Machining Processes

ProcessDescription
Mill‑Turn CNC MachiningCombined turning and milling operations in a single setup for complex geometries
CNC TurningHigh‑precision turning for cylindrical and threaded components
Swiss‑Type LatheHigh‑efficiency machining for small‑diameter, long, and complex parts

Mill-Turn CNC Center

Swiss-Type Automatic Lathe

Our CNC machining equipment includes mill-turn centers, CNC lathes and Swiss-type automatic lathes. Depending on part design, these machines can perform turning, milling, drilling and tapping operations to manufacture complex components with controlled dimensions and positional accuracy. Combining multiple operations in a suitable setup can reduce repeated clamping and help maintain consistency across production batches.

Available Materials

MaterialApplications
SS304 / SS316L Stainless SteelCorrosion‑resistant components for liquid cooling systems
Nickel‑Plated BrassThreaded fittings and adapters requiring good machinability and corrosion resistance
6061 Aluminum AlloyLightweight manifold bodies and structural components

Material selection depends on the coolant medium, operating temperature, corrosion requirements and component design. We support stainless steel, aluminum alloy and nickel-plated brass options for suitable liquid cooling components. Material certificates can be provided according to project requirements.

Dimensional Tolerance Capabilities

Dimension RangeTolerance
0 – 3mm±0.02
3 – 6mm±0.03
6 – 20mm±0.03
20 – 50mm±0.06
> 50mm±0.07
Angle (unless specified)±0.5°

Tolerances depend on part geometry, material, dimensions and machining requirements. Tighter tolerances for critical interfaces can be reviewed against customer drawings and confirmed during technical evaluation.

Surface Quality

ParameterSpecification
Standard Surface RoughnessRa ≤ 1.6μm
Critical Bore RoughnessRa ≤ 0.8μm (per drawing)
Surface FinishFree of burrs, scratches, oil and water stains

Machined parts undergo deburring and cleaning as specified to remove machining residues and loose particles from accessible surfaces, bores and flow channels. Additional cleanliness requirements can be reviewed according to the liquid cooling application and customer specifications.

Surface Finishing

MaterialTreatment
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

ParameterSpecification
Sulfur Content (Stainless Steel)< 0.03%
Hardness (SS304)HV270 min
Salt Spray ResistanceNeutral Salt Spray 96 hrs, no corrosion

Strict material control ensures reliability and corrosion resistance of components throughout long‑term operation in liquid cooling systems.
