Title (EN) ELECTRICAL DISCHARGE MACHINE
(FR) MACHINE À DÉCHARGE ÉLECTRIQUE
Abstract:
(EN) An EDT apparatus (1) is disclosed, comprising a dielectric fluid return System for use with an EDT machine of the type in which the workpiece is not submersed in dielectric fluid. The return system comprises a first collector (19) for catching spills from a dielectric bath (9) associated with a set of electrodes (10) which apply electrical pulses to the workpiece through the dielectric fluid in the bath. Also, a separate, second collector (21) is positioned substantially beneath the workpiece and arranged both to receive fluid from the first collector (19) and to catch fluid that drips from the workpiece itself, the second collector being connected to a pump (13) which returns the fluid from the second collector to the dielectric bath.
(FR) Cette invention concerne un appareil de surfaçage par décharge électrique (1), comprenant un système de retour de fluide diélectrique destiné à être utilisé une machine de surfaçage par décharge électrique du type qui ne procède pas à l'immersion de la pièce à usiner dans un fluide diélectrique. Ledit système de retour comprend un premier collecteur (19) conçu pour recueillir les pertes issues d'un bain diélectrique (9) associé à un ensemble d'électrodes (10) qui appliquent des impulsions électriques sur la pièce à usiner à travers le fluide diélectrique dans le bain. De plus, un second collecteur distinct (21) est positionné sensiblement en dessous de la pièce à usiner et conçu à la fois pour recevoir un fluide provenant du premier collecteur (19) et pour recueillir le fluide qui s'écoule de la pièce à usiner elle-même, le second collecteur étant relié à une pompe (13) qui renvoie le fluide provenant du second collecteur vers le bain diélectrique.
