Custom processing aluminum alloy parts precision CNC machine turning aluminum anodized black non-standard accessories

Aluminum alloy hard anodizing:

Aluminum alloy parts' hard anodizing usually also becomes hard oxidation, which is a kind of anodizing with higher requirements for the wear resistance of the workpiece oxide film, generally can be divided into: 

(1) Sulfuric acid hard anodizing method;

(2) Oxalic acid hard anodizing method;

(3) Mixed acid hard anodizing; if not specified, it generally refers to sulfuric acid hard anodizing.

Material: Aluminum and aluminum alloys, the common ones are: 2A12, 5052, 6061, 6063, 7075, etc.; in addition, cast aluminum alloys, such as ADC10, ADC12, A356, A380, etc., are often hard anodized; For deformed aluminum alloys with copper content greater than 5% or silicon content greater than 8%, or high silicon pressure casting aluminum alloys, when doing hard anodizing, some special measures for anodizing need to be added, for example: for 2XXX series aluminum alloys, to avoid the aluminum alloy being burned during the anodizing process, 385g/L sulfuric acid plus 15g/L oxalic acid can be used as the electrolytic bath solution, and the current density should also be The current density should be increased to more than 2.5A/dm.

Custom machining aluminum alloy parts precision CNC machine tool turning aluminum anodizing black non-standard accessories, aluminum alloy machining features:

1, aluminum alloy strength, hardness is lower than copper, cutting machinability better;

2. aluminum turning body processing is easy to stick to the tool, forming a tool tumor, and processing surface roughness becomes large;

3. aluminum alloy organization is not dense enough, so it is difficult to obtain a smaller roughness;

4. tool life is generally higher;

5. the aluminum alloy body is easy to cause deformation when mounting and machining and the surface of the workpiece is also easy to bruise or scratched;

6. The expansion coefficient of aluminum alloy is greater, which affects the dimensional accuracy more prominently.
