The processing of aluminum products involves a variety of processes, such as turning, milling, drilling, etc. In order to improve processing efficiency, extend tool life and ensure workpiece quality, it is crucial to correctly select and adjust the concentration of special cutting fluid for aluminum products. The following will introduce how to adjust the concentration of cutting fluid according to different processing needs to achieve the best effect.
1. Understand the role of cutting fluid
Cutting fluid mainly plays the role of cooling, lubrication, cleaning and corrosion protection. The cooling function helps to take away heat and prevent the tool from being damaged by high temperature; lubrication reduces the friction between the tool and the workpiece; the cleaning function helps to remove chips and dirt; and the anti-corrosion function protects the surface of the workpiece from chemical reactions.
2. Consider the type of processing
Different types of processing have different requirements for cutting fluid. For example, in rough processing, stronger cooling performance is usually required, so the proportion of water can be appropriately increased; in fine processing, more attention is paid to lubrication, and the proportion of oil-based components should be increased at this time.
3. Basic principles for adjusting concentration
Generally speaking, the concentration range of cutting fluid is between 3% and 10%, depending on the processing conditions. Lower concentration cutting fluids (about 3%-5%) are suitable for roughing because they provide better cooling effect; while higher concentration cutting fluids (about 5%-10%) are more suitable for finishing because they provide better lubrication effect.
4. Use a concentration meter for measurement
To accurately adjust the concentration of the cutting fluid, it is recommended to use a concentration meter (such as a refractometer). By measuring regularly, you can ensure that the concentration of the cutting fluid is within the ideal range and avoid the adverse consequences caused by too high or too low.
5. Pay attention to maintenance and replenishment
During the processing process, the concentration of the cutting fluid will gradually change due to evaporation, contamination, etc. Therefore, it is necessary to monitor regularly and replenish fresh cutting fluid or water in time to maintain the required concentration level.
6. Consider environmental factors
Changes in ambient temperature will also affect the performance of the cutting fluid. In seasons with higher temperatures, the concentration may need to be appropriately reduced to improve the cooling effect; on the contrary, in cold conditions, the concentration may need to be increased to enhance the lubrication effect.
7. Adjust according to tool material
Different tool materials (such as high-speed steel, carbide, etc.) have different requirements for cutting fluid. Generally speaking, carbide tools can withstand high concentrations of cutting fluid better than high-speed steel tools, so the concentration can be adjusted according to the specific tool type.
8. Comprehensive consideration of cost-effectiveness
Finally, cost-effectiveness needs to be considered comprehensively. Although increasing the concentration of cutting fluid may bring better processing results, it will also increase costs. Therefore, it is very important to find the best balance between cost and effect while meeting the processing needs.
Through the above methods, the concentration of Special cutting fluid for aluminum products can be effectively adjusted, thereby optimizing the processing process and improving production efficiency and product quality.
