Description

방전가공기 전극선용 동-아연-니켈계 합금 및 그 제조방법{Cu-Zn-Ni alloys for EDM(Energy Discharge Machine) wire and its manufacturing method}Cu-Zn-Ni alloys for Energy Discharge Machine (EDM) wire and its manufacturing method}

본 발명은 방전가공기(Energy Discharge Machine : EDM) 전극선용 동(Cu)-아연(Zn)-니켈(Ni)계 합금 및 그 제조방법에 관한 것으로, 특히 동(Cu)에 대하여 전율고용원소인 니켈(Ni)을 첨가함으로써 β상 조직화의 억제를 유도하여 아연(Zn)의 함량을 높여도 상온에서 인성을 잃지 않게 하여 냉간인발 가공성을 개선하고, 또한 고용원소인 니켈(Ni)을 첨가함으로써 고용강화효과를 가져와 재료의 강도도 높인 합금 및 그 제조방법에 관한 것이다.The present invention relates to a copper-zinc (Zn) -nickel (Ni) -based alloy for an energy discharge machine (EDM) electrode wire and a method of manufacturing the same. The addition of (Ni) induces the suppression of β-phase organization and increases the content of zinc (Zn) so that toughness is not lost at room temperature, thereby improving cold drawing workability and enhancing the solid solution by adding nickel (Ni), a solid solution. The present invention relates to an alloy having a high effect and increasing the strength of a material, and a method of manufacturing the same.

일반적으로 와이어 방전가공은 수중에서 세선의 와이어 전극과 피삭물 간의 방전을 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 for complicated cutting.

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 65%동(Cu)-35%아연(Zn) 합금에 알루미늄(Al), 망간(Mn), 갈리움(Ga), 크롬(Cr) 등을 첨가한 황동선 또는 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 wires of 65% copper (Cu) -35% zinc (Zn) alloys and aluminum (Al) and manganese (65% copper (35) -35% zinc (Zn) alloys). Mn), gallium (Ga), chromium (Cr), etc. Brass wire, or a brass wire or a steel wire plated with zinc (Zn) plated on the surface of the wire is roughly divided into three types, the most commonly used wire diameter 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 가지가 있어야 하겠지만, 그 중에서 절삭속도를 좌우하는 요소는 선재의 합금성분 중에 아연(Zn)의 함량이 많으면 절삭 속도가 양호하다는 것이다.According to the present invention, there should be various conditions to be equipped as the electrode wire of the electric discharge machine, but among them, the factor which determines the cutting speed is that the cutting speed is good when the content of zinc (Zn) in the alloying material of the wire is high.

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 40%까지 높이거나 아연(Zn)의 효과를 얻을 목적으로 기존의 황동합금에 아연(Zn)의 당량을 높이는 효과가 있는 원소인 알루미늄(Al)을 첨가하는 합금이 개발되어 왔다.Therefore, aluminum (Al), an element having the effect of increasing the equivalent of zinc (Zn), is added to the existing brass alloy for the purpose of increasing the content of zinc (Zn) to 40% or obtaining the effect of zinc (Zn) in the brass alloy. Alloys have been developed.

방전가공시 절삭성을 증가시킬 목적으로 전극선재인 황동에 아연(Zn)을 40% 이상 첨가하면 금속기지는 β상의 조직으로 변하여 열간가공성에는 지장이 없으나, 상온에서의 경도가 증가하고 인성이 부족해져 냉간가공성이 급속히 나빠져 세선으로의 인발가공이 매우 곤란하여 실용성이 없어진다는 문제점이 있다.When zinc (Zn) is added 40% or more to brass, an electrode wire, for the purpose of increasing machinability during electric discharge machining, the metal base is transformed into β-phase structure, which does not interfere with hot workability. There is a problem in that workability is rapidly deteriorated, drawing work into thin wires is very difficult and practicality is lost.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은 동(Cu)에 대하여 전율고용원소인 니켈(Ni)을 첨가함으로써 β상 조직화의 억제를 유도하여 아연(Zn)의 함량을 40% 이상으로 높여도 상온에서 인성을 잃지 않게 하여 냉간인발 가공성을 개선하고, 또한 고용원소인 니켈(Ni)을 첨가함으로써 고용강화효과를 가져와 재료의 강도도 높일 수 있는 합금 및 그 제조방법을 제공하는데 있다.An object of the present invention for solving the above problems is to increase the content of zinc (Zn) to 40% or more by inducing the suppression of β-phase organization by adding nickel (Ni), an electrifying employment element to copper (Cu) The present invention also provides an alloy and a method of manufacturing the same, which improve the cold drawing processability by not losing toughness at room temperature, and also have a solid solution effect by adding nickel (Ni), which is a solid solution.

이러한 결과는 아연(Zn)의 함량을 40-45%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 장점이 있다.These results increased the content of zinc (Zn) to 40-45% and a new alloy supplemented 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 merits of the product can be improved by preventing 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.

본 발명에서는 아연(Zn) 함량과 니켈(Ni)의 첨가량의 효과를 최대한 이용하여 아연(Zn)의 함량을 35 ∼ 45%(중량백분율), 니켈(Ni)의 함량을 0.1 ∼ 5.0%(중량백분율)로 하며 나머지는 동(Cu)으로 구성된 방전가공기 전극선용의 새로운 합금을 개발하였다.In the present invention, the maximum amount of zinc (Zn) and the amount of nickel (Ni) is used to make the maximum amount of zinc (Zn) 35 to 45% (weight percentage), and the content of nickel (Ni) is 0.1 to 5.0% (weight). A new alloy was developed for the electrode line of electric discharge machine composed of copper (Cu).

이렇게 니켈(Ni)을 소량 첨가함으로써 재료의 강도와 냉간인발 가공성을 개선하였고, 아연(Zn)의 함량을 높인 새로운 방전가공기 전극선의 개발로 절삭속도를 향상하였고, 금형의 정밀도를 높일 수 있는0.1 mm 이하의 세선의 가공도 용이하게 하였다.By adding a small amount of nickel (Ni), the material strength and cold drawing processability were improved, and the cutting speed was improved by developing a new electric discharge machine electrode wire with a high content of zinc (Zn). The processing of the thin wire of 0.1 mm or less was also made easy.

일반적으로 동합금에 고용원소이며 융점이 높은 니켈(Ni)을 첨가하면 재료의 고온강도도 향상되는 것으로 알려져 있어서 방전시 발생되는 열에 의한 전극선의 고온강도 저하도 막을 수 있을 것으로 본다.Generally, it is known that the high temperature strength of materials is improved by adding nickel (Ni), which is a solid solution element and has a high melting point, to prevent the decrease in high temperature strength of electrode wires due to heat generated during discharge.
