Detail comparison of Sinker EDM vs Wire EDM machining

Product Details: Sinker EDM and Wire EDM are two types of Electrical Discharge Machining (EDM) processes. Sinker EDM uses a custom-shaped electrode to create complex 3D cavities and shapes, while Wire EDM uses a thin wire to cut through materials along a predetermined 2D path. Sinker EDM is ideal for creating blind features, complex geometries, and is often used in mold and die-making. Wire EDM is best for high-precision profile cutting, sample preparation, and separating or splitting materials without causing burrs or distortion.
