る。In a processing device that processes an electrode and a workpiece by energizing while supplying a processing liquid to the processing gap where the electrode and the workpiece face each other with a minute gap, the supply of the processing liquid is applied to the electrode in order to enhance the removal effect of the generated gas. The machining liquid is jetted under pressure into the machining gap from the provided jet hole, or from opposing nozzles when a warm flow hole cannot be formed in the electrode, such as when cutting a wire.

する。However, even this pressurized jet is not sufficient, and especially if there are irregularities on the surface of the processing gap, sludge will form and a sufficient cleaning effect will not work. The present invention aims to improve this drawback by causing high frequency vibrations such as ultrasonic waves to be generated in the machining fluid jet-supplied to the machining gap, and furthermore, the vibrations are caused to resonate in series or in parallel with the machining gap. The present invention is characterized in that a circuit is provided to excite the vibrator using resonant power.

に周りから加工液の噴流が行なえる。When the machining gap is formed by being immersed in the machining fluid in the machining tank, this is mainly used when a flammable fluid such as kerosene oil is used, but when a non-flammable fluid such as water is used as the machining fluid. A machining table is placed in the air, and the machining liquid is poured into the machining gap formed on the machining table. Particularly in the case of wire cutting where jet holes cannot be formed in the electrode, the nozzles are placed facing each other to pour the fluid. Reference numeral 3 denotes a machining liquid jet nozzle, which branches into two in the middle to form nozzles 31 and 32, so that machining liquid can be jetted from the surroundings into the machining gap.

Reference numeral 7 denotes a machining power source which outputs machining pulses using a switching method or a capacitor charging/discharging method, and is connected between the electrode 1 and the workpiece 2 so that the output pulses are supplied.

Reference numeral 8 denotes an inductance for forming the resonant circuit, and the inductance is selected to match the oscillation frequency, and the series resonant circuit of the crystal resonator 4 and the inductance 8 is connected in series in the machining gap to resonate.

経て噴流加工液に作用させる。For example, a resonance frequency of about 1 to 200K is used. When a discharge is generated in the machining gap by the pulses supplied by the machining power source 7, the series resonant circuit of the vibrator 4 and the inductance 8 resonates due to the discharge in the machining gap, and the resonant current flows through the vibrator 4, generating a high frequency. Vibrations are generated and act on the jet machining fluid via the horn 5.

て安定加工に効果が大きい。A resonant circuit resonates with the high frequency of discharge, so it can be made to resonate with any high frequency by changing the circuit constants.
The jet machining fluid can be vibrated at high frequency. In this way, high-frequency vibrations such as ultrasonic waves are applied to the machining liquid supplied in a jet, and by supplying the jet while vibrating, the effect of eliminating machining shoulders etc. that occur in the machining gap is enhanced, and the cleaning effect of the machining gap is improved. . Furthermore, since the permeation effect is enhanced by vibration, it becomes easier to supply machining fluid through a narrow groove such as a wire cut, and a larger amount of machining fluid can be flowed and stable machining can be performed. However, the high-frequency vibration is not an independent vibration caused by an independent power source, but resonates with the discharge in the machining gap of the resonant circuit of the vibrator 4 and the inductance 8, and resonates with the discharge energy, so the vibration is always synchronized with the discharge. By adapting to the machining conditions, generation of a layer in the machining history due to electrical discharge machining,
The additive effect of removal by machining fluid is extremely high, gap cleaning is always performed optimally, and stable machining can be performed by optimizing machining fluid supply and circulation. It also has a great effect on stable processing when cutting wire using pongee wire.

適制御できる。Extremely efficient electrical discharge machining and current machining are possible. In addition, it is possible to vibrate at any high frequency with the power from the machining power source without using a special power source for the vibrating device, and as the machining energy increases, the vibration energy is automatically increased and controlled optimally.
共振回路は加工間隙に直列に設けられ、共振電力を加工

共振回路を加工間隙に並列に接続した例である。The resonant circuit is provided in series with the machining gap, and machining is performed while supplying resonant power to the machining gap, resulting in the effect of improving machining efficiency. FIG. 2 shows an example in which a resonant circuit consisting of a vibrator 4 and an inductance 8 is connected in parallel to the machining gap.

せて放電するから加工速度は更に向上する。This also causes the vibrator 4 to vibrate at high frequency due to the resonant current of the resonant circuit, so that high frequency vibration can be effectively applied to the jet machining fluid. Reference numeral 9 denotes a high-frequency external power source, which is connected to the inductance 81 of the resonant circuit, and can energize the resonant circuit with high-frequency energy. The high frequency power source may be as small as about 5 to 1 OW or less, and the frequency should be about 1 to 200 KHz, which is the resonant frequency. By providing the high frequency power supply 9, the vibration energy of the vibrator 4 can be increased and high frequency vibration can be performed stably.Also, since the high frequency energy is applied to the machining gap and superimposed on the machining pulse and discharged, the machining speed can be further increased. improves.

It is designed to apply high frequency vibrations to the liquid.

Since the vibrator 10 is provided at the tip of the 32 for vibration, the vibration energy acts extremely effectively on the machining gap, and the effect of the vibration can be further increased. The effect of such vibration is, for example, when machining a pongee hole with a tsumugi wire with a thickness of 0.5 skin, if the machining depth is 2 or more, the required machining will be done by 1.
It was possible to process it in a short time. FIG. 4 shows a case where a jet machining liquid is vibrated by forming a jet hole 11 in the electrode 1 and a vibrator tip horn 5 is inserted into the jet hole.

ができる。By applying high frequency vibration to the jet liquid, the machining speed is usually increased by at least about 30%. It should be noted that applying vibration to the electrode jet hole 11 as in this example is most effective near the machining gap, but if a vibrator cannot be installed in the jet hole due to the size and shape of the electrode 1. can be provided on either of the machining fluid supply pipes 12.

As described above, the present invention can generate arbitrary vibrations using a resonant circuit, and since the resonant circuit resonates with the discharge in the machining gap, it is controlled in relation to the discharge, and is always adapted to the best condition. By acting on the jet machining fluid, machining stability can be improved and machining can be performed at high speed and with high efficiency.
