What CNC machined parts do we supply?

We supply precision CNC turned and milled components made to your drawing — housings, flanges, shafts, brackets, bushes, probes, fittings and fully machined assemblies. Send STEP, IGES, DWG, DXF or PDF; we handle everything from raw material to certified finished part.

  • CNC milling — 3- and multi-axis machining of prismatic parts and complex features
  • Materials — 316/304 stainless, aluminium alloys, brass, copper, mild & tool steels, engineering plastics
  • Finishing coordinated in — anodising, plating, heat treatment or polishing delivered as one finished part

How much do CNC machined parts cost in the UK?

Unit price is driven by material, tolerances, complexity — and above all, quantity. Setup and tooling are amortised across the batch, so unit prices fall steeply with volume. A part that costs £165 each as a 35-off qualification run can drop below £10 at 1,000-off.

That's why we quote first-article + production packages: qualify with a small batch at one rate, with a committed production price for volume already locked in. And once we've shipped a part, our 12-month price lock means you reorder at the same price — no quiet increases.

Every quote is itemised and comes back within 48 hours, with a free DFM review that flags anything in the drawing that would add unnecessary cost.

Why buy through TrueNorth instead of direct from a machine shop?

Because a machine shop gives you machining — and leaves you to manage material sourcing, finishing, certification, packaging and delivery yourself. We manage the whole chain and hand you one finished, certified part.

Your work goes to the vetted, ISO-certified partner best matched to each job — the right machine, the right rate — while you deal with exactly one person, accountable end-to-end. If anything ships wrong, we remake it at our cost. That's the deal, in writing.

CNC Machining — Common Questions

Straight answers, before you ask.

One. We quote single prototypes through to 10,000+ batch production. For qualification work, ask about first-article + production packages — a small batch at one rate with a committed volume price locked in.

ISO 2768-m/f as standard, to ±0.01 mm where the drawing requires it, with fine surface finishes (Ra 0.8 and better) available. The free DFM review flags any tolerance that would add cost without adding function.

No — and that's deliberate. We place your work with vetted, ISO 9001:2015 certified CNC partners matched to each job, then manage machining, finishing, certification and delivery as one accountable supplier. You get the right machine for every part, without managing multiple shops.

3 weeks standard from drawing approval to delivery; rush to 1 week on most jobs. Quotes with a free DFM review come back within 48 hours — within 4 if you flag it urgent.

Yes. A mutual NDA is standard — signed before we review your drawings, and your files are never shared beyond the supplier producing the part.
