Electrical Discharge Machining (EDM) is a non-traditional machining technology, two types of EDM are Wire Cutting WEDM and Electrical Discharge Machining (EDM), which is used in several manufacturing sectors to develop customised parts with extremely high precision and accuracy.
EDM uses thermal energy to separate material from the workpiece. Manufacturers turn to EDM when CNC milling and turning cannot provide the required cuts, such as deep cavities and sharp internal corners.
EDM is popular for obtaining extremely complex shapes that are difficult to machine with milling. It also has expertise in different applications of hard materials such as titanium. EDM is a material reduction manufacturing technique that uses electrical discharges for machining. There are two types of EDM, wire-cut WEDM and EDM, both of which are discussed below.
Spark machines allow manufacturers to create complex shapes without creating stress in the conductive material.
Because it cannot cut completely (unless required), it is used in a wide range of applications such as cross sections, thin walls and blind holes/keyways.
This versatility makes it an efficient technology and widely used. With a long history in the space travel industry, spark machines have brought the world into a new era by manufacturing parts for rocket engines, satellites and other spacecraft.
EDM Machines
EDM provides durability, accuracy and high quality finishes that can be used in production. Here are some of the benefits of EDM machines
Tough materials can be easily cut using EDM technology
The final product does not require any finishing or polishing
The process cuts through thin materials without causing any damage
EDM is commonly used for 3D contouring, drilling, finishing and deburring.
WCut Electrical Discharge is used for its precision and cost-effectiveness. The benefits of using WEDM is
WEDM is the best choice for machining hard, brittle and friable materials as it allows machining without impacts and pressure
By using copper wire, it makes it easy to cut precise and intricate shapes, WEDM processing is fast, projects can be set up and completed in a very short period of time
Suitable for hardened and special materials (need to be electrically conductive)
