Electroerosion: Precise Work
The Electroerosion It is a machining technique that has transformed the manufacturing industry, allowing for precise and efficient work with difficult-to-cut materials. Below, we will explore the history of EDM and its various uses today.
History of EDM
The Electroerosion It was discovered accidentally in 1943 by Soviet scientists BR and NI Lazarenko. While researching methods to protect electrical contacts from erosion, they discovered that controlled electrical discharges could be used to cut and shape metallic materials with great precision. This discovery gave rise to a new machining technique that would revolutionise the manufacture of complex components.
Technological Evolution of Electroerosion
Since its discovery, the Electroerosion has experienced significant technological advances. In the early days, EDM machines were rudimentary and limited in terms of precision and control capacity. However, over time, the development of computer numerical control (CNC) systems allowed for millimetric precision and greater efficiency in the process.
In the 1970s, the introduction of the Wire EDM further expanded the capabilities of this technique. This method uses a conductive wire that moves continuously through the material, allowing for complex and detailed cuts that would not be possible with other machining methods.
Uses of Electroerosion
The Electroerosion It has become an essential tool in various industries thanks to its ability to work with hard materials and produce parts with high precision. Below are some of its most notable uses.
