For this project, our team completed a custom CNC machining<\/strong> solution for a long-term customer in Germany. The aluminum housing, used in an industrial automation system, required high precision, stable flatness, and consistent cosmetic quality<\/strong>. To ensure the final parts met all functional requirements, we began with a complete DFM drawing analysis<\/strong>, followed by a detailed machining plan.<\/p>\n

\n

Drawing Analysis & Key Findings<\/strong><\/h2>\n

During the initial review, we identified several manufacturability issues. First<\/strong>, the thin-walled 1.5 mm sections posed a risk of deformation during milling. Additionally<\/strong>, multiple \u00b10.02 mm tolerance holes required a dedicated finishing process. Moreover<\/strong>, the 120 mm surface flatness requirement (\u22640.03 mm) meant we needed to control internal stress during machining. Lastly<\/strong>, sharp internal corners had to be optimized to match CNC tool geometry.<\/p>\n

These insights allowed us to propose small design adjustments that improved machinability while fully maintaining the part\u2019s function.<\/p>\n

\n

Machining Challenges & Solutions<\/strong><\/h2>\n

1. Thin-Wall Deformation Control<\/strong><\/h3>\n

To avoid vibration and deformation, we applied multi-step roughing, semi-finishing, and finishing<\/strong>. We also used custom soft jaws and temporary support tabs.
\u27a1 Result:<\/strong> Deflection kept within 0.01\u20130.015 mm.<\/p>\n

2. \u00b10.02 mm Hole Accuracy<\/strong><\/h3>\n

We combined pilot drilling and reaming<\/strong>, operated in a temperature-controlled workshop, and executed 100% CMM inspection.
\u27a1 Result:<\/strong> All hole tolerances met assembly requirements.<\/p>\n

3. Flatness on Wide Surface<\/strong><\/h3>\n

We applied stress-relief rough machining<\/strong>, rested the parts after roughing, and optimized tool paths for heat control.
\u27a1 Result:<\/strong> Flatness achieved \u22640.02 mm.<\/p>\n

4. Cosmetic Surface Finish<\/strong><\/h3>\n

To satisfy European quality expectations, we implemented uniform milling patterns, bead blasting, and RoHS-certified clear anodizing.
\u27a1 Result:<\/strong> Consistent aesthetic appearance across batches.<\/p>\n

\n

Benefits for the Customer<\/strong><\/h2>\n

Through our optimized machining workflow, the customer gained:<\/p>\n

    \n
  • \n

    Higher precision and reliability<\/strong><\/p>\n<\/li>\n

  • \n
