Defence Precision Engineering

Capabilities that de-risk your programme

In the UK and European defence sector, success depends on more than innovation, it relies on proven, reliable delivery. Defence programmes often involve complex assemblies, strict timelines, and the highest expectations for accuracy and traceability.

That’s where Defence Precision Engineering adds value. With advanced machining and robust quality processes, Milturn helps reduce risk across every stage of your programme.

Precision machining expertise

Our capability in 5-axis CNC and turn-mill machining allows us to deliver complex parts with confidence. These technologies reduce operations, improve consistency, and achieve accuracy where every micron matters.

We specialise in tight-tolerance machining, supporting customers from prototype to production. From land-based equipment to electronic warfare (EW) systems, countermeasures, and radar technologies, we deliver components designed for critical defence applications.

What sets us apart is our ability to help customers refine designs at the prototype stage. By identifying potential machining challenges early, we reduce the risk of costly changes later in the programme. This design-for-manufacture (DFM) approach shortens lead times and improves the likelihood of a smooth transition into full production.

Surface treatment options

Machining is only part of the solution. Components often need surface treatments to perform in harsh environments. We offer:

• SurTec 650 – a widely adopted, environmentally compliant treatment for defence.
• Anodising – for durability and corrosion resistance.
• Powder coating – for protection and appearance.

These finishing options ensure parts are ready for demanding, real-world conditions.

Quality and compliance

In defence, precision is more than machining – it’s about process, control, and documentation. Our Quality Management System (ISO 9001 and ISO 13485) underpins every project.

Key strengths include:

• Process control plans with in-process inspection.
• Full traceability, including lot traceability and Certificates of Conformance (CoC).
• Digital thread management, PPAP, FAI, GD&T and CMM inspection.
• Materials certified to ISO 10204, certificate 3.1.
• Compliance with UK and EU DEF STAN standards.

By November 2025, we also expect to hold Cyber Essentials certification, strengthening digital security and traceability for our customers.

Proven defence delivery

Milturn Precision has a strong track record of supporting urgent defence requirements. One example is the redesign of a communications component for the Ministry of Defence.

We managed the entire process in-house, from design through machining, assembly, and finishing. Despite an extremely tight timeline, the project was delivered ahead of schedule. This allowed the customer to meet critical operational needs without delay.

The success of this programme led to follow-on contracts and reinforced our reputation as a trusted defence precision engineering partner. It shows our ability to combine speed, quality, and reliability, the key factors that reduce risk in defence supply chains.

A partner that reduces risk

Defence programmes need suppliers who can be trusted to deliver right-first-time. A single delay or a non-conforming part can have a knock-on effect across the supply chain. That’s why we combine advanced machining, proven finishing processes, and rigorous quality control to ensure complete confidence in every component.

From early-stage prototypes to full production runs, Milturn provides the consistency, accuracy, and traceability that modern defence programmes demand. Our team is focused on building long-term partnerships, giving customers the assurance that critical parts will be delivered on time and to specification.
