Product Features & Advantages

✅ Material Diversity (Core Highlight)

We can machine multiple metal materials to match different working environments:

1. 6061 Aluminum Alloy: Good machinability, moderate strength, excellent corrosion resistance, low cost. Ideal for general industrial structural parts.
2. 7075 Aluminum Alloy: High tensile strength, close to steel, ultra-lightweight. Perfect for aerospace & robot components with high load requirement.
3. 304 / 316 Stainless Steel: Anti-rust & corrosion resistant, suitable for humid, chemical working conditions.
4. Brass: Good wear resistance & electrical conductivity, used for sealing and conductive fittings.

📌 Key Note: Material selection directly affects part weight, strength, cost and service life. Our engineering team can recommend the best material based on your working condition.

✅ Machining Characteristics

• Turn-mill composite process: Complete turning of inner/outer cylinder, milling of mounting lugs, drilling & tapping of angled holes in single clamping.
• Avoid repeated re-clamping errors, ensure high coaxiality of the cylinder bore and precise position of mounting holes.
• Complex asymmetric structure can be realized without multiple fixtures.
• Strict deburring treatment to remove sharp edges for safe assembly.

✅ Product Core Advantages

1. Integrated Structure Design: Cylinder body, mounting ears and positioning flange processed as one piece. No welding assembly, higher rigidity and stability.
2. High Precision Mating: The positioning flange and inner bore maintain tight tolerance, ensuring accurate alignment during equipment assembly.
3. Lightweight & High Rigidity: Aluminum version reduces overall equipment weight while maintaining enough structural strength.
4. Full Customization: Modify length, diameter, hole layout, flange size according to your CAD drawings or samples.

Application Scenarios

• Humanoid robot joint housing & robot arm structural connectors
• Industrial UAV arm and optoelectronic pod support cylinder
• Aerospace lightweight sensor mounting bracket
• Automation machinery positioning connection parts
• Optical testing equipment structural shell
