When processing high-precision aluminum alloy parts or large aluminum alloy parts, the surface smoothness of the product is very important. The appearance of a product can directly affect its cost-effectiveness. So, how to make some aluminum alloy parts with high surface smoothness achieve high luminous efficiency? Firstly, it is necessary to use cutting oil instead of cutting fluid for machine tools. The smoothness effect of five axis CNC Machining cutting fluid is not as good as that of cutting oil, but its cooling effect is stronger than that of cutting oil. If products need to achieve high gloss effect, cutting oil suitable for smooth cutting is mostly used.

Then when choosing cutting tools, we need to choose aluminum alloy high gloss knives specifically designed for aluminum alloy products. Tungsten steel knives and high gloss knives have different raw materials and hardness, so compared to tungsten steel knives, high gloss knives are more suitable for aluminum alloy smooth surfaces and cutting. When machining with a machine tool, it is necessary to align the oil pipe of the machine tool with the tool and push it down from top to bottom. This can first ensure that the tool has smooth cutting oil to assist in cutting, and then most of the aluminum slag and chips that are cut off can be washed away to reduce the probability of affecting the smoothness of the product due to slag squeezing. During machining, it is also important to remember to use an air gun to blow out the slag and chips that cannot be flushed out by the cutting oil. The feed speed during machine tool machining is necessary to give the appropriate parameters according to the length of the tool, and speed and feed are often important factors that determine the smoothness of the product.
