In the process of processing aluminum alloy, the use of cutting fluid is essential, but there are many types of cutting fluid, and different types have different effects on the use of cutting fluid. Therefore, cutting fluid should not be used indiscriminately. We all know that synthetic cutting fluids are widely used, so why can't synthetic cutting fluids process aluminum alloys? Today, let me share with you what the secret is!
One reason why synthetic cutting fluids cannot process aluminum alloys is that oxidation and blackening are prone to occur during the processing of aluminum alloys, and the chemical composition contained in synthetic cutting fluids cannot effectively avoid this situation. Therefore, synthetic cutting fluids are not suitable for use in aluminum alloy processing. The second reason why synthetic cutting fluid cannot process aluminum alloys: Synthetic cutting fluid has relatively poor lubrication and rust resistance during the processing of aluminum alloys. Therefore, aluminum alloys are prone to deformation during processing, which affects the processing quality of the workpiece. Oxidation and rust are also an important and troublesome influencing factor. The third reason why synthetic cutting fluids cannot process aluminum alloys is that aluminum and aluminum alloy materials are soft and have high viscosity. Therefore, it is necessary to choose cutting fluids with good cooling and permeability during the processing process, in order to effectively cool down during the processing and maintain good shape and quality of aluminum alloy workpieces. The fourth reason why synthetic cutting fluid cannot process aluminum alloys is that the pH value of the cutting fluid used for aluminum alloy processing is relatively high, usually between 8.0 and 8.5. If the pH value is too high, the corrosion will be stronger, which will have a negative impact on the processed aluminum alloy workpiece. Therefore, it is required to use professional cutting fluids during the processing of aluminum alloys.
When using cutting fluids, we must have a better understanding of the materials used and the performance and characteristics of the cutting fluid, in order to help us better process and improve the quality and efficiency of the workpiece.
