적층식 연마 및 절삭 공구 제조방법{METHOD OF MANUFACTURING STACKING TYPE POLISHING AND CUTTING TOOL}METHODS OF MANUFACTURING STACKING TYPE POLISHING AND CUTTING TOOL}

본 발명은 연마 및 절삭 공구 제조방법에 관한 것으로, 보다 상세하게는 단층의 연마층을 여러층 적층함으로써 복수 층의 연마층을 갖는 연마 및 절삭 공구 제조방법에 관한 것이다.
The present invention relates to a polishing and cutting tool manufacturing method, and more particularly, to a polishing and cutting tool manufacturing method having a plurality of polishing layers by stacking a single layer of a polishing layer.

일반적으로 다이아몬드 전착, 융착, 및 세그먼트 타입 공구의 경우 직접 피삭재의 가공(연마, 절단)에 관여하는 다이아몬드 지립의 수명 연장과 연마, 절삭 성능의 향상에 관해 많은 노력과 연구가 진행되어져 왔다.In general, in the case of diamond electrodeposition, fusion, and segment type tools, much effort and research has been conducted on the extension of the life of the abrasive grains involved in the processing (grinding, cutting), grinding, and improvement of cutting performance.

전착공구의 경우 도 1에 도시된 바와 같이 샹크(10) 위에 니켈(Ni) 도금층(30)을 형성하여 연마지립(20)을 기계적으로 구속하여 피삭재 가공 중 연마지립이 이탈되지 않도록 하는 방식으로 제조되고, 융착공구의 경우 도 2에 도시된 바와 같이 샹크(10)에 본딩재(40)와 연마지립을 도포한 후 본딩재(40)의 융점 이상으로 가열하여 본딩재(40)와 연마지립(20) 간 화학적 결합을 생성시켜 피삭재 가공 중 연마지립의 이탈을 방지하는 방식으로 제조된다.In the case of the electrodeposition tool, as shown in FIG. 1, a nickel (Ni) plating layer 30 is formed on the shank 10 to mechanically restrain the abrasive grains 20 so as to prevent the abrasive grains from leaving during processing of the workpiece. In the case of a fusion tool, as shown in FIG. 2, the bonding material 40 and the abrasive grains are applied to the shank 10, and then the bonding material 40 and the abrasive grains are heated by heating above the melting point of the bonding material 40. 20) It is produced in such a way as to produce chemical bonds between the particles to prevent the removal of abrasive grains during workpiece processing.

또한, 세그먼트 타입 공구의 경우, 도 3에 도시된 바와 같이 연마지립(20)과 여러가지 금속분말을 균일하게 혼합하여 가열 가압, 소결함으로써 기계적 및 금속간 결합을 생성시켜 피삭재 가공 중 연마지립의 이탈을 방지하는 단층의 세그먼트 팁(50)을 샹크(10)에 용접하는 방식으로 제조된다.In addition, in the case of the segment type tool, as shown in FIG. 3, the abrasive grains 20 and various metal powders are uniformly mixed and heated, pressurized, and sintered to generate mechanical and intermetallic bonds, thereby eliminating the abrasive grains during machining. It is manufactured by welding a single-layered segment tip 50 to the shank 10.

그러나, 이와 같은 일반적인 전착 또는 융착에 의한 단층의 연마지립을 갖는 연마공구의 경우 피삭재의 가공에 직접 관여하는 1층의 연마지립이 가공 중 파손, 이탈 등의 원인으로 소실되는 경우 연마공구 자체가 수명을 다하여 사용하지 못하게 된다는 문제가 있다. 또한, 세그먼트 타입의 단층의 세그먼트 공구는 공구의 수명이 절삭 및 연마의 조건에 따라 일정하지 않으며, 절삭이 균일하게 되지 못하는 문제점이 있다.
However, in the case of an abrasive tool having a single layer of abrasive grains by such general electrodeposition or fusion, the abrasive tool itself has a lifespan when one layer of abrasive grains directly involved in the processing of the workpiece is lost due to breakage or separation during processing. There is a problem that can not be used to. In addition, the segment type single layer segment tool has a problem that the tool life is not constant according to the conditions of cutting and polishing, and the cutting is not uniform.

본 발명은 상술한 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 단층의 연마지립 층을 여러층 적층하여 복수 층의 연마지립 층을 형성되게 함으로써, 최외각층의 연마지립이 파손, 이탈된 경우 그 하부층에 위치하는 연마지립이 그 역할을 대신할 수 있도록 하여 연마 및 절삭 공구의 수명을 연장시키는데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to stack a plurality of abrasive grain layers of a single layer to form a plurality of abrasive grain layers, whereby the abrasive grains of the outermost layer are broken and dislodged. In this case, the abrasive grains located in the lower layer may be substituted for the role thereof, thereby extending the life of the polishing and cutting tools.

또한, 본 발명은 연마공구의 절삭, 연마 성능 등 가공 효율을 향상시키는 것을 또 다른 목적으로 한다.
Another object of the present invention is to improve processing efficiency, such as cutting and polishing performance of an abrasive tool.

The polishing layer may comprise a polishing portion bonded by a bonding material and a shank to which the polishing portion is attached.

이와 같이 베이스(110) 상에 연마지립(120)이 부착된 연마층이 복수 층으로 적층되어 구성됨으로써, 연마공구에 의한 피삭재의 연마 또는 절삭 등의 가공 중 최외곽 층의 연마지립이 소실 되더라도 그 하부 층의 연마지립에 의해 가공을 계속 수행할 수 있으므로 단층의 연마지립이 부착된 연마공구에 비해 오래 사용할 수 있고, 연마, 절삭 등의 가공 효율도 향상시킬 수 있다.As such, the abrasive layer having the abrasive grains 120 attached to the base 110 is laminated in a plurality of layers, so that even when the abrasive grains of the outermost layer are lost during the grinding or cutting of the workpiece by the abrasive tool, Processing can be continued by the abrasive grains of the lower layer, so that it can be used longer than the abrasive tool with a single abrasive grain, and the processing efficiency such as polishing and cutting can be improved.

베이스(110)는 그 상면에 연마지립(120)이 부착될 수 있도록 하는 기재 역할을 수행하는 것으로, 금속 메쉬망으로 이루어질 수 있다.The base 110 serves as a substrate for attaching the abrasive grain 120 to the upper surface thereof, and may be formed of a metal mesh network.

That is, as illustrated in FIG. 4, the abrasive grains have a regular or irregular continuous or discontinuous pattern by means of a masking 150 or the like on the base 110, and then by electrodeposition, fusion, and resin bonding. The abrasive grains may be attached to the base to form an abrasive layer.

이에 의해, 세그먼트 타입의 연마공구가 다이아몬드가 무질서하게 배열되어 세그먼트마다 연마 및 절삭 성능의 편차를 갖는 것과 달리 본 발명에 따른 연마 및 절삭 공구는 균일한 연마 및 절삭 성능을 가지면서 또한 가공 효율을 향상 시킬 수 있다.As a result, unlike the segment type abrasive tool, the diamonds are arranged randomly so that the grinding and cutting performance of each segment is different, the grinding and cutting tool according to the present invention has uniform polishing and cutting performance and also improves the processing efficiency. You can.

또한, 이 마스킹 등의 방법에 의한 패턴화를 통해 베이스(110) 상에 부착되는 연마지립(120)을 일정한 개수의 연마지립이 일정한 간격을 갖도록 배열되게 배치 함으로써, 연마공구의 연마 및 절삭 가공 효율을 최대화 시킬 수 있을 것이다.In addition, by arranging the abrasive grains 120 to be attached on the base 110 through patterning by masking or the like, such that a predetermined number of abrasive grains are arranged at regular intervals, thereby improving the polishing and cutting efficiency of the abrasive tool.

연마부(100)는 베이스(110) 상에 연마지립(120)이 부착된 연마층이 복수 층으로 적층되고 결합되어 구성된다. 즉 베이스 상에 연마지립이 전착된 전착 연마층이 복수 층으로 적층되거나, 베이스 상에 연마지립이 융착된 융착 연마층이 복수 층으로 적층되거나, 베이스 상에 연마지립이 수지 접합된 수지 접합 연마층이 복수 층으로 적층되어 구성될 수 있다. The polishing unit 100 is configured by stacking and bonding a plurality of polishing layers having abrasive grains 120 attached on the base 110 in a plurality of layers. That is, the electrodeposited abrasive layer in which abrasive grains are electrodeposited on the base is laminated in plural layers, the fused abrasive layer in which abrasive grains are fused on the base is laminated in plural layers, or the resin bonded abrasive layer in which abrasive grains are resin bonded on the base. It can be laminated | stacked in multiple layers.
