Metal Spinning in Defence: Not Just for Saucepans
When you think of metal spinning, images of gleaming kitchenware or decorative light fixtures might come to mind. But what if we told you this very same technique is behind some of the most crucial components safeguarding the UK's defence sector? In this blog, we aim to recalibrate the way you think about metal spinning, and the important role it plays in the defence industry. Yes, the very same manufacturing process used to make your favourite pans also crafts vital components for the UK’s Defence sector.
But what exactly is Metal Spinning? In short, it is the process in which a flat sheet metal disc is clamped to a Mold / Tool which is attached to the headstock of a lathe with a metal thread. The clamp, attached to the tailstock of the lathe, is positioned in place and clamps the discs against the tool. When the lathe is turned on, both the disc and tool spin at high speed (or rotations per minute – RPM). The operator, if performed by hand, will use a roller tool, and apply pressure to the disc. The metal disc will then form over the contour of the tool taking shape. When performed on a CNC, rather than the operator physically forming the material over the tool, a spinning wheel is programmed to do it instead, taking the labour out of the job. The result? An axially-symmetrical, seamless component.
Metal Spinning isn’t just for homeware, but also for the hard-hitting world of Defence. So, next time your admiring a beautifully spun bowl, remember – it’s a close cousin to that missile nose cone or radar dome protecting our nation.

Why Defence needs Metal Spinning: The Secret’s in the Spin
You might ask, “why is metal spinning key to the defence industry, especially over other methods?” The simple answer – strength, precision and flexibility. Spun metal components are inherently strong thanks to grain flow, which means it can handle the most demanding applications in defence.
Moreover, metal spinning allows for rapid prototyping and production of complex, symmetrical shapes with minimal waste. Need a custom part for a drone? Metal Spinners can deliver it faster than you can say “air superiority”. (Okay, that might be a slight exaggeration, but you get the point).
And let’s not forget the cost savings. With metal spinning, you get high-quality components at a fraction of the cost of forging or casting. And tooling is a fraction of the cost of press tools! Defence budgets everywhere can breathe a collective sigh of relief.
Metal Spinning vs. Other Processes: A Battle of Titans
Defence engineers love a good showdown. So, how does metal spinning shape up against traditional fabrication methods like casting, machining or forging?
For starters, metal spinning is more efficient on material usage. There’s less waste, which is great for budgets and the environment. Furthermore, metal spinning can achieve tight tolerances and smoother finishes in fewer steps.
While forging is fantastic for brute strength, and machining wins on fine detail, metal spinning is the all-rounder; strong, precise and quick. If defence was a football team, metal spinning would be the versatile midfielder – always where you need it most.
Spinning Up Innovation: CNC Metal Spinning in Defence
Gone are the days when metal spinning was just a craft passed down through generations. Today, CNC metal spinning is setting new standards in defence manufacturing. Computer-controlled lathes can shape metal with pinpoint accuracy, producing complex geometries that would make even the most seasoned engineer swoon.
What’s more, CNC spinning boosts repeatability, so every part meets exacting defence standards. Need a batch of high precision sensor housings for a fleet of surveillance drones? CNC spinning has your back.
This fusion of tradition and technology ensures defence components are stronger, lighter and more reliable than ever before.
Materials Matter: Aluminium, Steel, Copper and More
Not all materials are created equal – especially in defence. Aluminium is prized for its lightweight strength, making it perfect for aerospace and lightweight armour. Stainless steel offers corrosion resistance and toughness, ideal for land and naval defence components.
There’s more! Brass, copper and special alloys each have their moment in the defence spotlight, whether its for electromagnetic shielding or high-temperature applications.
With metal spinning, working with these materials is made easier, adapting quickly to new defence needs.
Quality Assurance: The Defence Industry’s Favourite Buzzword
In the world of defence, “good enough” just doesn’t cut it. That’s why ISO 9001:2015 quality management systems are more than just a plaque on the wall for leading UK metal spinners. Within Excell, we have some of the most rigorous inspection processes – up to 100% if the customer demands – which ensures that every spun part meets or exceeds military standards.
From initial drawings to final inspection, traceability and meticulous documentation are the order of the day. If a defect slips through, non-conformance reports and swift corrective action keep the supply chain ticking.
So, while metal spinning is an art, it’s one with a laser focus on quality and reliability. Something we have worked hard on over the last few decades and have developed a reputation for.
Defence Customers: Who’s Ordering All These Spun Parts?
It’s not just the MoD ringing up UK manufacturers. Defence contractors, aerospace OEMs, and even innovative start-ups working on next-gen military tech are all in on the action.
These clients demand rapid turnaround, flexibility in batch size, and airtight confidentiality – three things we “Excell” at. Non-disclosure agreements are standard fare with our service, along with our customer portal. This portal is giving our clients real time updates (think Domino’s Pizza tracker, but for spun components).
If you’re in the business of keeping Britain’s shores safe, chances are you’ve benefited from a spun metal component or two!
The Future of Metal Spinning in Defence: Lighter, Faster, Greener
Defence is ever evolving and constantly on the move, just like metal spinning. The next wave of innovation is all about lighter materials, faster production, and yes – even sustainability. Imagine high-strength alloys spun with minimal waste, or recycled materials forming the backbone of tomorrow’s defence kit.
Digital tracking, real-time order updates, and advanced CNC machines are some of the ways we are making processes even smarter. As the UK defence sector pushes for greener, leaner operations, expect metal spinning to lead the charge with eco-friendly practices and digital efficiency.
So, if you thought the ancient art of spinning was stuck in the past, think again. The best is yet to come!
