For aluminum products with different alloy compositions, there are many key points for the applicability and optimization of special cutting fluid for aluminum products.
First of all, aluminum products with different alloy compositions have different physical and chemical properties. For example, some aluminum alloys with high silicon content are prone to built-up edge during cutting, which requires the cutting fluid to have good lubrication properties to reduce the friction between the tool and the workpiece and prevent the generation of built-up edge. For aluminum alloys containing alloying elements such as copper, the hardness is relatively high, and the cutting fluid needs to have sufficient cooling capacity to reduce the temperature of the cutting zone and prevent the tool from overheating and wear.
In terms of applicability, the pH value of the cutting fluid is a key factor. For some aluminum alloys that are sensitive to alkalinity, a cutting fluid with a pH value close to neutral or acidic should be selected to avoid corrosion on the surface of aluminum products. For some aluminum alloys with good corrosion resistance, a cutting fluid with a certain alkalinity can be appropriately selected to enhance the cleaning performance of the cutting fluid.
When optimizing the selection, the additive composition of the cutting fluid should be considered. Cutting fluids containing extreme pressure additives such as sulfur and phosphorus may have better processing effects on some aluminum alloys, but they should be used with caution for some aluminum products used in aerospace and other applications that require extremely high surface quality, because these additives may affect the subsequent surface treatment and welding performance of aluminum products. At the same time, different processing techniques, such as roughing and finishing, also require cutting fluids with different performances. Roughing pays more attention to the cooling and chip removal capabilities of the cutting fluid, while finishing requires higher lubricity and surface quality improvement of the cutting fluid. In addition, the biological stability of the cutting fluid should also be considered to prevent it from deteriorating and stinking during use, affecting the processing environment and the quality of aluminum products.
In short, for aluminum products with different alloy compositions, it is necessary to comprehensively consider their characteristics, processing technology and other factors to select suitable and optimized Special cutting fluid for aluminum products to improve processing efficiency and product quality.
