Welcome to EDM Extreme

  An EDM (Electrical Discharge Machining) machine, also known as a spark machining tool, uses electricity to cut or shape conductive materials by creating sparks between an electrode and the workpiece, removing material through a process of erosion. 

Here's a more detailed explanation:
  How it works: EDM machines use a rapid sequence of electrical discharges (sparks) between an electrode (tool) and the workpiece, which are both submerged in a dielectric fluid. These sparks erode the workpiece, removing small amounts of material at a time. The dielectric fluid helps to flush away the molten and vaporized material, and also acts as an insulator until the voltage is high enough to create a spark. The temperature of the sparks can range between 14,500 and 21,500 °F. 

Types of EDM:
    Wire EDM: Uses a thin wire as the electrode to cut complex shapes, often used for intricate parts and molds. Sinker EDM: Uses a shaped electrode to create cavities and complex shapes in hardened materials. Fast Hole Drilling EDM: Uses a rotating tube electrode to create deep, accurate holes quickly. 

Advantages of EDM:
  High precision: EDM can produce very accurate and complex shapes, even on hardened materials. No direct contact: The process does not involve physical contact between the tool and the workpiece, which can be beneficial for delicate or sensitive materials. Versatile: EDM can machine a wide variety of electrically conductive materials, including hardened steel, titanium, and tungsten carbide. 

Applications of EDM:
  Mold and die making: EDM is widely used for creating molds for plastic injection molding and metal die casting. Aerospace: Used for creating cooling holes in turbine blades and other complex components. Micro-hole drilling: EDM is well-suited for drilling small, precise holes. Prototype manufacturing: EDM is used for producing small parts and prototypes.
