Wire EDM cutting of metals
Wire EDM cutting for highly complex and precise parts from a wide range of metals. The ideal solution when conventional machining is not possible.
Technical information
Wire EDM cutting examples
EDM cutting comes in where milling and turning have nothing left to offer. A hardened part that no cutter can touch. An internal corner a mill cannot reach. A wall so thin that cutting forces would simply twist it. In all these cases the wire works without contact – the metal is removed by an electrical spark, so the part is subjected to no mechanical load.
That is exactly why EDM is indispensable for dies, moulds and gears – parts that are already hardened and cannot risk deformation. It is often the last and most expensive production step, when all the previous work is already built into the material. We are based in Kaunas, so you can bring such parts in yourself and discuss them on site.
How do we handle orders?
Enquiry
We carefully review the 2D drawings, 3D models and technical specifications you provide, and assess the part geometry and material properties.
Quotation
We agree on the manufacturing technology, tolerances, quantities and lead times, and provide an accurate quotation. Once the order is confirmed, the project goes straight into our production schedule. If needed, we also arrange additional services (heat treatment, anodising, galvanising, etc.).
Production
We manufacture using modern equipment. To ensure full compliance with the technical requirements, we carry out strict measurement and quality control both during and after machining.
Logistics
We pack products securely to protect surfaces from damage and deliver them to the agreed address on time.
How to submit an enquiry
The more precise your enquiry, the faster you get a price. A drawing and the quantity are usually enough, but if you have more information, send it straight away – it saves extra questions.
File formats
Useful to include
We treat drawings and technical information as confidential – we do not share them with third parties or use them for other orders.
Materials used in manufacturing
We use only high-quality, certified materials. Taking into account your project requirements, operating conditions and loads, we help you choose the optimal material.
Frequently asked questions
Wire EDM (electrical discharge machining) is an innovative, highly precise metalworking method that uses electrical discharges to create the required shape. This advanced technology can machine even the hardest or hardened metals, producing complex geometries with micron-level accuracy that cannot be made by conventional milling or turning.
Unlike conventional CNC milling and turning, EDM is a non-contact process – the workpiece is machined by electrical sparks. With no mechanical contact, the part suffers no mechanical deformation, so EDM can cut extremely thin, complex and precise structures. EDM is ideal for sharp internal corners, narrow slots, dies and moulds.
We provide wire EDM cutting services from our production base in Kaunas – for customers in Lithuania and across Europe.
Wire EDM works by generating an electrical discharge between a wire electrode and the workpiece. With the workpiece held in a fixed position, the moving wire guides the cut and creates a spark next to the grounded part. The high voltage between the electrode and the part produces a spark discharge that locally melts the metal.
These discharges gradually remove material from the workpiece, forming the exact geometry of the part. Because the wire never touches the part, there is no cutting force – and therefore no deformation caused by it.
Three situations where EDM is usually the only way:
If the part is simple, not hardened and has no complex internal contours, milling will be faster and cheaper. Not sure which method suits your case? Send us the drawing and we will tell you.
