China's CNC machine tools continue to "break out"

The 10-meter CNC bridge-type gantry five-axis linkage turning and milling combined machining machine developed by Beijing No. 1 Machine Tool Plant can complete the processing of key parts of nuclear islands of large nuclear power plants.

——The world's largest 36,000 tons of ferrous metal vertical extrusion machine developed by Inner Mongolia North Heavy Industry Group solved key technologies such as mold design, transmission and control operating system design and manufacturing, and broke the long-term dependence of China's large-diameter thick-walled tubes. Subject to the situation of people, Japan's similar products have drastically lowered the price.

——The ultra-heavy-duty CNC floor-standing milling and boring machine developed by Qiqihar Second Machine Tool Group can meet the manufacturing needs of super-large parts in power generation, shipbuilding and petrochemical industries.

The equipment manufacturing industry is known as the "industrial parent machine" and is the cornerstone of the manufacturing industry. The various types of facilities required for industrial modernization are inseparable from high-end CNC machine tools and basic manufacturing equipment.

During the "Eleventh Five-Year Plan" period, with the breakthrough of a series of key technologies and the formation of independent production capacity, China began to highlight the "heavy encirclement" of "foreign manufacturing" and entered the ranks of the world's high-speed CNC machine tools and high-precision CNC machine tools.

“In the past five years, the key tasks of 'high-end CNC machine tools and basic manufacturing equipment major projects' have been completed one after another. China's machine tool industry has developed rapidly, and its output value and output rank first in the world. The numerical control rate of domestic machine tools is 35.5% from the end of the 'fifteenth' Raised to 51.9% at the end of the '11th Five-Year Plan'," said Xu Wei, director of the Major Specialized Office of the Ministry of Science and Technology.

Although China has already become a major power producer, the contradiction of big but not strong has always plagued the scientific development of the industry. Integrated circuit chip manufacturing equipment, large-scale petrochemical equipment, key equipment for automobile manufacturing, and advanced intensive agricultural equipment have long relied on imports.

In order to reverse the "big but not strong" situation as soon as possible and better adapt to the needs of the transformation of economic development mode, "high-end CNC machine tools and basic manufacturing equipment" was included in the "National Medium- and Long-Term Science and Technology Development Plan (2006-2020) One of the 16 major projects identified, shouldering the mission of focusing on the development of high-end CNC machine tools needed for aerospace, marine, automobile manufacturing, power generation equipment, etc., to meet the needs of major domestic industries.

According to reports, during the "Eleventh Five-Year Plan" period, "high-end CNC machine tools and basic manufacturing equipment major projects" jointly established 268 projects, arranged for more than 9 billion yuan, and participated in more than 10,000 research and development personnel. Among them, 82% of the projects led by enterprises and 88% of central government investment.

“In the process of major special implementation, the company has truly become the main body of innovation and R&D. As an industry leader, 'Beiyi' is committed to providing key infrastructure equipment for the development of key industries in the national economy, and our technical transformation investment is concentrated on national demand.” Beijing Liu Yuling, chief engineer of the First Machine Tool Plant, told Xinhua News Agency.

Wu Bolin, executive vice president of China Machine Tool Industry Association, believes that in recent years, China's machine tool industry has further strengthened independent innovation and made positive progress in industrial restructuring and product upgrading.

The CNC system is equivalent to the "brain" of CNC machine tools. During the "Eleventh Five-Year Plan" period, I have developed multi-axis multi-channel, bus-type high-end numerical control device products in the numerical control system. Wuhan Huazhong Numerical Control Co., Ltd. and Shenyang Gaojing Numerical Control Technology Co., Ltd. have completed the production of 50 sets of open all-digital high-end numerical control devices.

“In recent years, Huazhong CNC has started to develop independent and innovative CNC technology. The technological progress achieved in 2010 alone is equivalent to the sum of the past 10 years.” Wuhan Jizhong Numerical Control Co., Ltd. Chen Jihong said.

Academician Lu Bingheng, the head of the “High-end CNC Machine Tool and Basic Manufacturing Equipment Major Project”, said that at the end of the “Twelfth Five-Year Plan”, China will realize the matching and coordinated development of CNC systems, functional components, tools and other mainframes, and master a batch of hosts. The core technology of CNC systems and key functional components.

According to the special plan, by 2020, about 80% of the high-end CNC machine tools and basic manufacturing equipment required for the manufacture of aerospace, marine, automotive and power generation equipment in China will be based in China. The overall technical level of high-end CNC machine tools and basic manufacturing equipment has entered the international advanced ranks, and some products are internationally leading.

To speed up the transformation of the economic development mode, the fundamental way out lies in independent innovation. More and more breakthroughs in key technologies make localization of high-end CNC machine tools no longer a dream.
