일반적으로 와이어 방전가공은 수중에서 세선의 와이어 전극과 피삭물 간의방전을 제어하여 공작물을 가공하는 방법으로, 주로 복잡하게 절단하려는 금형가공에 사용되고 있다.In general, wire discharge machining is a method of processing a workpiece by controlling the discharge between the wire electrode of the fine wire and the workpiece in water, and is mainly used for mold processing to cut intricately.
그러나 금속뿐만 아니라 도전성이 있는 것이라면 초경합금이나 세라믹스 등과 같이 난가공성 재료의 가공에도 정밀성이 있어서 향후 확대보급이 확실시되고 있다.However, if the conductive material is not only metal but also conductive, the processing of hard-working materials such as cemented carbide and ceramics is precise, and the expansion and expansion is assured in the future.
현재 방전가공기 전극선으로서 보편적으로 사용되고 있는 재료는 65%동(Cu)-35%아연(Zn) 합금인 황동선과 최근에는 동(Cu)-20∼40%아연(Zn) 합금에 알루미늄(Al), 갈리움(Ga), 크롬(Cr), 망간(Mn) 중에서 1종 또는 2종 이상을 0.1 ∼ 5.0% 이하로 첨가한 합금황동선을 비롯하여 황동선이나 강철선 표면에 아연(Zn)을 도금한 도금선 등의 3 종류로 대별되며, 가장 많이 사용되는 선경은0.20 ∼ 0.30 mm가 주류를 이루나 정밀가공용으로는0.1 mm 이하의 선재도 사용되고 있다.Currently, materials commonly used as electrode wires for electric discharge machines are brass wire, which is a 65% copper (Cu) -35% zinc (Zn) alloy, and recently, aluminum (Al), copper (Cu) -20-40% zinc (Zn) alloy. An alloy brass wire in which one or two or more of gallium (Ga), chromium (Cr), and manganese (Mn) is added in an amount of 0.1 to 5.0% or less, as well as a plating wire in which zinc (Zn) is plated on a brass or steel wire surface. It is divided into three kinds of, and the most used line diameter is 0.20 to 0.30 mm is the mainstream, but for precision processing Wire rods of 0.1 mm or less are also used.
지금까지 밝혀진 바에 의하면 방전가공기 전극선재로서 갖추어야 할 조건은 여러 가지로 많으나, 이 중에서 절삭속도를 좌우하는 요소는 선재의 합금성분 중에 아연(Zn)의 함량이 많을수록 양호하였다.According to the present invention, there are many conditions to be equipped as the electrode wire of the electric discharge machine, but among these, the factor which determines the cutting speed is better as the content of zinc (Zn) in the alloy component of the wire is higher.
이는 방전시 발생되는 열이 증발하는 아연(Zn)과 함께도 소모되기 때문이며, 합금중에 아연(Zn)의 함량이 높을 수록 그 만큼 방열효과도 큰 것으로 확인되고 있다.This is because heat generated during discharge is also consumed with evaporated zinc (Zn), and the higher the content of zinc (Zn) in the alloy, the greater the heat dissipation effect.
따라서 황동합금에서 아연(Zn)의 함량을 높이거나 아연(Zn)의 효과를 얻을 목적으로 기존의 황동합금에 아연(Zn)의 당량을 높이는 효과가 있는 원소인 알루미늄(Al)을 첨가하는 합금이 개발되어 사용중이다.Therefore, an alloy that adds aluminum (Al), an element having the effect of increasing the equivalent of zinc (Zn) to the existing brass alloy, in order to increase the content of zinc (Zn) or to obtain the effect of zinc (Zn) in the brass alloy. It is developed and in use.
방전가공시 절삭성을 증가시킬 목적으로 전극선재인 황동에서 아연(Zn)을 40% 이상 첨가하면 금속기지는 β상의 조직으로 변하여 열간가공성에는 지장이 없으나, 상온에서의 경도가 증가하고 인성이 부족하여져서 냉간가공성이 급속히 나빠져 세선으로의 인발가공이 매우 곤란하여 실용성이 없어진다는 문제점이 있다.When zinc (Zn) is added 40% or more in brass, an electrode wire, to increase machinability during electrical discharge machining, the metal base is changed into β-phase structure, which does not interfere with hot workability, but increases hardness at room temperature and lacks toughness. There is a problem in that cold workability is rapidly deteriorated and drawing process to thin wire is very difficult and practicality is lost.
상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 알루미늄(Al)을 첨가하여 고용 및 석출강화 효과에 의해 재료의 강도를 높이고, 스트론튬(Sr)을 미량 첨가하여 주상정에서의 공정조직을 미세화시키거나, 티타늄(Ti)과 보론(B)을 미량 첨가하여 주상정 자체를 미세화시키거나, 스트론튬(Sr), 티타늄(Ti)및 보론(B)을 함께 첨가하여 주상정에서의 공정조직을 미세화시킴과 아울러 주상정 자체를 미세화시켜 취성을 억제시킴으로써 열간 및 냉간가공성을 개선하여 아연(Zn)의 함량이 높거나 아연(Zn) 당량이 높은 재질이라도 그 선재제조를 용이하게 하는 합금 및 그 제조방법을 제공하는데 있다.An object of the present invention for solving the above problems is to add aluminum (Al) to increase the strength of the material by the solid solution and precipitation strengthening effect, and to add a small amount of strontium (Sr) to refine the process structure in the columnar tablets Alternatively, a small amount of titanium (Ti) and boron (B) may be added to refine the columnar tablet itself, or strontium (Sr), titanium (Ti) and boron (B) may be added together to refine the process structure in the columnar tablet. In addition, by improving the hot and cold workability by minimizing the columnar tablet itself to suppress brittleness, an alloy and a method of manufacturing the same, which facilitate the manufacture of the wire even in a material having a high content of zinc (Zn) or a high content of zinc (Zn). To provide.
이러한 결과는 아연(Zn)의 함량을 40.1-45%까지로 증가시켰으며 강도와 인성을 알루미늄(Al), 스트론튬(Sr), 티타늄(Ti), 보론(B) 등의 첨가로써 보완한 새로운 합금으로 절삭속도가 15-20% 개선되었고 절삭시 과열에 의한 피절삭면의 변색을 방지하여 상품성을 높이는 등의 장점을 나타내었다.These results increase the content of zinc (Zn) to 40.1-45% and complement the strength and toughness with the addition of aluminum (Al), strontium (Sr), titanium (Ti) and boron (B). As a result, the cutting speed has been improved by 15-20% and the merchandise is improved by preventing the discoloration of the cutting surface due to overheating during cutting.
상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명의 실시예인 구성과 그 작용을 상세히 설명하면 다음과 같다.When explaining the configuration and the operation of the embodiment of the present invention to achieve the object as described above and to perform the problem for removing the conventional defects in detail.

The limited ranges of the types and amounts of added elements are obtained through numerous experiments. The range that satisfies the enemy is extracted. The effect of the roughness range thus obtained is described in detail in the effects of the invention to be described later.
이렇게 알루미늄(Al), 스트론튬(Sr), 티타늄(Ti) 및 보론(B) 등을 적당량 첨가함으로써 재료의 강도와 냉간인발 가공성을 개선하였고, 아연(Zn)의 함량이나 당량을 높인 새로운 방전가공기 전극선의 개발로 절삭속도를 향상하였고, 금형의 정밀도를 높일 수 있는0.1 mm 이하의 세선의 가공도 용이하게 하였다.As such, aluminum (Al), strontium (Sr), titanium (Ti) and boron (B) are added in an appropriate amount to improve the strength of the material and cold drawing workability, and a new electric discharge machine electrode wire which increases the content or equivalent of zinc (Zn). To improve cutting speed and improve mold precision. The processing of the thin wire of 0.1 mm or less was also made easy.

By improving the hot and cold workability by inhibiting brittleness, even an alloy having a high content of zinc (Zn) or a high content of zinc (Zn) provides an alloy and a method of manufacturing the same that facilitate the manufacture of the wire.
이러한 결과는 아연(Zn)의 함량을 40.1-45%까지로 증가시켰으며 강도와 인성을 알루미늄(Al), 스트론튬(Sr), 티타늄(Ti), 보론(B) 등의 첨가로써 보완한 새로운 합금으로 절삭속도가 15-20% 개선되었고 절삭시 과열에 의한 피절삭면의 변색을 방지하여 상품성을 높이는 등의 장점을 나타내었다.These results increase the content of zinc (Zn) to 40.1-45% and complement the strength and toughness with the addition of aluminum (Al), strontium (Sr), titanium (Ti) and boron (B).

다음의 표 1은 본 발명에서 제시하는 합금들의 예이며, 표 2는 이러한 합금재로 만든0.25 mm의 선경을 갖는 방전가공기용 와이어로써 합금공구강재인 STS-11 금형강을 대상으로 절단시험한 결과를 나타내는 것이다.Table 1 below is an example of the alloys presented in the present invention, Table 2 is made of such an alloy material This is a wire for electric discharge machining machine with 0.25mm wire diameter and shows the result of cutting test on STS-11 mold steel which is alloy steel.
표 2에서 보면 아연(Zn)과 첨가원소의 함량이 증가할수록 선재의 파단강도가 증가하여 고강도화가 되며, 아연(Zn)의 함량이 낮고 첨가원소의 함량만 많아지면 금형강의 피절단면의 경면성이 좋지 않음을 나타내었다.In Table 2, as the content of zinc (Zn) and added elements increases, the breaking strength of the wire increases, resulting in high strength. When the content of zinc (Zn) is low and the content of added elements is high, the specularity of the cut surface of the mold steel is increased. It was not good.
그러나 모든 경우에 있어서 절단가공시 선재로부터 발생되는 가루의 량은 적음을 나타내었다.In all cases, however, the amount of powder generated from the wire rod during cutting was small.
