High-end machine tool "green remanufacturing"
Regarding green manufacturing, there have been many articles published in domestic newspapers and magazines recently, and there are quite a few companies actually invested in it, forming a strategic emerging industry with considerable scale.
However, there is little mention of high-end machine tools "green remanufacturing". There are three reasons for this: First, compared with ordinary machine tools, the number of high-end machine tools is negligible, and it is scattered in all walks of life, not too noticeable. Second, the high-end machine tools are complex in structure, high in precision, and technically difficult. "Remanufacturing", the general machine tool enterprises do not dare to do, can not do, do not work well; the third is high-end machine tools "green remanufacturing", often a single piece of production "one thing one discussion", a large output, cost-saving, limited benefits, large Machine tool companies organize production troubles, do not look up, do not want to do, may not be able to do well.
It is against this background that Jiangsu Chenguang CNC Machine Tool Co., Ltd. is the first in China to propose a new concept of “green remanufacturing” for high-end machine tools.
The machine tool "green remanufacturing" is a new machine tool manufacturing model that makes full use of the existing waste machine tool resources. It is essentially different from the traditional machine tool scrapping process and the old machine tool overhaul. It is a full use of modern advanced manufacturing technology and information technology. High-tech, numerical control and automation technology, green manufacturing technology, and other high-tech remanufacturing evaluation and disassembly of used machine tools, as well as innovative redesign, remanufacturing, and reassembly processes. The goal is to remanufacture the original machine tool in a larger scale. New machine tools with better functions and better performance indicators. Machine tool remanufacturing can fully exploit the usable value of waste machine tools, and it is the industrialization repair and transformation of high-tech machines for used machine tools. Machine tool remanufacturing can make full use of the old equipment resources, obtain high-performance CNC machine tools at a small cost, improve processing efficiency and processing quality; can comprehensively improve the existing machine tool performance of enterprises, and effectively improve the processing and manufacturing capabilities of enterprises. At the same time, it can save a lot of energy consumed during casting and cutting, and reduce environmental pollution.
Since the 1950s and 1960s, especially since the reform and opening up, with the advancement of China's four modernizations, aerospace, military, maritime, railway and other departments as well as large state-owned enterprises and central enterprises have been developed from Europe, the United States, Russia and Japan. A high cost, high-end, precision, and automated processing machine tools have been purchased at a high cost, which has greatly contributed to the improvement of China's overall manufacturing technology.
However, like people, high-end machine tools will age, control technology aging, control components aging, and structural aging. Many of the equipments are old, long-term, difficult to repair, old-fashioned, lack of arms and legs, close or have been scrapped. For these high-end machine tools, the traditional solution is nothing more than downgrade use, major modification, and scrap update.
Let's talk about downgrading, which is often for imported equipment that is not used for a long time and can continue to be used. Since it is used for downgrading, it indicates that its processing accuracy and efficiency have been difficult to meet the requirements. "It is a pity that it is tasteless and discarded," and it is reluctant to update. For such machine tools, if the "green remanufacturing" method is adopted, it is still possible to restore youth by finding out the right medicine for the problem. Such an approach does not cost much, and the amount of renovation work is small, with quick results and good results.
In addition to the large modification, the traditional large-scale modification is nothing more than partial repair of mechanical parts, restoration accuracy, replacement of components of electronically controlled hydraulic components, or a small-scale improvement of structure, or the replacement of general-purpose equipment into special equipment. Due to the uneven technical strength of various enterprises, some imported machine tools are too old. This method can only be partially changed, and it is impossible to restore or improve the performance of the equipment as a whole.
As for scrapping, of course, the final destination of any equipment. However, from the perspective of “green remanufacturing”, the basic components of these machine tools, such as bed and workbench, can still be used, and these large parts are used for a long time, and the internal stress is eliminated more thoroughly. The “green remanufacturing” approach has turned into a new machine tool that is better than the new machine tool and avoids wasting resources.
Therefore, the “green remanufacturing” of high-end machine tools is a new road to transformation that meets Chinese characteristics.
