A Guide to Aluminum Machined Parts

Machining aluminum parts requires careful consideration of several factors to achieve accurate and high-quality results. Here are the general steps involved in machining aluminum parts from design till delivery:

1. Design and Planning:

  • Begin by creating or obtaining a detailed design, CAD model and technical drawings of the aluminum part.
  • Determine the dimensions, tolerances, and required surface finishes.
  • Consider the machining process and select appropriate cutting tools and machining techniques.

2. Material Selection:

  • Choose the right aluminum alloy based on the specific requirements of the part, such as strength, corrosion resistance, or heat conductivity.
  • Popular aluminum alloys for machining include 6061, 7075, and 2024.

3. Setup the Machining Equipment:

  • Ensure the machine tools, such as lathes, mills, or CNC machines, are properly set up and calibrated.
  • Mount the aluminum workpiece securely on the machine’s workholding device, such as a vise or fixture.

4. Tool Selection:

  • Select the appropriate cutting tools for aluminum machining. Carbide or high-speed steel (HSS) tools are commonly used.
  • Consider using sharp tools with high helix angles to efficiently evacuate chips and reduce heat buildup.

5. Cutting Parameters:

  • Determine the cutting speed, feed rate, and depth of cut based on the specific aluminum alloy, tooling, and machine capabilities.
  • Consult cutting speed charts or machining databases for recommended parameters, or conduct tests to optimize settings.

6. Coolant and Lubrication:

  • Use coolant or lubricants during the machining process to dissipate heat, prolong tool life, and improve surface finish.
  • Consider using water-soluble coolants or cutting fluids specifically formulated for aluminum.

7. Machining Operations:

  • Begin with roughing operations to remove excess material efficiently. This can involve facing, turning, or milling operations.
  • Follow up with finishing operations to achieve the desired dimensions and surface finish. These can include profiling, drilling, or threading.

8. Chip Control:

  • Pay attention to chip evacuation to prevent chip buildup and potential tool damage. Use proper chip-breaking techniques and ensure adequate chip clearance.

9. Quality Control:

  • Regularly measure and inspect the machined parts using precision measurement tools, such as calipers, micrometers, or CMMs.
  • Verify dimensions, tolerances, and surface finish to ensure compliance with design specifications.

10. Surface Finishing (Optional):

  • Consider post-machining surface finishing processes such as deburring, polishing, anodizing, painting or even Cr³ treatment to improve aesthetics and functionality.

11. Cleaning and Packaging:

  • Thoroughly clean the machined parts to remove any cutting fluid, chips, or contaminants.
  • Properly package the finished aluminum parts to protect them during transportation or storage.

Remember, the specific machining process may vary depending on the complexity of the part, the chosen machining technique (CNC or manual), and the available equipment. It’s important to refer to the manufacturer’s guidelines, tooling recommendations, and best practices for machining aluminum.
