Highest Precision – Zero Margin for Error
In the defence sector, surface quality determines functionality, reliability and safety. In few other industries are the demands on precision, surface finish, production efficiency and process stability as high. That is exactly why our OTEC machines and processes are designed for this.
We achieve surface roughness values down to 0.01 Ra – reproducible in series production and economically viable. This applies regardless of the material, size, geometry and batch size of your components. We find the right solution for every application.
Surface Finishing for Firearms
Application examples:Slide, Frame, Cylinder, Bolt Assemblies, Internal Mechanism, Barrel, Handguard, Lower Receiver, Magazine
Precision That Determines Function
Every detail counts in firearms: the failure of a single component renders the weapon inoperable – absolute precision is non-negotiable. Burrs and sharp edges on guides, bolt assemblies or magazine areas compromise reliability in the field. This is precisely where OTEC systems deliver: accurate deburring, consistent edge radiusing and a high-quality surface finish – for flawless function throughout the entire service life of the firearm.
Greater Efficiency in a Single Process
A single OTEC process replaces not only deburring, edge radiusing and finishing, but frequently also upstream and downstream steps such as shot blasting. This increases output and reduces unit costs. As the machines operate largely automated, 24/7 operation with minimal staffing is possible – for both bulk parts and individual components.
Optimal Preparation for Every Surface Treatment
After milling, surface preparation determines the quality of all subsequent processes. Our machines precisely reduce machining marks, micro-burrs and sharp edges without altering workpiece geometry. This creates a defined, reproducible base for diffusion and case hardening processes (nitriding, QPQ), conversion coatings (black oxide coating, phosphate coating) and optimum adhesion for DLC, PVD, nickel or ceramic coatings.
From Custom Workshops to High-Volume Production
Leading firearms manufacturers worldwide rely on our technology – from exclusive custom workshops to industrial high-volume production. OTEC processes combine the highest quality consistency with the most demanding precision requirements and clear cost advantages.
Precision Finishing for Ammunition
Application examples: Deep Drawing Punch, Cartridge Case, Projectile, Mirror Polish
Ammunition Quality: The Decisive Factor in Every Weapon System
The performance of a weapon system depends critically on the quality of its ammunition: even a high-performance system only delivers reliably when the ammunition is manufactured to the same standard of precision. Here, precision is not an option – it is a fundamental requirement.
High-Precision Machining Across the Entire Process
From optimising deep drawing punches to deburring, cleaning and polishing cartridge cases and projectiles, OTEC machines support ammunition manufacturing – reliably, automatable and cost-effectively.
Mirror Polish for Premium Positioning
In addition, OTEC machines polish ammunition cases and projectiles to a mirror finish in a fully automated process. This finish sets every round visibly apart from standard ammunition and underlines premium quality and brand value.
Deep Drawing Punches at a New Level of Precision
The finishing of deep drawing punches in particular pays dividends: reduced wear, higher drawing speeds, greater output and consistent quality. This is why ammunition manufacturers worldwide trust our processes.
Post-Processing for Additive Manufacturing
Application examples: Post-processing for 3D-printed defence components
Post-Processing as the Key Factor
Additive manufacturing has gained significant importance in the defence sector – from rapid prototyping and series components to tactical manufacturing containers deployed directly in conflict zones. But the quality of the final result depends critically on post-processing.
Mastering the Core Challenges of 3D Printing
3D printing introduces specific challenges: process complexity, automation requirements and frequently unsatisfactory surface structure. With OTEC solutions, you overcome these obstacles efficiently – a prerequisite for reliability and performance in the defence sector.
Efficiency Instead of Expensive Precision Printing
High-precision printing is expensive, slow and sensitive when tight tolerances are required. However, if a component is printed more economically by design, a downstream OTEC process brings it within the required tolerance in a fraction of the time and cost.

Drivetrain and Transmission Components for Military Vehicles
Application example: Drivetrain and transmission components
Same Components, Harder Requirements
Gears, shafts and bearing components are at the heart of military vehicles and tracked vehicles too – but built to a considerably more robust specification. Higher peak loads, extreme operating conditions and larger dimensions place exceptional demands on both components and surface finish.
Custom Solutions for Components of Any Dimension
Whether a compact gear or a large transmission component – our machines and processes are individually configured to match the size, geometry, material and batch size of your components. This enables even the heaviest military components to achieve the same precision and surface quality as automotive standard – from deburring and edge radiusing through to a surface finish that reduces friction and wear.

Aerospace
Application examples: Blades, Discs, Blisks, Seals (military)
Proven Experience for the Highest Demands
The demands placed on civil aerospace components such as blades, discs, blisks or seals are already exceptionally high. Military components, however, set the bar even higher – where absolute reliability and uncompromising peak performance are required and zero tolerance for error is accepted.
Proven Experience, Specialised Machines
Thanks to long-standing partnerships with international customers, we meet all requirements of the defense sector within aerospace – reliably and reproducibly. This is made possible by our machines developed specifically for aerospace applications: they accommodate even the most demanding specifications and deliver the highest surface quality and process reliability.

Your Partner for Perfect Surfaces
In our Finishing Centre, we process your components – or, on request, abstracted substitute components – and show you the achievable result for your specific application. You see the potential before you invest.
Note on Handling Defence Samples
Due to various national and supranational regulations, we follow an established due diligence and compliance process when handling defence samples. The receipt of samples from abroad generally requires prior approval from the relevant German authorities; this process is outside our control and may take time. As an alternative, we work with abstracted substitute components that do not represent the actual end product but demonstrate our process capabilities with regard to geometry, deburring and smoothing equally well.
