Understanding EDM Services
What Is EDM?
Electrical Discharge Machining (EDM) is a highly precise method used to cut or shape metals and conductive materials. Instead of using physical force, EDM employs electrical sparks to reshape materials—even the hardest alloys—without direct contact.
There are two primary types of EDM:
- Wire EDM: Uses a thin metal wire to cut through parts with extreme accuracy, ideal for detailed shapes.
- Sinker (or Plunge) EDM: Uses custom-shaped electrodes to create cavities or intricate features, especially useful for molds and dies.
Why Choose EDM?
EDM is popular because it offers:
- Extreme precision, even on hard or delicate materials
- Ability to create complex shapes not possible with traditional methods
- Smooth finishes that often require little post-processing
- Minimal workpiece stress (since there’s no cutting force)
EDM technology is widely used in industries like aerospace, automotive, electronics, mold-making, and medical device manufacturing.
