| titleOfInvention | Electric discharge machining method for insulating material using electroconductive layer formed thereon |
| abstract | An insulating material is electric discharge machined with high dimensional accuracy at a high speed, by closely adhering mesh-shaped electroconductive material 5 onto the surface of an insulating material 1 so as to form an electroconductive layer 6 at the initial stage of electric discharge. In the advancement of electric discharge, fresh electroconductive layers 9, 10 are continuously formed at the bottom and the side surface of a hole 8, so that the electric discharge machining is continued even after the hole 8 becomes deeper. A porous preformed body composed of fine metal wires or a complex body containing needle metal may be used instead of the mesh-shaped electroconductive material 1. Thus, electric discharge machining is performed at a high speed, and a machined surface excellent in flatness can be obtained with high dimensional accuracy. |
