Abstract

The present invention relates to a cutting tip and a manufacturing method thereof, wherein the cutting tip is manufactured by alternately stacking a metal mixed molded body formed only of metal mixed powder between mixed molded bodies for cutting in a sintering device while stacking the mixed molded bodies for cutting in which diamond abrasive grains and metal mixed powder are mixed in multiple layers, and then sintering the same through compression and heating. Accordingly, since the metal mixed molded body is worn before the mixed molded body for cutting according to cutting of a workpiece, the diamond abrasive grains mixed with the mixed molded body for cutting can be protected from heat. Therefore, not only can the life span of the cutting tip be extended, but also the work efficiency can be improved due to enhancement of cutting force. Furthermore, the manufacturing cost for mass production can be lowered.

When the mixture for the metal powder layer and the metal powder layer are alternately stacked, first, the amount of the mixture for the cutting layer and the metal powder layer is measured by a balance, and then the measured amount is alternately put and stacked to produce a single cutting. It takes a lot of time to manufacture the tip, and there is a disadvantage that a lot of workers are required to shorten the time, which in turn increases the manufacturing cost.

이하에서, 상기한 본 발명에 따른 절삭용 팁의 제조방법을 첨부된 도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, a method for manufacturing a cutting tip according to the present invention will be described in detail with reference to the accompanying drawings.

먼저, 상기한 본 발명에 따른 절삭용 팁의 제조방법에서 외측절삭용 혼합물 제조단계(S110)는 절삭용 팁으로 제조시 가장 외측에 구성되어 피삭재 물을 절삭할 때 부하가 가장 많이 걸리는 부분으로 다이아몬드 지립과 금속혼합분말을 혼합하여 외측절삭용 혼합물을 제조하는 단계이다.First, in the manufacturing method of the cutting tip according to the present invention, the outer cutting mixture manufacturing step (S110) is composed of the outermost part when manufacturing as a cutting tip, and the diamond is the part that has the most load when cutting the workpiece. It is a step of mixing the abrasive grains and the metal mixed powder to prepare a mixture for outer cutting.

여기서, 상기한 외측절삭용 혼합물 제조단계(S110)에 의해 제조된 외측절삭용 혼합물에 혼합된 금속혼합분말은 철(Fe)과 구리(Cu)와 주석(Sn) 그리고 코발트(Co)로 혼합된 금속혼합분말로, 상기 다이아몬드 지립과 금속혼합분말의 혼합비율은 피삭재 물의 종류에 대응되게 절삭용 팁의 집중도를 높일 수 있도록 1:4~1:49의 비율로 혼합되어 제조된다.Here, the metal mixture powder mixed with the mixture for external cutting prepared by the above-described external cutting mixture manufacturing step (S110) is mixed with iron (Fe), copper (Cu), tin (Sn), and cobalt (Co).

Diamond abrasives are protected from heat.

또한, 상기한 내측절삭용 성형체층(230)에 혼합된 다이아몬드 지립은 외측절삭용 성형체층(210)에 혼합된 다이아몬드 지립보다 7%가 적게 혼합되므로 인해 석재 절삭시 부하가 적게 걸리게 된다.In addition, the diamond abrasive grains mixed in the molded body layer 230 for inner cutting are 7% less mixed than the diamond abrasive grains mixed in the molded body layer for outer cutting 210, so that the load on the stone is reduced.

그로 인해, 균일하게 마모될 뿐만 아니라 작업 효율을 향상시킬 수 있다.As a result, it is possible to not only wear uniformly, but also to improve work efficiency.
