This method is used for manufacturing various molds and the like. In such wire electric discharge machining, the electric discharge machining characteristics such as the finish of the workpiece, that the machining accuracy and the finished surface condition are good, that the electrode wire does not adhere to the workpiece, and that the electric discharge machining time is short are low. Has been requested. As an electrode wire for electric discharge machining used for such wire electric discharge machining, a brass wire has been conventionally used because it has excellent wire drawing workability and strength as an electrode wire.
［発明が解決しようとする課題］ 最近では、加工電源の改良進歩に伴い、放電加工速度

ている。[Problems to be Solved by the Invention] Recently, with the advancement of the improvement of the machining power supply, an electrode wire capable of improving the electric discharge machining speed is desired. In particular, when a power supply of a wire electric discharge machine that applies a high-voltage and short-time pulse voltage is used, an electrode wire that can increase the electric discharge machining speed is desired.

極線では、十分に速い放電加工速度を得ることができな
かった。また被加工物への電極線の付着量も多く、また
高速で放電加工をしようとすると断線しやすいという欠
点もあった。However, with a conventional electrode wire for electric discharge machining using a brass wire, a sufficiently high electric discharge machining speed could not be obtained. In addition, there is also a disadvantage that the amount of electrode wire attached to the workpiece is large, and that if electrical discharge machining is performed at a high speed, the wire is easily disconnected.
この発明の目的は、放電加工時間を短くすることがで
き、かつ電極線が被加工物に付着しにくいワイヤ放電加
工用電極線を提供することにある。SUMMARY OF THE INVENTION It is an object of the present invention to provide an electrode wire for wire electric discharge machining, which can shorten an electric discharge machining time and is less likely to cause the electrode wire to adhere to a workpiece.
［課題を解決するための手段および発明の作用効果］ この発明によるワイヤ放電加工用電極線の１つは、Zn
を38〜50質量％含有し、残部がCuからなるCu合金からな
る。Zn含有量を38〜50質量％としたのは、38質量％未満
では放電加工速度の向上の効果が少なく、また50質量％
を超えると細線への加工が困難になるからである。[Means for Solving the Problems and Effects of the Invention] One of the electrode wires for wire electric discharge machining according to the present invention is Zn.
Of 38 to 50% by mass, with the balance being Cu. The reason why the Zn content is set to 38 to 50% by mass is that when the content is less than 38% by mass, the effect of improving the electric discharge machining speed is small, and the content is 50% by mass.
This is because if it exceeds, processing into a fine wire becomes difficult.
この発明において、好ましくはZn含有量は40〜50質量
％であり、さらに好ましくは40〜46質量％である。In the present invention, the Zn content is preferably from 40 to 50% by mass, and more preferably from 40 to 46% by mass.
この発明に従えば、従来電極線として用いられている
黄銅よりも多くのZnを含有することにより、放電加工速
度が向上し、かつ被加工物への付着量が少なくなる。ま
た放電加工中における断線も少なくすることができる。According to the present invention, by containing more Zn than brass conventionally used as an electrode wire, the electric discharge machining speed is improved, and the amount of adhesion to the workpiece is reduced. Further, disconnection during electric discharge machining can be reduced.
この発明の好ましい実施態様の１つに従うワイヤ放電
加工用電極線は、Znを40〜50質量％含有し、さらにZrを
0.01〜1.0質量％含有し、残部がCuからなるCu合金から
なる。The electrode wire for wire electric discharge machining according to one of the preferred embodiments of the present invention contains 40 to 50% by mass of Zn and further contains Zr.
It is made of a Cu alloy containing 0.01 to 1.0% by mass, with the balance being Cu.

め、この実施態様では、Zrを0.01〜1.0質量％含有させ
ることにより、加工性を改善している。When the content of Zn is increased, the electric discharge machining characteristics are improved, but since a β phase is generated, the machining method similar to the conventional method,
There is a problem that processing into a fine wire becomes difficult. Therefore, in this embodiment, the workability is improved by containing 0.01 to 1.0% by mass of Zr.

くなり、1.0質量％を超えると加工性改善の効果が飽和
するとともに放電加工速度が遅くなるためである。ま
た、Zn含有量が50質量％を超える場合には、Zrの添加効
果があまり認められなくなる。The present inventors have conducted various studies on the relationship between the wire drawing workability and the electric discharge machining characteristics of the added element when the Zn content exceeds 40% by mass, and as a result, the Zn content is 40 to 50%. It has been found that when the amount of Zr is 0.01% to 1.0% by mass, the β phase is finely divided and the drawability in cold is improved.
This embodiment is based on such findings. The reason for setting the Zr content to 0.01 to 1.0% by mass is that when the Zr content is less than 0.01% by mass, the effect of workability improvement decreases, and when the Zr content exceeds 1.0% by mass, the effect of processability improvement saturates. This is because the electric discharge machining speed becomes slow. On the other hand, when the Zn content exceeds 50% by mass, the effect of adding Zr is hardly recognized.
また、Zrの添加は、単に加工性を改善するのみなら
ず、放電加工速度等の放電加工特性の改善をもたらす。Further, the addition of Zr not only improves the workability but also improves the electric discharge machining characteristics such as the electric discharge machining speed.

It is composed of a Cu alloy containing at least one element selected from the group consisting of Ti, Mg, Bi, and Mn in a total amount of 0.001 to 0.05% by mass, with the balance being Cu.

At least one element selected from the group consisting of i and Mn is added. The present inventors have found that the addition of such an element makes the β phase finer, not only enables cold drawing, but also improves the electric discharge machining speed and smoothens the surface properties. .

うな効果が飽和してしまうからである。The content of these elements is set to 0.001 to 0.05% by mass. When the content is less than 0.001% by mass, the effect of improving electric discharge machining characteristics such as machining speed and surface properties and cold drawing processability is obtained. This is because such an effect is saturated when the content is less than 0.05% by mass.

It is not less than 01% by mass and less than 0.5% by mass.

This is because it saturates.
