Wire EDM Capabilities
Wire Electrical Discharge Machining (Wire EDM) is a non-traditional machining process that uses a thin, electrically charged wire (typically 0.004"-0.012" diameter brass or molybdenum) to cut through electrically conductive materials. The wire never touches the workpiece; instead, rapid electrical discharges (sparks) between the wire and workpiece erode material with extreme precision. Wire EDM can cut any conductive material regardless of hardness, making it ideal for hardened tool steels, tungsten carbide, and exotic alloys that are difficult to machine conventionally. It produces burr-free cuts with surface finishes as smooth as 8 Ra microinches and tolerances as tight as ±0.0001".
±0.0002" (±0.005mm) standard; ±0.0001" achievable

Wire EDM in Hartford — FAQ
How many Wire EDM providers are in Hartford, CT?
The Hartford-East Hartford-Middletown metropolitan area has approximately 900 manufacturing establishments, many of which offer wire edm services. The area employs about 28,000 manufacturing workers, ensuring a skilled workforce for your project.
What is wire EDM used for?
Wire EDM is used for cutting precision die and mold components, medical implants, aerospace parts, extrusion dies, gears, splines, and any part requiring tight tolerances in hard materials. It is essential in the tool and die industry for cutting hardened steel punches and dies.
How thick of material can wire EDM cut?
Wire EDM can cut through material up to 16-20" thick, though most applications involve material under 6" thick. The process speed decreases with thickness, and taper accuracy is affected by very thick workpieces.
Can wire EDM cut hardened steel?
Yes, wire EDM cuts hardened materials (60+ Rc) as easily as soft materials because it uses electrical erosion, not mechanical cutting. This is one of its biggest advantages — parts can be heat-treated to final hardness, then wire EDM cut to final dimensions.
What surface finish does wire EDM achieve?
Wire EDM achieves surface finishes of 8-16 Ra microinches (0.2-0.4 Ra μm) with skim cuts (multiple passes). This is smoother than most grinding operations and eliminates the need for polishing in many applications.
