EDM Machining

What is EDM manufacturing?

Electrical discharge machining refers to a method of processing workpieces in a certain medium through the electrical erosion of pulse discharge between the tool electrode and the workpiece electrode. EDM manufacturing is a non-contact machining method used to cut unmachinable complex shapes and cavities in very hard, difficult-to-machine materials.

The types of EDM manufacturing:

1. Wire EDM
Wire-cut electrical discharge machining, often referred to as wire EDM, it uses a wire as a "cutter" to erode material through sparks between the wire and the workpiece.
2. Die-sinking EDM
Die-sinking EDM relies on custom-shaped electrodes to remove excess material from the workpiece.
3. hole-drilling EDM
Hole-drilling EDM was the first electrical discharge machining technology and remains a vital machining method in a variety of fields, including rocket engines, gas discharge control devices of medical and scientific equipment, as well as open cooling channels in gas turbine blades. It is commonly used for different types of holes, such as round holes, square holes, polygonal holes, special-shaped holes, etc.

Both types have unique advantages and are suitable for a variety of applications, depending on the specific requirements of the project when you need to choose one.

What is the purpose of using EDM?

EDM can replace traditional machining techniques for hard materials, especially for machining refractory metals and difficult-to-cut shapes. EDM can maintain high precision and very low Ra levels for each part. This feature reduces post-processing, often reducing the cost of difficult-to-manufacture components.

The main applications of EDM fabrication

1. Aerospace industry
EDM fabrication is widely used in the aerospace industry due to its ability to machine complex shapes and geometries in difficult-to-machine materials such as titanium, Inconel, nickel alloy, and high-strength steel alloys.
2. Medical device manufacturing industry
EDM fabrication can manufacture complex, high-precision components for the medical device manufacturing industry.
3. Automobile industry
EDM fabrication has many applications in the automotive industry to produce high-quality components that meet stringent performance and durability requirements. Common materials used in automotive applications include steel, aluminum, and specialty alloys.
4. Mould making
Mold-making is another industry where EDM fabrication plays an important role. This process is used to create high-precision molds for plastic injection molding, metal stamping, and die-casting operations. EDM's ability to machine hard materials and create complex shapes makes it ideal for producing these precision tools.
