Electric Discharge Machining (EDM): High-Precision Machining for Hard Materials
What Is EDM?
Electric Discharge Machining (EDM) is an advanced manufacturing process that removes material from electrically conductive workpieces using controlled electrical discharges (sparks). Unlike conventional cutting, EDM does not rely on mechanical force, allowing precise machining of extremely hard materials, intricate shapes, fine cavities, and complex geometries. EDM is commonly used in aerospace, automotive, mold making, tool and die, and medical industries where precision, surface quality, and tight tolerances are critical.
Características Clave y Ventajas
High-Precision Material Removal – Capable of tolerances as tight as ±0.01 mm for intricate components.
Works with Hard & Conductive Materials – Ideal for tool steels, titanium alloys, tungsten carbide, and exotic metals.
Complex Geometries – Produces deep cavities, narrow slots, sharp corners, and fine holes down to 0.1 mm diameter.
Two Main EDM Methods:
Sinker EDM – Uses electrode tools to create cavities, pockets, and detailed features.
Wire EDM – Uses a thin wire (0.02–0.3 mm) to cut precise contours and profiles.
Excellent Surface Finish – Surface roughness Ra 0.4–1.6 μm achievable with minimal post-processing.
Non-Contact Process – Reduces mechanical stress, distortion, and tool wear.

Acabados Superficiales de Mecanizado por Descarga Eléctrica
Proporcionamos acabados para estética y rendimiento: anodizado, pulido, chorro de arena, revestimientos y tratamiento térmico. ¡Encontremos el adecuado!
Mecanizado
Este acabado mecanizado es áspero y presenta marcas de herramientas, lo que representa la forma más básica de tratamiento superficial sin ningún acabado o pulido adicional.
Anodizado
Crea una capa protectora de óxido sobre el aluminio que aumenta la resistencia a la corrosión y la dureza, y permite teñirlo para mejorar su aspecto.
Pulido
El pulido alisa las superficies hasta que adquieren un brillo intenso, mejorando el aspecto y reduciendo la rugosidad, al tiempo que ofrece cierta protección contra la corrosión.
Acabado cepillado
El acabado cepillado presenta líneas finas y paralelas que le confieren un aspecto texturizado, mejorando el agarre y reduciendo las huellas dactilares.
Chorro de arena
El chorro de arena utiliza aire a alta presión y partículas abrasivas para limpiar o texturizar superficies, mejorando la adherencia de los revestimientos.
Electropulido
El electropulido es un proceso electroquímico que alisa y abrillanta las superficies metálicas, eliminando imperfecciones y mejorando la resistencia a la corrosión.
