How to control the accuracy of materials Aluminum alloy Oxidation Anodized with surface treatment ?

- Dec 11, 2019-

In the precision CNC machining industry, many customers have encountered the same problems. Asked whether there is a definite influence on the accuracy of mechanical parts during the aluminum oxidation process ?

The oxidation of Aluminum alloy materials (Such as: Alu 6061; 6082; 7075) does have an impact on the accuracy of mechanical parts, because oxidation is a chemical treatment method that will modify the appearance of aluminum materials and increase the hardness of CNC mechanical parts.


This is also chemical coating surface technology !


How to control the precision of CNC mechanical parts during the oxidation process of aluminum ?

If the precision of the thickness of the mechanical parts is required, the process size or negative difference size of the machined parts can be increased according to the accurate size after oxidation treatment to ensure the fine machinery. 


The processed part meets the process requirements on the drawing after oxidation treatment. 

In the process of machining mechanical parts, not only the size and thickness of the drawings are accurate, but also the size requirements of fine holes, steps, holes to edges, etc. 

These are the same as the thickness request processing method.


The oxidation of aluminum material has an impact on the accuracy of CNC mechanical parts, but it can be controlled in the CNC machining process of mechanical parts, 

which can ensure and meet the process requirements on the customer's drawings !
