Nine development directions of China's medium and high-end CNC machine tools

Over the past decade, the development of the machine tool industry has relied more on sustained and strong domestic market demand, and the role of technological advancement and management upgrades has been relatively limited. Affected by the national conditions, the demand for ordinary machine tools and economical CNC will exist for a long time, but the product life cycle will gradually enter a recession. During the "Twelfth Five-Year Plan" period, the machine tool industry proposed that the development of medium and high-end CNC machine tools is the main point of work. Undoubtedly, the transformation of enterprises, the development model based on scale expansion, and the development of medium and high-end CNC machine tools will be the main focus of the enterprise. direction. Among the metal cutting tools in China, there are fewer roughing machines and more precision grinding machines. In the design of the mainframe, the technology is exquisite, the structure changes more, the various machine tools are complete, the metal cutting machine and the forming machine are more than 3,000 kinds, especially the variety of gear machine tools and tool grinding machines are more complete and the supporting system is the basis. Parts, tools, NC systems and other advanced performance, and a number of world-famous brand-name companies and brand-name products. For example, in the production of hydraulic parts, the variety, series and specifications are complete. In the late 1980s, many countries and manufacturers introduced Chinese products and cooperated. China's machine tools are world-famous. Since 2002, China has become the world's largest machine tool consumer. In 2010, the world's 28 major machine tool manufacturers spent a total of 59.89 billion US dollars, and China's consumption accounted for 45.6%. Because the quality and intrinsic performance of domestic machine tools can not meet the needs of users well, it is still in the unfavorable situation of “low-end melee, high-end failure”, which has led to a sharp increase in machine tool imports in recent years. US$5.01 billion, an increase of 58.3% year-on-year. At present, the market of high-precision products is occupied by developed countries in the West. In the past decade, the development of the machine tool industry has relied more on sustained strong domestic market demand, relatively cheap labor cost advantages and strong support from national industrial policies. Enterprises rely on policy-based natural growth; in comparison, technological progress And the role of management upgrades is relatively limited. According to Luo Baihui, secretary general of the International Model Association, at present, from the perspective of machine tool structure and overall parameters, the medium and high-end CNC machine tools of Chinese and foreign companies are not much different, and the homogenization competition is fierce. The market competition of medium and high-end machine tools has developed into a comprehensive competition of product technology level and enterprise management and management capabilities. Ordinary machine tools have become maintenance tools in industrialized countries such as Europe, America and Japan. Their applications have gradually changed from industrialized production to rough machining and workshop parts repair. Economical CNC machine tools are unique to China, and are upgraded products of ordinary machine tools. limited. Affected by the national conditions, the demand for ordinary machine tools and economical CNC will exist for a long time, but the product life cycle will gradually enter a recession. During the "Twelfth Five-Year Plan" period, the machine tool industry proposed that the development of medium and high-end CNC machine tools is the main point of work. Undoubtedly, the transformation of enterprises, the development model based on scale expansion, and the development of medium and high-end CNC machine tools will be the main focus of the enterprise. direction. 1. Taking the market as the starting point, product management should take the market as the starting point, serve the target customers, and focus on developing medium and high-end CNC machine tools such as CNC, Liga, Tijia, Longmen, CNC, CNC grinding machines with large market capacity and strong development potential. We must not blindly pursue the novelty of mechanical structure and the high precision index. Taiwan's machine tool companies mostly position their products on a large number of mid-range CNC machine tools. Although they are technically different from Germany and Japan, they are economical and practical, and can meet the needs of most users. Machine tool enterprises have achieved an average annual rate of 30%. ~40% growth. In recent years, Mori Seiki launched the X series, DMG launched E series and other economical CNC machine tools, all of which are slightly lower in price, economical and practical, and entered the domestic market. Sales in China have achieved rapid growth. Product development should highlight the selling point of machine tools. Take the X series of Mori Seiki as an example. The X series involves NLX CNC, NVX Liga, NHX and NTX. The main features of the four main models are high rigidity, thermal deformation symmetry, and energy saving. Environmental protection, rich models, etc.; each machine has its own characteristics, NLX CNC car total power consumption reduced by 30%, lubricant consumption reduced by 15%, NVX vertical high rigidity three-axis slide fast-moving speed 30m / min , NHX horizontal plus high-speed high-precision fast-moving speed of 60m / min, positioning accuracy of 2.5μm, NTX composite machine high-precision and efficient use of unique technology DDM, ORC and BMT, machine width reduction of 1m, footprint reduction of 30%. 2. Master plan, adjust the product structure, sort out the existing products of the enterprise, plan the machine model spectrum as a whole, make great efforts to adjust the product structure, and do not pursue the product line to be large and complete. It is necessary to analyze the profitability of the main products and focus on the development of scale. High-end CNC products with strong profitability and elimination of unprofitable products. Implementing quality projects, combining the company's product sales, profit levels, technology levels, product stability and other comprehensive factors, analyzing market conditions, trends and business reality, focusing on limited resources, focusing on the most successful and promising On the main products, we will create a boutique to form a leading brand, and lead products with leading products to form a superior machine tool product in the segmentation field. For enterprise management, it is not as good as less, less as good as fine. If the enterprise seeks long-term development, it is almost impossible to rely on a chaotic multi-product strategy. To learn Taiwan's machine tool industry, whether it is a main engine factory, a functional component factory or a supporting factory, the product technology is mature and the quality is stable, and each family has expertise. 3. Collaborative design to improve the standardization and generalization level CNC machine tools are integrated machine tools that combine electronic information technology with traditional machine tool technology. They integrate mechanical, electrical, liquid, gas and other engineering disciplines and are systematic projects. The product design should implement the collaborative design of production, supply and sales, and realize the control of machine tool cost with reasonable design. Product design is the source of the production organization of the enterprise. All production activities are carried out according to the drawings and processes. Therefore, the product quality, cost and delivery time are determined by the product design. The main structure, dimensioning and tolerance of the product design. The selection of components and parts should be standardized as much as possible. In product development, designers should take the initiative to consider whether parts with similar shapes or functions can be made universal. Universality and modularity can satisfy the individualized needs of users and speed up the delivery process. The production and sales of general-purpose parts are large, which is convenient for workshop organization, which can greatly improve the efficiency of processing and assembly, and the bulk ordering also reduces the procurement cost. Generalization is the foundation of standardized operations, and standardization can not only improve efficiency but also stabilize product quality. 4. Process standardization to improve product quality "If you want to do something good, you must first sharpen its tools." Any product that has a high level of product quality should have advanced process standards. The production process runs through all aspects of production, and the process documentation ensures the orderly conduct of production activities, achieving goals such as improving product quality, reducing production preparation, reducing costs, and increasing labor productivity. Therefore, for enterprises to have good product quality, process assurance is a real content. The young employees of the machine tool enterprise after 80s and 90s are the main force of processing and assembly, and the lack of work experience leads to the instability of product quality. Standardized operations are the most effective way to solve this problem. The lean manufacturing concept of standardization, graphicization and data is constantly explored by machine tool companies. For the assembly site of DMG, the craft manual and the drawing board are ready for the workers. Pay attention to the details, taking the installation of linear guides as an example, strictly refer to the drawings, process requirements and standardized operation instructions. Use the torque wrench to install the rail clamps and guide rails in place under the specified torque, and mark them separately. Maintenance and adjustment in the future. At the assembly site of many industrial enterprises, after the workers are looking for the watch, only the ordinary hex wrench is used to tighten the guide rail and the clamp. 5. Pregnancy of the future, increase the research of basic theory Through years of development, domestic machine tool enterprises have mastered the basic mechanical structure of CNC machine tools, and can initially predict that the main mechanical structure of CNC machine tools will not change greatly in the next 10-20 years. In the future, CNC machine tools will develop to high precision and high efficiency. Therefore, high-efficiency functional components such as electric spindles and linear motors will be applied to the transmission system. The control technology is especially based on INTERNET-based remote maintenance and management, five-axis linkage control technology, and ergonomic operation. Technology, thermal deformation and compensation are the focus of machine tool technology development. Machine tools as a comprehensive discipline, the basic theory of research only depends on their own, the basic theory of research involves machine tool structure, vibration control, temperature control, noise control, tool applications, CNC system applications, dynamic control and many other fields, these aspects are currently in the actual machine tool enterprises The application is still blank. In addition, five-axis control technology, spindle system, feed system, numerical control system, electrical control aspects of functional components research has not been a substantial breakthrough in China, the key technology has not yet mastered, only independent research and development can break through key technologies. 6. Stabilizing the quality and improving the quality of the single machine The first step is to stabilize the quality of the single machine and improve the quality. It can be seen from the large number of imported high-end machine tools from domestic users. The imported machine tools are only slightly better than the domestic enterprises, and the users are not afraid to spend a lot of money. The quality of imported machine tools is concerned with the accuracy and reliability of the products. Compared with the international advanced level, there are still large gaps in the processing precision, reliability, efficiency, automation, intelligence and environmental protection of Chinese machine tools. The accuracy of the machine tool of foreign processing center is according to the German VD13441 standard, the stroke is less than 1000mm, the positioning accuracy can be controlled within 0.006~0.01mm, while the domestic is relatively low, the control is 0.01~0.02mm; there is a significant gap in the reliability of the machine tool, and the average is faultless. Time (MTBF) foreign machine tools are more than 5000h, and domestic machine tools are much lower than this number. The overall deficiencies focus on key manufacturing levels, machine tool accuracy and stability, machine tool mean time between failures, and basic research in machine tool applications. 7. Carefully manufactured, implement total quality management, strictly abide by the process specifications, implement total quality management, and learn Toyota's Total Quality Management (TQM), emphasizing that quality is produced rather than tested, and is guaranteed by quality management in production. The final quality of the product. At the time of each process, attention is paid to quality inspection and control to ensure timely quality problems and to cultivate employees' quality awareness. When problems are found, production is immediately stopped until it is resolved, and the next process of unqualified and problematic products is avoided. Choose a manufacturer of purchased parts and spare parts. Qualified raw materials are the material basis for producing quality products. The machine tool must use high-performance, high-reliability numerical control system, servo drive device, supporting functional components, electrical components, and detection components to ensure machine reliability. It is necessary to strengthen the management of purchased parts so that the quality of their products is within the controllable range. 8. Continuous improvement Continuously improve the intrinsic quality of products. Only after continuous improvement, continuous improvement can make up for design defects, improve the production process route, sum up experience in practical application, and continuously improve the intrinsic quality of products. In the 50 years from 1950 to 2000, the machining accuracy has increased by about 100 times, that is, the machining accuracy has doubled every 8 years. The current general machining accuracy has reached the level of precision machining in the 1950s. The processing methods and manufacturing levels are constantly updated, and the needs of users are also increasing. The auto industry is updated every six months. The international machine tool enterprises basically update their products once every two to three years, while the main structure and performance upgrade of domestic machine tool products are slow, and many parts have not been greatly changed after the structural design, and they have been used ever since. Continuous improvement can make up for the inadequacy of design, adapt to modern design, process manufacturing level, it can be said that continuous improvement is the same important technical work as new product development. 9. In-depth study of customer process research The first goal of the development of the machine tool industry during the “Twelfth Five-Year Plan” period is to make breakthroughs in providing equipment and services for key manufacturing industries. Aerospace, marine, automotive and power generation equipment manufacturing is the most important service area in the machine tool industry and is a typical high-end market segment. The purpose of the customer's purchase of equipment is to make profits for production. Luo Baihui believes that during the “Twelfth Five-Year Plan” period, industry enterprises should focus on the product and process requirements of high-end customers and large customers, tailor-made according to customer needs, and provide customers with services. Personalized service required. In particular, it provides production lines for mass production users, equipped with technical services, and implements turnkey projects. The “turnkey” project of the machine tool industry is mainly embodied in the complete set of solutions for parts processing according to the user's process requirements and production program. It not only provides users with a single machine tool, but also includes machining processes, machine tools, fixtures, tools, Inspection and measurement, software and many other connotations. In this regard, we should focus on the customer process research of HAAS in the United States. HAAS machines regularly launch magazines to introduce the actual application of their products from the user's point of view; the mobile platform website provides users with a list of Haas models, descriptions, specifications and price information. Built-in advanced tool management (ATM) features greatly simplify the task of specifying, calling and managing spare tools.

Geotextile- woven and nonwoven Geotextile

Geotextiles are available as woven and non-woven .As liner protection, against physical damage, the non wovens are normally the answer.They are made up of fibers of polyester or polypropylene in random directions and punched together by needles during the manufacturing process.Geotextiles are commonly used to separate layers like clay and drainage and to protect liner from damage.

Geotextile is a non-woven product manufactured by combinining synthetic short yarns mechanically by using needling method. Non-Woven Geotextile has no woof and warp. Strength is achieved by combining yarns and applying thermal process. Geotextile felt is a permeable textile product which can be used with basic elements or with any material related with soil, running ground or geotechnic engineering.
