There is no single 'CNC machining price' — every part is quoted on material, geometry, tolerance, quantity and finish. Understanding these drivers helps you budget accurately and cut cost without cutting corners. For the multi-axis version of the same question, see our 5-axis machining cost guide.
Material Cost
Raw material often accounts for 20–40% of part cost. Aluminum is economical; stainless steel and titanium are much more expensive. Sizing the stock to the part reduces waste.
Complexity & Set-up
Every additional set-up, operation and tool change adds cost. Parts machinable in fewer set-ups — or with 5-axis — are cheaper to produce. See our CNC machining services guide for the full cost model, including material, set-up, tolerance and finishing drivers.
We price and specify each part marking method separately, and the full breakdown sits in our part marking methods guide, including the salt spray and abrasion results we see on the floor.
Tolerances
Tight tolerances require slower cutting and more inspection, directly raising cost. Keep tight tolerance only on features that truly need it.
Volume & Economies of Scale
Per-part cost drops sharply with quantity because set-up and programming are spread across more units. Prototypes cost the most per piece; production runs cost the least.
Surface Finishing
Anodizing, plating and powder coating add cost. Choose the finish that meets functional requirements — a cosmetic finish on a hidden surface is wasted money.
Five Ways to Reduce Cost
Simplify geometry, relax non-critical tolerances, choose economical materials, batch orders, and involve your supplier early for DFM feedback.
