Custom CNC Aluminum Parts CNC Milling Parts Machining Services CNC Parts Suppliers
The CNC machining process, standing for computer numerical control machining, is a subtractive
manufacturing approach that utilizes a synergy of computerized controls and machine tools to
eliminate layers from a solid block of material.
Programming dictates the desired cuts in the metal, aligning them with specific tools and machinery,
and the automated process executes the machining task accordingly.
Product Details
Aluminum is an excellent material for CNC machining due to its high
machinability, ductility,
and favorable strength-to-weight ratio. It offers outstanding thermal and electrical conductivity,
low density, and inherent resistance to corrosion.
| Common Aluminum Materials | |
| Name | Properties |
| Aluminum 2011 | High mechanical strength alloy, weldability, strength, and anodizing response are all rated as average at best. Typically used in the manufacture of machine parts, screw machine products, tube fittings, pipe stems, hoses and atomizer parts. |
| Aluminum 4032 | Offers superior service in both low and high-temperature service. Typically used in the manufacture of electric vehicle battery and motorsport applications include battery terminals, racing pistons, engines components and chassis components. |
| Aluminum 6061 | Good mechanical properties and weldability, making it one of the most common alloys for general use. Typically used in the manufacturing of aircraft, electric vehicles parts and bicycle components. |
| Aluminum 7075 | Good fatigue strength but is not weldable and has limited resistance to corrosion. It often used in transport applications including marine, automotive and aviation. Typically used in the manufacturing of aircraft fitting, gears and shaft, regulating valve parts. |
Aluminum Finishing and Post-Processing
Aluminum can also be anodized for additional surface protection and aesthetic finishes.
| Name | Machining Marks |
| Anodizing Type II | Reduced for non-cosmetic, removed on primary surfaces for cosmetic |
| Anodizing Type III | Visible under anodizing |
| Chromate conversion coating | Visible |
| Electroless nickel plating | Reduced but visible |
| As machined | Visible, light surface scratches |
| Smooth machining | Visible, light surface scratches |
| Fine machining | Slightly visible |
| Polishing | Removed on primary surfaces |
| Bead blasting | Removed for non-cosmetic, removed on primary surfaces for cosmetic |
| Brushing | Reduced for non-cosmetic, removed on primary surfaces for cosmetic |
| Powder coating | Removed |

FAQ's
1. Machining Parameters Determined by Operators:
Most machining parameters are established by the machine operator during the generation of
G-code.Build Size of CNC Machines:
CNC machines offer a notably large build area, especially when
compared to 3D printers.
CNC milling systems can handle parts with dimensions up to 2,000 x
800 x 100 mm (78” x 32” x 40”).
CNC turning systems can machine parts with a diameter of up to Ø
500 mm (Ø 20’’).
Accuracy and Tolerances:
CNC machining enables the production of parts with high accuracy
and tight tolerances.
Tolerances achievable with CNC machines can be less than half the
diameter of an average human
hair, reaching ± 0.025 mm or .001’’.
If tolerance is not specified in the technical drawing, the
operator typically machines the part with
an accuracy of 0.125 mm (.005’’).
Key Takeaways:
CNC machines excel in both build size and precision, making them suitable for a wide range of
applications.
Operators have the flexibility to set machining parameters based on
the specific requirements of
the project.
Understanding the build size and achievable tolerances is crucial
for designing parts that meet
precision and accuracy standards.
2. How much do CNC machining materials cost?
CNC machining offers a plethora of material choices, leading to varying costs across different options.
The price range for materials is broad, influenced by factors such as physical properties and specific
characteristics of each material.
For metal parts, Aluminum 6061 stands out as the most economical choice.
If cost is a primary consideration, ABS emerges as the most budget-friendly option.
Additionally, the ease of machining significantly impacts costs, with materials like stainless steel
posing a higher machining difficulty compared to aluminum, thereby contributing to an increased
overall cost.
3. How quickly can I get my parts?
We can produce quality parts in as little as two weeks if complete 2D and 3D CAD models are provided.
However, more intricate parts with special features may require additional time.
For more precise lead times based on your project, request a quote.
Regarding shipping, the majority of our shipments are via air freight, taking only a few days from
China to Europe or North America.
