Description

절삭휠 표면의 마킹방법{A Method for Forming a Mark on the Surface of Cutting Wheel Shank}A Method for Forming a Mark on the Surface of Cutting Wheel Shank}

본 발명은 석재나 금속 등과 같은 경질재료(이하, `피삭체'라 한다)를 절단하기 위한 절삭휠(cutting wheel)의 제조에 관한 것으로서, 보다 상세하게는 절삭휠의 생크(shank)의 표면에 소결을 통하여 문자나 로고 등(이하, `마크'라 한다)을 마킹하는 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the manufacture of a cutting wheel for cutting hard materials such as stone or metal, hereinafter referred to as a " workpiece ", and more particularly to the surface of a shank of a cutting wheel. It relates to a method of marking letters, logos, etc. (hereinafter referred to as 'mark') through sintering.

절삭휠은 피삭체를 절단 또는 절삭하는 과정에서 이용되는 원판 형상의 회전체로서, 도1에 도시된 바와 같이, 금속재질로 제작된 생크(shank)(11)와, 이 생크(11)의 둘레를 따라 형성된 다수개의 절삭팁(tip segment)(12)을 포함하여 구성된다. 상기 절삭팁(12)은 다이아몬드 입자를 금속분말에 혼합하여 고온 고압으로 소결하여 제조된다.The cutting wheel is a disk-shaped rotating body used in the process of cutting or cutting a workpiece. As shown in FIG. 1, a shank 11 made of metal and a circumference of the shank 11 are provided. It is configured to include a plurality of tip segments (12) formed along the. The cutting tip 12 is manufactured by mixing diamond particles with a metal powder and sintering at high temperature and high pressure.

이러한 절삭휠은 고속으로 회전하면서 피삭체를 절삭 또는 연마하기 때문에, 종래부터 생크 표면에 마크(mark)를 넣는 일은 용이하지 않았다. 예컨대, 종래에는 생크 표면에 스티커(sticker)를 붙인다던가, 아니면 마크를 페인트 등으로 써넣거나 또는 표면을 각인하는 방법이 전부였다. 그러나, 이러한 방법들에 의해 형성된 마크들은 절삭휠의 고속 회전에 의한 마모와 함께 바로 없어져 버리는 것은 물론이다. 하지만, 최근 절삭휠의 고급화와 더불어 생크 표면에 마크를 표시하는 일은 더욱 절실히 요구되고 있다.Since such a cutting wheel cuts or polishes a workpiece while rotating at a high speed, it has not been easy to put a mark on the shank surface. For example, conventionally, all have been a method of affixing a sticker on the shank surface, writing a mark in paint, or marking the surface. However, the marks formed by these methods are of course immediately lost with the wear caused by the high speed rotation of the cutting wheel. However, with the recent advancement of cutting wheels, marking marks on the shank surface is more urgently required.

본 발명은 상기한 요구에 부응하고자 제안된 것으로써, 그 목적은 절삭휠 생크의 표면에 소결을 통하여 마크를 나타냄으로써, 절삭휠을 다 사용할 때까지 상기 마크를 유지하고 절삭휠의 마모와 함께 소모되도록 하는 절삭휠 표면의 마크방법을 제공하는 데 있다.The present invention has been proposed to meet the above requirements, the object of which is to mark the surface of the cutting wheel shank through sintering, thereby maintaining the mark until the cutting wheel is used up and wasting with the wear of the cutting wheel. It is to provide a method of marking the surface of the cutting wheel to be.

상기 목적 달성을 위한 본 발명에 따른 마킹방법은, 절삭휠 표면에 마크를 형성하는 방법에 있어서, 절삭휠 표면의 마킹할 부위를 동도금한 후, 마크조각 및 상기 절삭휠의 절삭팁에 대응하는 부위가 음각 또는 양각으로 형성된 몰드에 상기 마크조각을 위치시키고, 상기 절삭휠을 올려놓고 가열 가압하는 것을 특징으로 한다. In the marking method according to the present invention for achieving the above object, in the method for forming a mark on the surface of the cutting wheel, after copper plating a portion to be marked on the surface of the cutting wheel, the portion corresponding to the mark piece and the cutting tip of the cutting wheel The mark is placed in a mold formed in an intaglio or embossed, it is characterized in that the cutting wheel is put on the heating pressure.

이하, 본 발명을 도면을 통하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the drawings.

도2는 본 발명의 마킹방법에 의해 표면에 마크가 형성된 절삭휠의 외관도이다. 도2에 도시된 바와 같이, 본 발명에 의해 형성된 일정한 형상의 마크(4)는 마크의 형상이나 모양 또는 크기 등에 관계없이 생크(1)의 표면에 형성될 수 있다. 바람직하게는 상기 마크(4)는 도2의 「A-A」 단면도에도 나타난 바와 같이, 절삭휠(10')의 절삭팁(2) 단차(h)와 거의 동일한 높이를 갖도록 형성되는 것이다. 이러한 마크는 소결을 통하여 형성되는 데, 도3을 통하여 본 발명의 마킹방법을 설명한다. 2 is an external view of a cutting wheel having a mark formed on its surface by the marking method of the present invention. As shown in Fig. 2, the mark 4 of a certain shape formed by the present invention can be formed on the surface of the shank 1 regardless of the shape, shape or size of the mark. Preferably, the mark 4 is formed to have substantially the same height as the step h of the cutting tip 2 of the cutting wheel 10 ', as shown in the cross-sectional view "A-A" in FIG. Such marks are formed through sintering, and the marking method of the present invention will be described with reference to FIG.

도3은 본 발명의 마킹방법에 사용되는 몰드의 모식도이다. 몰드(3)는 도3에 나타난 바와 같이, 상, 하 금형(31, 32)과 그 사이에 여러 개의 중간 금형(33)(도3에서는 3개)으로 이루어지며, 각 금형(31, 32, 33)의 표면에는 절삭휠(10')의 절삭팁(2)의 형상에 맞는 홈(35)들이 형성되어 상기 절삭팁(2)을 수납할 수 있다. 또한, 각 금형(31, 32, 33) 표면의 마킹할 부위에는 마크조각(4)을 수납할 수 있도록 일정한 모양이나 형상이 음각 또는 양각된 홈(36)들이 형성되어 있다. 본 발명에서 상기 중간 금형(33)의 갯수나 금형의 음각홈(36)(또는 양각홈)들의 모양이나 형상은 임의로 제작 가능함은 물론이다. 3 is a schematic view of a mold used in the marking method of the present invention. The mold 3 is composed of upper and lower molds 31 and 32 and a plurality of intermediate molds 33 (three in FIG. 3) between them, as shown in FIG. The groove 35 is formed on the surface of the cutting wheel 10 ′ to accommodate the shape of the cutting tip 2 of the cutting wheel 10 ′ to accommodate the cutting tip 2. In addition, grooves 36 in which a predetermined shape or shape is engraved or embossed are formed in a portion to be marked on the surface of each mold 31, 32, 33. In the present invention, the number of the intermediate mold 33 or the shape or shape of the intaglio grooves 36 (or the embossed grooves) of the mold can be arbitrarily manufactured.

본 발명에 따른 마크방법에서는 상기 절삭휠(10')은 마크조각(41)과의 접착력이 우수하도록 적어도 마킹할 생크(1)의 표면 부위를 미리 동도금한다. 또한, 상기 마크조각(41)들은 절삭팁을 제작할 때 사용되는 분말로 성형될 수 있으나, 바람직하게는 Cu-Sn계 분말을 사용하는 것이다. 또한, 상기 마크조각들은 상기 절삭팁 단차(h)와 거의 동일한 높이를 갖도록 함이 바람직한데, 마크조각을 제작할 때는 몰드의 가열, 가압에 의한 수축은 물론 소결되는 과정에서의 수축 등을 감안할 필요가 있다. In the mark method according to the invention, the cutting wheel 10 'pre-plates at least the surface portion of the shank 1 to be marked so as to have excellent adhesion to the mark piece 41. In addition, the mark pieces 41 may be formed of a powder used when manufacturing a cutting tip, but preferably Cu-Sn-based powder. In addition, it is preferable that the mark pieces have the same height as the cutting tip step h. When manufacturing the mark pieces, it is necessary to take into account the shrinkage during the sintering process as well as shrinkage due to heating and pressing of the mold. have.

본 발명에 따른 절삭휠 표면의 마킹공정은, 상기 마크조각(41)을 절삭휠(10')의 생크(1) 표면의 마킹할 부위에 위치시킨 다음, 상기 마크조각에 대응하는 부위가 형성된 몰드(3)에 상기 절삭휠(10')을 올려놓는다. 여기서, 상기 절삭휠은 미리 절삭팁(2)이 성형되어 있다. In the marking process of the surface of the cutting wheel according to the present invention, the mark piece 41 is placed on a portion to be marked on the surface of the shank 1 of the cutting wheel 10 ', and then a mold having a portion corresponding to the mark piece is formed. The cutting wheel 10 'is placed on (3). Here, the cutting tip 2 is formed in advance on the cutting wheel.

이후, 상기 몰드(3)를 가열 가압하여 상기 마크조각(41)을 소결시키면, 절삭휠 생크 표면에는 일정한 형상이나 모양을 갖는 마크가 형성된다. 예컨대, 도2에 도시된 바와 같이, "HYOSUNG"이라는 상호 마크를 선명하고 미려하게 넣을 수 있다. 상기 절삭휠 또는 몰드에 가하는 온도나 압력은 대체로 10 ~ 100Kg/㎠의 압력 하에서 700 ~ 1000℃의 범위로 행하는 것이 바람직하다.Thereafter, when the mold 3 is heated and pressurized to sinter the mark pieces 41, a mark having a predetermined shape or shape is formed on the cutting wheel shank surface. For example, as shown in Fig. 2, the mutual mark "HYOSUNG" can be clearly and beautifully put. The temperature or pressure applied to the cutting wheel or the mold is preferably performed in the range of 700 to 1000 ° C. under a pressure of 10 to 100 Kg / cm 2.

이렇게 마크(4)가 형성된 절삭휠(10')은 통상적인 드레싱 공정(dressing process)이 행해질 수 있다. 이 드레싱 공정에서는 상기 소결과정에서 산화된 피막을 없애면서 절삭휠의 초기 절삭성을 향상시키게 된다.The cutting wheel 10 'in which the mark 4 is formed can be subjected to a conventional dressing process. In this dressing process, the initial cutting property of the cutting wheel is improved while removing the film oxidized in the sintering process.

상술한 바와 같이, 본 발명에 의하면, 절삭휠 생크의 표면에 소결을 통하여 마크를 나타냄으로써, 종래방법에 비하여 절삭휠의 표면에 훨씬 미려하고 선명한 마크를 형성할 수 있고, 이러한 마크는 절삭휠을 다 사용할 때까지 유지되어 절삭휠이 완전 마모되어도 없어지지 않기 때문에 꼭 필요한 문자나 형상 또는 기호 등을 넣는 데 매우 유용할 뿐만 아니라 절삭휠의 제품 가치를 높일 수 있는 부수적인 효과도 있다. As described above, according to the present invention, by marking the surface of the cutting wheel shank through sintering, it is possible to form a much more beautiful and clear mark on the surface of the cutting wheel as compared to the conventional method, and such marks make the cutting wheel It is not only useful for inserting necessary letters, shapes or symbols, but also a side effect of increasing the product value of the cutting wheel since it is maintained until it is used and does not disappear even if the cutting wheel is completely worn out.
