Eroding machines EDM

175 Machines
Electrical discharge machines (EDM) represent an advanced technology in the metalworking sector, used to remove metallic material through electrical discharges instead of physical contact with cutting tools. On Makinate, you will find a wide selection of used sinker EDM and wire EDM machines from leading brands such as Charmilles, Fanuc, Sodick, Ona, Agie, and Mitsubishi, specialized equipment for ultra-precision machining.

Characteristics of EDM Machines

EDM processes are used exclusively in the metalworking industry, as this technology can only be applied to electrically conductive materials.... Unlike conventional machine tools, EDM does not remove material by direct contact between a cutting tool and the workpiece. Instead, removal occurs through the erosive effect of controlled electrical discharges.The material removal process results from a combination of thermal and electrical effects. A conductive material can be eroded when subjected to a series of extremely short electrical discharges, each lasting only a few milliseconds. There is no physical contact between the electrode and the workpiece, which is a defining characteristic of this technology.EDM allows extremely precise machining and is particularly suitable for small and medium-sized components with high geometric complexity. Components produced with EDM usually do not require additional grinding or finishing, as the cut produced is extremely accurate and free of imperfections.

Sinker EDM Machines

Sinker EDM machines differ from wire EDM machines in that both the workpiece and the tool, which is an electrode, are immersed in a dielectric fluid. A series of electrical discharges between the electrode and the workpiece causes material erosion.

Negative Form Machining

The final shape of the workpiece is obtained as a negative replica of the electrode. The machine therefore shapes the metal by means of a three-dimensional male electrode. This process occurs in two phases:
  • First phase: creation of the electrode in the negative shape
  • Second phase: machining of the workpiece using the previously prepared negative electrode

Advantages of Sinker EDM

EDM is highly appreciated in the metalworking industry because it allows both hard and soft metals to be machined with great precision. At the same time, complex shapes can be produced without requiring further machining on other equipment.

Wire EDM Machines

Wire EDM machines use a thin copper or brass wire as the electrode. The wire acts as a cutting tool, moving vertically while progressing through the workpiece.The desired shape is stored in the machine by entering the machining program. The machine then automatically guides the wire along the programmed path to obtain the required shape with high precision.Wire EDM technology was developed later than sinker EDM, but it quickly became very popular due to its ability to produce highly precise and complex profiles.

Applications and Advantages of EDM

There are essentially two types of EDM: sinker EDM and wire EDM. Both technologies offer specific advantages for different industrial applications:
  • Extreme precision: ultra-precision machining without the need for secondary finishing
  • Complex shapes: creation of geometries impossible with traditional machining
  • Material versatility: capable of machining both hard and soft metals
  • No physical contact: no mechanical stress on the workpiece during machining
  • Excellent surface quality: smooth finishes free of imperfections

Application Sectors

EDM machines are used in various industrial sectors where precision and complexity are essential:
  • Mold and die making: production of molds and dies with complex geometries
  • Aerospace: precision components with tight tolerances
  • Medical industry: surgical instruments and high-precision devices
  • Electronics: miniaturized components
  • Automotive: complex parts for engines and transmissions
