Built for
Precision
Metamex Engineering delivers precision CNC machining services across the UK — CNC Turning, CNC Milling, Fibre Laser Cutting and CAD Design for aerospace, automotive, marine and beyond. Tight tolerances, fast turnaround, and British-made quality on every component.
Our Services
CNC Turning
Precision CNC turning in mild steel, tool steel and hardened steel to tight tolerances. From single prototypes through to high-volume production runs, we machine components to your exact specifications.
CNC Milling
Multi-axis CNC milling across a wide range of metals — if we can source the billet, we can machine it. Ideal for complex geometries, close-tolerance features and bespoke component work.
Fiber Laser Cutting
High-precision fibre laser cutting in mild steel, stainless steel, aluminium and brass. Material thicknesses from sheet up to 16mm depending on specification, with clean edges and fast lead times.
CAD Design
From rough idea to production-ready technical drawing using Autodesk Fusion 360. Ideal for clients who know what they need but don't have the drawings to make it happen.
Engineering the Future,
One Component at a Time
Metamex Engineering is a UK precision CNC machining company delivering custom-engineered components for aerospace, automotive, marine, construction, HVAC and more. Part of the Excell Engineering Group, Metamex was established as a dedicated precision machining division — bringing CNC turning, milling and fibre laser cutting in-house as part of a £250,000 expansion investment.
Based in Portsmouth and serving clients across the UK, we combine the backing of an established engineering group with the focus and responsiveness of a specialist precision machining company. Over 3,800 projects delivered. Every one made in Britain. View all our services.

Trusted Across Sectors
Our precision CNC machining services supply components to a broad range of industries across the UK. If your sector isn’t listed, get in touch — if it needs a precision-engineered component, we can almost certainly help.
Our Capabilities
Rapid Turnaround
Fast lead times without compromising on quality. We schedule precision CNC machining work efficiently to keep your supply chain moving, whether you need a one-off prototype or a repeat production batch.
Precision Engineering
Tolerances vary by process — from 0.5mm on laser-cut profiles through to 1.5mm on turned and milled components where design allows. State-of-the-art CNC machinery delivers consistent, repeatable results across every material and batch size.
Quality Assured
Every component leaves our Portsmouth facility having passed rigorous inspection. As part of the Excell Engineering Group — which carries the Made in Britain mark — we hold ourselves to the standards that British precision manufacturing is known for.
I'm immensely proud of what they've done here… I'm very proud that this company calls Portsmouth home.
