Aluminum CNC Machining by Grade

We provide a variety of processing services for various aluminum alloys, including CNC machining, die casting, aluminum extrusion, sheet metal processing, 3D printing, etc. Each aluminum alloy is suitable for different applications according to its characteristics. VMT has more than 15 years of experience in CNC aluminum machining services. We are your best partner to improve your market benefits. The following are the aluminum materials we often CNC machining:

Aluminum 6061 CNC Machining

Choose 6061 when your project needs dependable strength and a high-quality anodized finish without the cost of a specialty alloy, such as equipment housings or mounting brackets. Its stable machining performance helps maintain tight tolerances across production runs, while its consistent anodizing response delivers a more uniform appearance for visible components.

Explore 6061 CNC Machining Service

Aluminum 7075 CNC Machining

Choose 7075 when your project needs maximum strength-to-weight ratio, such as structural brackets or robotics components that must withstand high stress without adding bulk. Its high hardness supports tight tolerances and clean edges, though it takes more careful process control than general-purpose grades like 6061.

Explore 7075 CNC Machining Service

Aluminum 2024 CNC Machining

Choose 2024 when your project needs high fatigue resistance under repeated stress, such as drone frames or structural components subject to cyclic loading. It offers an excellent strength-to-weight ratio, with superior fatigue performance compared with many general-purpose aluminum grades, though it requires additional corrosion protection such as anodizing or Alclad cladding in exposed environments.

Explore 2024 CNC Machining Service

Aluminum 6063 CNC Machining

Choose 6063 when your project needs excellent surface finish and clean edges after anodizing, such as trim components or decorative enclosures. Its lower strength compared to 6061 is offset by superior extrudability and a smoother finish, making it a practical choice for appearance-focused parts that don’t carry heavy structural loads.

Aluminum CNC Machining by Capability

VMT performs precision cnc aluminum machining across milling, turning, 5-axis, and Swiss processes, handling complex geometries and tight tolerances with the right method for each part.

Aluminum CNC Milling Part

Flat faces, pockets, slots, and complex 3D contours all fall under milling. VMT’s aluminum cnc milling service uses 3-axis, 4-axis, and 5-axis machines to cut setup time and hold tight tolerances on multi-feature parts.

Aluminum CNC Turning Part

If your part is round, such as a shaft, bushing, or threaded fitting, turning is the right process. Our aluminum cnc turning parts capability includes live tooling, so milled features can be added without a second setup.

Aluminum Mill-Turn Part

Parts that combine round and non-round features in one component are where mill-turn earns its keep. Completing both operations in a single setup keeps concentricity tight and avoids the tolerance drift that comes with switching machines.

Get a Quote

Aluminum 5-Axis Machining Part

Angled faces and features on multiple sides usually mean multiple setups, unless you have 5-axis capability. Machining multiple sides in a single setup avoids repositioning errors, keeping your part accurate without extra fixtures.

Aluminum Swiss Machining Part

Small-diameter, long, or slender parts tend to deflect under standard turning. Swiss machining holds tight tolerances on precision pins, shafts, and connector components that would otherwise drift out of spec.

Thin-Wall Aluminum Machining Part

Housings and enclosures with thin walls are prone to vibration and warping during cutting. Our fixturing and process control keep wall thickness consistent, so your part holds its final dimensions.

Advantages of CNC Machining Aluminum Parts

CNC machining is one of the most efficient and reliable ways to produce aluminum parts. Here are the key advantages of using CNC machining for aluminum parts:

1. Lightweight Yet Strong
Aluminum is much lighter than steel but still strong enough for many industrial uses. This makes it ideal for parts where weight reduction is important, such as in automotive or aerospace components.

2. Excellent Machinability
Aluminum is easy to cut, drill, and shape, which makes the CNC machining process faster and more cost-effective. It allows for high-speed machining with less tool wear.

3. High Precision and Accuracy
CNC machines can achieve tight tolerances when machining aluminum. This means each part can be made with consistent size, shape, and quality, especially important for complex or technical designs.

4. Good Corrosion Resistance
Aluminum naturally resists rust and corrosion. This makes it suitable for outdoor or harsh environments without needing extra coatings or treatments.

5. Attractive Surface Finish
Aluminum parts can be easily finished with polishing, anodizing, or painting to improve their appearance and durability. It’s ideal for both functional and aesthetic applications.
