This directory lists 92 edm machining companies across the United States, from precision contract manufacturers specializing in micro-EDM for medical devices to job shops equipped for large-scale production of aerospace components.
Buyers often grapple with finding suppliers who can consistently deliver parts with exacting surface finish requirements, particularly when dealing with the post-machining effects like the recast layer or avoiding burrs in delicate features. Many need partners capable of cutting hardened materials where conventional machining is impractical, or achieving extremely tight tolerances on intricate geometries, often involving complex flushing for deep pockets or through-holes.
The range of suppliers spans from dedicated EDM houses focusing solely on wire, sinker, and small-hole EDM, to full-service machine shops offering EDM as one capability among many. Specialist shops might excel in specific niches like micro-EDM for semiconductor components or large-format Wire EDM for die plates, while generalists provide broader support but might lack the deep technical expertise for highly challenging applications.
Effective collaboration requires buyers to provide comprehensive specifications, including material type and hardness, required surface finish (e.g., Ra values), specific geometric tolerances, and any critical post-processing steps like recast layer removal. Suppliers, in turn, expect well-defined CAD models (often 2D profiles for wire, 3D solids for sinker), clear instructions for flushing internal features, and details on intended application to recommend optimal machining strategies.
A significant trend in EDM machining is the increasing adoption of automated cell manufacturing and real-time process monitoring, particularly for Wire EDM. This shift aims to reduce labor costs, improve consistency for high-volume production, and allow for unattended operations, addressing the ongoing demand for greater efficiency and tighter delivery schedules.

Wire EDM typically achieves smoother finishes, often in the 16-32 Ra range, especially with multiple skim cuts. Sinker EDM can achieve comparable finishes, sometimes down to 8 Ra with specialized orbiting strategies and fine electrodes, but generally requires more careful process control to avoid a textured finish from the sparking.
The recast layer (also known as the white layer) is a thin, re-solidified layer of material that forms on the surface during EDM due to the rapid heating and cooling cycles of the electrical discharge. It can be harder and more brittle than the base material, potentially reducing fatigue strength or corrosion resistance. For critical applications, post-processing like acid etching or abrasive finishing is often required to remove it.
Yes, Wire EDM is particularly effective for machining stacked materials (e.g., multiple plates of the same material) simultaneously, improving efficiency. For dissimilar metals, it's possible, but careful consideration of electrical conductivity differences, material thickness, and flushing is crucial to maintain accuracy and prevent wire breakage, as spark gap and energy settings vary.
Small Hole EDM (also known as a Hole Popper) is ideal for creating deep, small-diameter holes in extremely hard or tough materials (like hardened tool steel, Inconel, or carbide) where conventional drilling would cause excessive tool wear, breakage, or simply isn't feasible. It's also excellent for starting holes for Wire EDM or creating precise cooling holes in turbine components.
Beyond material and part geometry, key factors include the required surface finish, depth of cavities (influencing flushing strategy), number and complexity of electrodes needed, machine setup time, and the volume of parts. Very tight internal corner radii, blind features, and mirror-like finishes significantly increase complexity and cost due to specialized electrodes and longer cycle times.
For Wire EDM, 2D vector formats like DXF or DWG are often sufficient for profile cutting. For Sinker EDM and more complex geometries, 3D solid models in STEP, IGES, Parasolid, or native SolidWorks/Inventor formats are highly preferred, as they allow for direct programming and ensure accurate translation of intricate cavity designs.
