본 고안은 냉각수가 공급되는 절단기에 관한 것으로서, 보다 상세하게는 절단기 내부로 냉각수가 공급되어지게 유로를 형성하여 유로를 통해 냉각수가 다이아몬드 커터로 공급되어짐으로 작동시 다이아몬드 커터로부터 발생되는 고열 발생을 억제할 수 있어 기기의 파손 방지는 물론 작업의 편리성 및 안전성을 향상시킬 수 있는 절단기에 관한 것이다.The present invention relates to a cutter to which the coolant is supplied, and more particularly, to form a flow path for supplying the coolant to the inside of the cutter and to suppress the generation of high heat generated from the diamond cutter during operation since the coolant is supplied to the diamond cutter through the flow path. The present invention relates to a cutting machine capable of preventing damage to the machine and improving convenience and safety of work.

일반적으로 길이가 긴 금속, 석재, 목재, 콘크리트, 합성수지와 같은 소재의 절단작업은 쇠톱과 같은 수동절단기를 사용하거나, 또는 모터를 이용한 디스크형 회전톱날과 같은 전동절단기를 이용한 절단기가 사용되어진다.In general, the cutting of long materials such as metal, stone, wood, concrete, synthetic resin using a manual cutter such as a hacksaw, or a motorized cutter such as a disk-type saw blade using a motor.

이와 같은 절단기에는 석재, 금속, 콘크리트와 같은 취성이 있는 절삭물(피가공물)을 절단하기 위해서는 절삭물보다 높은 경도를 갖는 연마재가 요구되어지는데, 이때 연마재로 통상 다이아몬드 커터(Diamond Cutter)가 사용되어진다.In order to cut brittle cuttings (workpieces) such as stone, metal, and concrete, such a cutting machine requires an abrasive having a higher hardness than the cuttings. In this case, a diamond cutter is usually used as an abrasive. Lose.

상기 다이아몬드 커터는 절단기에 장착되어지며, 금속판부재의 끝단부 외주면에 절삭물을 연마하면서 절삭하도록 하는 다이아몬드 절삭부를 구비하여 절삭물을 절삭하면서 절삭물을 일정 간격으로 가공한다.The diamond cutter is mounted to the cutter, and has a diamond cutting portion for cutting while cutting the cutting on the outer peripheral surface of the end of the metal plate member to process the cutting at regular intervals while cutting the cutting.

그리고, 상기 다이아몬드 커터의 중심부분에는 장착홀이 형성되어져서 절단기의 회전축부재를 장착홀에 삽입하여 볼트 및 너트 등을 사용하여 고정 설치하도록 하고, 회전축부재로 다이아몬드 커터를 회전시켜서 절삭물을 가동하도록 한다.In addition, a mounting hole is formed in the center portion of the diamond cutter to insert the rotary shaft member of the cutter into the mounting hole so as to be fixed by using a bolt and nut, and to rotate the diamond cutter with the rotary shaft member to operate the cutting object. do.

그런데, 상기와 같은 종래의 다이아몬드 커터는 절삭물을 장시간에 걸쳐서 가공하다 보면, 금속판부재에 고온의 열이 축적되어지면서 고속 회전시에 금속판부재가 미세하게 흔들리게 되고, 그로 인하여 다이아몬드 절삭부가 떨리면서 절삭물을 비정상적으로 절단하면서 발생하는 마찰로 인하여 부하가 커지게 됨으로 결국에는 금속판부재가 찢어지게 되는 문제점과 금속판부재의 고열로 인해 작업자가 작업시에 금속판부재에 신체 일부가 닿게 되면 화상을 입게 되는 문제가 있다.However, in the conventional diamond cutter as described above, when the workpiece is processed for a long time, the metal plate member is finely shaken at high speed while high temperature heat is accumulated in the metal plate member, thereby cutting the diamond cutting part with shaking. The friction caused by cutting the water abnormally increases the load, which eventually causes the metal plate member to tear and the high temperature of the metal plate member causes burns when the body part touches the metal plate member during operation. There is.

따라서, 본 고안은 상기한 문제를 해결하기 위하여 안출한 것으로 절단기를 장시간에 걸쳐 사용하여도 다이아몬드 커터에 고온의 열이 발생되지 않도록 함으로 다이아몬드 커터에 발생되는 부하를 방지하여 절삭물의 정확한 절단을 이룰 수 있어 제품성을 향상시킬 수 있음은 물론 고온의 열로 인한 화상을 입게 되는 등의 안전사고를 방지할 수 있도록 한 냉각수가 공급되는 절단기를 제공하고자 하는 데 그 목적이 있다.Therefore, the present invention has been devised to solve the above-mentioned problem, so that even if the cutter is used for a long time, high temperature heat is not generated in the diamond cutter, thereby preventing the load generated on the diamond cutter, thereby achieving accurate cutting of the cutting. The purpose of the present invention is to provide a cutting machine to which the coolant is supplied so that the productability can be improved and the safety accident such as being burned by high temperature heat can be prevented.

상기한 목적을 달성하기 위한 본 고안은 절단기의 회전부재와 손잡이에 서로 연통되어지게 유로를 형성하여 이 유로를 통해 냉각수 공급호스로부터 공급되는 냉각수가 유입되도록 하며, 상기 유로를 통해 공급되는 냉각수가 다이아몬드 커터에 분출될 수 있도록 다이아몬드 커터를 회전부재에 고정시키기 위한 장착부재에 냉각수 분사구가 형성되어짐을 특징으로 하는 냉각수가 공급되는 절단기를 제공함에 있는 것이다.The present invention for achieving the above object is to form a flow path to be in communication with each other in the rotary member and the handle of the cutter so that the cooling water supplied from the cooling water supply hose through this flow path, the cooling water supplied through the flow path diamond It is to provide a cutter to which the coolant is supplied, characterized in that the coolant injection port is formed in the mounting member for fixing the diamond cutter to the rotating member so as to be ejected to the cutter.
