Electrical discharge machines (EDM)

EDM machines include wire-cut (WEDM), sinker, and copy EDM models with CNC for non-contact machining of conductive materials. They are used in mold & die making, aerospace, medical device manufacturing, and precision engineering to produce complex shapes from hardened steel, titanium, and exotic alloys.

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.
