♪ I. Aluminum Plate CNC Flat Cutting
1 Process Description
CNC flat cutting uses computer-controlled machine tools for high-precision 2D shape cutting on aluminum plates. Ideal for panels, base plates, heat sinks, nameplates, and structural components.
2 Applicable Materials
- ♪ Aluminum alloys: 5052, 6061, 7075
- ♫ Thickness: 0.5mm – 25mm
- ♩ Material states: Annealed (O), half-hard (H32/H34), hard (H112)
3 Process Capabilities
| Parameter | Capability Range | Notes |
|---|---|---|
| Cutting Accuracy | ±0.05mm – ±0.10mm | Standard ±0.10mm, precision up to ±0.05mm ♪ |
| Max. Working Size | 1500×3000mm | Customizable ♫ |
| Min. Hole Diameter | ≥ material thickness | Thinner plates allow smaller holes ♩ |
| Min. Slot Width | ≥1.0mm | Tool diameter dependent 𝄞 |
| Surface Roughness | Ra1.6 – Ra3.2 | Further finishing available (brushing/polishing) ♬ |
| Max. Cutting Thickness | 25mm (aluminum plate) | Beyond requires special process ♪ |
4 Process Flow
| Step | Process | Description |
|---|---|---|
| 1 | Drawing Receipt | 2D/3D drawings (DXF/DWG/STEP) ♪ |
| 2 | Programming & Nesting | Tool paths, optimize nesting ♫ |
| 3 | Material Preparation | Specified grade/thickness, check flatness ♩ |
| 4 | CNC Cutting | Cutting fluid cooling to reduce deformation 𝄞 |
| 5 | Deburring | Manual or vibratory finishing ♬ |
| 6 | Inspection | Calipers/CMM, visual inspection ♪ |
| 7 | Post-Processing (optional) | Brushing, sandblasting, anodizing, painting ♫ |
♫ II. Sheet Metal Enclosure Fabrication
1 Process Description
Laser/punching blanking, CNC bending, welding and assembly to form 3D enclosures, cabinets and housings.
2 Applicable Materials
- ♪ Cold-rolled steel: SPCC, SGCC (galvanized)
- ♫ Stainless steel: SUS304, SUS316
- ♩ Aluminum plate: 5052, 6061
- 𝄞 Thickness: 0.8mm – 6.0mm
3 Process Capabilities
| Parameter | Capability Range | Notes |
|---|---|---|
| Blanking Accuracy | ±0.10mm | Laser / CNC punch ♪ |
| Bending Accuracy | ±0.20° / ±0.15mm | CNC press brake ♫ |
| Welding Methods | TIG / MIG / Spot welding | Material dependent ♩ |
| Max. Working Size | 2000×4000mm | Blanking equipment dependent 𝄞 |
| Surface Finishing | Spray painting / powder coating / black oxide / zinc plating / anodizing | As required ♬ |
| IP Protection Rating | IP54 / IP65 / IP66 | With proper sealing design ♪ |
4 Process Flow
| Step | Process | Description |
|---|---|---|
| 1 | Drawing Flattening | Flatten 3D → 2D blanking layout ♪ |
| 2 | Blanking | Laser / CNC punch, accuracy ±0.10mm ♫ |
| 3 | Deburring | Grind cutting edges ♩ |
| 4 | Bending | CNC press brake, angle control ±0.20° 𝄞 |
| 5 | Welding (if applicable) | TIG / MIG / spot welding ♬ |
| 6 | Grinding | Smooth weld seams ♪ |
| 7 | Surface Finishing | Painting / powder coating / anodizing / zinc plating ♫ |
| 8 | Assembly (optional) | Hinges, latches, PCBA, connectors ♩ |
| 9 | Inspection | Dimensional/visual/assembly/IP test 𝄞 |
5 Welding Process Highlights
- ♪ Thin sheets (≤2mm): Spot/intermittent welding to reduce distortion
- ♫ Medium-thick sheets (2-6mm): Continuous TIG welding for strength
- ♩ Stainless steel / aluminum: TIG with appropriate filler wire
- 𝄞 Distortion control: Fixtures + skip/symmetrical welding + post leveling
