Abstract:
The invention relates to a machine for machining a part by micro-electrical discharge machining, said machine comprising a mechanism (44, 45, 46, 48) for modifying the configuration of the machine so as to alternatively and reversibly switch from a machining configuration to a sharpening configuration in which the tip of a same etching electrode (20) and another electrode (64) are dipped in an electrolyte bath in order to sharpen the tip of the etching electrode by electrochemnical corrosion.
