Note: Prices vary based on complexity, material, and tolerances.
Factors That Affect CNC Machining Cost
1. Material Selection
Material costs significantly impact your CNC machining price:
| Material | Relative Cost | Common Grades |
|---|---|---|
| Aluminum | $ | 6061, 7075, 2024 |
| Steel | $$ | 1018, 4140, A36 |
| Stainless Steel | $$$ | 303, 304, 316 |
| Titanium | $$$$ | Grade 2, Grade 5 |
| Brass | $$ | C360, C464 |
| Plastics | $ - $$ | POM, PEEK, Nylon |
Cost-saving tip: Aluminum 6061 offers an excellent balance of mathe regionbility, strength, and cost for most applications.
2. Part Complexity
Complexity directly affects CNC machining cost per hour:
- Simple parts (2-3 axis): Lower setup time, faster machining
- Moderate complexity (3-4 axis): Requires more programming time
- Complex parts (5-axis): Highest precision, longest machining time
Features that increase cost:
- Tight tolerances (±0.001" or tighter)
- Complex internal geometries
- Thin walls or delicate features
- Multiple setups required
- Special surface finishes
3. Tolerance Requirements
Tighter tolerances mean higher CNC machining costs:
| Tolerance Level | Cost Multiplier | Typical Applications |
|---|---|---|
| Standard (±0.005") | 1x | General purpose parts |
| Precision (±0.002") | 1.5x - 2x | Fitting parts |
| High Precision (±0.0005") | 3x - 5x | Aerospace, medical |
4. Production Volume
Volume dramatically affects CNC machining pricing:
- Prototype (1-10 parts): Higher per-part cost due to setup
- Small batch (10-100): Moderate pricing, good for testing
- Medium batch (100-1,000): Economies of scale begin
- Large batch (1,000+): Lowest per-part cost
5. Surface Finish Requirements
Surface treatments add to CNC machining cost:
| Finish Type | Additional Cost | Purpose |
|---|---|---|
| As-machined | Base price | Functional parts |
| Bead blasting | +$5-15/part | Uniform appearance |
| Anodizing | +$10-30/part | Corrosion resistance |
| Powder coating | +$15-40/part | Durability, color |
| Polishing | +$20-50/part | Aesthetic parts |
CNC Machining Cost Per Hour
Understanding CNC machining cost per hour helps estimate project budgets:
Machine Hourly Rates
