How do I do surface treatment for CNC aluminum parts processing?
The surface of the aluminium must be appropriately pre-treated before use.
Phosphating or a chromate coat might be used for the pretreatment of the components. The material is more corrosion-resistant as a result. After that, the aluminium is coated with dry powder using an electrostatic spray cannon, and it is cured at a high temperature.
The application of powder coating allows for a plethora of colour options to be selected. A thick coating can also be achieved by applying many coatings in successive layers. The coat might have a thickness of anything between 18 and 72 micrometres.

What is the use of cleaning oil stains on the surface of aluminum CNC machined parts?
In most applications, aluminium is seldom used in its purest form. Aluminium is a reactive metal that will happily corrode in an uncontrolled manner if some sort of protection is not applied to it first. Consequently, aluminium is typically either:
- Either an anodizing process that provides wear resistance, a more strong corrosion resistance, and an improved look or a conversion coating that provides limited corrosion protection and makes it easier for paint and adhesives to adhere to the metal.
- If there is oil all over the component, the conversion coating and anodizing baths won’t be able to react with the aluminium properly.
Aluminum machined parts and turning parts have high strength, good plasticity, excellent electrical conductivity
Tool Factors to keep in mind for CNC Machining Aluminum
You should pay attention to the following things when CNC cutting aluminium:
- The criteria for selecting the right tool will change depending on the part’s size and shape.
- The criterion for selecting the right tool will be influenced by the material.
- Your choosing procedure should take into account the kind of surface finish required by your application.
- Your selection procedure should take into account the surface finish required by your application.
- Which tools you should employ can also depend on the type of cutting being done.
- Which tools you should employ can also depend on the type of cutting being done.

Which aluminum is best for CNC machining?
Aluminium is a sturdy, conductive, and corrosion-resistant material; if a product team decides to produce a part out of aluminium, they may be confident that they have made the right choice. The aluminium alloys 2024-T4, 7075-T6, and 6082 perform the best in high-performance applications. However, the aluminium alloys 6061 and MIC 6 are suitable for usage in the majority of situations in which an all-purpose aluminium will do.
As CNC machining can perform such a wide variety of operations, it can be difficult for engineers to select the materials that would yield the best results for a certain project.
Cnc milling aluminum part and turned parts are required to be made with higher quality to avoid any unpleasant failure
What are the most common aluminum CNC machining processes?
- Manufacturers employ CNC metal lathes, also known as CNC metal turning centres, to remove material in a variety of industries with extreme precision.
- Compressed air is heated to a very high temperature by CNC plasma cutters to create a “plasma arc” that can melt metal up to six inches thick. Manufacturers utilise plasma cutters in a variety of industries because they are quick, accurate, relatively simple to use, and reasonably priced.
- To produce a cut edge, CNC laser machines either melt, burn, or vaporise the material.
- CNC water cutters slash through the material by forcing incredibly high-pressure water jets via a small nozzle.
