ABSTRACT:
An improved machining-liquid supply system for traveling-wire electroerosion machining is disclosed which comprises a machining-liquid ejecting nozzle disposed on one side of a workpiece and traversed by the traveling wire electrode for injecting a thin stream of the machining liquid into the cutting zone in the workpiece. A cover member is disposed proximate to and so as to surround, the end of the cutting zone on the other side of the workpiece and is formed with a drain duct communicating with a suction source to forcibly draw the machining liquid injected into the cutting zone by the machining-liquid ejecting nozzle. The system further comprises a coolant-ejecting nozzle disposed so as to coaxially surround the machining-liquid ejecting nozzle for ejecting a stream of coolant and enclosing therewith the stream of the machining liquid being injected into the cutting zone.
