CNC Machining Cost — What Actually Drives the Price
There is no single price for “a CNC part.” The same envelope can cost very differently depending on five levers. Here is what they are, why we quote per drawing, and how to get a number you can trust.
Why There Is No Flat CNC Price
A CNC quote is built from machine time, material, programming, fixturing and inspection — not a catalogue rate. Quoting a number before seeing the part would be a guess, and a guess either prices you out or hides cost that shows up later. So the honest answer to “how much is a CNC part” is “it depends on your drawing.”
The Five Levers That Drive Cost
| Lever | Lower cost end | Higher cost end |
|---|---|---|
| Material | Aluminium 6061, mild steel | Titanium, Inconel, PEEK |
| Geometry | Simple prism, turned shaft | Thin walls, deep pockets, 5-axis |
| Tolerance | Standard ±0.1 mm | Tight ±0.01 mm or finer |
| Quantity | 200–500 (setup spread) | 1–10 (setup per part) |
| Surface finish | As-machined | Anodise, plate, bead-blast |
How Quantity Changes the Per-Part Price
Every order carries setup — programming, fixturing, first-article checks. At one or ten pieces that setup sits on few parts, so the per-piece price is higher. From the low hundreds upward the setup is spread thin and the price drops. We do not pad the unit price just because the quantity is low; you simply see setup stated openly.
Why We Quote From Your Drawing
A real quote separates material, machine time and finishing so you can see where the money goes. Send a clean drawing with dimensions, tolerances and material, and you get a transparent number — usually within 24 hours. The browser-side instant quote tool gives a reference price without uploading files.
How to Get the Lowest Real Price
Relax tolerances that are not functionally critical, pick a common material (aluminium 6061 over exotics unless needed), keep the geometry fixturing-friendly, and send a clean drawing. Small changes here often cut more cost than chasing a cheaper shop. For first-time, low-quantity jobs this matters most — see our small orders page.
What We Never Do
No hidden fees, no penalty surcharge for small batches, no charge to get a quote. The number you see is the number we machine to.
