The utility model discloses a from repairing tool electrode grinding formula electrical discharge machining device mainly includes tool electrode and metal block, wherein, tool electrode includes metal substrate and concreties in the abrasive particle layer on metal substrate surface through electrically conductive grit binder, tool electrode can just can move along workpiece surface around self axis rotation, the metal block compresses tightly on tool electrode's abrasive particle layer, when using, rotatory tool electrode grinding metal block, thereby the abrasive particle layer that the piece that the grinding in -process produced arrived tool electrode with the adhesion goes up formation metal adhesion layer, utilize this adhesion layer to carry out electro -discharge machining(EDM), spark effect in the course of working can cause the loss of adhesion layer, yet the adhesion layer of loss will be through tool electrode grinding metal block and obtain supply rebuilding once more, use, this life who has pro
