Used Spark drilling machines (Small Hole EDM)

Start hole EDM machines are special EDM machines used for machining holes or bores in metals and alloys. These machines work with a wire that is guided through the material to be machined. The wire is controlled by a wire guide system and a feed system and moves in a zigzag motion to erode the material. Start-hole EDMs are especially useful for making holes or bores in hard-to-reach areas because the wire can be fed through the material. They are also very accurate and can produce holes with diameters as small as 0.2 mm or smaller. These machines are used in many industries, especially aerospace, automotive, medical and electronics. They are used to create starter holes for wire EDM machines or to drill fine holes in components such as turbine blades, fuel injectors or medical instruments.
