| CNC Machining Parameters | Standard / Commercial Grade | Precision / High-Wear Grade |
|---|---|---|
| CNC Tolerances (ISO 2768) | ±0.1 mm to ±0.05 mm (Medium to Fine) | ±0.01 mm to ±0.005 mm (Critical Fits) |
| Surface Finish (Roughness) | Ra 3.2 µm to Ra 1.6 µm (As-Machined) | Ra 0.8 µm to Ra 0.4 µm (Bearing & Sliding Surfaces) |
| Surface Treatment Options | Clear/Color Anodizing, Black Oxide, Sandblasting | Hard Anodizing, Electroless Nickel, PTFE Coating |
| Accepted CAD File Formats | STEP (.stp), IGES (.igs) for 3D Geometry | PDF, DWG for 2D Critical Tolerances & Thread Specs |
| Lead Time Optimization Factors | Standard Alloy Selection, Single-Axis Setup | Multi-Axis Mill-Turn, Custom Inspection & FAI |
!
- • Undefined Mechanical Fits: Failing to specify shaft-hole clearances or interference fits often forces costly production rework.
- • Vague Material Specifications: Calling out "Aluminum" or "Stainless" without an exact grade (e.g., 6061-T6, SUS304) causes engineering ambiguity.
- • Omitted Edge Breaks & Radii: Sharp internal corners restrict tool paths and raise stress concentrations; specify acceptable fillets early.
- • Missing Datum References: Operating without defined geometric dimensioning and tolerancing (GD&T) baselines creates inspection mismatches.
- • Incomplete Post-Processing Specs: Failing to detail precise plating thicknesses can compromise parts during automated assembly.
- • Outdated Engineering Files: Submitting mismatched 3D models and 2D blueprints delays engineering review and formal quotation.
Standard alloys like Aluminum 6061 or Stainless 304 are processed immediately. Specialty medical or food-safe polymers (e.g., PEEK, POM) may require raw stock lead times if not pre-allocated.
Parts requiring deep pockets, ultra-thin walls, or multi-axis repositioning demand advanced programming and specialized fixtures, which extends active machine cycle times.
Strict validation protocols—such as complete CMM coordinate reports, First Article Inspection (FAI), and raw material traceability certifications—add dedicated quality assurance time to shipping windows.
