How wire EDM cutting works

Wire EDM cutting, also known as electrical discharge machining, is a process that uses an electrically energized thin wire to slice through metal. This method uses rapid, controlled, repetitive spark discharges from the wire to the workpiece, thereby eroding the metal away. The workpiece must be electrically conductive.


Wire EDM can provide high dimensional accuracy for close fitting parts. The process can make sharp inside corners. EDM can cut material thickness from only a few thousandths of an inch to several inches. Custom tooling is generally not needed.


The wire EDM process can cut most any simple or complex 2D shape including cutouts and thin walls, intricate openings and sharp inside corners. Examples of a few types of parts include: Custom gearsCustom robot parts, punch and die tooling, stripper plates and mold components. 



Wire EDM cutting can be applied to AluminumStainless SteelCopperSteelBrassTitaniumSpring SteelBronze, super alloys and very hard and difficult to machine metals. 


Cost optimization 

Cost optimization options include:

  • Reducing cut surface area

  • Stacking parts during cutting 

  • Minimizing the number of holes and cutouts 

  • Creating holes by providing a small gap connecting the hole to the outer edge.


Design Considerations

  • Edges are smooth but matte. 

  • Typical surface finish is between 16 and 64 microinches. 

  • The edges of the finished work piece will have virtually no burrs. 

  • Kerf width typically ranges from 0.001" to 0.012". 

  • Sharp internal corners will be slightly rounded (typically with radius ~.008").
