The vertical machining center of high end machine tool "green remanufacture"

About green manufacturing, a lot of articles have been published recently in the magazine of vertical processing center of China's newspapers and magazines. Actually, many enterprises actually invest in it, and are forming a strategic emerging industry with considerable scale.

However, there is little mention of the "green remanufacturing" of high-end machine tools. There are three reasons: one is the high-end machine compared with ordinary machine number not worth mentioning, and scattered throughout all walks of life, not too noticeable; two is the high-end machine complex structure, high precision, high technical difficulty, "green manufacturing", the general machine tool enterprises do not dare, do not do well; three is the high-end machine "green manufacturing", are often single production of "thing", large output, tax and benefit is limited, large machine tool production enterprises in trouble, disdain, is not willing to do, not necessarily do well.

It is in this context that Jiangsu Chenguang NC Machine Tool Co., Ltd. has put forward the new concept of "green remanufacturing" of high-end machine tools in China.

The machine "green manufacturing" is a new mode of making full use of the existing resources of the waste machine tools with traditional machine scrap and old machine overhaul is essentially different, is a full use of modern advanced manufacturing technology, information technology, numerical control and automation technology, green manufacturing technology the technology of waste machine Remanufacturability evaluation and disassembly process and the innovative design, manufacturing, assembly, and its goal is to scale to create new machine is better than the original machine has stronger function and performance index. The remanufacturing of machine tools can fully excavate the available value of the waste machine tools, and it is the industrialization repair and transformation of the high and new technology for the waste machine tools. Machine remanufacturing can make full use of old equipment resources, and acquire advanced CNC machine tools at a relatively low cost, improve machining efficiency and machining quality, and improve the performance of existing machine tools and effectively improve the manufacturing and manufacturing capabilities of enterprises. At the same time, it can save a lot of energy consumed in casting and cutting, and reduce the pollution to the environment.

The last century since 50s and 60s, especially since the reform and opening up, with the Chinese four construction, aerospace, ordnance, navigation, railways and other departments and large state-owned enterprises, the central enterprises from Europe and the United States, Russia, Japan and other industrialized countries spend high price purchases a large number of high-end, precision and automation of machining tool, and made great contribute to the improvement of the overall level of manufacturing technology in china.

But, like people, high-end machine tools will also age, control technology aging, control components aging, structural parts old aging. A lot of equipment is more old, long used, difficult to repair so old and old, lack of arms, legs, close or have been scrapped. To these high-end machine tools, the traditional solution, nothing more than the downgrade, overhaul, and scrap update.

First, the downgrade is used, which is often aimed at the imported equipment that is not too long and can continue to be used. Since it is demoted, the machining precision and efficiency has been difficult to meet the requirements, "tasteless gesture, and reluctant to update. For this kind of machine tool, if we use the "green remanufacturing" method to find out the problem, we can still restore the youth. In this way, the cost is not much, the workload is small, the effect is fast and the effect is good.

Besides the overhaul and renovation, the traditional overhaul is nothing more than the partial repair and restoration accuracy of the mechanical parts, the replacement of the components of the electric control hydraulic components, or the improvement of the structure in a small range, or the transformation of general equipment into special equipment. Due to the uneven technological strength of some enterprises, some imported machine tools are too old. This method can only be changed locally, and can not restore or improve the efficiency of the equipment as a whole.

As for the abandonment, of course, it is the final destination of any equipment. But from the "green manufacturing" point of view, these basic parts such as machine tool bed and table still can be used, and these large parts after long-term use, to eliminate internal stress more thoroughly, if the waste utilization, the "green manufacturing" approach, into a new machine effect better than the new machine, and to avoid the waste of resources.

Therefore, the "green remanufacture" of high end machine tools is a new road of transformation in line with Chinese characteristics.
