With the increasing global emphasis on environmental protection, green manufacturing has become a new trend in the development of the machine tool industry. At the exhibition, energy-saving, emission reduction and recyclable green machine tool products and technologies were unveiled. New machine tools are designed with energy-saving drive systems, optimized structures to reduce material consumption, and at the same time reduce the use of cutting fluids and other consumables by improving the machining process to reduce pollution of the environment. Some companies also showed the machine tool remanufacturing technology, through the repair and upgrading of used machine tools, so that their performance meets or even exceeds the new product, to achieve the recycling of resources, to practice the concept of sustainable development.
