Types of Electrical Discharge Machines
Sinker Electrical Discharge Machining
Sinker EDM is ideal in applications with stringent surface finish requirements, especially when cutting exotic or tough materials. It is widely employed in the injection molding and die-casting tool-making sectors. It is used to make nonmachinable complexity and finely detailed cavity features in molds without imposing any machining or impact stress on the mold.Tolerance range:±0.002
Surface roughness: Ra0.2
Workpiece size: 200*300*400mm
Wire EDM
Wire EDM, otherwise known as wire erosion, It is most commonly used for making extrusion tools and punch/die sets.Tolerance range:±0.002
Surface roughness: Ra0.2
Workpiece size: 200*400*550mm
Hole Drilling Electrical Discharge Machining
The hole-drilling EDM process is used to drill holes. It is especially useful for machining extremely small and deep holes, eliminating the need for deburring.Tolerance range:±0.02
Surface roughness: Ra0.8
Workpiece size: 200*300*400mm

Advantages of EDM Machining
Tight Tolerance
EDM offers exceptional profile accuracy, with tolerances as tight as ±0.005 in easily obtainable..
Flexibility
EDM can create shapes and contours that other types of machines cannot.
Materials
EDM can be used on any conductive material, whether it has been hardened or not, including stainless steel, titanium, tungsten, copper, carbide, and tool steels.
Distortion
EDM is suitable for cutting hardened materials. Forms can be machined after heat treating is complete, eliminating the problem of distortion caused by heat treat.
Precision
EDM is a precision machining process with no cutting force applied to the workpiece. It allows producing finely detailed parts that would be impossible to achieve with conventional cutting methods.
Finishing
The surface of a piece machined with EDM can be as smooth and consistent as 4Ra without polishing, eliminating the need for secondary operations in many applications.
