ZNC-controlled electrical discharge machine with manually positioned work reservoir for tool and die making
CNC wire eroding machine with reciprocal high-speed eroding wire system
The principle behind EDM (Electrical Discharge Machining) is the use of electrical discharges or spark erosion to remove material from a workpiece. In this process, a wire electrode is used to generate an electric spark that melts a portion of the workpiece, which is then removed by flushing with a dielectric fluid.
EDM and ECM are both electrical discharge machining processes. EDM uses a wire electrode to produce sparks that melt and remove material from the workpiece, while ECM uses an electrochemical process to remove material. ECM is typically used for machining extremely hard electrically conductive materials or for intricate workpieces that require high precision.
Electrical discharge in engineering refers to the release of electrical energy in the form of sparks or discharges. EDM process is based on thermoelectric energy between the workpiece and an electrode. Electrical discharge machining is widely used to produce dies, punches, molds, and finishing parts.
Electrical discharge machining uses a wire electrode fed through a machine, such as wire-cut EDM or sinker EDM. The wire electrode is charged with high-voltage electricity, which produces sparks or discharges that melt a small portion of the workpiece. The melted material is then removed by flushing with a dielectric fluid. The process is then repeated, producing a precise and accurate finished product. The depth of the cuts made during electrical discharge machining can be adjusted by changing the plunge rate, which is the rate at which the wire electrode penetrates the workpiece.
