In either case, the servo of the electrode 1 is driven only in the machining depth direction;
There is no relative movement between and the workpiece 2. Therefore, since the part of the electrode 1 facing the workpiece 2 does not change even as machining progresses, the wear of the electrode 1 corresponds to the part facing the workpiece, that is, the thickness of the workpiece 2. It occurs only in a limited area. This 1. In this case, the electrode wear rate is expressed as the ratio of the cutting length of the workpiece to the electrode wear length in the feeding direction, and there is a problem that this electrode wear rate becomes extremely large.

ことになる。Next, the detailed structure in the vicinity of the machining pole 14 will be described with reference to FIG. As shown in the figure, a current-carrying terminal 20 is attached to the main shaft 13 via an insulating bushing 19, and an electrode 14 is held by a leaf spring 21 and an electrode guide bushing 22. The machining fluid flowing into the machining fluid supply path 17 provided inside the main shaft 13, which is simultaneously achieved by this holding mechanism to melt the machining electrode 14, is

4 and is ejected from the machining fluid ejection hole 18. As shown in FIG. 4, the branch channels 24 are formed in a radial shape, deviating from the radial direction of the processing electrode 14 in a certain direction. By the way, by adjusting the tightening of the nut 15, the machining electrode 14 is connected to the machining fluid supply passage 17 inside the main shaft 13 and the annular groove 23 inside the machining pole 14, as shown in the figure.
and are fitted in the insulating bushing 19 with appropriate fitting tolerances. Follow me,
The machining fluid that has flowed in through the machining fluid supply path 17 flows into the annular groove 23.
The machining fluid is discharged from the machining fluid jet hole through the branch flow path 24, but since the discharge direction at this time deviates from the radial direction, the machining electrode 4 rotates due to the reaction of the discharged machining fluid.

In addition, in the same figure, 26 is a machining fluid scattering prevention cover. In this case, as described above, the machining electrode 14 performs selective machining while rotating, so that the entire electrode 14 is uniformly worn out. Therefore, compared to conventional electric discharge machining equipment, the wear rate of the magnetic poles is suppressed to a low level, and its lifespan can be extended. In addition, the short-circuit phenomenon that often occurs during sheet forming is often caused by machining debris, but according to the electric discharge machining apparatus of the above embodiment, the short-circuit occurs due to the mutual effect C between the rotation of the electrode 14 and the machining fluid. The occurrence can be significantly suppressed.
