Abstract
(EN)
An electrical discharge machine (10) supplies a machining area of a machining object (13) with a wire electrode (W) stored in a guide tube (70). The electrical discharge machine is provided with a hollow cylindrical drive shaft (40), which has a space for storing the guide tube storing the wire electrode along a center axis (Z) in the vertical direction and is arranged in the vertical direction. A head (50) is provided with a first holding section (54) for holding the guide tube and a second holding section (62) for holding the wire electrode protruding from a lower end opening of the guide tube, and is removably arranged at the lower end of the drive shaft. Therefore, the wire electrode can be replaced by replacing the head.
(FR)
L’invention concerne un poste de soudure électrique (10) qui fournit du fil-électrode (W) stocké dans un tube de guidage (70) à une zone d’usinage d’un objet à usiner (13). Le poste de soudure électrique est dotée d’un arbre moteur à cylindre creux (40), qui a un espace pour stocker le tube de guidage renfermant le fil-électrode le long d’un axe central (Z) dans le sens vertical et qui est agencé à la verticale. Une tête (50) est pourvue d’une première section de préhension (54) pour tenir le tube de guidage et une deuxième section de préhension (62) pour tenir le fil-électrode qui dépasse d’une ouverture à une extrémité basse du tube de guidage, et qui est agencé de manière amovible à l’extrémité basse de l’arbre moteur. Le fil-électrode peut donc être remplacé par un remplacement de la tête.
(JA)
 ガイドチューブ(70)に収容されているワイヤ電極(W)を被加工物(13)の加工領域に供給する放電加工装置(10)は、ワイヤ電極を収容したガイドチューブを上下方向の中心軸(Z)に沿って収容するための空間を有する、垂直方向に配置された中空円筒状の駆動軸(40)を備えている。ヘッド(50)は、ガイドチューブを保持する第1の保持部(54)と、ガイドチューブの下端開口から突出したワイヤ電極を保持する第2の保持部(62)を備えており、駆動軸の下端に着脱自在に設けられている。したがって、ヘッドを交換することによりワイヤ電極が交換できる。
