Processing case: Processing difficulties of aluminum parts with deep cavity and heat dissipation groove structure
A customer customized an aluminum alloy power supply heat dissipation shell for new energy vehicle control module. The main parameters are as follows:
Material: aluminum alloy 6061-T6
Size: 180mm × 120mm × 45mm
Features: There are multiple sets of parallel heat dissipation grooves in the middle (groove width 3mm, depth 12mm), and the bottom is a deep cavity structure
Precision requirements: groove depth consistency ±0.02mm, cavity bottom flatness ≤0.05mm
Surface treatment: anodizing (silver), requiring no water ripples, no knife marks, and no color difference
Processing difficulties:
The heat dissipation grooves are densely arranged, and it is very easy to produce chip accumulation, heat, and uneven groove bottom during processing;
The deep cavity structure is difficult to control vibration and tool cutting during processing;
If the size change is not well controlled after anodizing, the cover plate will be stuck or loose.

Use high-speed three-blade aluminum tool + spiral path programming to improve chip removal and finish;
Perform rough machining + intermediate annealing + fine machining before machining to release internal stress;
Use probe alignment + double-sided clamping reference control to ensure groove depth consistency;
Set 8μm size compensation before anode, and use special fixtures to prevent deformation after oxidation.

Finally, customers reported that this aluminum CNC milling part was assembled smoothly during the later assembly process and entered the mass delivery stage smoothly.
