Custom Aluminum Machined Parts CNC Mechanical Parts Processing Milling CNC Parts
In a broader sense, CNC machining generates components with precise tolerances and impressive
material properties. It is well-suited for individual tasks and low-to-medium volume production
(up to 1,000 parts) due to its high repeatability. However, it does impose more design constraints
compared to 3D printing, primarily due to its subtractive nature.
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

Company Profile
FAQ's
1. What are the advantages of CNC machining?
The advantages of CNC machining are multifaceted, including rapid prototyping and the swift
production of full-scale parts. Notably, it excels in delivering high precision and accuracy in
manufacturing across various part sizes.
CNC machining enables tight tolerance machining for parts of all dimensions.
Furthermore, it provides unparalleled flexibility in terms of volume, pricing, lead times,
and the diverse range of materials and finishes utilized.
2. What size of fillets are added when no specific fillet is specified by the 3D model
or drawing?
In the absence of a specified fillet radius in the 3D model or drawing, the machinist will add fillet
radii based on discretion to facilitate easy machining. Should a specific fillet radius be required,
clear specification is essential.
As a general guideline, internal vertical edge radii might exceed 1/3 of the depth, while internal
horizontal edges may either be left sharp or feature a radius ranging from 0.5mm to 1mm.
