Ask ten machine shops what a custom part costs and you will get ten different numbers — from under $30 for a simple turned part to several hundred dollars for a complex prototype, and sometimes under $5 per piece at volume. Both answers can be honest. Per-part pricing in precision CNC machining is not a menu price; it is the result of setup time, cycle time, material, tolerances, finishing, and order quantity all interacting at once. This guide gives you realistic per-part cost ranges for 2026, breaks down exactly what sits behind the number, and shows how to bring your own figure down before you ever request a quote.
For a moderately complex part — say an aluminum 6061 bracket with a few pockets and drilled holes, at general tolerances of ±0.05 mm — buyers in 2026 typically see per-part prices inside these bands:
| Order quantity | Typical per-part price | What dominates the cost |
|---|---|---|
| 1–5 pieces | $80 – $300 | Setup and programming |
| 10–50 pieces | $30 – $90 | Setup amortization + cycle time |
| 100–500 pieces | $8 – $40 | Cycle time and material |
| 1,000+ pieces | $3 – $15 | Cycle time, material, finishing |
A simple turned aluminum spacer will sit below these ranges; a 5-axis titanium aerospace fitting will sit far above them. That spread is exactly why understanding the cost structure matters more than any single number. If you want a benchmark for your own drawing, a shop that explains its CNC machining cost logic openly will always give you a more predictable quote than one that hides behind a flat hourly rate.
Every machining quote, however it is formatted, follows the same underlying structure:
Total cost ≈ Setup & programming + (Cycle time × Hourly rate) + Material + Finishing + Overhead & risk margin
Setup is a fixed, one-off engineering cost: CAM programming, fixturing, tool selection, and first-article prove-out happen once per job and are then divided across the quantity. That is why one piece looks expensive and a hundred pieces look cheap — the setup burden per part collapses as volume rises. Cycle time, by contrast, is variable and driven almost entirely by your part’s geometry, material, and tolerance demands.
Hourly rates provide context, but treat them as background rather than a pricing shortcut:
| Machine type | Typical hourly rate (US/EU shops) | Best suited for |
|---|---|---|
| 3-axis CNC milling | $35 – $80 | Prismatic parts, pockets, plates |
| 4-axis machining | $60 – $125 | Multi-face parts, fewer setups |
| 5-axis machining | $100 – $200+ | Complex contoured geometry |
| CNC turning | $35 – $85 | Shafts, bushings, threaded parts |
Two practical notes here. First, a higher hourly rate can mean a lower total cost if a 5-axis machine finishes in one setup what a 3-axis machine needs three setups to do. Second, comparable machining work in China typically costs 40–60% less than in the US, which is the main economic reason buyers offshore production parts once designs are stable.
Material affects price twice: once through stock cost, and again — usually more strongly — through machinability. Slower cutting speeds, higher tool wear, and heat control on difficult alloys stretch cycle time far beyond the raw material surcharge.
| Material | Typical stock cost | Machinability | Relative machining time |
|---|---|---|---|
| Aluminum 6061 / 7075 | $5 – $15/kg | Excellent | 1× (baseline) |
| Mild / alloy steel | $2 – $5/kg | Good | 1.2 – 1.5× |
| Brass / copper | $8 – $15/kg | Excellent | ~1× |
| Stainless 304 / 316L | $15 – $25/kg | Moderate | 1.5 – 2.5× |
| Titanium Ti-6Al-4V | $30 – $50/kg | Poor | 3 – 5× |
| PEEK | $100+/kg | Good, but heat-sensitive | 1.5 – 2× |
Specific features cost money, not “complexity” in the abstract. Deep pockets beyond three times the tool diameter, thin walls that vibrate, tight internal radii that force small cutters, undercuts, and multi-face features all slow feeds, add tool changes, or demand extra setups. A part that looks only slightly harder on screen can take twice the machine time.
Tolerance is priced roughly in steps. General ±0.1 mm work is the baseline. Calling ±0.01–0.025 mm on a feature typically multiplies its machining cost two to five times, because the shop must use shallower finishing passes, slower feeds, and more measurement. At ±0.005 mm and tighter, expect secondary processes such as precision surface grinding or wire EDM, plus CMM inspection time. Apply tight tolerances only to the features that genuinely need them — a blanket tight tolerance across a whole drawing is one of the most expensive habits in part design.
Setup and programming commonly run $100–$300 per job before a single chip is cut. Spread over one part, that is the whole price; spread over five hundred, it disappears into the noise. On a prototype run, setup frequently accounts for 30–90% of what you pay per part, which is why prototype prices are a terrible predictor of production prices.
Anodizing, electroplating, powder coating, passivation, bead blasting, and heat treatment each add per-lot fees plus handling time. Heat treatment can also introduce distortion that forces re-inspection or rework. Sourcing machining and finishing from one supplier avoids the double-handling markup that appears when parts shuttle between subcontractors.
CMM reports, first-article inspection, and material certificates all add real labor. For medical and aerospace programs they are non-negotiable; for a fixture plate they are often wasted money. Specify the documentation you actually need.
To make the ranges concrete, here is how the drivers combine on three typical parts. Figures are illustrative industry-typical bands, not quotations:
Notice the pattern: quantity moves the price more than any negotiation ever will, and material plus tolerance choices can outweigh quantity entirely at the high end.
Most slow or inflated quotes come from incomplete information. Send these six items and a competent shop can price your part without a single follow-up email:
When you request a CNC machining quote from ANOK, the engineering team reviews your drawing for manufacturability before pricing it. That DFM pass routinely finds savings — a relieved tolerance here, a larger corner radius there, a smarter stock size — that reduce cost before production rather than after a failed first article.
Lower hourly rates are only half of the offshore advantage. The other half is consolidation. When CNC milling, turning, surface grinding, wire EDM, coating, and assembly sit under one roof, parts stop accumulating a fresh margin at every subcontractor handoff, and lead time shrinks along with cost.
ANOK Precision Manufacturing in Shenzhen has run this one-stop model since 2007 under ISO 9001:2015 certification. The shop holds tolerances down to ±0.002 mm and mirror finishes to Ra 0.2, machines everything from aluminum and brass to titanium, Inconel, and PEEK, and ships custom parts to medical, aerospace, automation, and food-equipment programs worldwide — from one-off prototypes to production batches.
Why does a single prototype cost so much more per part?
Because setup and programming are indivisible. The same CAM work, fixturing, and prove-out happen whether you order one piece or a thousand, and on a one-piece order that entire cost lands on a single part.
What is the cheapest material and process combination?
Aluminum 6061 on a 3-axis mill, or brass on a CNC lathe, at general tolerances. Both materials cut fast, wear tools slowly, and rarely need secondary work.
Do tight tolerances always raise the price?
Only where they are applied. A single ±0.01 mm bore on an otherwise loose drawing costs relatively little; blanketing the whole part with tight callouts is what multiplies machining and inspection time.
How can I lower my per-part cost without switching suppliers?
Relax non-critical tolerances, enlarge internal corner radii, avoid deep thin-walled features, standardize finishes, and batch your orders. A DFM review before quoting usually finds more savings than price negotiation after it.
Custom precision machining costs anywhere from a few dollars to several hundred dollars per part, and the difference is almost never arbitrary. Setup amortization, cycle time, material machinability, tolerance steps, finishing, and volume explain nearly all of it. Control those six levers at the design stage and you control the price. Send your CAD and drawing to ANOK for a DFM review and a detailed, line-item quote — you will know exactly what your part costs, and why.
