CNC milling service has become a cornerstone of modern manufacturing. Whether you need rapid prototyping or high-volume production, CNC milling offers unmatched accuracy, repeatability, and efficiency. At Langhe Casting, we deliver industry-grade CNC milling services tailored to meet the unique requirements of global clients in automotive, aerospace, medical, electronics, and industrial sectors.
CNC milling (Computer Numerical Control milling) is a subtractive manufacturing process that uses rotating multi-point cutting tools to remove material from a solid block (workpiece). It follows precise digital instructions generated from 3D CAD files to achieve complex geometries with tight tolerances.
High-precision machining (±0.01 mm or better)
Excellent surface finishes (Ra ≤ 0.8 μm achievable)
Multi-axis capabilities (3-axis, 4-axis, 5-axis)
Compatible with metals and plastics
Langhe Casting leverages advanced CNC machining centers and strict quality management to ensure superior results. Here’s why global manufacturers trust us:
Our state-of-the-art equipment delivers exceptional dimensional accuracy and consistency, ideal for both prototyping and production runs.
We work with a broad range of materials including:
| Metal Alloys | Plastic Materials |
|---|---|
| Aluminum (6061, 7075) | ABS |
| Stainless Steel (304, 316) | Nylon |
| Titanium | PEEK |
| Brass | Polycarbonate |
| Copper | PTFE (Teflon) |
With automated programming, toolpath optimization, and in-house tool libraries, we can complete projects in as fast as 1–3 days.
Whether it’s a single prototype or 10,000 production parts, our scalable CNC milling capabilities support flexible volume requirements.
Understanding the CNC milling workflow helps clients appreciate its accuracy and efficiency. Here’s a simplified breakdown:
CAD Model Creation: Engineers design the 3D model using CAD software.
CAM Programming: CAM tools convert the model into G-code instructions for the milling machine.
Material Setup: The workpiece is fixed to the machine bed using clamps or vises.
Machining: The machine cuts the material along specified toolpaths.
Finishing & Inspection: Parts undergo deburring, polishing, and strict dimensional checks.
Different machine configurations allow for varying degrees of freedom and complexity.
| Machine Type | Description | Best For |
|---|---|---|
| 3-Axis Milling | Cuts along X, Y, and Z axes | Simple geometries, flat parts |
| 4-Axis Milling | Adds rotation around the X-axis | Cylindrical cuts, slots |
| 5-Axis Milling | Moves in X, Y, Z + rotates around X and Y | Complex 3D surfaces, aerospace components |
CNC milling plays a crucial role in multiple industries. Some typical applications include:
Automotive: Engine components, transmission cases, housings
Aerospace: Structural parts, turbine blades, brackets
Medical: Surgical instruments, orthopedic implants, dental devices
Consumer Electronics: Enclosures, heat sinks, connectors
Industrial Equipment: Gearboxes, mounting plates, jigs and fixtures
