Abstract
Sparking machining device that produces a succession of mechanical discharges between a piece and an electrode that serves as a machining tool, in which the electrical energy that ensures the operation of the device is in the form of alternating voltage, characterized in that a magnetic switch of the ferro-resonant type is intended to control the action of said voltage so as to produce unidirectional intermittent electric discharges between the electrode-tool and the part that is machined without having to rectify the alternating voltage by the usual and in particular electronic means.
