Traditional mechanical processing methods often emit a large amount of waste and waste water in the production process, causing serious pollution to the environment. However, in recent years, with the gradual improvement of my country’s social development level and the increasing awareness of social environmental protection, mechanical processing methods It is also developing in a more environmentally friendly and green direction. The overall trend of world industrial development is towards green processing, and the concept of green production will also highlight its advantages with the development of higher quality of the economy. The development of mankind must not only take into account the development efficiency but also the living environment. Therefore, the application of environmental protection technology is a top priority for machinery processing enterprises. The application of environmental protection technology in mechanical processing has far-reaching significance. On the one hand, it can promote the mechanical processing industry to accelerate the pace of industrial transformation, and on the other hand, it can achieve the purpose of resource conservation and environmental protection.
