摘要

Improvements in the circuits for a spark erosion machine with an accumulator-free generator and verification of the working gap in which in the machining gap between the part and the tool electrode there is a DC voltage source connected by means of such a high resistance, which can not maintain any independent discharge, and in which a measuring device derives from the machining gap the characteristic voltage for the desired state of the interstitium in question, characterized in that between the input of the measuring member and the machining gap are connected to a capacitor and a resistor which is preferably adjustable, which in the case of a disruptive discharge of the machining gap transmits to the measuring device a voltage point corresponding to the magnitude of the voltage reached before the spark-gap discharge. the interstitium, in such a way that said measurement organ does not trigger a new generator erosion pulse, until the amplitude of the supplied voltage tip exceeds a characteristic value for the desired physical state of the machining gap.
