New developments in the heavy machinery industry (2)
<br> <br> advantages compared with foreign products, domestic products and foreign products the difference in the structure is not large, the new technology uses almost the same, the biggest difference is the speed of the core transmission parts, precision and reliability, As well as the manufacturing process level and quality of the entire Machine tool, this is the biggest advantage of foreign products. Although domestic manufacturers are slightly inferior to foreign advanced technology, they also have some advantages in favor of competition, and have great advantages in manufacturing capacity and price.
Super heavy-duty machine tools have reached the international advanced level. Nearly 10 sets of 16-meter CNC single-column vertical cars have been produced in China, but foreign production is rare. Now, Wuzhong is producing a 20m CNC single-column vertical milling lathe for the Shanghai Port Machinery Plant. The workbench bears 550 tons. It produces a 18m CNC single-column vertical car for a private enterprise in Fuchunjiang, Zhejiang. 10 meters, bearing 600 tons; also produced one of the world's largest ultra-heavy-duty CNC sleeper for Dongfang Motor Factory, processing 5 meters in diameter, 20 meters in length and bearing 500 tons. The German Schiess-Brighton company and the Shanghai Electric Group (Langang Nuclear Power Processing Base) signed a 22-meter CNC vertical milling lathe with a working table diameter of 12.5 meters, a main power of 240kW, a load capacity of 600 tons, and a C-axis milling head. 90% of the parts are made in China.

Premier Wen Jiabao said: "The machine tool is the working machine of the equipment manufacturing industry, and the modernization of the equipment manufacturing industry depends on the development level of China's machine tools." The domestic machine tool industry has a big opportunity.
Since the 1990s, foreign famous heavy-duty manufacturers have switched to the door, and the world's heavy-duty machine tool competitors have relatively weakened.
China is moving towards heavy chemical industry and becoming the world's largest machine tool consumer market, accelerating the development of the machine tool industry.
China is gradually integrating into the integration of the world economy, and famous foreign merchants have come to China to invest and build factories. China has become the world's largest processing plant. As a basic equipment industry, it should have a good development prospect.
Domestic heavy-duty machine tool product technology has matured, and the gap with foreign advanced technology is shrinking. Most products can meet user needs. Its manufacturing capacity has entered the forefront of the world, and the manufacturing capacity of foreign heavy machine tool manufacturers is weakening.
Challenges <br> <br> heavy domestic machine tool manufacturers more and more, the market more competitive, will usher in a new round of market reshuffle positioning pattern.
China's machine tool market has become the goal of international competition. The world's machine tool manufacturers are optimistic and will face tremendous pressure from international competition.
Compared with the advanced level in foreign countries, the heavy-duty machine tool products are slightly inferior in technology level, mainly reflected in the level of manufacturing technology and reliability, and become the biggest obstacle to competition with foreign advanced products.
The manufacturing capacity of domestic heavy-duty machine tool manufacturers is very strong, but the main reason is that the processing equipment is backward and the numerical control rate is very low, especially the lack of high-precision processing equipment.
Domestic enterprises have insufficient independent innovation capability, and this situation must be changed rapidly. Because of the market demand characteristics of small batches of heavy-duty machine sheets, the requirements for technological innovation are higher and faster.
