Precision EDM Milling Equipment & Services

EDM machine costs vary widely depending on type, size, and capabilities. Entry-level sinker EDM machines can start around $50,000, while advanced gantry-style sinker EDM systems like those from OPS Ingersoll can range significantly higher. WSM Technology offers pricing available on request, and the team can help match you with the right machine for your budget and application.

EDM machining is capable of achieving extremely tight tolerances, typically in the range of ±0.0001" to ±0.001" (±0.0025 mm to ±0.025 mm) depending on the machine, material, and process parameters. High-precision sinker EDM machines, such as those from OPS Ingersoll, are specifically engineered for demanding applications where dimensional accuracy and surface finish are critical.

EDM milling equipment is widely used in mold and die making, aerospace, and automotive industries. It is also applied in micro mechanics, textile machinery, and precision tool and die shops. Any sector requiring complex geometries in hard, conductive materials benefits from EDM technology's ability to machine with minimal mechanical stress.

Sinker EDM uses a shaped electrode (often graphite) to erode a cavity into a workpiece, making it ideal for mold cavities and die sinking. Wire EDM uses a thin wire to cut through material along a programmed path, suited for through-cuts and punch/die profiles. WSM Technology offers expertise in both types across its product portfolio.

Every EDM machine purchase through WSM Technology includes installation service, local training, and access to advanced training programs. Technical support is available on an ongoing basis, and EDM consumables are supplied through WSM's affiliated CPG Department and Encore Group. Test cut services are also available to help validate equipment performance before and after purchase.

Yes. WSM Technology operates a Demonstration Center in Rootstown, Ohio, where prospective buyers can evaluate equipment hands-on. Test cuts are available to compare technologies or prove out new processes. This allows manufacturers to make confident, informed purchasing decisions before committing to a machine investment.
