シング液さして送給さねる。A workpiece (7) is disposed between these units AB, and predetermined machining is performed by causing an electric discharge between the wire electrode (8) and the workpiece (7). At this time, the machining fluid supplied from the machining fluid supply device (9) fills the holder (3), cools the power supply bottle (2) and the wire electrode (8), and is formed at the tip of the holder (3). One tongue nozzle part (3
Cooling liquid and flushing liquid are also fed from a) to the processing section of the workpiece (7).
上記のように構成された従来のワイヤカット放電加工装

なると、このワイヤ電極自身の腰が弱くなって挿入の操
作性が低下するという欠点があつ′ｒ：、。By the way, when inserting the wire electrode into the die-shaped guide or power supply pin, if the wire electrode has a diameter of about 0.2 fl or more, the wire electrode itself is strong and can be easily inserted. E. Kaji: If the wire electrode is thinner than that, it has the disadvantage that the wire electrode itself becomes weak and the ease of insertion is reduced.

そねだけ容易に挿入することができる。(2) is the power supply plate to the wire electrode (8), (to) is the holder that holds and fixes the above-mentioned kite αυ and the power supply plate bending, and the 0th station is combined with this holder αυ with 1 piece and 1 piece. A water storage block 7 and 10 υ is formed by the holder and the holder. Then, the machining fluid supplied from the machining fluid supply device (9) fills the holder (7), cools the power supply plate (2) and the wire electrode (8), and cools the holder (7). A groove is formed at the tip of the chair-shaped guide.
The cooling liquid and flushing liquid are also supplied from the discharge port (1) a) to the processing section of the workpiece (7). Inserting the wire electrode (8) into αp 1
When this (14) is removed, the power supply plate @1 is exposed, and the guide αD is thinner, so the wire electrode kite can be made smaller and the T-piece can be made even closer to the workpiece (7). Only the spine can be inserted easily.
