Micro nano bubble technology has a series of unique physical and chemical properties, which make it demonstrate potential application value in liquid treatment. For example, micro nano bubbles have a large specific surface area, a slow rise rate, the ability to dissolve under pressure, surface charge, and the ability to generate a large number of free radicals upon rupture. These characteristics make micro nano bubble technology have broad application prospects in multiple fields.

The role of micro nano bubbles in machine tool cutting fluid is mainly reflected in the following aspects:

1. Improving cooling performance: Micro nano bubbles have a large specific surface area and excellent thermal conductivity. When the cutting fluid flows through the cutting area, micro nano bubbles can quickly absorb and disperse the heat generated by cutting, effectively reducing the cutting temperature and preventing damage to the tool and workpiece due to overheating.

2. Enhanced lubrication effect: Micro nano bubbles can form a lubricating film in the cutting fluid, reducing friction and wear between the tool and the workpiece. This lubrication effect helps to extend the service life of cutting tools, improve machining accuracy and surface quality.

3. Optimization of cleaning effect: Micro nano bubbles can carry small particles and impurities generated during the cutting process, helping to remove them from the cutting area and maintain the cleanliness of the cutting fluid. This helps to reduce tool and workpiece blockage and wear, and improve machining efficiency.

4. Environmental protection and energy conservation: Micro nano bubble technology helps to reduce the use of cutting fluid, reduce the frequency of cutting fluid replacement, and thus reduce the impact on the environment. At the same time, micro nano bubbles can improve the cooling and lubrication performance of cutting fluid, and also help reduce the energy consumption of machine tools.

5. Prevention of cutting fluid odor: The surface charged characteristics of micro nano bubbles may help attract and kill bacteria in the cutting fluid, reduce bacterial growth, and micro nano bubble technology can prevent cutting fluid odor.

Improving the stability of cutting fluid: The small size and slow rising speed of micro and nano bubbles may help to distribute materials more evenly in the cutting fluid, reduce material precipitation and stratification, and thus improve the stability of the cutting fluid.

6. Improve the solubility of cutting fluid: The pressurized dissolution characteristics of micro nano bubbles can enhance the solubility and dispersion of various components in the cutting fluid, helping to maintain the cleanliness and effectiveness of the cutting fluid.

7. Reduce chemical reactions in cutting fluid: Micro nano bubbles can generate a large number of free radicals, which may participate in and neutralize certain chemical reactions in the cutting fluid, reduce the generation of harmful substances, and thus delay the odor of the cutting fluid.

Micro nano bubbles play multiple roles in improving cooling performance, enhancing lubrication, optimizing cleaning, and promoting environmental protection and energy conservation in machine tool cutting fluids. These effects collectively enhance the machining efficiency and product quality of machine tool cutting, providing strong support for the development of modern manufacturing industry.
