Custom CNC Milled Aluminum Round Fin Heat Sink
| Item | Specification |
|---|---|
| Product Type | Custom 5‑axis CNC machined round finned aluminum heat sink component |
| Manufacturing Process | Solid billet 5‑axis CNC milling, one‑setup complete machining for thin‑wall fin structure |
| Material | 6063‑T5 aluminum alloy (alternative:6061‑T6,7075‑T6 aluminum upon request) |
| Max Outer Dimension | Φ118 mm * 42 mm |
| Fin Structure | Uniform curved thin cooling fins, fin thickness 1.2 mm, fin gap 2.0 mm |
| Critical Dimensional Tolerance | ±0.025 mm for fin flatness; circular runout ≤0.03 mm |
| Mounting Feature | Multi‑position counter‑bore mounting cut‑outs on central cavity for module assembly |
| Processing Characteristic | Multi‑direction cavity milling, thin‑wall fin profiling, full‑part deburring in single fixture |

FAQ
Q1: Can you manufacture this custom fin heat sink according to my 2D drawings or 3D CAD files?
A1: Yes, we provide full‑set OEM customization service. Please send your drawing files for DFM evaluation and formal quotation.
Q2: What alternative material options are available besides 6063‑T5 aluminum?
A2: 6061‑T6, 7075‑T6 aluminum alloys are available. Brass and stainless steel can also be selected for special‑working‑condition projects.
Q3: How do you control dimensional precision for these thin‑wall cooling fins?
A3: We adopt 5‑axis one‑setup CNC milling technology to avoid errors caused by repeated re‑clamping. Strict inspection is performed on fin flatness, gaps and runout to guarantee assembly performance.
Q4: Do you support prototype testing and mass‑volume production?
A4: Yes. We support prototype validation, small‑batch trial orders and large‑scale mass production, maintaining stable interchangeability for all finished parts.
Q5: What surface finishes can be applied to this aluminum heat sink?
A5: We supply clear anodizing, black hard‑coat anodizing, sandblasting, passivation and deburring services to improve corrosion resistance and surface quality.
Q6: What risks exist during thin‑fin CNC machining, and how do you handle them?
A6: Thin fins are prone to vibration and deformation during milling. We optimize cutting parameters and use one‑fixture processing to reduce fin distortion and keep consistent heat‑dissipation geometry.
