Against the backdrop of global climate change and resource shortages, green manufacturing has become an inevitable trend in the development of the manufacturing industry. As an important part of the manufacturing industry, the machining industry is actively responding to the country’s “dual carbon” goals, accelerating energy conservation and emission reduction through technological innovation and process optimization, and contributing to the realization of sustainable development.
Challenges faced by the machining industry
The traditional machining industry has many environmental problems in the production process:
·High energy consumption: CNC machine tools, cutting equipment, etc. consume a lot of electricity.
· High pollution: The use of chemicals such as cutting fluids and lubricants pollutes the environment.
· Resource waste: Low material utilization and large amount of waste generated.
These problems not only increase the operating costs of enterprises, but also have a negative impact on the ecological environment. Therefore, promoting green manufacturing has become an urgent need for the machining industry.
New Trends in Green Manufacturing
In recent years, the machining industry has made significant progress in energy conservation and emission reduction, which is mainly reflected in the following aspects:
1.Application of high-efficiency energy-saving equipment
New CNC machine tools and processing equipment use energy-saving motors and intelligent control systems, which can automatically adjust power output according to processing needs and significantly reduce energy consumption. For example, some companies have begun to use energy recovery systems to convert heat energy generated during equipment operation into electrical energy to achieve energy recycling.
2.Dry cutting and micro-lubrication technology
The use of traditional cutting fluids is not only costly, but also pollutes the environment. Dry cutting and micro-lubrication technology reduces environmental pollution and improves processing efficiency by reducing or completely avoiding the use of cutting fluids.
3.Promotion of green materials
The machining industry is gradually promoting the use of recyclable materials and environmentally friendly cutting fluids. For example, biodegradable cutting fluids are used instead of traditional mineral oils to reduce pollution to soil and water sources.
4.Intelligent and digital management
By introducing intelligent manufacturing and industrial Internet technologies, companies can monitor equipment operating status and energy consumption data in real time, optimize production processes, and reduce resource waste. For example, big data analysis can be used to predict equipment maintenance time and avoid energy waste caused by equipment failure.
5.Waste recycling and reuse
Metal waste and cutting chips generated during machining can be recycled and reused to make new raw materials, reducing resource waste. Some companies have also established a closed-loop production system to directly use waste materials in the manufacture of new products.
Future Outlook
Green manufacturing is not only the development trend of the machining industry, but also an important way for enterprises to enhance their competitiveness. In the future, with the continuous advancement of technology and the continuous support of policies, the machining industry will make more breakthroughs in energy conservation and emission reduction:
· Application of clean energy: Clean energy such as solar energy and wind energy will gradually replace traditional energy.
· Promotion of circular economy: More enterprises will establish closed-loop production systems to achieve efficient use of resources.
· Improvement of green standards: The industry will formulate stricter green manufacturing standards to promote the transformation of enterprises to sustainable development.
Conclusion
Green manufacturing is the only way for the machining industry to achieve high-quality development. Through technological innovation and process optimization, the machining industry is accelerating the promotion of energy conservation and emission reduction, contributing to the protection of the ecological environment and the realization of sustainable development.
