본 고안은 아람담 인조 연마재와 석류석의 천연 연마재의 혼합 재질로된 그라인더의 원형 연마석에 있어서, 입도가 70-150멧쉬로된 혼합 연마재로 원형 연마석을 구성하되 원형 주연부에 일정한 등간격(等間隔)으로 반달형의 요입부를 형성하고 이 요입부에 30-60 멧쉬의 혼합 연마재를 적층하여서된 이중 입도의 연마석에 관한 것이다.The present invention is a circular abrasive stone of a grinder composed of a mixture of Aramdam artificial abrasives and natural garnishes of garnet, and the circular abrasives are composed of a mixed abrasive having a particle size of 70-150 mesh, but have a constant equal interval on the circular periphery. The present invention relates to a double grain size abrasive stone formed by forming a half-moon-shaped recessed portion and laminating a mixed abrasive of 30-60 mesh on the recessed portion.
종래의 그라인더 연마석은 연마재의 종류에 상관없이 단일 입도의 연마재로 연마석을 구성하였기 때문에 가령 피연마 물질을 연마할때 먼저 거친 연마석에 의하여 연마한 다음 거친 연마자욱을 별도의 고은 연마석으로 연마하여 광택가공 하였으나 거친 연마 자욱이 깊어서 광택 가공에 많은 품이드는 문제점이 있었다.Conventional grinder abrasives consist of abrasive grains of a single particle size regardless of the type of abrasives. For example, when polishing a polished material, the abrasive grains are first polished by coarse abrasive stones, and then the coarse abrasive grains are polished by a separate high silver abrasive stone. However, because of the deep abrasive abrasives, there were problems with many molds for polishing.
본 고안은 종래의 이러한 문제점을 시정하기 위하여 아람담의 인조연마재와 석류석의 천연 연마재를 20 : 80 의 중량비로 혼합한 혼합연마재로 그라인더의 연마석을 구성함에 있어, 상기 혼합 연마재중 70-150 멧쉬의 혼합연마재로 연마석을 원형으로 형성하되 일정간격보다 반달형으로 요입되게 형성하고 이 요입부에는 상기 혼합연마재중 30-60멧쉬의 혼합연마재로 적층하여 전체가 원형의 연마석을 구성함으로서 연마석의 회전원주에서 연마석의 거친면과 고은면이 번갈아 피연삭 물질을 연삭하게되어서 거친연삭면에 의하여 용이하게 연삭되는 동시 고은 연삭면에 의하여 거칠게 연삭된 면을 평활하게 가공하여서 보다 편리하고 능률적으로 연삭작업을 할수있게 안출한 것으로 이를 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to construct the abrasive stone of the grinder with a mixed abrasive material in which the artificial abrasive of Aramdam and the natural abrasive of garnet are mixed in a weight ratio of 20:80 in order to correct these problems of the prior art, 70-150 mesh of the mixed abrasive Abrasive stone is formed in a circular shape with a mixed abrasive material, but is formed in a half moon shape rather than a predetermined interval, and the recessed part is laminated with a mixed abrasive material of 30-60 mesh of the mixed abrasive material to form a circular abrasive stone as a whole, thereby grinding the abrasive stone in the circumference of the abrasive stone The rough and hard surface of the grinding surface are alternately ground to easily grind the material to be polished by the rough grinding surface. If this is described in detail by the drawings as follows.
그라인더의 원형 연마석(1)에 있어서, 아람담의 인조 연마재와 석류석의 천연 연마재를 20 : 80의 중량비로 혼합한 혼합 연마재중 70-150 멧쉬의 가는 입자로된 혼합 연마재층(2)으로 연마석(1)을 공지의 점결재에 의하여 적층 형성하되, 원주위의 일정한 등간격마다 수개의 같은 크기의 반달형의 요입부(3)을 형성하고 상기 혼합연마재중 30-60 멧쉬의 거친 입자로도니 혼합 연마재층(4)을 요입부(3)에 공지의 점결재에 의하여 적층하여서 원형의 이중 입도의 연마석을 구성하고 연마석(1)의 한쪽면에 공지의 보강용 유리섬유층(5)을 적층 형성하여서 된 것이다.In the circular abrasive stone (1) of the grinder, the abrasive stone (2) is composed of a mixed abrasive layer (2) of 70-150 mesh fine particles in the mixed abrasive material of Aramdam artificial abrasive and garnet natural abrasive in a weight ratio of 20:80. 1) is laminated by a known caking material, and several half-sized recesses 3 of the same size are formed at regular equal intervals around the circumference, and the mixed abrasive is made of coarse particles of 30-60 mesh in the mixed abrasive material. The layer 4 is laminated on the recess 3 by a known caking material to form a circular double grained abrasive stone, and by laminating a known reinforcing glass fiber layer 5 on one side of the abrasive stone 1 will be.

이와 같이된 본 고안은 아람담 인조 연마재와 석류석의 천연 염마재의 혼합연마재중 70-150멧쉬의 고은 입자로된 혼합 연마재층(2)으로 연마석(1)의 기본체를 형성하되 원주위에 일정한 등간격마다 수개의 같은 크기의 반달형의 요입부(3)를 형성하고 이 요입부(3)에 30-60멧쉬의 거친 입자로된 혼합 연마재층(4)을 적층하여 원형의 이중 입도의 연마석을 구성하였기 때문에 고은 입자의 연마재층(2)과 거친 입자의 혼합 연마재층(4)의 밀도가 서로 달라도 이들 연마재층(2)(4)이 원주의 등간격으로 무개중심의 평형을 이루고 있어, 연마석(1)의 회전시에 떨림이 없이 조용하게 회전되고 또한 연마석의 회전원주에서 고은 입자의 혼합 연마재층(2)과 거친 입자의 혼합 연마재층(4)이 번갈아 회전되기 때문에 어떤 피연삭 물질을 연삭할 때 거친 혼합 연마재층(4)에 의하여 거칠면서도 비교적 신속하고 능률적으로 용이하게 연삭되는 동시 거칠게 연삭된 연삭자욱이 고은입자의 연마재층(2)에 의하여 평활하게 가공할수 있고 연마 자욱이 깊지 않아 피연삭물의 연삭면을 용이하게 광택가공 할수 있으며 보강용 유리섬유층(5)에 의하여 연마석(1)의 강도가 전체적으로 보강됨으로 적층된 연마재층이 피연삭물질과의 충격이나 마찰등에 파쇄되는 일이없이 보다 안전하고 편리하게 사용할수 있는 효과가 있다.In this way, the present invention is a mixed abrasive layer (2) made of 70-150 mesh high silver particles in the mixed abrasive material of Aramdam artificial abrasive and garnet natural brine to form the basic body of abrasive stone (1), but at regular intervals around A half moon-shaped recessed part 3 of the same size was formed each time, and a mixed abrasive layer 4 made of coarse particles of 30-60 mesh was laminated on the recessed part 3 to form a circular double grained abrasive stone. Therefore, even when the abrasive layer 2 of the high silver particles and the mixed abrasive layer 4 of the coarse particles are different from each other, the abrasive layers 2 and 4 are equilibrated in an uneven center at equal intervals of the circumference. In the rotation of), it is quietly rotated without shaking, and the mixed abrasive layer 2 of coarse particles and the mixed abrasive layer 4 of coarse particles are alternately rotated in the rotational circumference of the abrasive stone so that when grinding any abrasive material By mixed abrasive layer (4) Simultaneously rough grinding, which is easy to grind, yet relatively quick and efficient, can be smoothly processed by the abrasive layer (2) of silver particles, and the grinding surface of the workpiece can be easily polished due to the lack of deep abrasives. Since the strength of the abrasive stone 1 is reinforced by the glass fiber layer 5 for the whole, the laminated abrasive layer can be used more safely and conveniently without being crushed by impact or friction with the material to be ground.
