In the face of the various heavy-duty machine tool companies that have sprung up since the financial crisis and competition from similar products, the old heavy-duty machine tool companies have shown calmness and calmness. At the same time that emerging companies are still using low-end products as paving stones to enter the heavy-duty machine tool industry, the old leading enterprises have been focusing on high-end products, the first set of first, major special projects, key equipment, and alternative imported products. In the research and development of technical products, the old leading companies have contributed. At the same time, going abroad to open up the international market, let Chinese machine tools go to the world, show the strength of Chinese manufacturing, has also become the important task of these leading enterprises.
Pick the beam high-end products
Under the cultivation of the market and the promotion of relevant national policies, the research and development of heavy-duty machine tools in China has achieved commendable results in recent years. The demand for heavy-duty machine tools is mainly concentrated in key industrial enterprises such as energy, transportation, shipbuilding, machinery, metallurgy, aerospace, military, etc. Therefore, these heavy-duty machine tool enterprises are responsible for the equipment manufacturing industry in China, and they have repeatedly built in some major engineering projects. Meritorious, become a model for Chinese equipment and equipment for China.
At Shanghai Machine Tool Works Co., Ltd., representatives of Shanghai Heavy Machinery Co., Ltd. are in the process of accepting an ultra-heavy precision CNC roll grinder. MKA84250/ 15000-H ultra-heavy precision CNC roll grinder meets the workpiece support at the tip of both ends for grinding, achieving high-precision grinding of rolls up to 250 tons in diameter, 2.5 meters in maximum diameter and 15 meters in maximum length, while ensuring high height The rotation of precision. The equipment can not only meet the needs of shipbuilding for large-scale steel plate rolling, but also can be used for the development of large-scale grinding machines such as large-scale crankshaft grinding machines for ships. It is listed in the national science and technology major project and fills the domestic gap. Its successful development marks that the R&D and manufacturing of China's ultra-heavy precision CNC roll grinders has entered the world's advanced ranks.
In the heavy workshop, the world's largest 6.3-meter heavy-duty CNC lathe is officially off the assembly line. The equipment can be used for the processing of large-scale shaft parts of ships, power generation equipment, metallurgical equipment, etc., mainly to meet the rough and fine processing requirements of the core components of large-scale nuclear power equipment and hydropower equipment in the national key energy industry. Its maximum processing diameter is 6.3 meters, and the maximum weight of the workpiece is 200 tons. Whether it is the largest processing diameter or the load-bearing machine tool, it has reached the highest in the world. The bed box with a height of nearly 5 meters and the length of the bed with a length of 20 meters are in heavy machine tools. It is rare.
In today's world, ultra-heavy-duty CNC milling and boring machines with a diameter of 320 mm for the machining of very large parts can only be manufactured in a few countries such as Germany and the Czech Republic. China's ultra-heavy CNC milling and boring machine mainly relies on imports. Not long ago, from Qi 2 machine tool, the first, the world's largest, completely independent research and development of the TK6932 super heavy double column vertical CNC floor milling and boring machine was successfully developed in Qi 2 machine tool, is preparing to ship to its user unit CITIC Heavy Industry. The equipment has completely independent intellectual property rights, and various technical indicators have reached the international advanced level. It can process large-scale workpieces such as aerospace, large-scale mining machinery, large-scale hydropower units and nuclear power plant equipment, breaking the monopoly of Western technology and filling the domestic gap. It has ended the long history of extreme processing and manufacturing equipment for extra large parts in China, and has provided valuable experience for the extreme manufacturing of other ultra-heavy CNC machine tools in China.
This is just a few examples of many of the advances in China's heavy-duty machine tool manufacturing technology. In fact, after years of product and industrial restructuring, China's heavy-duty machine tool companies have made great progress in product specifications and product functions. China's heavy-duty machine tool products are developing towards high-end CNC new products with multi-functional composite processing, and have achieved gratifying results in meeting the individual needs of users, new technology research and new product development.
Cultural heritage into a competitive advantage
There are more and more domestic heavy-duty machine tool manufacturers. Both domestic-funded enterprises and joint ventures, as well as domestic-funded enterprises that have acquired famous foreign manufacturers and the entry of private capital, have made the competition in the heavy-duty machine tool market increasingly fierce. However, for this kind of competition, the person in charge of Wuzhong only took a smile, because in this market they are not familiar with, the price is definitely not the only factor that prevails.
Wu Zhong’s relevant technical person in charge said in an interview, “For heavy-duty machine tools, the company’s heritage and cultural heritage are very important. The life cycle of heavy-duty machine tools is very long, which requires high stability and accuracy. Therefore, the accumulation of technology is very important, but the technology is not enough, because the design of the drawings, there are problems with the process."
Nowadays, many private capitals dare to invest in the field of heavy-duty machine tools because of the drawings, but in fact the problems of the process are much more difficult to solve than the drawings. The formation of the entire process route, as well as the configuration of the process equipment, requires scientific research engineers and technicians to work in this industry for decades, and then there will be mature ideas.
For example, what materials and parts of many parts of heavy-duty machine tools are used, the appearance is not visible, but the essence may be different. The person in charge of Wuzhong gave an example, like the claws on the vertical car. Some enterprises may be simply processed. After the speed is up, there may be a break. Mature processes require that the jaws be forged and heat treated after forging.
Therefore, the setting of the process route and the configuration of the process equipment are not mastered in a short period of time. This is actually a accumulation and inheritance of the enterprise. This is precisely what some later companies can't match, although the person in charge of Wuzhong said that the entrants will become more difficult to market, but as long as the user really understands the machine tool, even if the price is more expensive, he will choose Wuzhong's products. And in the marketing to give users a deeper understanding of the characteristics of heavy-duty machine tools.
Going abroad to showcase Chinese manufacturing
Over the years, we have only seen high-end machine tools imported from China, including Germany and Italy, which represent the world's advanced level. Some professionals pointed out that the difference in structure between domestic products and foreign products is not large, and the new technologies used are also similar. The biggest difference is the running speed, accuracy and reliability of the core transmission components, and the manufacturing process level of the entire machine tool. Quality, this is the biggest advantage of foreign products.
Nowadays, heavy machine tool companies led by established state-owned enterprises are quietly reversing this situation, realizing the landing of domestic high-end heavy-duty machine tools to machine tools such as Europe, America, Japan and South Korea. After several days of careful "pricking", the craft engineers of the Sheffield Forging International Company of the United Kingdom left Wuzhong with three machine tools satisfactorily. Sheffield Forging International has more than 200 years of manufacturing history and is one of the world's leading producers of refined steel castings and forgings. Its products are widely used in key industries such as defense, nuclear power, oil and natural gas exploitation. Therefore, there are high requirements for the equipment they purchase. Affected by the financial crisis, foreign heavy-duty machine tool manufacturers suffered heavy blows. In order to survive and increase prices, upstream manufacturers could not afford the cost increase and went to foreign countries to find production partners. In this context, Sheffield Global Tender. With its high-quality products and perfect service system, Wuzhong has won the favor of the British. Qi Er Machine Tool achieved a substantial increase in the export of machine tools to South Korea last year, and the export volume broke through 10 million US dollars. At the same time, they are also actively exploring the South American market. Even some private machine tool companies have achieved a historic breakthrough in the export of mid-range products to Europe. The leading role of the established companies can not be underestimated.
Realizing the export of high-end products to machine tool manufacturing powers, representing China has made great progress in the manufacture of heavy-duty machine tools, both in terms of application technology level, manufacturing process level, product quality, and after-sales service quality have reached world-class levels, and It has been widely recognized by international users. China-made machine tools are sprinting to the world under the leadership of heavy-duty machine tool pillar companies, showing the world the technical strength of China's machine tool manufacturing.
