Because they are high-precision machine tools, wire EDM machines are top-rated in the automotive, medical, and aerospace industries. However, they help make prototypes or for full production runs and are often employed in the manufacturing industry for metal components and tools. The EDM process is favored for applications requiring low levels of residual stress.
Here are the three leading industries of EDM machining:
Automotive Industry
The automotive industry requires a manufacturing process for parts with complex shapes using hard materials. Because of this, they favor using wire EDM machines because the process does not rely on mechanical forces that lead to tool wear, and the wire electrode does not need to be stronger than the workpiece. The process works well for making holes and cavities for parts like bumpers, dashboards, and car doors.
Medical Industry
EDM machines produce accurate parts in all medical fields, including optometry and dentistry. They are used to manufacture medical equipment parts and components and medical and dental implants and syringe components without affecting their structural integrity.
Aerospace Industry
Wire EDM produces close-tolerance parts for aerospace part manufacturers. This process benefits parts unable to withstand the high temperature and stress associated with traditional cutting tools. For example, many of these components-engines, turbine blades, and landing gear parts-require accuracy and an excellent surface finish.
