If you use a short electrode when attaching the electrode to one (drill chuck, etc.), the main shaft will be submerged in the machining fluid, and when the electrode is rotated for machining, the machining fluid will scatter around. In addition, if the electrode is short, the workpiece is hidden in the spindle, making it difficult to see the machining status, so there is a problem that the amount of short electrode used is very small and the amount of inventory increases. . Moreover, even when using a long electrode, the machining liquid is applied from the side between the electrode and the workpiece during the work, making it impossible to discharge discharge debris and resulting in longer machining time.

で電極保持装置の軸の中心にあける。The material of the electrode holding device shown in Figure 1 should be energized and made of as hard a material as possible, and the parts that connect to the collet chuck, etc. (the narrow diameter part of the electrode holding device) shown in Figs. 4 and 5 should be polished (cylindrical grinding, etc.). , set the dimensions according to the size of the electrode to be used and the collet chuck to be used. However, the dimensions are set so that the concentricity between the main shaft and the electrode holding device can be maintained when the electrode holding device is attached to the main shaft. The electrode holding device and the cut for tightening the electrode in 10 are made so that the spanner can fit depending on the size of the spanner used.
Decide accordingly. The cut surface of the cut part for positioning in No. 11 is polished for alignment of the electrode (used as a reference for electrode shape processing and for alignment in the X and Y directions when attached to an electrical discharge machine). It is a finished surface. The size of the female screw for installation in step 2 is determined according to the size of the electrode and electrode holding device, but when using a jet flow, use a screw with a size as close as possible to the outer diameter of the thinner side of the electrode holding device. Set. (Set the dimensions as large as possible within a range that does not cause problems in terms of strength.) It is sufficient that the depth is about twice the thread diameter. The jet hole 8 has a size close to the hole diameter of the main shaft jet hole 7 and is bored at the center of the shaft of the electrode holding device.

の固定は終了である。Next, the basic method of use is to cut 4 male threads to match the female threads of the electrode holding device 2.The electrode material at this time can be of any type, round or square. The length of the screw is
The same length as the screw diameter is sufficient. (For example, if it is M6, 6lIll is sufficient) To attach the electrode material with a cut male thread to the electrode holding device, place the electrode material in a vise or lathe holding device (collet chuck, three-way tightening, etc.). Hold the electrode and screw in the electrode holding device.Finally, apply a spanner to the cut part 10 and tighten with enough force that the external thread of the electrode material will not break. This completes the fixing of the electrode material and the electrode holding device.

Make the directions parallel and implement shape processing. At this time, if the shape is suitable for jet machining, holes for jet machining are made in the electrode material as shown in FIGS. 4 and 9. At this time, the range of the hole to be drilled is raised to the position that covers the external thread part 4. structure aBA
As mentioned above, for this reason, it is better to make screws 2 and 4 as large as possible.

となる。In actual machining, as shown in FIG. 4, the parts 1, 5, and 6 are tightened and fixed to the main shaft part of the electrical discharge machine. At this time, when using a jet stream, press 1 tightly against the main shaft and fix it so that the jet stream 7 can be reliably connected to 8. After this, the concentricity of the electrode holding device and the main shaft part is determined, and the X. Perform parallel alignment in the Y direction. The electrode set is now complete, and normal discharge work can be carried out. If the electrode material has jet holes, jet machining is also possible.
