What is wire EDM?

Wire electrical discharge machining cuts or shapes metal workpieces using a thin electrode wire controlled by a CNC. The wire is charged with electric current, and sparks form between the wire and the workpiece, melting its surface. The cutting wire never contacts the workpiece directly, so there’s no distortion in the cutting path or the shape of the material.

Who uses our wire EDM services?

We provide wire EDM services to part manufacturers, mold builders and die makers nationwide.

Our clients include:

  • Manufacturers with in-house EDM departments (to supplement their existing capabilities)
  • Tool and die shops that do not have wire EDM capabilities
  • OEMs & contract manufacturers who do not have their own wire EDM equipment

Many of our clients are production machining providers manufacturing metal parts who need our help with large projects or challenging components. We are uniquely focused on wire EDM contract services, making us the ideal company to closely partner with. XACT’s wire cut EDM services also provide fast, precise solutions to manufacturers in need of highly accurate dies, punches, ejector plates and bridge strippers.

Wire EDM In Action

Advantages of Wire EDMwire EDM cutting services

Compared to other precision metal cutting processes, wire EDM has many advantages:

  • No custom tooling required – delivery times are short
  • No cutting forces present – virtually no burrs generated
  • Workpiece material hardness does not affect cutting speed
  • Improved surface finishes – no additional finishing or polishing needed
  • Tools & metal parts are machined after heat treatment – dimensional accuracy is maintained
  • Highly repeatable with no deformation
  • Ability to stack, string & nest multiple parts
  • Ideal for delicate & complex parts
  • Tight tolerances & precise fits
  • Small corners & radii
  • Narrow slots & thin walls

Wire EDM cutting is ideal when the workpiece material doesn’t lend itself to conventional machining, for example hardened tool steels and exotic materials.

Wire EDM Capabilities

  • Tolerances to +/-.0001”
  • Pieces up to 16” thick can be machined
  • 4-axis & intricate contours
  • High taper
  • Small diameter wires
  • Auto-threading
  • Submerged cutting for thermal stability & efficient interrupted cutting
  • Anti-electrolysis power supply
  • Prototyping
  • Medium-volume runs
  • High-volume production

Fine wire EDM (aka small wire EDM or micro wire EDM) uses very fine wire electrodes to meet exacting requirements for very small parts. We offer EDM cutting using wire as small as 0.004” for incredibly precise and repeatable results.

As a highly experienced wire EDM supplier, we’ve learned that partnering with clients at the front end of projects can be highly beneficial. XACT can provide a wealth of design for manufacturability suggestions to improve production speed, accuracy, and finished part quality.

Wire Cut EDM Applications

Wire EDM cutting is an option for metal components that require cuts through the entire thickness of the raw material. Wire EDM services are ideal for projects requiring intricate tolerances, materials too brittle for stamping, and limited material stress and heating.

Our engineers and machinists have an extensive understanding of best EDM machining practices and materials as they apply to many different industries and applications, including but not limited to:small wire EDM, fine wire EDM, micro wire EDM


Our team is comprised of industry specialists who are familiar with industry requirements, standards and practices. Simply producing parts to print without a serious pre-production review often leads to higher costs, lower production volumes, and sub-optimal piecework. Let our experts go over your requirements and ask the right questions based on years of production experience.
