In the manufacturing industry, cutting fluid is crucial for CNC machining, precision parts machining, and medical parts machining. It can not only reduce cutting temperature and tool wear, but also improve machining accuracy and surface quality. However, with increasingly stringent environmental regulations, there are some contradictions between the use of cutting fluid and environmental regulations.
Analysis of contradictions
- Pollution emission issues: In the process of CNC machining and mold machining, a large amount of waste liquid will be generated after the cutting fluid is used. These waste liquids often contain harmful substances, such as heavy metals, mineral oils, chemical additives, etc. If they are directly discharged without effective treatment, they will cause serious pollution to the soil and water bodies. For example, some small processing plants discharge cutting fluid waste liquid at will to save costs, causing pollution to surrounding water sources, affecting the ecological balance and residents' health.
- Ingredient restriction problem: Environmental regulations have imposed strict restrictions on certain ingredients in cutting fluids. Additives such as chlorine and sulfur can improve the performance of cutting fluids, but they will produce harmful gases during the processing process and pollute the atmospheric environment. In precision machining, the use of cutting fluids containing such ingredients may face compliance risks.
Methods to resolve contradictions
- Technological innovation: The development of environmentally friendly cutting fluids is the key. New cutting fluids use biodegradable base oils and additives to reduce harm to the environment. For example, water-based synthetic cutting fluids use water as the main component and add a small amount of environmentally friendly additives. They not only have good cooling and lubrication properties, but are also easy to handle and meet environmental protection requirements. At the same time, improve the cutting process and use dry cutting or micro-lubrication technology to reduce the amount of cutting fluid used. In five-axis CNC machining, micro-lubrication technology sprays a very small amount of lubricant into the cutting area, which can not only meet the processing needs, but also reduce the pollution caused by cutting fluids.
- Optimize management measures: Establish a complete cutting fluid management system to monitor the procurement, storage, use and waste treatment of cutting fluids throughout the process. Enterprises must strictly follow the requirements of environmental protection laws and regulations, select compliant cutting fluid products, and regularly test and maintain cutting fluids to extend their service life. For the waste fluids generated, entrust professional environmental protection treatment companies to handle them to ensure that they meet the emission standards. In medical parts processing companies, standardized management can ensure that the production process meets environmental protection requirements and guarantees product quality.
- Strengthen employee training: Improve employees' environmental awareness and operating skills. Let employees understand the requirements of environmental protection laws and regulations and the correct use and treatment of cutting fluids to avoid environmental pollution caused by improper operation. For example, train employees on how to correctly add and replace cutting fluids to prevent waste fluid leakage.
The contradiction between cutting fluid use and environmental protection laws and regulations is not irreconcilable. Through technological innovation, optimized management and strengthened employee training, it is possible to achieve environmental protection goals while meeting processing needs and promote the sustainable development of the manufacturing industry. In the fields of CNC machining, precision parts machining, medical parts machining, etc., resolving this contradiction will lay a solid foundation for the green development of the industry.
