The hottest equipment giant ship breaks the waves

Equip the "giant ship" to break the waves

if you want to do good things, you must sharpen your tools first. Strong equipment means strong national strength. In today's world, all countries with strong national strength are powerful in equipment manufacturing. The United States, Japan and Germany have long regarded equipment manufacturing as the backing of their strong national strength. High end equipment has become the core and indispensable weapon of the game between big countries

China has successfully independently developed various new materials and equipment for power transmission and transformation represented by a full set of UHV AC and DC power transmission and transformation equipment, comprehensively mastered the complete set of UHV power transmission technology, realized the transformation from made in China to created in China in this field, and occupied the commanding height of International high-voltage power transmission technology. On January 11, 2016, the construction of the 1100 kV HVDC transmission project in the south of Zhundong Anhui (Changji, Xinjiang, Xuancheng, Anhui) began. This is the UHV 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 the pressure calibration of the million ton ethylene complete set of equipment has made China the fourth country in the world to have the design and manufacturing capacity of the three million ton ethylene machines (cracking gas compressor, propylene compressor and ethylene compressor) after Japan, the United States and Germany, completely ending the long-term dependence on imports and making a significant contribution to the development history of China's advanced equipment manufacturing industry

as the mother machine of manufacturing machines, machine tools have the closest relationship with the manufacturing industry and are 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 industrial technical level has been significantly improved, the gap with the international advanced level has been significantly narrowed, and some products have reached the international advanced level. They have successively provided key manufacturing equipment for major national projects such as nuclear power and large aircraft, as well as a number of national key projects such as new fighters and launch vehicles, and have effectively supported and guaranteed national security. For example, the technical parameters and technical level of the 25 meter column mobile vertical milling lathe are at the world leading level; The successful development of heavy equipment such as 80000 ton large die forging press and 10000 ton aluminum plate tension tensile machine has filled the technical gap in the integral molding of large key parts in the domestic aviation field; The successful development of 1500 mm aspheric ultra precision turning and grinding compound processing machine tool has filled the gap of domestic high-precision large aperture optical aspheric element processing equipment, and broken the technical blockade and equipment embargo imposed by foreign developed countries on China; In the field of automobile manufacturing equipment, the industrialization of numerical control forging and forming equipment has achieved the most remarkable results. Among them, the stamping equipment for large automobile panels has reached the world advanced level, has the ability to compete in the international market, and has successfully exported 9 production lines of Ford Motor Factory in the United States

the development and progress of equipment manufacturing is not only the improvement of equipment manufacturing capacity, but also accompanied by the transformation of thinking and mode. The emergence of 3D printing technology has overturned the previous mode of manufacturing objects through cutting or mold, and provided a new way for the development of equipment manufacturing. The technology has been effectively applied in aerospace, biological and medical industries. For example, the window frame of the main windshield on the nose of C919 large passenger aircraft, which is independently developed and has successfully flown, is 3D printed

the deep integration of information technology and manufacturing technology is the core theme of made in China 2025. Digitalization, networking and intelligence are important trends in the development of manufacturing industry and equipment manufacturing industry. The most prominent embodiment of the integration of industrialization and industrialization is intelligent manufacturing. The main carrier in the development of made in China 2025 in the next stage is also intelligent manufacturing. Intelligent manufacturing innovatively integrates emerging manufacturing, intelligence, information and other science and technology, making industrial interconnection, advanced sensing, big data, cloud computing, artificial intelligence and other technologies effectively applied in equipment manufacturing. It is not only the application of a single advanced technology and equipment, but also the transformation of a new model, which will accelerate the transformation and upgrading of China's equipment manufacturing industry

China has gone through more than 200 years of industrial history in developed countries in decades. In the process of development, we have built a huge production system and industrial system, and formed an equipment manufacturing system with our own characteristics. We are getting closer and closer to our dream of becoming a manufacturing power and will eventually surpass it. The giant ship of China's equipment manufacturing industry has been tested
