PatentansprücheClaims 1. Verfahren zum elektrochemischen Formentgraten von Kreuzung'sstellen schwer zugänglicher Bohrungen in sehr großen und schweren Maschinenbauteilen, insbesondere bei Ölkanälen von Kurbelwellen und Pleuelstangen, bei dem austauschbare Formelektroden zur Anwendung kommen und das Entgraten und die Nachbehandlung unmiütelbar nacheinander erfolgen, dadurch gekennzeichnet, daß die parallel zueinander anreordneten Rohrelektroden (1) aller au bearbeitender Bohunten eines Maschinenbauteiles (2) sowohl Teil eines Elektrolytkreislaufes (3) als auch eines Nachbehandlungskreislaufes (4) sind, indem der Elysierstrom zeitverzögert durch das Fließen des Elektrolyten eingeschaltat und nach einer mittels eines Relais einstellbaren Bearbeitungszeit zusammen mit; diesem durch das Schließen eines Ventils (5) abgestellt wird, sich daran ein seitlich begrenztes Ausblasen der in den Arbeitsräumen der Rohrelektroden (1) und Leitungen (23) verbliebenen Elektrolyten anschließt, über den dem Elektrolytkreislauf (3) analogen Kreislauf (4) ein Nachbehandlungsmittel durch die Arbeitsräume geführt wird, worauf ein nochmaliges Ausblasen derselben durch geführt wird und alle Verfahrensschritte zwangsläufig aufeinanderfolgen.1. Process for electrochemical deburring of intersections difficult to access holes in very large and heavy machine components, in particular for oil ducts of crankshafts and connecting rods, where replaceable molded electrodes come into use and deburring and post-treatment in close succession take place, characterized in that the tubular electrodes arranged parallel to one another (1) of all au processing Bohunten of a machine component (2) as well as part of a Electrolyte circuit (3) and an aftertreatment circuit (4) are by the electrolyte current is switched on with a time delay due to the flow of the electrolyte and after a processing time that can be set by means of a relay together with; this is turned off by closing a valve (5), turn it on to the side Limited blowing out of the tube electrodes (1) and lines in the working spaces (23) connected to the remaining electrolyte, via which the electrolyte circuit (3) analog circuit (4) a post-treatment agent passed through the work rooms whereupon another blowing out of the same is carried out and all process steps inevitably follow one another. 2. Verfahren zum elektrochemischen Formentgraten nach Anspruch 1, dadurch gekennzeichnet, daß der Zlektrolyt aus dem Elektrolytbehälter (12) nach Einschalten einer Pumpe (6) über eine Rohrleitung (7) durch einen Filter (8), das Ventil (5) und die Rohrelektroden (1) in die Arbeitsräume fließt und von dort über einen durch eine Umsteuereinrichtung (9) schwenkbaren Abfluß (10) über einen Abs@tzbehälter (11) wieder in den Elektrolytbehälter (12) gelangt.2. A method for electrochemical deburring according to claim 1, characterized in that the electrolyte from the electrolyte container (12) after Switching on a pump (6) via a pipe (7) through a filter (8), the Valve (5) and the tubular electrodes (1) flows into the working spaces and from there over an outflow (10), which can be pivoted by a reversing device (9), via a sedimentation container (11) enters the electrolyte container (12) again. 3. Verfahren zum elektrochemischen Formentgraten nach Anspruch 1, dadurch gekennzeichnet, daß das sachbehandlungsmittel aus einem Behälter (13) mittels einer i>umpe (14) durch eine Rohrleitung (15) über einen Filter (16) und ein Ventil (17) in die Arbeitsräume der Rohrelektroden (1) und von dort über den durch die Umsteuereinrichtung (9) zum Behälter (13) gestellten Abfluß (10) wieder in den Behälter (13) fließt.3. A method for electrochemical deburring according to claim 1, characterized in that the material treatment agent from a container (13) by means of an i> umpe (14) through a pipe (15) via a filter (16) and a Valve (17) into the working spaces of the tubular electrodes (1) and from there over the through the reversing device (9) to the container (13) provided drain (10) back into the Container (13) flows. 4. Verfahren zum elektrochemischen Formentgraten nach Anspruch 1 bis 3, dadurch gekennzeichnet, daß die zum ausblasen der Arbeitsräume der Xohrelektrouen (1) benötigte Luft aus einer Druckluftleitung (18) durch ein Redazierventil (19), ein Ventil (20) und ein Rückschlagventil (21) in die Arbeitsräume gepreßt wird und von dort ins Freie gelangt.4. A method for electrochemical deburring according to claim 1 to 3, characterized in that the to blow out the work spaces of the Xohrelektrouen (1) required air from a compressed air line (18) through a reducer valve (19), a valve (20) and a check valve (21) is pressed into the working spaces and from there into the open air.
