Electric spark machining electrode

The utility model relates to an electric spark machining electrode which comprises a base plate and a detachable electrode body fixed on the base plate, and the electrode body comprises a plurality of red copper sheets which are sequentially arranged from front to back. The front side and the rear side of any one red copper sheet are each provided with a partition block, and the upper side of any partition block is flush with the upper side of any one red copper sheet. The upper side of each red copper sheet is upwards provided with an arc-shaped protruding sheet, correspondingly, the upper side of each partition block is upwards provided with an arc-shaped protruding block, and the radius of each arc-shaped protruding block is smaller than that of each arc-shaped protruding sheet. According to the utility model, the cost of the electrode is greatly reduced and the processing technology is simplified; meanwhile, the processing difficulty and the maintenance difficulty are effectively reduced; in addition, the
