Product Introduction

Electrical Discharge Machining (EDM), also referred to as spark erosion or electro-discharge machining, represents a non-conventional manufacturing technique that employs regulated electrical sparks for material removal from conductive components. The core mechanism requires preserving a microscopic inter-electrode gap between a tool electrode (commonly fabricated from copper, graphite, or similar conductive substances) and a workpiece electrode immersed in dielectric medium (like kerosene or deionized water). Through pulsed electrical energy, cyclic spark discharges create localized transient heat exceeding 8,000–12,000°C, resulting in material fusion or vaporization to accomplish controlled material elimination.

A distinctive attribute of EDM lies in its contact-free operation, permitting the processing of all electrically conductive materials irrespective of their hardness—rendering it particularly advantageous for machining high-strength, high-toughness substances. This method demonstrates exceptional capability in generating sophisticated geometries, delicate micro-structures, and profound narrow recesses that pose challenges to conventional removal techniques. Categorized by electrode configuration and movement, EDM principally comprises two variants:

• Ram/Sinker EDM: Utilizes a pre-fabricated three-dimensional electrode to transfer its contours onto the workpiece, extensively employed in mold cavities, turbine blades, and intricate sculpted forms.
• Wire EDM: Operates with a continuously fed slender metallic wire (typically molybdenum or brass) serving as the tool electrode, directed by computerized numerical control to section intricate two-dimensional outlines, proving especially valuable for precision stamping dies, templates, and shaped through-holes.

Essential operational variables encompass pulse on-time, pulse off-time, peak amperage, discharge potential, and electrode retraction management. Contemporary EDM equipment frequently integrates adaptive regulation systems, intelligent spark monitoring, and multi-axis CNC capabilities, substantially improving process consistency, exactness, and automated operation. Machined surfaces generally display a signature micro-pitted morphology, where targeted surface finish (as fine as Ra 0.1 μm) can be attained through meticulous parameter optimization. Nevertheless, EDM exhibits constraints including comparatively slow removal rates, electrode degradation, confinement to conductive workpieces, and dielectric fluid handling necessities.
Propelled by technological developments, EDM is progressing toward enhanced productivity, improved accuracy, increased aspect-ratio machining capacity, and advanced intelligent control. Growing integration with additive manufacturing and laser processing establishes hybrid manufacturing approaches. Presently, EDM has evolved into a vital foundational technology within sectors including aerospace precision components, medical apparatus, precision tooling, automotive powertrain elements, and microelectronic device fabrication.
