Micro Wire EDM – Maximum Precision for the Finest Components
Are you looking for a
specialist in
micro-wire EDM,
fine-wire EDM,
or high-precision
wire EDM?
Using micro wire EDM (micro-wire electrical discharge machining), we produce the finest contours, the smallest internal radii, and high-precision microcomponents from virtually any electrically conductive material. Where conventional wire EDM reaches its limits, our expertise begins.
As a Swiss specialist in micro-EDM, we support companies in the medical technology, precision mechanics, sensor technology, and watchmaking industries, as well as in tool and mold making—from feasibility studies through to series production.
Retero GmbH specialises in the micro-machining of high-precision metal components. With over 20 years’ experience, we manufacture components with tolerances in the micrometre range for demanding sectors such as medical technology, the watchmaking industry and precision engineering.
Thanks to fine-wire-erosion (micro-EDM), we machine metals of any hardness with the utmost precision, enabling us to bring even the most demanding projects to fruition. Swiss precision, cutting-edge technology and uncompromising quality make Retero a reliable partner for high-end applications.
Our commitment to quality is confirmed by our ISO 9001 and ISO 13485 (medical devices) certifications.
When is micro-wire EDM
the better choice?
Conventional wire EDM delivers excellent results for standard components. However, as soon as microgeometries, extremely fine webs, or the highest precision are required, the wire itself becomes the limiting factor.
Micro-wire EDM is particularly well-suited for:
- Microcomponents with extremely fine contours
- Inner radii starting at 0.02 mm
- Tolerances up to ±0.001 mm
- Delicate decorative inlays
- Precision Medical Components
- Microtools
- Microelectronics and Sensor Technology
- Complex components with very small webs and cutouts

Why Retero?
Many companies offer wire EDM.
We specialize in micro-wire EDM.
Machining with fine wires as thin as 0.02 mm is one of the most challenging aspects of electrical discharge machining. It requires specialized machines, many years of experience, and a deep understanding of high-precision microfabrication.
With over 20 years of experience in micro-erosion, we manufacture components that meet the highest standards in terms of precision, surface quality, and repeatability.
We process
virtually all electrically conductive
materials, including:
- Carbide
- Titanium
- Surgical-grade stainless steel (316L, 304)
- Tool steel
- Hardened steels over 60 HRC
- HSS
- Nitinol
- Hastelloy
- Aluminium
- Copper
- Brass
- Bronze
Typical Applications
- Microsurgical instruments for medical technology, such as forceps used in ophthalmology or biopsy forceps
- Implant components made of titanium, nitinol, and surgical steel
- Micro-punches, micro-dies, and precision tools for stamping dies
- Mold inserts for micro-injection molding and micro-stamping dies
- Precision parts for the watch industry, such as micro gears and escape wheels
- Sensor components, optical apertures, and components for microelectronics
- Microfluidic components, microchannels, and parts for research and development or for the aerospace industry
- Delicate precision components made of cemented carbide, tool steel, and special alloys
