Technical Field

[0001] The utility model relates to the technical field of electric spark cutting, in particular to a water spray nozzle for an electric spark wire cutting machine tool. Background Art

[0002] Wire EDM machines are usually equipped with water jets. Wire EDM is a precision cutting process that uses the principle of electric spark discharge to cut metal materials into the desired shape. The main function of the water jet is to cool and clean the cutting area to prevent overheating and improve the cutting quality. Therefore, in wire EDM machines, water jets are usually equipped to assist in cutting.

[0003] When the traditional wire-cut EDM machine tool water nozzle sprays coolant on the cutting wire, the coolant is relatively dispersed, which can easily lead to the bottom cutting wire not being protected by the coolant, which may cause the cutting wire or the workpiece to have a high temperature, affecting the workpiece cutting effect and reducing the precision.
