Tool industry innovation and transformation are inseparable from product structure adjustment
Today, when we are preparing for the implementation of the "Twelfth Five-Year Plan", we will review the important achievements related to the equipment manufacturing industry during the 11th Five-Year Plan period. We will definitely feel that we are engaged in cutting and tool manufacturing. The industry shoulders major responsibilities during the 12th Five-Year Plan period and is fully prepared for the challenges and opportunities that will be encountered. First, look at the status of the large user automotive industry of tools. In 2009, China's automobile production reached 137.91 million units, surpassing Japan for the first time to become the world's largest automobile production country. From January to September 2010, China's automobile production and sales exceeded 13 million units, and it is expected to exceed 17 million units in the whole year. More than 3 times. The "Twelfth Five-Year Plan" predicts that by 2015 China's automobile production will reach 20-25 million vehicles. The development of the automotive industry is closely related to cutting and machining. Look at the energy industry. First of all, the Three Gorges Project, which has attracted worldwide attention for 18 years, has been basically completed by the end of 2010. Among them, 26 sets of 700,000 kW generator sets are all connected to the grid for power generation. In the field of wind power, as of 2009, China's newly installed wind power installed capacity reached 13.8 million kW, surpassing the United States, becoming the world's number one in terms of new wind power installed capacity in the year; it will reach 230 million kW in 2020, equivalent to 13 Three Gorges power stations. In the field of nuclear power, on October 20, 2010, China's first Qinshan Nuclear Power Phase II project (Unit 3), which was designed and built by China, was put into commercial operation. So far, there have been 4 nuclear power bases put into commercial operation in China, and the number of nuclear power units has reached 13 The installed capacity is 10 million kW; by 2020, the installed capacity of nuclear power in China will reach 40 million kW. The energy industry will have a great demand for advanced tools. In recent years, the rapid development of China's high-speed train technology has received great attention from all over the world. With the opening of the Shanghai-Hangzhou Expressway, the high-speed railways in operation in China have reached 7,431 kilometers, ranking first in the world; Beijing-Shanghai high-speed railway in 2011 After opening to traffic, China's high-speed railway will reach 13,000 kilometers; by 2020, it is expected to build a high-speed railway network of 16,000 kilometers. The leading edge and development momentum of China's high-speed railway has provided new opportunities for the tool industry. In the aerospace field, four AJR21 civilian regional aircrafts with independent intellectual property rights have been put into flight test, with a cumulative flight time of more than 600 hours. The first aircraft is scheduled to be delivered to users this year. The development of the long-awaited domestic large-scale aircraft C919 is progressing rapidly. It will be the first flight in 2014 and will be delivered to users in 2016. This will gradually end the long-term dependence of China on the import of large foreign civil aircraft. In the aerospace industry, during the "Eleventh Five-Year Plan" period, China successfully launched the Yan 1 and No. 2 lunar spacecraft and became the fifth member of the World Lunar Club. China will realize manned landing on the moon around 2025, and the dream of Chinese people on the moon is becoming a reality. The processing of difficult materials and synthetic materials in the aerospace industry is the commanding height of cutting technology, which will drive China's cutting and tooling technology to a new level. Through these examples, we naturally think of the fact that the processing efficiency of mechanical parts such as automobiles, locomotives, generator sets of various power stations, aerospace vehicles, and the quality of machining are directly dependent on the cutting performance of the tool. In the equipment manufacturing industry, the development of many new products and the application of new materials are also indispensable for cutting process and tool innovation. It can be seen that the development and progress of many important industrial sectors in the national economy are inseparable from cutting technology and tools. On the other hand, it is also the strong demand for manufacturing development, which promotes the rapid development and innovation of cutting processing technology. Therefore, along with the development of the manufacturing industry, the development and innovation of cutting technology and cutting tools have also made great progress. After the development from the end of the last century to the beginning of this century, from a global perspective, cutting technology has entered the development stage of modern cutting technology, and has revealed the obvious features of modern cutting technology, including: comprehensive improvement of cutting technology level, cutting The processing efficiency has been doubled; new cutting processes and new machining methods such as high-speed cutting, high-efficiency cutting, hard cutting, and dry cutting have been developed, breaking through the traditional cutting process; the structure of the tool product is fully updated: hard alloy As the main tool material, the proportion of coated tools has increased significantly, the proportion of indexable tools has increased, and the standard general-purpose tools for solid carbide have entered the practical stage, and the application volume has been increasing; the innovation speed of the tools has been greatly accelerated, new grades, New coatings and new structures are constantly emerging, the whole industry is full of vitality; the connotation of cutting technology is expanding, the application of materials science and computer technology is significant, and the importance of tool application technology is increasing; the tool industry has established “oriented to manufacturing, facing "User" business philosophy, completed from the traditional tool industry Modern transformation tool industry, the formation mechanism of sustained and rapid development of the tool industry. From the current situation of China's tool industry, on the one hand, we have made great progress in the above six aspects, and made important contributions to the development of China's manufacturing industry, but compared with the advanced level of foreign countries, and advanced manufacturing. There is still a certain gap compared to the requirements for high performance tools. The main gap is in the adjustment of product structure, tool innovation and industry transformation. We must make new progress during the “Twelfth Five-Year Plan†to meet the needs of the tool industry in the “Twelfth Five-Year†development plan, and for Long-term development lays the foundation. The adjustment of the product structure is now the era of cemented carbide as the main tool material. Compared with high-speed steel, cemented carbide has better performance and higher cutting efficiency. It is a modern cutting technology together with super-hard tool materials. The most important guarantee of efficiency. The proportion of cemented carbide tools in China is about 40%, which is far lower than that of industrial developed countries, which restricts the improvement of the overall level of China's tool products. Without good tool materials, any tool innovation and cutting process development lacks the necessary material basis and can only be a castle in the air. However, to fundamentally solve this problem, involving the adjustment of the industrial structure, in addition to the existing Zhuzhou Diamond Cutting Tool Co., Ltd., it is necessary to speed up the construction process of the production base with hard alloy materials and tool research and development capabilities, and rapidly increase the hardness. The specific gravity of the alloy tool in all tools. This is a major investment project that requires the support and operation of relevant government departments. The innovation of cutting tools is worthy of attention. The innovation of modern cutting tools is manifested in three aspects: The first is the innovation of material grades, which accounts for a large proportion of current tool innovations, especially the development of cemented carbide and superhard materials. A large, comprehensive company that launches a number of new grades each year and is a major selling point for their new tooling products. The idea of ​​its development is based on the characteristics of the application field, the advantages of integrated materials, coatings and troughs, and the development of “the right medicineâ€, which makes the blade show performance advantages in a certain range of applications, resulting in good processing results. Generally, the processing efficiency can be increased by more than 20%. It can also be seen that we must accelerate the process of building a cemented carbide R&D and production base. The second is that coatings play a large role in tool innovation. Tool coating technology has evolved very rapidly since coating technology entered the tooling field. As the coating process, equipment, and component innovations continue to accelerate, its ability to modify the tool is also increasing. Due to the remarkable effect of coating technology on improving the performance of the tool, the flexibility of the process, and the rapid development of new grades, not only the cutting performance of the tool is greatly improved and improved, but also the innovation of the blade coating grade is Fast and good. Coatings have become the most important factor driving advances in cutting technology. Up to now, China does not have the ability to independently develop tool coating equipment and processes, which restricts the progress of cutting technology in China and the innovation of coating grades. It is imperative to vigorously develop tool coating technology. The third is the strong momentum of the tool structure, showing great potential. We have had an era of vigorous tool innovation, and we have gained a good reputation for the reputation of the tool. Later, we entered a low-end period of tool innovation. Everyone made the so-called stereotyped products of the same structure according to the drawings of the joint design, and at the same time they all carried out the standard universal tools of thousands of times. With the development of computer-aided design and numerical control manufacturing technology, it provides a strong material foundation for the innovation of tool structure, and usher in a new era of tool innovation. At present, the momentum of tool structure innovation is very strong, and the new tool structure introduced by various tool companies has become the highlight of the machine tool exhibition in recent years. The innovative tool structure not only improves the tool performance, but also has a great impact on the development of the tool variety. For example, the milling cutter structure can greatly expand the function of the milling cutter and reduce the time for tool change. The structural features have been extended to different types of milling tools, forming various milling cutters that can be ramp-milled. Promoted the development of milling processes and milling cutters. Another example is the large-feeding small-cutting deep-cutting cutter, the unequal-spiral vibration-reducing end mill, the light-vehicle blade, the threaded turning tool with the guide rail on the bottom of the blade, the contouring turning tool, the internal cooling structure of the cutter, etc. enumerate. As soon as each new tool emerged, it caught the attention of the industry and was quickly promoted in the industry, which played a significant role in developing the variety of tools to improve the performance of the tool. Many tool companies in China only make tools that do not produce tool materials, and should pay more attention to the innovation of tool structure. At present, there is still much work to be done to accelerate China's tool innovation. In addition to the need to update the equipment hardware, we must pay attention to the following two aspects of work. On the one hand, it is to improve the basic knowledge of metal cutting in the tool industry, including design, manufacturing, marketing, service and other aspects of personnel. For the innovation of grades and coatings, professionals engaged in materials and coatings must master the basic theory of metal cutting and become a compound talent. Pay attention to learning tool application technology, especially development, marketing and field service personnel. Without knowing the requirements of the tool and not analyzing and solving the problems in use, it is difficult to innovate the tool. The innovation of cutting tools must be based on the mastery and application of basic knowledge, we must strengthen this aspect of learning. Enterprises should organize their own classes or participate in classes held in the society, which should be valued and utilized. The other is the transformation of the tool industry. We must complete the transformation from traditional tool manufacturers to “manufacturing-oriented, user-oriented†manufacturing cutting technology service providers and processing efficiency suppliers. “Managing for the manufacturing industry, facing the users†is the modern tooling (enterprise) industry. symbols of. To this end, we must be familiar with the technological characteristics of the cutting process in the important industrial sectors of manufacturing, the main workpiece materials, production models, development direction and product development, so as to correctly and timely determine the development direction of their products and become the driving force for innovation. Many tool companies in China have achieved such transformations to varying degrees, and have achieved certain results, but also need to increase their efforts. Serving the users is a basic skill that must be possessed by the modern tool industry. Only through service can the first-hand information of tool innovation be obtained. As a tool for productivity, tools can only continue to find problems and innovate in applications. In addition, new user demand information can be obtained in advance. The transformation of the industry also needs the support of the government. When determining the major projects, the state should hand over the research and development of supporting cutting technology and tools to the tool industry to improve the ability of the industry to serve the manufacturing industry. In the same year, in line with the construction of Shanghai Baosteel, for the processing needs of large rolling mills, gears, etc., the development of heavy-duty tools by the tool industry has played a very good role in promoting the development of the industry.
