Equipment manufacturing equipment "big ship" to break the waves

"If workers want to do good things, they must first sharpen their tools." Strong equipment is strong in national power. In today's world, countries with strong national power are all strong countries in equipment manufacturing. The developed countries such as the United States, Japan, and Germany have long used equipment manufacturing as the backing of their strong national power. High-end equipment has risen as the core and indispensable weapon for the game between big countries.

As a core component of manufacturing, equipment manufacturing is the foundation for the development of the national economy, especially industrial development. The establishment of a strong advanced equipment manufacturing industry is not only the support and guarantee for implementing the grand blueprint of “Made in China 2025”, but also the fundamental guarantee for improving China’s overall national strength and promoting the building of a manufacturing powerhouse. Since the 18th National Congress of the People's Republic of China, China has guided the development of innovation as a driving force, implemented the strategy of building a strong country, and focused on promoting high-end equipment manufacturing to go abroad and go global. After continuous catch-up and development, major advances have been made in equipment manufacturing in the key areas of China's economy, and a number of equipment products with core technologies have been formed. The technical level of some products has approached or reached the international advanced level. Major breakthroughs have been made in the fields of manned space flight, lunar exploration, deep diving, new regional aircraft, and high-speed rail transportation, and millions of tons of ethylene equipment, UHV power transmission and transformation equipment, and petascale supercomputers have leapt. Ranked in the forefront of the world.

China successfully developed a variety of new materials and new equipment for power transmission and transformation represented by a full set of UHV AC and DC power transmission and transformation equipment, and fully grasped the complete set of UHV transmission technologies, realizing the “Made in China” and “Created in China” in this field. "Transformation has occupied the commanding heights of international high-voltage transmission technology. On January 11, 2016, the ±1100 kV UHV DC transmission project started in Zhundong-Wannan (Changji, Xinjiang, Xuancheng, Anhui). This is the UHV power transmission project with the highest voltage level, the largest transmission capacity, the longest transmission distance and the most advanced technology level in the world. The successful development of one million tons of ethylene equipment has made China the world’s fourth-billion-ton-class ethylene “three-machine” (crack gas compressor, propylene compressor, and ethylene compressor) after Japan, the United States, and Germany. The countries with manufacturing capabilities have completely ended the history of long-term dependence on imports and have written a strong pen on the history of China's advanced equipment manufacturing industry.

As the parent machine of the manufacturing machine, the relationship between the machine tool and the manufacturing industry is the closest, and it is the basis for the development of other equipment. In recent years, China’s high-end CNC machine tools have achieved breakthroughs in a number of key technologies and equipment. The industry’s technological level has improved significantly, and the gap with the international advanced level has narrowed significantly. Some products have reached the international advanced level and have successively become major national nuclear power, large aircraft and other countries. A number of national key projects such as special and new fighters and launch vehicles provided key manufacturing equipment, which effectively supported and safeguarded national security. For example, the technical parameters and technical grades of the 25m vertical column turning vertical milling lathe are in the world's leading level; the successful development of heavy equipment such as 80,000 tons of large-scale die forging presses and 10,000-ton aluminum plate tension drawing machines fills domestic aviation. The technical blank of the overall molding of key large-scale important components in the field; the successful development of the 1500 mm aspheric ultra-precision grinding and lapping machine tool fills the gap in domestic high-precision large-aperture optical aspherical component processing equipment, breaking the practice of foreign developed countries in China. The technical blockade and equipment embargo; in the field of automobile manufacturing equipment, the industrialization of CNC forging and forming equipment has achieved the most significant results, among which the automotive large-scale panel stamping equipment has reached the world's advanced level, has the ability to compete in the international market, and has successfully exported Ford Motors USA. Factory 9 production lines.

The development and progress of equipment manufacturing is not only the improvement of equipment manufacturing capabilities, but also the transformation of thinking and mode. The advent of 3D printing technology has subverted the previous model of manufacturing articles through cutting or moulding, and provided a new way for the development of equipment manufacturing. This technology has been effectively applied in the fields of aerospace, biology and medical industries. For instance, the window frame of the main windshield of the C919 passenger aircraft head, which was independently developed by China and has been successfully tested, is printed in 3D.

The deep integration of information technology and manufacturing technology is the core line of “Made in China 2025”. Digitalization, networking, and intelligence are the important trends in the development of manufacturing equipment manufacturing industry. The most prominent manifestation of "integration of the two systems" is smart manufacturing. The main carrier in the development of the "Made in China 2025" stage in the next phase is also smart manufacturing. Smart manufacturing innovatively incorporates emerging scientific technologies such as manufacturing, intelligence, and information, enabling industrial Internet, advanced sensing, big data, cloud computing, artificial intelligence and other technologies to be effectively applied in equipment manufacturing. It is not only the application of a single advanced technology and equipment, but also the transformation of the new model, which will accelerate the transformation and upgrading of China's equipment manufacturing industry.

China has spent more than two decades of industrial history in developed countries in decades. In the course of development, we have built a huge production system and industrial system, and formed an equipment manufacturing system with its own characteristics. We are getting closer and closer to our dream of creating a strong country and will eventually surpass it. The "macrowarship" of China's equipment manufacturing industry has already been tested.
