Subtract’s Electrical Discharge Machining (EDM) services utilize non-contact spark erosion to cut and shape conductive metals with extreme precision—achieving tolerances as tight as ±0.0001″ without mechanical force, stress, or burrs. Subtract processes hardened tool steels, exotic alloys, and delicate geometries that traditional cutting tools cannot machine.

• Wire EDM: High-precision traveling wire cuts intricate two-dimensional profiles, narrow slots, tight internal radii, and full-thickness vertical contours with micron-level accuracy.

• Sinker EDM: Custom-shaped electrodes plunge into workpiece materials to form deep blind cavities, sharp internal corners, hex sockets, and detailed mold tooling.

Backed by the Subtract Network, every job includes complete material traceability, CMM inspection verification, and seamless scaling from single-part toolmaking to ongoing production components.
