Custom CNC Machined Aluminum Adapter Block for Automotive Applications
This CNC-machined aluminum adapter block is a precision-engineered component designed to connect, align, or convert interfaces between mechanical parts and assemblies. Made from high-quality aluminum alloy, the part offers excellent strength-to-weight ratio, corrosion resistance, and dimensional stability, making it ideal for applications that require lightweight, durable, and high-precision coupling elements.
Our aluminum adapter blocks are widely used in industries such as automotive, automation, robotics, testing equipment, consumer electronics, and instrumentation. Whether it's adapting between two shaft sizes, interfacing between housings and fixtures, or serving as a spacer for dynamic assemblies, this part is built for structural efficiency and reliable performance.
Key Features
- Material: Aluminum alloy (6061, 7075, etc.)
- Process: CNC turning and milling
- Surface Finish: Natural, anodized, brushed, or polished (custom options available)
- Function: Adapter, spacer, connector, or sleeve in mechanical assemblies
- Tolerance: Custom precision (±0.01mm available)
- Customization: Full support for drawings (PDF, STEP, DWG) or samples
- Certification: ISO9001 certified facility
- Lead Time: Approximately 14 working days
Each block is CNC machined from aluminum bars or billets, ensuring tight tolerances, clean surface finishes, and consistent dimensions across batches. The natural aluminum surface shown here is standard, but we also offer anodizing (various colors), sandblasting, brushing, or polishing to meet aesthetic or functional needs.
Standard sizes are approximately 20mm in length and 10mm in diameter, though full dimensional customization is available based on client drawings or design requirements. Tolerances, surface roughness, chamfers, inner contours, or other features can be freely adjusted per your specifications.
