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.
Caractéristiques Clés et Avantages
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.

Finitions de Surface en Usinage par Décharge Électrique
Nous proposons des finitions pour l'esthétique et la performance : anodisation, polissage, sablage, revêtements et traitement thermique. Trouvons celle qui convient !
Tel que usiné
Cette finition usinée est rugueuse et présente des marques d'outils, représentant la forme la plus basique de traitement de surface sans finition ni polissage supplémentaires.
Anodisation
"Il crée une couche d'oxyde protectrice sur l'aluminium, augmentant la résistance à la corrosion et la dureté, et permettant la teinture pour améliorer l'apparence."
Polissage
"Le polissage lisse les surfaces à un haut éclat, améliorant l'apparence et réduisant la rugosité tout en offrant une certaine protection contre la corrosion."
Finition Brossée
"Une finition brossée présente de fines lignes parallèles pour un aspect texturé, améliorant la prise et réduisant les empreintes digitales."
Sablage
Le sablage utilise de l'air à haute pression et des particules abrasives pour nettoyer ou texturer les surfaces, améliorant l'adhérence des revêtements.
Électropolissage
L'électropolissage est un processus électrochimique qui lisse et éclaircit les surfaces métalliques, éliminant les imperfections et améliorant la résistance à la corrosion.
