一部が放電柱で急激に蒸発。[Conventional technology] Wire-cut electric discharge machining requires only a small distance from the workpiece.
71 wire-shaped with 11 intervals (10-odd IL)! A pole is installed, the workpiece is moved while spraying machining fluid, and when it reaches the desired location, it is intermittently discharged, and the heat locally softens and melts the workpiece, and the workpiece is machined. Part of the liquid evaporates rapidly in the discharge column.

気中で被加工体に局部的に噴射させるため、被加工液に
よる乾潤状態が繰り返されることが多い。It vaporizes, blows off the molten part with its strong pressure, and at the same time cools the fine powder of the workpiece and discharges it out of the system. Unlike the die-sinking method, in which the workpiece is machined while immersed in the machining fluid, wire-cut electric discharge machining uses the machining fluid to be sprayed locally onto the workpiece in the atmosphere, so the drying process caused by the workpiece fluid is prevented. The wet state is often repeated.
従来、放電加工液としては、炭化水素油が使用されてい
たが、着火の問題があるため、近年、純水系の不燃性加
工液が主流となりつつある。Conventionally, hydrocarbon oil has been used as the electrical discharge machining fluid, but due to the problem of ignition, pure water-based nonflammable machining fluids have become mainstream in recent years.

気伝導度が調整される。Normally, this processing fluid is reused after being drained and the SS* component is removed by *filtration. Water is passed through the resin tower to remove soluble impurities in the liquid, and then reused (normally, the electrical conductivity of the processing liquid is 1o-ioolS).
/ cm. ). This is because if the electrical conductivity of the machining fluid increases, electrical discharge machining with good machining accuracy cannot be expected, and the electrical conductivity of the machining fluid is adjusted by the ion exchange treatment.

問題を生ずることとなる。By the way, in wire-cut electrical discharge machining, the workpiece is exposed to a severe corrosive environment in which the workpiece is repeatedly wetted by the machining fluid as described above.Moreover, in this method, narrow groove-like gaps are formed, making the machining difficult. Machining chips such as chips from the workpiece, electrodes, wires, etc. that are sometimes generated tend to adhere (remain). However, once the processed chip is attached,
An oxygen concentration cell is formed there, and the workpiece, especially metal workpieces such as steel, is extremely susceptible to rust. Zero rusting not only deteriorates the appearance of the workpiece, but also reduces machining accuracy. This causes many problems such as inhibiting high-order processing for finishing.

スト等の面で極めて不経済となる。For this reason, machining fluids made by adding rust preventive agents to pure water have traditionally been used to prevent rust on workpieces, and known ionic rust preventive agents such as nitrites and phosphates have been added It was proposed (Japanese Unexamined Patent Publication No. 51-147096). However, the addition of ionic rust inhibitors increases the electrical conductivity of the machining fluid, reducing machining accuracy, and requires the ion exchange resin tower to be constantly operated, resulting in a decrease in the rust inhibitor concentration in the machining fluid. This is extremely uneconomical in terms of shortening the life of the ion exchange resin and increasing operating costs of the resin tower.

No. 57-132931), etc. have been proposed.

こととなる。[Problems to be Solved by the Invention] However, none of the conventional rust preventive agents achieves a sufficiently satisfactory effect.Among the above conventional rust preventive agents, sugars can be said to be relatively preferable; In order to prevent rusting of the workpiece to which processed chips are attached during the above-mentioned processing using only sugars, it is necessary to add a large amount. In this case, new problems arise such as the area around the processing machine becoming sticky due to splashes of the processing fluid containing a high concentration of nonionic rust preventives such as sugars.

It has excellent anti-rust and anti-corrosion effects, and ■ Since it is non-ionic, it does not increase the electrical conductivity of the machining fluid, so it does not increase the load on the ion exchange tower and allows precision machining. It is.
■ 二元糖や還元糖アルコールの必要添加量を大幅に低
減することができる。■ The required amount of binary sugars and reducing sugar alcohols can be significantly reduced.
■ このため、加工液飛沫による加工機周辺のベトつき
を防止することができる。- Therefore, it is possible to prevent the area around the processing machine from becoming sticky due to splashes of processing fluid.
等の利点を有する。It has the following advantages.
このため本発明のワイヤカット用放電加工液によれば、
経済的かつ高い加工精度のもとに、良好な加工を行うこ
とが可能とされる。Therefore, according to the electrical discharge machining liquid for wire cutting of the present invention,
It is possible to perform good machining economically and with high machining accuracy.
