본 고안은 그라인더의 연마석에 있어서 연마석을 구성하는 경도가 높은 아람담 입자층과 예리한 절결각에 의한 양호한 연삭성을 갖는 석류석 입자층을 그라인더의 중심부에서 방사상의 경사면으로 적층되게 교호로 형성하여 아람담 입자에 의한 연마석의 내구성의 향상과 석류석 입자에 의한 연마석의 연삭성을 향상시킨 그라인더 연마석에 관한 것이다.In the present invention, in the abrasive stone of the grinder, the Aramdam particle layer having high hardness and the garnet particle layer having good grindingability due to the sharp cutting angle are alternately formed to be stacked on the radial inclined surface at the center of the grinder, so that It is related with the grinder abrasive stone which improved the durability of abrasive stone by this, and improved the grinding ability of abrasive stone by garnet particle.

종래 연질 연마석의 양측면에 경질의 연마석입자를 적층하여 연마석의 양연부에 심한 마모를 어느정도 억제시키어서 고르게 연삭마모되게한 것이 있으나(일본 공개실용신안 공보 제47-6491호)이는 연마석의 마모율의 균일성을 목적으로 안출되었을뿐 연마석의 동일 조건에서 연삭성의 향상이나 내구성의 향상은 고려되어 있지 않은 미비점이 있었다.Although conventional abrasive grains are laminated on both sides of the soft abrasive stone, some of the abrasives at the edges of the abrasive stone are suppressed to some extent so that the abrasive wear is even (even in Japanese Utility Model Publication No. 47-6491). Although it was devised for the purpose of sex, the improvement of the grinding property and the durability on the same conditions of an abrasive stone did not consider, but there existed a weak point.

또한 종래의 연마석은 대부분 인조 연마재인 아람담 입자만으로 구성되어 있으나 아람담은 전량 수입품으로써 값이 고가일뿐 아니라 아람담 입자의 마모면이 미끄러워 연마석으로서의 연삭기능이 높지 못한 미비점이 있었다.In addition, the conventional abrasive stone is composed mostly of Aramdam particles, which are artificial abrasives, but Aramdam is not only expensive as a whole imported goods, but also has a weak point that the grinding function of the Aramdam particles is not high because of the slip surface of the Aramdam particles.

본 고안은 이러한 종래의 문제점을 시정하기 위하여 그라인더 연마석에 있어서 인조 연마재인 아람담 입자층과 경제적으로 저렴하면서 예리한 절결 마모성으로 인하여 절삭성이 양호한 천연산 석류석 입자층을 연마석의 중심부에서 방사상의 경사면으로 교호 적층되게 구성하므로서 연마석의 회전중심이 질량적으로 평형을 이루어 고속회전에도 떨림이 없고 아람담 입자의 높은 경도에 의하여 연마석의 내구성을 높히는 동시 석류석 입자의 예리한 절결각으로 인하여 연마석의 표면이 항상 거친면으로 유지되어 절삭성이 양호하여 종래의 연마석에 비하여 보다 경제적이면서 편리하게 각종 공작물을 연삭가공할 수 있게 안출한 것으로 이를 도면에 의하여 상세히 설명하면 다음과 같다.In order to correct this problem, the present invention allows the Aramdam particle layer, which is an artificial abrasive, and the natural garnet particle layer having good machinability due to economical inexpensive and sharp cut abrasion to be alternately laminated from the center of the abrasive stone to the radial inclined surface. As a result, the center of rotation of the abrasive is balanced by mass, so there is no trembling even in high-speed rotation, and the surface of the abrasive is always roughened due to the sharp cutting angle of the garnet, which increases the durability of the abrasive by the high hardness of Aramdam particles. It is retained to have a good cutting property to be able to grind a variety of workpieces more economically and conveniently than conventional abrasive stone to be described in detail by the drawings as follows.

그라인더의 원형 연마석에 있어서, 연마석(1)의 축공(2)을 중심으로 임의 입도로된 인조 연마재인 아람담 입자층(3)과 천연산 철반 석류석 입자층(4)을 단층폭이 1 : 4의 비율로 약 30도의 경사각을 두고 방사상으로 적층형성하여서 된 것이다.In the circular abrasive stone of the grinder, the ratio of the monolayer width of the Aramdam particle layer (3) and the natural iron plate garnet particle layer (4), which are artificial abrasives of arbitrary particle size, centered on the shaft hole (2) of the abrasive stone (1) is 1: 4. This was achieved by laminating radially with an inclination angle of about 30 degrees.

이와 같이된 본 고안은 각종 공작 물품의 연삭 연마가공을 위하여 그라인더의 연마석으로 사용하는 바 그라인더의 연마석에 있어서 모스씨 경도 약 12도 정도의 고가인 인조 연마재인 아람담 입자층(3)과 모스씨 경도 약 8-10도 정도의 천연산 철반 석류석 입자층(4)을 단층폭이 1 : 4의 비율로 약 30도 경사각을 두고 방사상으로 적층되게 구성하였기 때문에 연마석(1)의 축공(2)을 중심으로 아람담 입자와 석류석 입자가 질량적으로 평형을 이루어 연마석이 그라인더에 의하여 고속 회전하여도 전혀 떨림이 없고 아람담 입자층(3)과 석류석 입자층(4)의 경사각에 의하여 피연삭물질에 아람담 입자층(3)과 석류석 입자층(4)이 동시에 접촉 연마되어 연마석의 편마모를 방지하며 또한 아람담 입자층(3)이 석류석 입자층(4) 사이에서 연마석 조직에 기둥 역할을 하여 석류석 입자만으로된 그라인더 연마석에 비하여 연마석의 내마모성이 향상되고 또한 아람담 입자층(3) 사이에 비교적 넓게 분포된 석류석 입자층(4)이 예리하게 절결마모되는 석류석 입자의 특성으로 인하여 연마석의 표면이 항상 거친면을 이루게 되어서 아람담 입자로만 구성된 것에 비하여 피가공 물질의 연삭기능이 보다 높게 되어서 종래의 연마석에 비하여 보다 경제적으로 편리하게 각종 공작물을 유효하게 연삭연마할 수 있는 효과가 있따.In this way, the present invention is an Aramdam particle layer (3) and Mohss hardness, which are artificial abrasives having an Mohss hardness of about 12 degrees in the abrasive stone of the grinder, which is used as the abrasive stone of the grinder for grinding and polishing of various workpieces. Since the natural iron plate garnet particle layer 4 of about 8-10 degrees has a single layer width of 1 to 4, and is laminated radially at an inclination angle of about 30 degrees, the shaft hole 2 of the abrasive stone 1 is centered. Aramdam particles and garnet particles are equilibrated in mass so that no grinding is caused even when the abrasive stone is rotated at a high speed by the grinder. The incidence angle of the Aramdam particle layer (3) and the garnet particle layer (4) causes the Aramdam particle layer ( 3) and the garnet particle layer 4 are contact-polishing at the same time to prevent abrasive wear of the abrasive stone, and the Aramdam particle layer 3 acts as a pillar in the abrasive stone structure between the garnet particle layers 4 Compared with grinder abrasives composed only of garnet particles, the abrasive stone's abrasion resistance is improved and the surface of the abrasive stone is always rough due to the characteristics of the garnet particles in which the garnet particle layer 4 distributed relatively widely between the Aramdam particle layers 3 is sharply cut and worn. As it forms a surface, the grinding function of the material to be processed is higher than that of only Aramdam particles, so that it is possible to effectively grind various workpieces more economically and conveniently than conventional abrasive stones.
