ABSTRACT:
A method of and an apparatus for the electroerosive machine of a workpiece in which a tool electrode, such as a traveling wire, traverses a nozzle which coaxially directs into the machining gap a mixture of water vapor and liquid water. The liquid water is drawn into the nozzle by the suction created by the passage of steam therethrough and the proportions of liquid water and water vapor in the machining fluid are controlled in response to gap conditions. The water vapor or steam is generated by heating a body of water in the apparatus.
