Abstract

A hole-treatment tool applied with poly crystal diamond is provided to improve durability by integrally coupling a poly crystal diamond tip to a front end of a cutting unit to prevent the poly crystal diamond tip from being separated. A hole-treatment tool applied with poly crystal diamond includes a shank, a cutting unit(20), a vertical assembly groove(30), and a poly crystal diamond tip(40). The cutting unit has a chip discharging groove(22) along a lengthwise direction, and the poly crystal diamond tip is coupled to a cutting blade which is inclined from a center toward both sides. The vertical assembly groove is formed at a front end of the cutting unit in a straight line from the center along a direction of cutting rotation of both cutting blades. The poly crystal diamond tip includes edges(43,43') inclined corresponding to the cutting blade at both sides of a central tip blade unit(42).

본 발명은 가공물의 각종 구멍을 가공하기 위한 홀가공공구에 관한 것으로, 좀더 상세하게는 내마모성 및 절삭성을 극대화하기 위해 절삭부에 인조다이아몬드 팁을 결합 구성한 인조다이아몬드 팁을 적용한 홀가공공구의 개량에 관한 것이다.The present invention relates to a hole processing tool for processing various holes of the workpiece, and more particularly, to an improvement of the hole processing tool to which the artificial diamond tip is configured to combine the artificial diamond tip in the cutting portion to maximize the wear resistance and cutting properties will be.

일반적으로 가공물에 구멍을 가공하거나 상기 구멍에 추가적인 가공을 행하기 위해 드릴, 리머, 탭드릴 등의 공구를 사용하게 된다.Generally, a tool such as a drill, a reamer, a tap drill, or the like is used to process a hole in a workpiece or to further process the hole.

상기한 각종 구멍 가공을 위한 공구를 이하 '홀가공공구'라 칭한다.The above-mentioned tools for processing various holes are hereinafter referred to as "hole processing tools".

이러한 홀가공공구, 일 례로 드릴공구는 생크와, 가공물을 절삭하기 위한 절삭날과 절삭된 칩을 배출하기 위한 칩배출홈을 갖는 절삭부로 구성되어 있다.Such a hole processing tool, for example, a drill tool is composed of a shank, a cutting portion having a cutting edge for cutting a workpiece and a chip discharge groove for discharging the cut chips.

이러한 드릴공구는 상기 생크를 드릴머신 등과 같은 가공장치에 장착하여 회전 및 하강 구동시키면서 가공물에 일정 구멍을 절삭 가공하게 되는 것이다.Such a drill tool is to mount the shank to a processing device such as a drill machine to cut a certain hole in the workpiece while rotating and driving down.

그런데 상기한 종래의 드릴공구는 선단 절삭날의 경도가 약해 가공물의 가공작업에 의해 쉽게 마모됨은 물론 손상되는 문제점이 있었다.However, the conventional drill tool has a problem in that the hardness of the cutting edge is weak and is easily worn and damaged by the processing of the workpiece.

이러한 문제를 해결하고자 드릴공구의 절삭날에 인조다이아몬드 팁을 결합 구성하는 기술이 개시된 바 있는데, 이는 도 1 및 도 2에 도시된 바와 같이, 절삭부(2)의 선단에 중앙에서 양측으로 경사지게 형성된 절삭날(3)의 외측단으로 홈부(4)를 형성하여 인조다이아몬드 팁(5)을 결합 구성하도록 한 것이다.In order to solve this problem, a technique of coupling an artificial diamond tip to a cutting edge of a drill tool has been disclosed. As shown in FIGS. 1 and 2, the tip of the cutting part 2 is formed to be inclined from the center to both sides. The groove portion 4 is formed at the outer end of the cutting edge 3 so that the artificial diamond tip 5 is combined.

이는 상기 인조다이아몬드 팁(5)에 의해 가공물의 가공에 있어 내마모성이 우수하여 사용수명을 장구히하게 됨은 물론 절삭성이 우수하여 가공효율을 극대화하는 잇점을 제공하였다.This artificial diamond tip (5) has the advantage of excellent wear resistance in the processing of the workpiece, as well as long service life and excellent cutting efficiency to maximize the processing efficiency.

그러나 상기한 종래의 드릴공구는 인조다이아몬드 팁(5)이 절삭날(3)의 중앙부분이 아닌 외측단으로 결합되기 때문에 인조다이아몬드 팁이 결합되지 않은 절삭날의 중앙부분은 여전히 마모가 쉽게 되는 문제를 갖고 있었다.However, in the conventional drill tool described above, since the artificial diamond tip 5 is coupled to the outer end rather than the center portion of the cutting edge 3, the center portion of the cutting edge to which the artificial diamond tip is not coupled is still easily worn. Had.

또한, 상기 인조다이아몬드 팁(5)이 절삭날의 외측단으로 결합되어 있기 때 문에 절삭과정에서 가해지는 회전 방향의 응력에 의해 팁이 쉽게 분리, 이탈되어 손상되는 문제를 갖고 있었다.In addition, since the artificial diamond tip 5 is coupled to the outer end of the cutting edge, the tip is easily separated and detached and damaged by the stress in the rotational direction applied in the cutting process.

본 발명은 상기한 종래 기술이 갖는 제반 문제점을 해결하고자 안출된 것으로서, 절삭부의 선단에 중심에서 양측의 절삭날 부분으로 일직선상에 인조다이아몬드 팁을 일체로 결합하므로서 내마모성, 절삭성 및 정밀가공을 우수하게 제공함은 물론 인조다이아몬드 팁의 분리, 이탈우려를 방지하여 사용수명을 장구히 하도록 하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, by combining the artificial diamond tip in a straight line from the center of the cutting portion to the cutting edge portion of both sides in a straight line to excellent wear resistance, cutting properties and precision processing In addition to the purpose of providing a long life by preventing the separation and separation of artificial diamond tips.
