PURPOSE:To obtain an excellent and non-interfered machining liquid column by providing the captioned unit with an overflowed liquid reservoir having an inlet for accepting the machining liquid flowing down from the above of a wire electrode guide and an overflowed liquid discharged outlet at the side face. CONSTITUTION:The machining liquid entered from an inlet 20 is joined to the machining liquid flowed down from a through hole 24b, and jetted from a nozzle 30a to a wire electrode 14 forming a liquid column up to a machining section 100. And, on the clamping body 28 of an electrode guide unit, an opening for accepting the machining liquid and an overflowed liquid reservoir 34 having an outlet 36 at the side face are formed in a body. More than a specified amount of the machining liquid is, therefore, discharged from the outlet 36 and moreover, being not interfered with the discharged machining liquid, the machining liquid of a machining section remains orderly obtaining excellent cooling effect and also being free from occurrence of abnormal electrical discharging caused by a shortage of machining liquid and occurrence of wire electrode cutting. |
