Top 8 EDM Machining Manufacturers In The World

Electrical Discharge Machining (EDM) is a non-traditional material removal process in which the material is eroded using electrical sparks. The edm precision technique involves a thin wire, generally brass, as an electrode of 3 mm diameter. It is dipped in a dielectric fluid such as water or oil and then polarized or charged electrically. When energized, the wire sparks and discharges at a high rate, removing the material of the wire from the wire. These sparks, which are within the fluid, melt and remove small particles from the workpiece to allow the formation of very fine and intricate shapes. This article highlights the services of top EDM manufacturers across several sectors.

Features of EDM Machining

Some of the most essential characteristics of the Electrical Discharge Machining (EDM) are as follows: 

• High Precision for Complex Shapes: Electrical Discharge Machining (EDM) is suitable for making complex shapes with high precision. This is done by employing ultra-fine wires and a programmed system to control the machining operation. For instance, where intricate parts like small gears are being manufactured, EDM can retain the required accuracy, for example, of a shaft hole, which may not be perfectly circular, or the tooth tip profile. Such tight tolerances are difficult to achieve using more conventional techniques such as cutting; however, with EDM’s fine wire, a part can be shaped to the finest details.  

• Ability to Machine Hard Material: EDM is optimal for machining high-strength materials that are difficult to machine through conventional means. It uses electrical discharges to remove material and is suitable for any conductive material, irrespective of its hardness. This is especially useful in manufacturing high-strength press dies where other cutting methods cannot be used. The fact that EDM can work with these complex materials and produce such accurate shapes is a significant plus in making solid, high-performance parts.  

• Non-Contact Machining: EDM machining does not require any tool to come into contact with the workpiece. This non-contact approach means that no outside pressure is applied to the material, and therefore no distortion occurs, and there is no need for further refining operations as may be required in burr removal or chamfering. It gives the characteristic of a clean, precise cut surface right from the EDM process without further polishing.
