High-Precision CNC Deep Processing
Our CNC processing is optimized for thick-wall (2–20mm), large-size, and high-rigidity custom heavy-duty profiles, with core capabilities:
| Processing Type | Key Parameters | Advantages for Heavy Duty | Typical Uses |
|---|---|---|---|
| CNC Milling | ±0.02mm precision; 3D contour/slot/pocket milling | High rigidity, no deformation; fits complex heavy-duty structures | Machinery bases, load-bearing components |
| Drilling & Tapping | ±0.03mm hole precision; M5–M30 heavy-duty threads | Stable thread load-bearing; no stripped threads | Assembly connection points, mounting holes |
| Precision Cutting | ±0.1mm length tolerance; up to 12m long profiles | Burr-free, no structural damage to thick walls | Support beams, structural columns |
| Bending & Forming | ±0.5° angle precision; up to 15mm wall thickness | No cracks/deformation; maintains strength | Heavy-duty brackets, curved frames |
| Welding | Robotic TIG/MIG; weld strength ≥95% of base metal | Firm, corrosion-resistant; ensures high-load integrity | Welded frames, marine structures |
| Assembly & Deburring | Hardware installation + functional testing | Ready-to-install; improves safety/efficiency | Complete equipment frames |
- Specialized for heavy-duty profiles: Avoids deformation of thick-wall/high-rigidity materials
- Batch consistency: CMM inspection (±0.005mm) ensures uniform quality
- Structural protection: Machining/welding won't weaken 2xxx/7xxx series alloy strength
