Advanced CNC machining workshop for precision liquid cooling components
Machining Processes
| Process | Description |
|---|---|
| Mill‑Turn CNC Machining | Combined turning and milling operations in a single setup for complex geometries |
| CNC Turning | High‑precision turning for cylindrical and threaded components |
| Swiss‑Type Lathe | High‑efficiency machining for small‑diameter, long, and complex parts |
Mill-Turn CNC Center
Swiss-Type Automatic Lathe
We are equipped with advanced CNC mill‑turn centers, CNC lathes, and Swiss‑type automatic lathes, capable of completing turning, milling, drilling, tapping and other operations in a single setup for complex structural parts, reducing clamping cycles and ensuring dimensional accuracy and positional tolerance.
Available Materials
| Material | Applications |
|---|---|
| SS304 / SS316L Stainless Steel | Corrosion‑resistant components for liquid cooling systems |
| Nickel‑Plated Brass | Threaded fittings and adapters requiring good machinability and corrosion resistance |
| 6061 Aluminum Alloy | Lightweight manifold bodies and structural components |
Based on application scenarios of liquid cooling systems (coolant media, operating temperature, corrosion resistance requirements), we recommend the most suitable material solutions and provide complete material certificates.
Dimensional Tolerances
| Dimension Range | Tolerance |
|---|---|
| 0 – 3mm | ±0.02 |
| 3 – 6mm | ±0.03 |
| 6 – 20mm | ±0.03 |
| 20 – 50mm | ±0.06 |
| > 50mm | ±0.07 |
| Angle (unless specified) | ±0.5° |
Critical fit tolerances can be further tightened per customer drawing requirements to meet high‑precision assembly needs.
Surface Quality
| Parameter | Specification |
|---|---|
| Standard Surface Roughness | Ra ≤ 1.6μm |
| Critical Bore Roughness | Ra ≤ 0.8μm (per drawing) |
| Surface Finish | Free of burrs, scratches, oil and water stains |
After machining, all parts undergo cleaning and deburring processes to ensure internal bores and flow channels are clean and residue‑free, meeting the cleanliness requirements of liquid cooling systems.
Surface Finishing
| Material | Treatment |
|---|---|
| Stainless Steel (SS304/SS316L) | Electropolishing + Passivation |
| Aluminum Alloy (6061) | Anodizing (clear or dyed) |
- Electropolishing: Improves surface finish, reduces micro‑roughness, and enhances corrosion resistance
- Passivation: Forms a dense oxide film on stainless steel surfaces for improved corrosion resistance
- Anodizing: Creates an oxide layer on aluminum surfaces for enhanced wear and corrosion resistance
Material Control
| Parameter | Specification |
|---|---|
| Sulfur Content (Stainless Steel) | < 0.03% |
| Hardness (SS304) | HV270 min |
| Salt Spray Resistance | Neutral Salt Spray 96 hrs, no corrosion |
Strict material control ensures reliability and corrosion resistance of components throughout long‑term operation in liquid cooling systems.
Marking & Packaging
| Item | Method |
|---|---|
| Marking | Laser Marking (Part No. / Logo / Spec ID) |
| Packaging | Tray Packaging (Anti‑static bag + foam padding + export carton) |
Finished parts in anti-static tray packaging
Quality Control
CMM Coordinate Measuring Machine
Vision Inspection System
| Inspection Stage | Details |
|---|---|
