Precision machining as the basis for repeatable high-tech production
Precision machining
Our production capabilities
Precision machining forms an important foundation for the production of high-tech components, modules and systems. With 3-axis and 5-axis CNC milling, turning, multi-task machining, EDM and grinding, we produce parts with high dimensional accuracy and repeatable quality. Not only to make parts accurately, but to make designs suitable for stable series production. Engineering, workholding, tolerances and material behaviour are all considered as part of the process.
Through the close connection between engineering and production, we realise components that are not only functionally correct, but can also be produced repeatably and at scale.
We produce, among others:
- Precision mechanical components
- Precision parts for modules and systems
- Tooling components
- Parts with complex geometries
- Components in small to medium-sized series
Where quality begins
Our techniques for precision machining
3-axis CNC milling
3-axis milling provides a stable basis for producing accurate components with high dimensional accuracy. This machining method is used for parts that are less complex in shape, but where reliable workholding and repeatable tolerances are important within the wider production process.
The Okuma MB80 is equipped with its own pallet automation, allowing workpieces to be changed automatically and production planning to be arranged flexibly. This enables the machine to be used efficiently for longer unmanned production runs and series production.
5-axis CNC milling
With 5-axis milling, we produce complex geometries with high positioning accuracy and fewer workholding changes. This helps keep tolerance stack-ups under control and allows parts to be further prepared for assembly or follow-up processes in a single machining step.
Our two Fehlmann Versa 645 milling machines are connected to a Fanuc robot cell, which is linked to central storage via an AGV. In addition, our Okuma M560V and Yasda PX30i each have their own automation. These configurations make it possible to process parts within a continuous and partly unmanned production environment.
CNC turning
With CNC turning, we produce accurate round and cylindrical parts, such as shafts, bushes and rings. This process is suitable for components where dimensional accuracy, roundness and repeatability are important.
The turning processes are set up for integration into multi-step production routes and connect directly to follow-up processes within the production flow.
Multi-task machining
Multi-task machining combines turning and milling operations within one setup. This helps keep tolerance stack-ups under control and allows parts to be finished further towards the final component within a single machining cycle. It contributes to stable quality and efficient flow within series production.
Both NTX2000 multi-task machines are equipped with Fanuc automation for product handling, allowing parts to be processed automatically within longer production runs while remaining integrated into the overall production process.
EDM
With wire EDM, sinker EDM and EDM drilling, we realise geometries and tolerances that cannot be achieved with conventional machining. These techniques are used for sharp internal contours, complex mould details, start holes for wire EDM and operations in hardened or difficult-to-machine materials. This makes EDM an essential part of precisely built production routes for precision mechanical components and tooling.
One of our wire EDM machines is connected to the central automation, allowing this operation to become part of multi-step production without manual transfer between processes. Automated quality measurements can also be carried out within this chain, contributing to a stable and repeatable process.
Grinding
Grinding is used when fit, flatness and surface quality determine the functionality of a component within a module or system. This operation is often the final step within a tolerance chain where micron-level accuracy is required.
Grinding operations connect directly to earlier machining steps within the overall production process and contribute to a stable and repeatable final quality.
Efficiency in machining
Automated machining as part of an integrated production flow
Our machining centres are connected to the central automation within the factory and function as part of a continuous production flow. This allows us to produce complex high-tech components, modules and systems in a stable way, both as one-offs and in scalable series.
Through this integration, we are strong in products that consist of multiple machining steps and different process transitions. Automation supports a stable material flow, controlled tolerance stack-ups and a consistent quality level throughout the full route from component to final product.

Frequently asked questions
Practical questions and answers
Which machining techniques does Doeko offer?
Doeko offers various machining techniques, including 3-axis milling, 5-axis milling, CNC turning, multi-task machining, wire EDM, sinker EDM, EDM drilling and grinding. These techniques can be used separately or combined for high-tech components with multiple process steps.
To what accuracy can Doeko machine parts?
Doeko specialises in precision machining for parts with strict tolerances. The exact achievable accuracy depends on the material, geometry, workholding, production route and measurement method. For critical components, we assess in advance which tolerances are achievable and how we can secure them with repeatable quality.
Can Doeko produce products that require multiple machining operations?
Yes. Doeko is strong in products that require multiple machining operations, such as milling, turning, EDM, grinding and in-process inspection. By combining extensive knowledge and multiple techniques in-house, complex components can move through several process steps in a controlled way.
Can Doeko provide precision machining for one-offs and series?
Yes. Doeko provides precision machining for one-offs, small series and series production. The focus is primarily on products that ultimately need to be produced repeatably. A project often starts with one-offs or prototypes, after which the process is set up for stable series production.
