Although remanufacturing is no longer a fresh word, it is no doubt that its popularity has not diminished.

Remanufacture is the process of rejuvenating old machinery and equipment. It uses the old machinery and equipment as the core (Core), adopts a special process and technology, carries out a new manufacturing on the basis of the original manufacturing, and the remanufactured product is not inferior to the original new product in terms of performance or quality.

Scientifically speaking, remanufacturing is an industry that implements high-tech repair and transformation of used and end-of-life products. It is aimed at components that are damaged or are about to be scrapped. Based on the analysis of performance failure analysis and life assessment, the remanufacturing project is carried out. The design adopts a series of related advanced manufacturing technologies to make the quality of remanufactured products reach or exceed new products.

Remanufacturing is a physical process. For example, if an old engine is used, after some repairs and transformations, the final installation is still an engine, not anything else. From this perspective, remanufacturing differs from the recycling of waste materials.
Remanufacturing also has the characteristics of a chemical process. Although the old engine is still an engine after remanufacturing, its raw materials or components have been reborn, and the remanufactured product is not a “second-hand goods” but a brand-new product, so remanufacturing is not equal to the general circulation of raw materials. use.
The essence of remanufacturing is repair, but it is not simple maintenance. Remanufactured cores are manufactured using the manufacturing model, which is a high-tech repair technique, and it is an industrialized repair. Therefore, remanufacturing is an advanced stage of maintenance and development, and it is a kind of traditional maintenance concept. Promote and rewrite.

The practice at home and abroad shows that the performance and quality of remanufactured products can reach or even exceed the original product, but the cost is only 1/4 or even 1/3 of the new products, energy saving can reach more than 60%, and material saving can be more than 70%. Industry insiders believe that tapping the potential value of manufacturing products to the maximum extent and making energy resources close to “zero waste” is the greatest significance of developing the remanufacturing industry.

Machine tools take the road of sustainable development, and vigorously developing the remanufacturing of machine tools is a historical choice and has long been a trend.

As early as the early 1980s, the world-wide remanufacturing of machine tools was in a golden period of development. At that time, various countries saw the huge development prospects of machine tools, and they all developed the machine tool remanufacturing industry. At present, although the machine tool industry in developed countries such as the United States, Japan, and Germany is no longer brilliant, machine tool transformation has become a new growth point. The old machine tools generally have residual value of 45% to 80%, mainly due to the durability of the bed, columns, and bases. Remanufacturing these main parts requires the consumption of large amounts of steel and energy. If you retain the main body, repair or replace damaged parts, you can create equipment with the same quality and even better performance as the new equipment.

With the development of manufacturing, the amount of cutting tools is also rapidly increasing. In order to cope with the consumption of resources and the increase of raw material prices, reduce manufacturing costs and environmental pressure, some developed countries and enterprises have recycled and reused used cutting tools many years ago.

Remanufacturing has great significance and far-reaching influence on the machine tool industry. Today, as energy becomes increasingly tight and the climate and environment continue to deteriorate, low-carbon, environmental protection, and energy-saving and emission reduction have become topics of concern in the world. Countries all over the world are advocating low Carbon energy conservation, as an important part of the manufacturing industry, the machine tool industry must also take the re-manufacturing development path as a circular economy model of “resources-products-waste products-remanufacturing products”, and the social possession of machine tools worldwide is constantly increasing. With growth, the remanufacturing industry has great potential for development. Moreover, the development of the remanufacturing industry is also conducive to the formation of new economic growth points and provides the society with a large number of job opportunities.
