In the machining industry for many years, encountered many customers consulting aluminum alloy processing technology related issues. In the oxidation process of aluminum alloy materials, does it have a definite impact on the accuracy of mechanical parts? Whenever the customer mentioned this problem, we will inform the customer in detail. The oxidation of aluminum alloy has an impact on the accuracy of mechanical parts, because oxidation is a chemical treatment, which can modify the appearance of aluminum and improve the hardness of mechanical parts. This is also chemical coating technology!
In the machining process, how to control the precision of mechanical parts in the process of aluminum oxidation treatment? If there is a precision request for the thickness and process size of fine mechanical parts, you can add the process size or negative deviation size of mechanical parts according to the accurate size after oxidation treatment, so as to ensure that the fine mechanical parts can meet the process request on the drawing after oxidation treatment. In the machining process of mechanical parts, not only the size and thickness of the drawing have accuracy, but also the size request of fine hole, step, hole to edge, etc. These are the same as the processing method of thickness request. The allowance should be changed according to the size in the processing.
