CNC Machining for Startups — Real Cost Breakdown for Ireland

The two cost components

Every CNC quote, anywhere, is built from two components: setup cost and per-unit cost. Understanding the split is the difference between a smart purchase and a bad surprise.

Setup cost is everything that happens once before any chips fly: the CAM programmer reading your CAD file, generating toolpaths, simulating the cut, picking the right tool order, writing the program, then the machinist fixturing the raw stock, zeroing the machine, and running a first test cut. For a moderately complex part, setup is typically 2 to 6 hours of skilled labour.

Per-unit cost is the actual machining time per part plus material, plus a thin margin. Per-unit time depends on geometry: a simple aluminium bracket might cycle in 8-12 minutes; a complex 5-axis stainless part might cycle in 90 minutes.

Hourly rates in Ireland

The fully-loaded hourly rate Irish CNC shops charge in 2026 falls in these bands:

3-axis CNC milling: €60-95 / hour
CNC turning (lathe): €50-85 / hour
4-axis or 5-axis CNC milling: €95-150 / hour
EDM / wire-EDM: €120-200 / hour
CMM inspection (when called out): €70-110 / hour

Higher rates correspond to larger, multinational-supplying shops with ISO 13485 (medical) or AS9100 (aerospace) certification. Lower rates correspond to smaller family shops with ISO 9001 or no formal certification. Quality at the lower end can be excellent; the difference is mostly paperwork, traceability, and capacity, not skill.

A worked example — 10-part aluminium bracket

Let's price a typical startup-stage prototype: an aluminium 6061 bracket, 80mm × 120mm × 15mm thick, with a few pockets, four mounting holes, and a milled logo recess. Standard ±0.1mm tolerance. Run of 10 parts.

Setup

Roughly 3 hours of programmer + machinist time at a blended €75/hour. ≈ €225.

Material

Aluminium 6061 plate at €5-8/kg. Each part finishes ~0.4kg with 60% material removed, so raw stock is ~1kg/part. 10 parts × 1kg × €7 = €70.

Per-unit machining

Cycle time ~12 minutes/part on a 3-axis mill. 10 × 12min = 120min = 2 hours machining at €75/hour = €150.

Inspection & finishing

Standard deburr, no anodising, no special inspection. ≈ €50 flat.

Margin and overhead

Most Irish shops apply a 15-25% margin on top. ≈ €100.

Total

~ €595, or ~€60 per part. A real quote will probably land between €450 and €900 depending on the shop, complexity tolerance, and whether the shop has spare capacity that week. Anodising, plating, or a tighter tolerance can easily double this. A 5-axis equivalent (if your geometry forces it) lands in €1,200-2,000 territory for the same 10 parts.

Why your 2nd unit is cheap and your 2nd batch is dearer

This is the counter-intuitive bit that catches startups out.

Within a single batch, the marginal cost of additional units is small because setup is already paid for. Going from 10 parts to 20 parts in the same run might cost €595 → €750 — only €15/extra part instead of €60. This is why "order more while we have it set up" is genuine advice, not upsell.

But a separate second batch — months later — pays setup again. The shop has cleared the fixture, lost the CAM project file (or at least has to re-locate and re-validate it), and the machinist has to re-zero everything. So a second 10-part order placed three months later costs roughly the same as the first: €450-900, not €150. This catches founders who assumed the per-unit price was the price.

If you're going to need more parts in 6 months, tell the shop now. They can sometimes hold the fixture and the program in their archive, which cuts the second-batch setup by 50-70%.

Irish shop vs international quote platform

For startup-stage prototyping in Ireland, the two paths are genuinely different.

Use an Irish shop when…

You need to physically inspect a part, drop in to discuss it, or revise on the fly.
Your project will likely scale and you want to build a relationship.
You need certification paperwork (ISO 9001 minimum) for medical, aviation, or pharma.
Your part is unusual enough that DfM advice will come back ("this won't work — try this instead") — Irish shops are good at that conversation.
Lead time is 5-15 days and you can wait.

Use a quote platform (Hubs, Geomiq, partZpro) when…

You need a price anchor in the next 30 minutes for a board meeting.
The part is generic enough that DfM commentary won't matter much.
Lead time matters less than upfront cost transparency.
You're testing supply-chain economics — multiple quotes from different countries to benchmark.

The two paths are not in conflict. Plenty of Irish startups use a platform for the first prototype (because it's fast and the price is on the screen instantly) and an Irish shop from the second iteration onwards (because the relationship pays off). See the supplier directory for both options.

Hidden costs to budget for

Material certificates — typically free for standard alloys, €15-30/cert for traceable batches.
Anodising / surface finishing — adds 20-50% on aluminium parts; outsourced to a finishing house, adds 3-7 days lead time.
First Article Inspection (FAI) — usually €100-250 for the formal report. Required in regulated industries.
Shipping & courier — €15-40 anywhere in Ireland; international varies.
Revisions after delivery — almost always cheaper to budget a 2nd small run rather than re-machine the original parts.
