At ARMBRUSTER, we have stood for passion, precision, and reliability in component machining for over two decades. The combination of our expertise, skilled team, and state-of-the-art machine park makes us your trusted partner for sinker and wire EDM subcontracting.
Whether intricate EDM parts, complex geometries, or custom tooling – we manufacture your components with the highest precision, combining advanced technology with a deep understanding of your individual requirements. Our goal is not just to produce parts, but to deliver solutions that fulfil your technical and functional needs perfectly.
Wire EDM and sinker EDM are among the most advanced manufacturing methods in subcontracting – and they are key areas of expertise at ARMBRUSTER.
In Wire EDM, a thin wire is used as an electrode and guided precisely through the workpiece. This method enables us to produce highly accurate contours, delicate geometries, and even extremely complex components – ideal for toolmaking, mechanical engineering, and medical technology.
Sinker EDM uses a shaped electrode that sinks into the workpiece and removes material through spark erosion. This technique is especially suited for deep cavities, complex shapes, and demanding tooling applications.
At ARMBRUSTER, we combine both technologies – wire and sinker EDM – to offer you a comprehensive solution tailored to your requirements. Thanks to our expertise and cutting-edge machine park, we can implement individual customer specifications with precision – from single parts and prototypes to full series production.
We focus on quality, precision, and personal consultation to ensure the success of your project. We don’t just manufacture products – we deliver quality you can rely on.
The combination of sinker and wire EDM allows us to perfectly align with upstream processes, enabling even more efficient and faster production of your components. From complex geometries to demanding EDM parts – our CNC technology and expertise are your advantage.
For Wire EDM, we use state-of-the-art machines from Agie GF, equipped with palletising systems. With tilting units and specially developed fixtures, we can machine multiple angled contours in a single setup – ensuring maximum precision and efficiency.
In Sinker EDM, we rely on Sodick machines. Using a zero-point clamping system for both workpieces and electrodes, we enable external presetting on the coordinate measuring machine. The measurement data is transmitted directly to the EDM machine – speeding up the process and ensuring outstanding accuracy.
We offer tailored solutions for your components, regardless of order size – whether for single parts, prototypes, or series production.

Wire EDM (Electrical Discharge Machining), also known as wire erosion or wire cutting, is a high-precision manufacturing process in which a thin, electrically conductive wire removes material from a workpiece through spark erosion. This method is ideal for producing complex geometries, delicate components, and precision tools.
At ARMBRUSTER, we use wire EDM technology to meet demanding requirements in toolmaking, medical technology, and mechanical engineering.
Sinker EDM (Electrical Discharge Machining) is a precise manufacturing process based on spark erosion. A specially shaped electrode is used to remove material from a conductive workpiece through controlled electrical discharges. The electrode, shaped as the negative form of the desired part, is lowered into the workpiece. A small gap between the electrode and the workpiece allows targeted spark erosion to remove the material.
This process is especially suited for manufacturing tools, moulds, and complex components that are difficult or impossible to produce using conventional machining methods.
Wire EDM and sinker EDM are both electrical discharge machining (EDM) processes, but they differ in how they work and where they are applied.
Wire EDM uses a continuous, electrically conductive wire as an electrode to cut through the workpiece and create precise contours. In contrast, sinker EDM uses a solid, pre-shaped electrode that forms cavities in the workpiece by spark erosion.
At ARMBRUSTER, we operate CNC-controlled wire EDM machines with travel ranges up to X800, Y600, Z510 mm. Wire EDM is especially suitable for:
Sinker EDM is used when complex three-dimensional shapes or deep cavities are needed. A specially shaped electrode is lowered into the workpiece, and controlled spark discharges remove material. Its advantages include:
At ARMBRUSTER, we master both EDM technologies and combine them to deliver precise, custom solutions tailored to your product requirements.
Outsourcing wire EDM to a specialised contract manufacturer offers many advantages – especially if your business lacks the necessary equipment, capacity, or expertise.
1. Cost Savings
Investing in state-of-the-art wire EDM machines is costly. Maintenance, operator training, and operating expenses add further overhead. By outsourcing to an experienced contract manufacturer like ARMBRUSTER, you avoid these high costs and can focus on your core competencies.
