Ltd. took the international technology strategy step earlier. By establishing a joint venture with the world's top companies, we will highlight independent innovation and integrate global technology resources. Nowadays, independent innovative products such as CNC system, vertical and horizontal machining center, turning compound center and gantry milling machine for key functional components are comparable in performance to world-class companies. Up to now, it has won the first place in the sales revenue of China's machine tool industry for seven consecutive years.
At present, China's CNC system industry is ushering in a new round of development opportunities. It is estimated that the domestic CNC machine tool consumption will reach 6 billion to 7 billion US dollars in 2010. In addition, the demand for high-end CNC machine tools and CNC systems in the aerospace, shipbuilding, major equipment manufacturing, automotive and parts manufacturing, and microelectronics equipment manufacturing industries will also increase dramatically. "The situation that key equipment and its control system rely on imports must be gradually changed. Otherwise, it will inevitably affect the sustained and healthy development of the national economy and national defense construction," said Wang Liming, deputy director general of China Machine Tool Industry Association.
"Efforts to reverse the situation of high-end CNC systems relying on imports" have become the consensus of the industry.
How to achieve this goal? Wu Bolin, the director general of the China Machine Tool Industry Association, believes that the key is to make the popular CNC system products industrialized as soon as possible and occupy the market in a short period of time. At present, more than 80% of the sales of CNC systems in foreign countries are popular CNC systems. If we can make breakthroughs in the rapid industrialization of popular CNC system products, China's CNC system industry is expected to fundamentally achieve strategic counterattacks. At the same time, it is necessary to establish a relatively complete independent innovation system for high-end CNC systems, improve China's independent design, development and complete sets of production capacity, create domestic independent brand products, and improve the overall technical level of China's high-end CNC systems.
Domestic CNC machine tools seek to break through foreign technology blockade
If the "industrial machine" CNC machine tool of the equipment manufacturing industry is likened to one person, then the function of the numerical control system is equivalent to the human "brain": through the command and dispatch of the numerical control system, a series of complicated processes can be used in one Automatically completed on the machine.
