CNC Machining Surface Finishing Options
Choose from a range of finishes to improve the appearance, corrosion resistance, wear performance, and surface texture of CNC machined parts. Available options depend on the material, geometry, tolerance, and application requirements.
-
Anodizing
Improves corrosion resistance and provides a durable decorative finish for aluminum parts.
-
Bead Blasting
Creates a clean, uniform matte texture and reduces visible machining marks.
-
Powder Coating
Adds a durable colored coating with strong resistance to wear and corrosion.
-
Nickel Plating
Provides a smooth metallic layer for improved corrosion resistance and appearance.
-
Polishing
Reduces surface roughness and produces a smooth or reflective finish.
-
Brushing
Creates a consistent directional texture on stainless steel and other metal surfaces.

Tolerance Guide
Precision is critical in CNC machining. We define tolerances based on part function, material characteristics, and manufacturing feasibility to ensure optimal performance and cost balance.
Proper tolerance design helps reduce machining cost and improve production efficiency:
- Avoid over-tight tolerances where not functionally required
- Use standard tolerances for non-critical features
- Simplify complex geometries when possible
- Maintain uniform wall thickness for better stability
- Consider material behavior during machining
| Tolerance Type | Standard Tolerance (±mm) | Material | Cost Impact | Machining Feasibility |
| Non-critical Linear Dimensions | 0.10 | All metals & engineering plastics | Low | Standard 3-axis milling/turning; no special tooling required |
| Critical Linear Dimensions | 0.05 | Aluminum, Stainless Steel, Brass | Medium | Requires precision tooling & in-process inspection; avoid for brittle plastics (e.g., PEEK) |
| High-precision Linear | 0.02 / 0.03 | Aluminum 7075, Titanium, Stainless Steel | High | Needs 5-axis machining/CMM inspection; only for aerospace/medical critical components |
| Hole Positioning | 0.05 / 0.08 | All materials | Medium | Aligns with standard drill/reamer tolerances; tighter specs require reaming/boring |
| Surface Flatness | 0.05 / 0.10 | All metals | Medium | Thinner walls (< 2mm) require looser tolerances to prevent warping |
| Thread Pitch (Metric) | Class 2 / Class 3 | All machinable materials | Low/Medium | Class 2 = standard; Class 3 = high-load assemblies, requires thread grinding |
