Wire EDM Machining

For straight lines, sharp corners and smooth finishes

Wire electrical discharge machining (WEDM) is typically used to cut plates as thick as 300mm and to make punches, tools, and dies from hard metals that are difficult to machine with other methods. In this process, a thin single-strand metal wire (often brass, is fed through the workpiece, submerged in a tank of dielectric fluid, typically deionized water.

Common applications are prototype production, coinage die making, small hole interpolating, metal disintegration machining, and closed-loop manufacturing. Here are some of the benefits:

  • Complex shapes
  • Extremely hard material to very close tolerances
  • Very small work pieces
  • Delicate sections and weak materials can be machined without perceivable distortion
  • Good to very good surface finish
  • Very fine holes
  • Tapered holes
  • Pipe or container internal contours and internal corners down to R .001″.
