Contact with the machining industry for many years, encountered many customers consulted the same problem. Asked in the aluminum oxidation process, the accuracy of the mechanical parts have a certain impact? Whenever a customer mentions this issue, we will inform the customer in detail. Oxidation of aluminum materials does affect the accuracy of mechanical parts because oxidation is a chemical treatment that will modify the appearance of the aluminum material and increase the hardness of the mechanical parts. This is also chemical coating technology!
How to control the precision of the mechanical parts during the oxidation process of aluminum materials, if the accuracy of fine mechanical parts and parts thickness is required, the size of the machined parts can be increased or the negative tolerance dimension can be increased according to the exact size after the oxidation treatment to ensure the fine mechanical quality. The workpieces are oxidized to reach the process requirements on the drawings. In the processing of mechanical parts, not only the thickness and precision of the drawings, but also the precision of holes, steps, hole-to-edge size requests, etc. These are the same as the thickness request processing.
The oxidation of aluminum material has an effect on the precision of mechanical parts, but it can be controlled in the processing technology of mechanical parts, and it can guarantee and meet the technical requirements on the drawings of customers!
