Technical Reference Burr-Free EDM Machining Guide EDM avoids conventional cutting burrs because there is no shearing tool, but rough discharge, debris, recast, and handling can still affect the edge. A visually clean edge can still have recast, microchipping,… Technical Reference EDM Export Review Basics Start an EDM export review by confirming the material, end use, destination, drawing revision, and required documentation before accepting a restricted or sensitive project. Overusing compliance language slows normal quotations, while ignoring… Technical Reference EDM For Medical Components Medical-component EDM planning links process access to material traceability, clean edges, small features, functional surfaces, and post-process acceptance. Overly broad medical wording cannot replace exact material, drawing, cleanliness, edge, and surface criteria. Technical Reference EDM Machining Process Guide EDM machining is a family of non-contact processes that remove conductive material with controlled electrical discharges. Wire EDM makes through profiles, Sinker EDM makes blind forms, Small Hole EDM makes deep small… Technical Reference What Is Micro EDM? Micro EDM uses very small electrodes and low-energy discharges to produce sub-millimeter holes, slots, cavities, and profiles without cutting force. Its defining limits are electrode wear, micron-scale gap stability, flushing, and metrology.… Technical Reference What Is Sinker EDM? Sinker EDM uses a shaped electrode—typically graphite or copper—to reproduce its form as a blind cavity in conductive material. The electrode never touches the workpiece; pulsed sparks erode the cavity shape across… Technical Reference What Is Small Hole EDM Drilling? Small Hole EDM uses a rotating tubular electrode with pressurized dielectric pumped through its center to drill small, deep holes in conductive material. Rotation helps maintain straightness, and internal flushing clears debris… Technical Reference What Is Wire EDM? Wire EDM cuts a programmed through profile with a continuously moving wire electrode in deionized water. The wire never touches the workpiece, and it must pass completely through the material from an…
