Capabilities for Prototype CNC Machining
| Capabilities | Standards & Quality Control |
|---|---|
|
Processes: 3-axis / 4-axis / 5-axis milling; CNC turning; mill-turn |
Inspection tools: CMM; height gauge; pin gauges; calipers/micrometers; thread gauges |
|
Max part size: 600 × 400 × 300 mm (larger upon review) |
Reports (optional): FAI / CMM inspection report; critical-dimension report |
|
Min feature size: 0.2 mm (feature-dependent) |
Datums & critical dims: reviewed before machining; DFM notes provided with quote |
|
Tolerance (typical / tight): ±0.05 mm / ±0.02 mm (tight tolerance upon review) |
Measurement approach: first-piece verification; critical-dimension check; final inspection as required |
|
Surface finish: Ra 3.2 μm (as-machined); bead blast; anodize; polishing (Ra 1.6 μm achievable on selected surfaces) |
Finishing control: appearance vs functional intent aligned; masking and consistency managed per requirements |
|
Quantity: 1–500 pcs (prototype to low-volume) |
IP protection: NDA available; secure file handling (as required) |
|
Materials (metals): Aluminum 6061/7075/2024; Stainless steel 303/304/316; Tool steel P20/H13/A2/D2 |
Material control: production-intent material selection supported; substitutions confirmed before machining |
|
Materials (plastics): ABS / PC / POM / PA6 / PA66 / PEEK / PMMA (or equivalents) |
Drawing standards: GD&T supported; datum scheme reviewed for inspectability |
Notes: Tighter tolerances, thin-wall features, and complex geometry are subject to engineering review. Critical dimensions should be clearly marked on the drawing for inspection planning.
