Aluminum Stainless Steel Anodized 3/4/5-axis Machining Services Cnc Milling Custom Part

Product Description  

Our Aluminum Stainless Steel Anodized 3/4/5 Axis Machining Services deliver custom CNC milled parts with unmatched precision and surface finish, specializing in aluminum and stainless steel materials with optional anodizing. Leveraging 3 - axis to 5 - axis machining centers, we can produce everything from simple prismatic components to highly complex 3D geometries, ensuring tight tolerances and repeatable quality for both prototypes and production runs.  

Aluminum parts benefit from our in - house anodizing capabilities, offering enhanced corrosion resistance, electrical insulation, and aesthetic appeal in various colors (clear, black, red, etc.). Stainless steel components are precision - milled to exploit their high strength and biocompatibility, with post - processing options like passivation or electropolishing available. The 5 - axis technology allows simultaneous machining of multiple surfaces in a single 

setup, reducing setup times and improving geometric accuracy for parts with deep cavities, inclined planes, or freeform surfaces.  

Features  

1. Multi - Axis Versatility:

  3 - Axis: Ideal for flat surfaces, slots, and 2.5D features, providing cost - effective solutions for straightforward parts.  

  4 - Axis: Adds rotational capability around a single axis, enabling efficient machining of cylindrical or indexed features.  

  5 - Axis: Offers full 3D freedom, allowing complex contours, undercuts, and multi - angle surfaces to be machined in one operation, minimizing tool path restrictions and maximizing material removal rates.  

2. Surface Treatment Expertise: Our anodizing process for aluminum meets MIL - A - 8625 standards, available in Type II (decorative) and Type III (hard coat) finishes. For stainless steel, we provide passivation to enhance corrosion resistance or electropolishing for smooth, mirror - like surfaces.  

3. Design Flexibility: Whether your project requires thin - walled structures (as thin as 0.5mm), deep pockets (depth - to - diameter ratio up to 10:1), or intricate lattice structures, our engineers use advanced CAM software to develop optimized tool paths that balance precision and efficiency.  

4. Material Performance: Aluminum parts offer a strength - to - weight ratio perfect for aerospace and automotive applications, while stainless steel components excel in high - corrosion environments like marine equipment or medical implants.  

Application

Aerospace Components: 5 - axis milled aluminum wing ribs and stainless steel turbine brackets, anodized for fuel resistance and wear protection.  

Medical Instruments: Custom stainless steel surgical implants with electropolished surfaces for biocompatibility, and aluminum endoscopic components anodized for easy sterilization.  

Industrial Automation: High - strength stainless steel gears and aluminum robotic arms, anodized in safety - yellow for visibility, used in assembly lines and CNC machinery.  

Consumer Electronics: Thin - walled aluminum smartphone casings with anodized color coatings, and stainless steel watch backs with precision - milled engravings.  

FAQ  

Q: What is the difference between your 4 - axis and 5 - axis services?  

A: 4 - axis machining adds a single rotational axis (usually the A - axis), while 5 - axis includes two rotational axes (A and B or A and C), allowing the tool to approach the part from any angle. 5 - axis is necessary for complex curves and undercuts, though 4 - axis is more cost - effective for simpler rotational features.  

Q: How long does the anodizing process take?  

A: Anodizing is typically completed within 24 - 48 hours after machining, depending on the finish type and part size. We can expedite this for rush orders upon request.  

Q: Can you machine parts with tight internal angles?  

A: Yes, our 5 - axis machines use long - reach, small - diameter tools to access tight corners, achieving radii as small as 0.2mm. For acute angles, wire EDM can be used as a secondary process if needed.  

Q: What is your standard tolerance for 5 - axis milling?  

A: Our standard tolerance is ±0.02mm for most features, with tighter tolerances (±0.01mm) available upon request for critical dimensions. All tolerances are clearly defined in our quoting process based on your design requirements.
