What is EDM (Electronic Discharging Machining)
Electrical Discharge Machining (EDM) is a precision manufacturing process where electrical discharges shape hard materials. There are three main types: Wire EDM for detailed cuts, Sinker EDM for molds and cavities, and Hole Drilling EDM for making precise holes. Ideal for materials like hardened steel and tungsten carbide, EDM is crucial in the aerospace, automotive, and medical industries. Its key advantage lies in its ability to maintain material integrity, making it perfect for complex designs.
EDM stands out in precision engineering for its exceptional accuracy, versatility in materials, and capability to produce complex geometries, making it a vital tool in modern manufacturing sectors.
