Product Description

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
Product Weight	0.65
Surface Roughness	Ra 1.6‑Ra3.2, fin surface high‑precision milling for optimal thermal exchange
Machining Note	One‑clamp 5‑axis milling minimizes thin‑fin vibration & deformation; ensures fin parallelism and dimensional consistency. Eliminates repeated re‑clamping errors for complex curved fin geometry.
Surface Treatment Options	Clear anodizing, black hard‑coat anodizing, sandblasting, passivation, custom anti‑corrosion coating
Production Capacity	Prototype development, small‑batch & mass volume production
Applicable Industries	LED high‑power lighting, power electronics, communication module, new‑energy controller, automotive lighting components

OEM custom round fin heat sink manufactured by 5‑axis CNC milling from solid aluminum billet. Single‑fixture machining guarantees high precision of thin curved cooling fins and central mounting cutouts. Thin‑wall fin design delivers excellent heat dissipation performance. Light‑weight aluminum structure fits LED lighting, power electronic and new‑energy equipment. Supports custom modification per 2D/3D drawings.

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.
