The requirements of the "Twelfth Five-Year Plan" plan will strengthen planning guidance, pilot demonstration, industrial agglomeration, technological innovation and system construction, and promote the re-manufacturing industry to form a larger scale. The Development and Reform Commission will continue to strengthen coordination guidance and support for auto parts remanufacturing pilots, promote remanufacturing of construction machinery, machine tools and other large tires, encourage the development of new remanufacturing service industries, and focus on cultivating typical demonstration enterprises for remanufacturing. Machine tool remanufacturing entered the golden period Since the early 1980s, countries around the world have developed the machine tool remanufacturing industry. At present, the machine tool industry in developed countries such as the United States, Japan and Germany has been sluggish, but machine tool transformation has become a new growth point. Here are a few examples of old machine tool modifications. German CNC pentahedron processing machine tools, due to overdue use, hydraulic system aging, the basic large parts wear and tear, the accuracy is basically lost, almost on the verge of retirement. Re-purchase, the cost is as high as 32 million yuan; continue to use it, machine tool failures frequently occur, often dragging the production of hind legs. Last year, the Nanjing factory tried to contact Wuhan Huazhong Automation. Completely dismantle the fuselage, replace damaged and worn parts, replace the new "heart" of Siemens CNC system, install the self-developed machine operation monitoring system... After a few months, this old machine tool was reborn. The cost of the calculation was only 8 million yuan. After several months of operation, we have achieved high performance and high precision design requirements. Zhang Junan, general manager of Huazhong Automation Co., said that the old machine tools generally have a residual value of 45% to 80%, mainly the bed, column and base with strong durability. Remanufacturing these body parts requires a lot of steel and energy. If the main body is retained, repaired or replaced, damaged equipment can be manufactured with the same quality or even better performance as the new equipment. It is a myth that refurbished machines will perform better. In Wuzhong Group, we opened our eyes: after a smashed former Soviet roll lathe in WISCO “had a roll†here, it not only improved the accuracy of the machine tool, but also raised the main bearing weight from the original 20 tons to 30. Ton. Using modern numerical control technology, the planer can be turned into a CNC gantry milling machine, or a CNC gantry grinder. At the same time, the energy consumption of the equipment after the transformation is reduced by nearly 40%, achieving the purpose of energy saving, reducing consumption and reducing emissions. In recent years, the province's Wuzhong, Maxima, Huazhong Automation and other companies have fully launched scientific research and exploration of mechanical and electrical products remanufacturing. According to the Provincial Economic and Information Committee, in recent years, these enterprises have taken advantage of the professional advantages of heavy-duty machine tools, engineering machinery, large-scale CNC machine tools, etc., to give a large number of machine tools a second life, and also played a well-known brand in China. In the Gucheng County Renewable Resources Park, Jinyang Company and the nearby camel battery company jumped into the "circle dance" - Jinyang Company used lead-containing waste and waste lead-acid batteries, with an annual output of 400,000 tons of lead and lead alloys, supplied to camel batteries. The company; and the lead-acid battery recovered by Camel Company returned to Jinyang Company. Machine tool remanufacturing entered the golden period Since the early 1980s, countries around the world have developed the machine tool remanufacturing industry. At present, the machine tool industry in developed countries such as the United States, Japan and Germany has been sluggish, but machine tool transformation has become a new growth point. There are more than 300 companies specializing in machine tool remanufacturing in the United States. The classification is extremely fine. There are professional companies responsible for remanufacturing large-scale multi-function machines, gear processing machines and metal cutting machine tools, and provide after-sales and warranty. Since 1991, the government has repeatedly allocated funds to support electromechanical remanufacturing, helping companies to carry out remanufacturing research with universities and research institutions. In recent years, Japan has also strengthened the remanufacturing of construction machinery, and at least 20 remanufacturing companies have become large-scale. About 30% of Japan's remanufactured construction machinery is exported to foreign countries. Europe and the United States have formed a relatively complete old parts logistics system. The remanufacturer recycles the used machine tools through various channels, evaluates the value, redesigns, and manufactures the “remanufacturing†label and re-enters the market. China is the country with the largest number of machine tools. At present, there are more than 2 million traditional old machine tools with more than 10 years of service. It has entered the peak period of mechanical equipment scrapping, and the market for remanufacturing is huge.
