Abstract

Die Erfindung betrifft eine Vorrichtung zum Schleifen der Spitzen von Wolfram-Elektroden mit einer angetrie­ benen Schleifscheibe (3) und einem Elektrodenhalter für ei­ ne darin um ihre Achse drehbar gelagerte Elektrode (15), wo­ bei der Elektrodenhalter auf einem Drehteller (9) angeordnet ist und der Drehteller um eine zur Achse (6) der Schleif­ scheibe (3) orthogonale Achse schwenkbar sowie in Richtung der Achse der Schleifscheibe zustellbar ist. Um den Ein­ fluß von Verformungen der Wolfram-Elektroden beim Schlei­ fen der Elektrodenspitze zu verringern, soll der Elektro­ denhalter einen Träger (13) für eine die Elektrode aufnehmen­ de Spannzange (14) aufweisen, wobei der Träger feste Wider­ lager (16, 17) für das elektrodenferne Ende der Spannzange und für das freie Elektrodenende sowie ein im mittleren Bereich der Spannzange (14) angreifendes und diese gegen die festen Widerlager drückendes Gegenlager (18) aufweist. The invention relates to a device for grinding the tips of tungsten electrodes with a driven aben grinding wheel (3) and an electrode holder for egg ne therein rotatably mounted around its axis electrode (15), where arranged at the electrode holder on a turntable (9) is and the turntable about one to the axis (6) of the grinding disc (3) orthogonal axis pivotable and in the direction the axis of the grinding wheel is adjustable. To the one flow of deformations of the tungsten electrodes during grinding The electrode should reduce the tip of the electrode the holder receive a support (13) for an electrode de Collet (14), the carrier fixed against bearings (16, 17) for the end of the collet remote from the electrode and for the free end of the electrode and one in the middle the collet (14) and this against the fixed Counter bearing pressing abutment (18).
