Abstract

The invention relates to a compound electrode. The compound electrode comprises a first part comprising conductive metal and a second part comprising tungsten alloy; the second part and the first part are jointed along the length direction of the compound electrode; the second part comprises a machining tail end which is away from the first part and is used for machining a workpiece. The invention also relates to a machining device comprising the compound electrode and a machining method using the compound electrode. The compound electrode is wear-resistant.

Description

technical field [0001] The present invention relates to a combined electrode, a processing device comprising the combined electrode and a processing method using the combined electrode, in particular to a combined electrode comprising a first part and a second part of different materials. Background technique [0002] Electroerosion Machining (EEM) is to process the workpiece into a certain shape by melting the part of the workpiece to be removed by electric spark or electric arc. A DC voltage is supplied between the workpiece and the electrode to create a spark or momentary arc. A gap of about 0.01 mm to about 0.50 mm is left between the tip of the electrode and the workpiece, and is immersed in the machining fluid. The machining fluid in the gap is partially ionized by the DC voltage, and an electric spark or an instantaneous arc is generated between the electrode and the workpiece. The spark and / or arc generates enough heat to melt a small amount of workpiece material, ...
