発明は、このような問題点を解決することを目的
としている。(c) Problems to be Solved by the Invention However, since the conventional liquid jet processing method described above uses water to suspend the abrasive, it is difficult to process a large amount of abrasive particles with relatively large diameters. There was a problem that it was difficult to supply. In order to improve the machining efficiency of the liquid jet machining method, it is necessary to supply a large amount of abrasive material with as large a particle size as possible. However, there are limits to the size and amount of abrasive particles that can be transported by water, making it impossible to obtain the desired processing efficiency. In particular, the longer the distance between the abrasive material supply location and the processing location where the suspension is actually sprayed, the more difficult it becomes to transport the abrasive material with water. The present invention aims to solve these problems.

ので、切削性能が大幅に向上する。(E) Action A suspension of abrasive material in a heavy liquid with a high specific gravity is mixed with high-pressure water. Because heavy liquid has a high specific gravity, it is difficult for the abrasives in the mixed state to settle and separate, and it is also able to transmit greater kinetic energy to the abrasive particles, making it possible to transport a large amount of abrasives with large diameter particles. I can do it. In addition to the increased particle size and amount of abrasive, the speed of the abrasive is also increased, resulting in significantly improved cutting performance.

つ、切削を続けることができる。 Next, the operation of this embodiment will be explained. The suspended heavy liquid adjustment tank 22 contains water, heavy liquid material, surfactant, and abrasive material (particles such as silica sand and garnet).
is supplied and adjusted to a predetermined concentration and specific gravity.
Surfactants are intended to increase hydrophilicity and facilitate suspension of the abrasive in heavy liquids. The suspended heavy liquid adjusted by the suspended heavy liquid adjustment tank 22 is transferred to the pipe line 2.
8 to the suspended heavy liquid supply tank 14. The suspended heavy liquid supply tank 14 supplies a fixed amount of suspended heavy liquid to the high-pressure water pipe 26 per unit time. High-pressure water pressurized by the high-pressure pump 12 is supplied to the high-pressure water pipe line 26 . Therefore, the suspended heavy liquid supplied from the suspended heavy liquid supply tank 14 to the high-pressure water line 26 is mixed with the high-pressure water flowing through the high-pressure water line 26 and conveyed to the mixing chamber 16. On the other hand, high-pressure water is also supplied to the mixing chamber 16 from a high-pressure water pipe 24 . High-pressure water from the high-pressure water line 24 and high-pressure water supplied with the suspended heavy liquid from the high-pressure water line 26 are mixed in the mixing chamber 16, and then injected from the injection nozzle 18 toward the workpiece 30. This allows the workpiece 30 to be cut. Since the abrasive material is transported by heavy liquid, it is possible to transport abrasive materials with large particle sizes, and also to transport a large amount of abrasive materials. Furthermore, the speed of injection from the injection nozzle 18 is also improved. This greatly improves the cutting performance and allows the workpiece 30 to be cut efficiently. Water, suspended heavy liquid, and the like used for cutting the workpiece 30 are recovered to the reprocessing device 20. Regeneration processing device 20
Then, the water and surfactant, the heavy liquid material, and the chips and abrasive material are separated into three parts, and the water and surfactant are returned to the suspended heavy liquid adjustment tank 22 through the pipe 34, and the heavy liquid is The material is also returned to the suspended heavy liquid adjustment tank 22. The abrasive material and chips are disposed of (note that abrasive materials with large particle sizes can be sorted and reused). Suspended heavy liquid adjustment tank 22
Now, the water and surfactant recovered from the conduit 34 and the recovered heavy liquid material are reused to prepare a suspended heavy liquid having the same concentration and specific gravity as described above. This allows cutting to continue while reusing expensive heavy liquid materials.

This improves cutting performance. Furthermore, since a heavy fluid is used, the jetting speed of the abrasive can be increased, which also improves cutting performance.
In addition, since the abrasive material is transported by heavy liquid, it is difficult for the abrasive material to settle and separate, and a stable flow state is obtained, so the location of the suspended heavy fluid supply tank and the location of the injection nozzle are relatively The abrasive material can be transported even from a distance, improving work efficiency. Also,
If used liquids are collected and heavy liquid materials are recycled, the amount of expensive heavy liquid materials used will be reduced.
The cost required for processing can be reduced.
