Wire EDM
Wire erosion is a shaping cutting process that is used in the production of parts with particularly high tolerance requirements. In wire erosion, also known as spark erosion, a thin wire is used as an electrode to separate material from the workpiece very precisely. The dimensional accuracy of wire EDM is up to ± 0.002 mm. The maximum dimensions of the materials are 250 mm by 350 mm with a maximum height of 200 mm. Wire EDM enables the burr-free and taper-free production of workpieces with particularly high accuracy requirements.

Wire EDM achieves a particularly high level of precision, making it a popular manufacturing method. The process is frequently used in the manufacture of tools, punches and dies. DeSta::Microcut uses wire EDM for the production of special bending tools, enabling short delivery times.
DeSta::Microcut customers benefit from the advantages of this precise production technology without having to invest in expensive machines. By outsourcing to a specialist company, companies can save time and money. They can concentrate on their core competencies while the production of precise parts is in experienced hands. The high level of accuracy and the ability to machine even hard materials make wire EDM an attractive option.
What is wire erosion?
Wire EDM, also known as CNC wire EDM, is a shaping manufacturing process. It enables the cutting of conductive materials such as metal using electrical voltage pulses. A wire, usually made of brass or copper, is guided to the workpiece to be machined under electrical voltage. The workpiece is placed in a liquid dielectric containing deionized water. The acceleration of the electrically charged particles generates a visible spark that removes the material.
Wire EDM is used, for example, in the production of stamping tools and complex metal parts. The machining of precision parts for the aerospace industry and in medical technology are also among the areas of application. Due to its precision and versatility, wire EDM is suitable for the production of prototypes and small series.
In contrast to laser fineblanking, wire EDM works differently and is based on the controlled electrical discharge between the wire and the workpiece. This results in precise and fine cuts that also enable fine contours and complex geometries. This process is primarily used for conductive materials, regardless of their hardness. In addition, the process enables very small cutting widths even with high material thicknesses.

Which materials can be processed?
Wire EDM is a process that can be used for non-contact machining of a variety of conductive materials. These include hardened materials such as steel and titanium, but also softer materials such as aluminum and copper. By precisely controlling the wire EDM, complex shapes can be produced with high accuracy requirements. This is particularly advantageous in the production of tools and molds.
Wire EDM is also suitable for contract manufacturing, as it can process a wide range of materials and delivers very precise results. The areas of application for wire EDM are diverse and range from the production of individual components to the series production of parts.
Advantages and disadvantages of wire EDM
CNC wire EDM offers high dimensional accuracy and enables the machining of difficult-to-cut materials such as titanium alloys, hard materials or conductive ceramics. The excellent surface quality of the workpieces and the smallest corner radii are a further advantage of this manufacturing process. There is no contact between the workpiece and the coated wire.
However, the costs for wire EDM are comparatively high and the material properties can impose restrictions on the applicability of the process. Furthermore, the use of wire EDM is limited to certain areas of application.
Overall, wire EDM therefore offers some clear advantages in terms of shape accuracy, the machining of difficult-to-cut materials and the surface quality of the workpieces. However, the potentially high costs and the limitations in terms of material properties and areas of application must also be taken into account.

What is the difference between wire EDM and die-sinking EDM?
Wire EDM and die-sinking EDM differ in their processes, applications and machining methods. Wire EDM uses a thin wire as an electrode, which erodes complex shapes precisely using electrical discharge machining. This is used in the manufacture of precision components and tools. In contrast, die-sinking EDM plunges an electrode into the workpiece to erode hard material with an electric current. This is particularly suitable for deep, complex shapes in steel or carbide. Both processes have different applications, with wire EDM being suitable for thinner shapes and die-sinking EDM for deeper cavities and more complex workpieces. Both are crucial processes in modern manufacturing.
