The present invention relates to a wire cut electrical discharge machining device.

There are four effects: ) insulation recovery between the poles, (2) discharge explosion generation, (3) cooling of the discharge machined part, and (4) removal of machining powder.

粉はできるだけ速やかに除去されるのが望ましい。That is, when an electric discharge occurs between the two electrodes, that is, between the wire electrode and the workpiece, the electric discharge point is rapidly heated to cause evaporation and melting, and the explosive force of the electric discharge causes the evaporated and melted portion to scatter, and the machining progresses. After the discharge ends, the machining fluid rapidly cools the machined part and restores the insulation between the electrodes. In addition, the wire electrode becomes high temperature due to Joule heat due to discharge heat and machining current, making it easy to break, but it is cooled by machining fluid to prevent wire breakage.
Insufficient cooling between the wire electrode and workpiece electrode may cause the wire to break, so ensure that the wire in that area is sufficiently covered with machining fluid, and that machining powder generated by electrical discharge is removed as quickly as possible. It is desirable that

が講じられていた。In this way, the machining fluid is supplied between the wire electrode and the workpiece electrode. For this purpose, for example, as shown in FIGS. 3 to 5, a nozzle l is provided on the workpiece 4 through which the wire electrode 3 passes. When the machining fluid flows through the nozzle, it splashes on the workpiece, so in order to prevent this machining fluid from splashing, conventionally a sponge 2 was placed around the outlet of the nozzle l, as shown in FIG. ’ or
As shown in FIG. 4, a plastic material 2'' such as acrylic is provided around the outlet of the nozzle 1, or a gap 5 is provided around the nozzle 1 as shown in FIG. Measures were taken such as providing a cylindrical fixing part at the outlet.

うことができないという問題があった。(Problems with the prior art) With the conventional cover attached to the nozzle to prevent machining fluid from splashing, for example, if the wire electrode passing through the nozzle breaks, it is difficult to connect the wire electrode and repair it. Whenever the need arises, use the above-mentioned sponge,
It was extremely difficult to handle, as it required removing the acrylic or other plastic and re-passing the wire electrodes. Further, even when it is desired to easily inspect the electrical discharge machined part, there is a problem in that the above-described conventional machining fluid splash prevention means cannot easily inspect the electrical discharge machined part.
