High-precision CNC sinker EDM (Electrical Discharge Machining) industrial services
At Erosystem we operate with high-precision volumetric electro-erosion sinking (Sinker EDM) technology to manufacture and recover critical high value-added components for demanding sectors such as rail transport, automotive, aeronautics or the electronics and energy industries.
We offer expert and free technical advice on electroerosion processes and develop tailor-made solutions for volumetric geometries impossible to achieve by conventional methods, guaranteeing tolerances of up to ±10 µm and surface finishes below Ra 0.8 µm, under European quality and traceability standards.
We work with aluminum, copper, tempered steels up to 66 HRc and nickel-based superalloys, participating in international projects through the regular supply of electro-erosion processed parts to industrial clients in Spain, France and Germany.
Engineers from European TIER-1 / TIER-2 clients rely on our Sinker EDM processes
Precision sinker electrical discharge machining (Sinker EDM)
We perform centesimal volumetric electroerosion for blind internal cavities of complex geometry in conductive materials of high hardness, using copper or graphite electrodes manufactured specifically for each application.
Technical capabilities:
- Typical tolerances: up to ±10 µm.
- Surface finishes: Ra ≤ 0.8 µm.
- Cavities with inner radii of <10 µm.
- Microperforations and blind cavities <1 mm².
Like wire EDM and unlike conventional chip removal manufacturing methods, sinker EDM has the great advantage of being a neutral process that does not transmit mechanical stresses to the workpiece, maximizing the final accuracy and precision obtained.

Frequently Asked Questions
What kind of projects can Erosystem help me with?
Erosystem is an expert in developing comprehensive solutions in precision machining and electro-erosion for single parts, short series, and turnkey tooling.
We have a team of qualified engineers and advanced technology to design, manufacture, measure and assemble all types of mechanical components that require to be produced by means of precision machining, grinding and electro-erosion techniques.
Can I request a quote without having a technical drawing?
It depends. If you’re looking to have a specific, pre-designed component manufactured, we require a technical drawing or a 3D model showing all the specifications that must be met.
Conversely, if you have an idea, a sketch, or a physical sample, our engineers will review the details with you to offer a proposal tailored to your needs.
How long should I wait to receive a quote?
Depending on the complexity of the request. For the manufacture of specific components according to a drawing, you will normally receive a quote in less than 3 business days.
For poorly defined projects that require analysis and conceptual design, or complex projects where a wide variety of manufacturing processes, materials and treatments come into play, the bidding time is extended.
However, our sales team will be in constant contact with you to understand your needs and keep you informed while we prepare the optimal proposal for you.
What delivery times can I expect from the moment I place a formal order?
It will depend on the type of project, the complexity of the parts to be manufactured, and the quantities required.
In any case, we will use all available resources to meet the delivery milestones you require, and our sales team will advise you from the beginning so that you have a realistic expectation in this regard.
Do you provide technical support before subscribing to the service?
Yes. Our engineers are dedicated to understanding each application in order to advise you from the consultation phase, with the aim of resolving all the doubts you may have regarding precision machining processes, electrical discharge machining, and other aspects related to the project.
The goal is to define the optimal manufacturing process so that the economic proposal is as competitive as possible.
Do you perform machining of single or unique parts?
Yes. We are experts in the precision machining of single or unique parts according to the customer’s drawings.
Do you perform prototype machining?
Yes. We manufacture prototypes for technical validation in the early stages of development and assist you in the industrialization process with a functional, effective, efficient, ergonomic, and cost-effective approach. This service is ideal for clients who need to validate the component before mass production.
