EDM (electrical discharge machining, also known as spark eroding or wire erosion) is a machining process that uses the electrical discharges to alter the shape of a workpiece - an electrical current passes between an electrode and a workpiece which are separated by a dielectric liquid and as a result spark erodes the workpiece to form a desired final shape. 

 

Types of EDM machines:

  • Wire-cut EDM (WEDM);
  • Die-sink EDM (Ram-type EDM);
  • Hole drilling  EDM;

Combined with computer numeric controls (CNC), EDM machines become an accurate and reliable machining method that is now standard among more conventional cutting methods. It is particularly popular for small-volume productions such as prototypes. Various processes are possible with electrical discharge machining, including turning, milling, grinding and small hole drilling. Besides die and mould-making, EDM is typically applied in the automotive and aerospace industry, for example, in the production of aircraft engines.

 

Advantages:

  • Machining the hight hardness workpieces made from titanium or tungsten carbide;
  • Machining the shapes and depths what are impossible to process with a cutting tool;
  • Excellent surface finish;
  • High precision machining method

However, EDM machining is the rather slow method compared to traditional machining, therefore high-volume tasks are not suited for this method. At the same time, the spark eroding process requires high power consumption. If need to rough cut a lot of parts quickly, electrical discharge machining probably isn’t the right processing machine.
