EDM Machines

With an EDM machine, you can work on hard and difficult-to-machine materials in a precise and economical way. Use a wire cut EDM machine or die sinking EDM machine to produce and forge dies, injection moulds or die-casting moulds from graphite, electrically conductive ceramics and metals and their alloys. For this purpose, KNUTH offers you both the EDM machine for beginners and the CNC EDM machine, featuring a high speed wire with complex application possibilities, high removal rate and low electrode wear.

FAQ's

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.
