Aluminum parts processing, a key aspect of metal fabrication, is widely used. Aluminum alloys, made by mixing pure aluminum with elements like copper and magnesium, are the base materials. These alloys, often in the form of aluminum sheet metal, are highly versatile.
For shaping aluminum parts, aluminum metal cutting is crucial. Methods such as sawing, milling, and laser cutting are applied to cut aluminum. Carbide – tipped tools are effective for this task. If you need to cut aluminum, you can find services for “aluminum cut” or “aluminum fabrication near me”. Besides cutting, forming operations like bending and rolling also play important roles. Quality control ensures the parts meet standards. In short, aluminum parts processing enables the creation of diverse components for various industries.

5-Axis CNC Machining Aluminum
If you want to get a machined aluminum part with high accuracy and complex geometries, 5-axis CNC machining may well fulfill your demands. The workpiece can be processed in multiple directions along with cutting in five angles of the axes simultaneously. Our advanced 5-axis CNC machines make it possible to complete all styles of aluminum milling tasks that require machined parts with extreme precision and complex shapes.
Efficiency
One single setup helps to save setup time, fasten the lead time, and increase productivity.
Intricate geometry
5-axis CNC machines with versatile configurations allow for the complex geometry of aluminum parts.
Higher accuracy & tolerance
Workpieces can be machined in a single run, thus quality is improved while error is reduced.
Higher spindle speeds and feed rates
The load on the cutting tool can be reduced by the use of more rigid and shorter tools.
aluminum fabricators
In CNC machining, the dimensional stability of aluminum is very important. Stable dimensions can ensure that parts fit tightly, guarantee the overall performance and quality of the product, reduce scrap rate, and reduce material waste and cost.
Mitigate inherent stresses within the material
During the manufacturing process, different kind of aluminum has their own internal stresses in the material. Two methods widely used to eliminate inherent stresses respectively are vibration treatment and natural or artificial aging. Another common way is that cut the excess parts ahead of 1-2 hours of natural aging and then move to process.
Choose the right fixture for the workpiece
These methods below can help the thin-walled aluminum parts with poor rigidity to improve the precision in the CNC machining process:
- Use a vacuum table for large sheet material
- Choose a pneumatic or mechanical vise for smaller or odd-shaped parts
- Fill a medium into the interior of the workpiece
- Use suction cups to make clamping force well distributed along with the thin plate
Determine the exact cutting tool
A longer tool may cause the tool deflection on your finished parts. So the shorter tool always is the first choice in CNC aluminum machining. Choosing the correct material and geometric parameters of the tool makes a difference in reducing cutting forces and allowing for excellent chip evacuation.
Choose a suitable machining process
The aluminum CNC machining processes generally take four steps: rough machining – semi-finish machining – clear corner machining – finishing.
When it comes to high accuracy, it can be taken into consideration that the number of semi-finishing operations should be increased and a uniform machining allowance should be sustained.
Determine the feeds and speeds
- Select the appropriate feed, spindle speed rates, and depth of cut
- Process the front and rear of the workpiece symmetrically
- Machine all cavities of the workpiece with multi-layer
- Drilling should come before milling when machining parts feature cavities
Aluminum Material Grades Available with Us
Aluminum alloys possess diverse characteristics, including malleability, weld – ability, a high strength – to – weight ratio, corrosion resistance, light weight, electrical conductivity, and superb anodized surface treatment. Owing to its affordability and ease of shaping, aluminum is extensively utilized in industrial sectors. The specific aluminum grade you select is determined by the intended application of your aluminum components in the manufacturing endeavor.
Aluminum 6061
Aluminum 6061 (CNC) is mostly used as the standard grade for CNC machining. This alloy is widely applied in aerospace for components like brackets, in automotive for frames, and in general machinery, making it a go – to choice in various engineering fields.
Aluminum 6082
Aluminum 6082 (CNC) is a type of aluminum with higher strength than all of the 6000 series alloys and superb corrosion resistance. It can be a substitute for 6061 in many applications. In the transportation industry, it’s used for truck and train parts.
Aluminum 6063
Aluminum 6063 is known as an extrusion alloy as well as an architectural alloy. So it is widely found in various interior and exterior architectural applications, and aluminum extrusion applications. It has a medium strength so it may not be suited for applications that need high strength.
Aluminum 7075
Aluminum 7075 is one of the highest strength aluminum alloys available. It has an excellent strength-to-weight ratio, and it is ideally used for highly stressed parts. 7075 aluminum is a typical material used in the aviation industry with complex structure and high precision.

Finishing Choices in Aluminum CNC Machining
After machining an aluminum part, there commonly leaves the roughness on the surface. To meet your specific requirements, we provide various options for post-machining processes to enhance the physical, mechanical, and aesthetic features of the part. The main processes we offer:
Baking paint
The aluminum part is applied, and the coated object is placed in an oven. The heat in the oven cures the paint, forming a hard, durable finish. This process enhances the paint’s adhesion and resistance to scratches, chemicals, and fading. Baking paint is widely used in automotive.
The electrochemical anodizing, aluminum is put in an acid electrolyte bath. Applying voltage across the cathode and anode forms a corrosion – resistant, non conductive aluminum oxide coating on the surface. This process can also enhance the look and add color.
Powder coat
The aluminum part is powder coated using an electrostatic spray gun. The charged powder is sprayed onto the part. Overspray can be recycled. Powder coating is an excellent finishing approach. It combines aesthetics, durability, and sustainability while enhancing the part’s mechanical properties.
Heat Treatment
Heat treatment is employed to increase the strength and hardness of a specific subset of aluminum alloys, that is the precipitation-hardenable wrought and cast alloys. The mechanical properties of aluminum parts will perform better after heat treatment.
