How Much Does CNC Machining Cost Per Part? Price Ranges by Material, Quantity & Complexity (2026)

How Much Does CNC Machining Cost Per Part? Complete Price Guide 2026

Quick answer: CNC machining costs range from $5 for simple turned aluminum spacers to $500+ for complex 5-axis titanium aerospace parts. For a typical prototype aluminum bracket (50x50x20mm), expect $30–80 per part at quantity 1, dropping to $8–20 at quantity 100. Material choice, tolerance requirements, and surface finish are the three biggest cost drivers beyond quantity.

How to Estimate CNC Part Cost Without a Quote

Formula: Base Rate × Material Multiplier × Complexity Factor × (1 + Tolerance Premium) ÷ Quantity Factor

  • Base rate: $30–60/hr for 3-axis, $50–90/hr for 5-axis (China FOB 2026)
  • Material multiplier: 1.0 (aluminum) to 5.0 (titanium) — see table above
  • Complexity factor: 0.5 (simple) to 3.0 (5-axis complex)
  • Tolerance premium: 0% (standard) to 120% (±0.005mm)
  • Quantity factor: ~0.7x at 10 pcs, ~0.4x at 100 pcs, ~0.25x at 1000 pcs

Example calculation: Aluminum bracket, 3-axis, 50 pcs, standard tolerance → $40/hr × 1.0 × 1.0 × 1.0 × 0.5 (quantity factor for 50 pcs) × 0.5 hrs machining time ≈ $10 per part

CNC Machining Cost Formula Buyers Can Use

A practical CNC quote is usually built from material cost + programming + setup + machine time + tooling risk + finishing + inspection + packaging + shipping. Quantity changes the price because programming and setup are spread across more parts, while material, machining time, finishing, and inspection still scale with each unit.

Cost DriverWhat Increases ItHow Buyers Reduce It
MaterialLarge stock size, titanium, stainless 316, PEEK, special certificatesAllow equivalent grades, standard stock sizes, and clear material cert requirements
Setup and programmingMany faces, tight datum control, complex toolpathsCombine features logically, mark only critical dimensions, avoid unnecessary tight tolerances
Machine timeDeep pockets, thin walls, hard materials, small cuttersIncrease corner radii, reduce depth where possible, use manufacturable wall thickness
FinishingCosmetic anodizing, polishing, plating, masking, color matchingSeparate cosmetic from non-cosmetic surfaces and provide finish samples when needed
InspectionCMM reports, FAI, 100% inspection, complex GD&TSpecify which features need formal reporting and which can use standard inspection
ShippingUrgent air freight, heavy parts, DDP service, special packagingShare target delivery date early and confirm whether FOB, CIF, or DDP is required

Example RFQ Scenarios and What Changes the Price

RFQ ScenarioLikely Quote SensitivityBuyer Tip
1 aluminum prototype housing, bead blasted and anodizedSetup, finish minimum charge, and cosmetic handling drive costAsk for as-machined and anodized options if function matters more than appearance
100 stainless steel shafts with bearing fitsTurning time, concentricity, and inspection frequency drive costCall out bearing surfaces clearly and avoid tight tolerance on non-functional lengths
20 titanium brackets with multiple angled holesMaterial, tool wear, and multi-axis setup dominateConfirm whether 3+2 machining is acceptable instead of full simultaneous 5-axis
500 plastic fixtures for production supportMaterial stability, batch consistency, and packaging drive riskSpecify temperature exposure and whether Delrin, nylon, or PEEK is truly required

What to Include to Get a More Accurate Price

  • 3D CAD file plus 2D drawing if tolerances matter.
  • Material grade, quantity, surface finish, and target delivery date.
  • Critical dimensions, threads, inserts, cosmetic surfaces, and inspection requirements.
  • Expected repeat quantity so setup and fixture choices can be quoted realistically.
  • Shipping country and preferred trade term such as FOB, CIF, or DDP.
