In the “Twelfth Five-Year†development plan of the machine tool industry recently released by the China Machine Tool & Tooling Industry Association, the green manufacturing project including remanufacturing was included in the main scope of work. “Green manufacturing†is a modern manufacturing mode that minimizes the negative impact on the environment and maximizes the utilization efficiency of raw materials and energy. Machine tool products need to be high-performance, high-efficiency, but also save resources, low energy consumption, low pollution, and the processing process should be friendly and pleasant. Therefore, we should start from the design of the product, material selection, manufacturing, use of the process until the product is scrapped and recycled, forming a "green" whole process.
Global environmental factors call for green manufacturing In recent years, the impact of green manufacturing on the international machine tool industry has gradually increased. In particular, since the financial crisis, major machine tool manufacturers have vigorously developed high technology and increased R&D investment to prepare for the next round of industrial upgrading in the post-financial crisis era. At present, the United States has more than 300 enterprises specialized in machine tool remanufacturing, remanufacturing large-scale multifunctional machine tools, gear processing machine tools, and metal Cutting Machine tools, and has established a complete after-sales service and quality assurance system. In Germany, since 1991, the government has allocated a number of grants to support electromechanical remanufacturing to help companies and universities, research institutions, etc. to carry out remanufacturing research. In recent years, Japan has also strengthened the remanufacturing of construction machinery. At present there are at least 20 remanufacturing companies.
The world-famous machine tool manufacturers represented by Demaghe, Yamazaki Mazak, GF AgieCharmilles, etc. have continuously introduced high-efficiency, high-precision, and low-energy-consumption machine tools in recent years. They are very popular with customers and they are also used by other small and medium-sized machine tools. The green manufacturing practices of the manufacturers set a good example.
China's national conditions must be decided to implement green manufacturing. According to incomplete statistics, China's existing machine tools have an installed capacity of 8 million units, making it the world's largest machine tool holder. Among them, more than 2 million traditional old machine tools have been in service for more than 10 years and have entered the peak period of mechanical equipment scrapping. If these old machine tools are allowed to rust and fester, it is not only a waste of resources, but also poses a great threat to the environment.
During the “Twelfth Five-Year Plan†period, China will adhere to the green development and independent innovation of industrial development methods, insist on advocating a green development strategy, and constantly promote the development of ecological, high-efficiency use of capital resources, intensification of production processes, and minimization of pollution emissions. In order to respond positively to the call of the “12th Five-Year Planâ€, pollution-contaminated high-energy-consuming products are now being rejected or heavily taxed. The research and application of low-carbon economy and green manufacturing technologies have made it possible to grasp the direction of economic development in the future. The foundation for entering the international market. Domestic machine tool companies have also taken actions to incorporate low-carbon manufacturing and green environmental protection concepts into their future development plans.
Resource and cost control require green manufacturing From the viewpoint of resource and enterprise cost control, the machine tool industry itself also has strong expectations for remanufacturing. The steel industry in the upper reaches of the machine tool industry is due to iron ore, coke and other steel-making raw and auxiliary materials. It is a non-renewable natural resource, and the iron ore required by China's major iron and steel plants depends on the three major mining giants abroad. In recent years, it has been restrained by steadily rising iron ore prices, steel prices are high, and the cost of downstream machine tool companies remains high. Therefore, the remanufacturing of machine tools is not only conducive to the environment, but also conducive to the reduction of business costs.
Remanufacturing can save energy by 60%, save materials by 70%, save costs by 50%, produce almost no solid waste, and reduce the emission of atmospheric pollutants by more than 80% compared with new products. Remanufacturing is conducive to forming a circular economy model of "resources-products-waste products-remanufacturing products", which can make full use of resources and protect the ecological environment. On the other hand, China's machine tool industry has a rapid growth in social possession, and the remanufacturing industry has great potential for development. A large number of equipment will be eliminated after reaching the scrapping requirements, and new decommissioning equipment is still increasing. The development of the remanufacturing industry is conducive to the formation of new economic growth points and provides the society with a large number of employment opportunities. "Green Manufacturing" of the machine tool in the Action "Opinions on Promoting the Development of Remanufacturing Industry" jointly issued by the 11th ministry of the Central Committee clearly stated that it is necessary to speed up the development of the remanufacturing industry and build a resource-saving and environment-friendly society. The Ministry of Industry and Information Technology has approved 35 companies such as Chongqing Machine Tool and Wuhan Heavy Machinery as remanufacturing pilot companies and requested that the concept of remanufacturing be integrated throughout the entire life cycle of design, production, sales, maintenance, recycling, and remanufacturing.
At present, many universities and research institutes in China have already conducted research in the field of green manufacturing and achieved certain results. For example, Chongqing Machine Tool Group and Chongqing University have jointly formed a set of machine tool remanufacturing and integrated upgrading technologies and completed the remanufacturing of more than 500 waste machine tools. The functions and major technical indicators of remanufactured machine tools have reached or exceeded the original machine tools, and resource cycles The utilization rate is about 80%, the noise is reduced by more than 10%, and the environmental pollution emission is reduced by more than 90%.
At the Beijing International Machine Tool Fair in April, green manufacturing products became a highlight of the show. For example, electrostatic mist eliminator developed by Qinchuan Machine Tool Co., Ltd. greatly improves the treatment effect of oil mist compared with traditional filter-type devices, and the efficiency reaches more than 96%. The discharged air basically reaches a clean degree and the recovered oil mist particles are recovered. Get repeated use. The YS3126CNC-CD CNC high-speed dry-cut hobbing machine developed by Chongqing Machine Tool Co., Ltd. is highly favored by many users because it does not require the green characteristics of the cutting fluid while ensuring high-efficiency, high-quality, high tool durability and high working reliability.
At the 13th Shanghai International Machine Tool Show, many green-made exhibits and technologies have also become the focus of the show. For example, the GE15A ultra-dry cutting high-precision CNC gear hobbing machine exhibited by Mitsubishi Heavy Industries has little impact on the working environment because it does not use coolant. The gear and spline cold extrusion molding machine exhibited by Zhejiang Yuhuan Licheng Special Machine Co., Ltd. has no metal cutting, which not only saves raw materials, but also greatly improves work efficiency.
At present, China's machine tool industry is implementing green manufacturing through four technological measures: low carbon through technological innovation; low carbon through innovative processing technology; low carbon through innovative structure reduction; low emissions through recycling and self-lubrication data.
