도 1은 본 발명에 따른 무화 절삭유 공급장치의 하나의 실시예의 개략도, 및1 is a schematic view of one embodiment of an atomizing coolant supply device according to the present invention, and

도 2는 본 발명에 따른 무화 절삭유 공급장치의 다른 하나의 실시예의 개략도이다.2 is a schematic view of another embodiment of the atomizing coolant supply device according to the present invention.

본 발명은 무화 절삭유 공급장치에 관한 것으로, 보다 상세하게는, 피가공물에 절삭유를 무화 상태로 공급하는 무화 절삭유 공급장치에 관한 것이다.The present invention relates to an atomizing cutting oil supply device, and more particularly, to an atomizing cutting oil supply device for supplying cutting oil to a workpiece in an atomized state.

절삭유는 절삭가공 때 공구의 날끝과 피가공물 사이에 부어 넣어 발열 등에 의한 장애를 방지하고, 가공능률이나 정밀도를 좋게 하며, 공구의 수명을 연장시키기 위해 사용하는 기름이다.Cutting oil is oil used to pour between the cutting edge of the tool and the workpiece during cutting to prevent obstacles due to heat generation, to improve processing efficiency and precision, and to extend the life of the tool.

그런데, 절삭유를 액체 상태로 연속적으로 붓게 되면 그 소모량이 너무 많게 되고, 한번 사용된 절삭유를 리사이클링한다고 해도 그 질이 떨어져 절삭유의 기능을 제대로 수행할 수 없는 문제가 있었다.However, when the cutting oil is continuously poured into the liquid state, the consumption thereof becomes too much, and even if the used cutting oil is recycled, the quality thereof is deteriorated, so that the function of the cutting oil cannot be performed properly.

그래서, 근래에 무화 절삭유 공급장치가 개발되었는데, 절삭유 공급장치는, 절삭유 무화탱크에서 생성된 무화 절삭유를 절삭유 무화탱크에 연결된 무화 절삭유 공급라인을 통해 피가공물의 절삭가공부위에 분사하도록 되어 있는 장치로서, 절삭유의 소모량을 획기적으로 줄일 수 있는 장치이다.Therefore, in recent years, the atomizing coolant supply device has been developed. The coolant supply device is a device which is configured to spray atomizing coolant generated from the coolant atomizing tank to the cutting part of the workpiece through the atomizing coolant supply line connected to the coolant atomizing tank. It is a device that can drastically reduce the consumption of cutting oil.

한편, 절삭가공하고자 하는 형상이 깊이가 있는 구멍인 경우에 드릴을 사용하게 되는데, 절삭가공하고자 하는 구멍의 깊이가 얕은 경우에는 드릴의 주위에 무화 절삭유 공급라인과 연결된 무화 절삭유 분사노즐을 설치하여 외부에서 구멍을 향해 무화 절삭유를 분사하고, 절삭가공하고자 하는 구멍의 깊이가 깊은 경우에는 드릴의 내부에 무화 절삭유 공급라인과 연결된 무화 절삭유 분사노즐을 드릴의 길이방향으로 관통하도록 설치하여 드릴의 말단부에서 그에 대향하는 구멍의 막힌 부분을 향해 무화 절삭유를 분사하도록 되어 있다.On the other hand, when the shape to be cut is a hole having a depth, a drill is used. When the depth of the hole to be cut is shallow, an external atomizing coolant injection nozzle connected to the atomizing coolant supply line is installed around the drill. Spray the atomizing coolant toward the hole in the hole, and when the depth of the hole to be cut is deep, install the atomizing coolant spray nozzle connected to the atomizing coolant supply line in the drill in the longitudinal direction of the drill. The atomizing cutting oil is sprayed toward the blocked portion of the opposing hole.

이렇게 드릴을 사용하여 깊이가 있는 구멍을 절삭가공하는 경우, 드릴의 말단부와 구멍의 막힌 부분 사이에 뿐만 아니라 드릴의 외주면과 구멍의 측벽 사이에도 고열이 발생하게 된다.In this way, when a deep hole is cut using a drill, high heat is generated not only between the distal end of the drill and the blocked portion of the hole, but also between the outer circumferential surface of the drill and the side wall of the hole.

그러나, 절삭가공하고자 하는 구멍의 깊이가 얕은 경우에 드릴의 주위에서 구멍을 향해 무화 절삭유를 분사하게 되면, 비산되는 무화 절삭유가 구멍 내로 충분히 유입되지 못하므로 드릴의 말단부와 구멍의 막힌 부분 사이 및 드릴의 외주면과 측벽과의 사이에 고열이 발생하게 되어 가공능률이나 정밀도가 저하되고 공구의 수명이 단축되는 문제가 있다. 또한, 절삭가공하고자 하는 구멍의 깊이가 깊은 경우에 드릴의 말단부에서 그에 대향하는 구멍의 막힌 부분을 향해 무화 절삭유를 분사하게 되면, 무화 절삭유가 구멍의 막힌 부분에 부딪힌 후 드릴 날의 나선형 홈을 따라 위로 상승하게 되므로 무화 절삭유가 드릴의 말단부와 구멍의 막힌 부분 사이에는 고열이 발생하지 않지만 드릴의 외주면과 측벽과의 사이에 고열이 발생하게 되어 역시 가공능률이나 정밀도가 저하되고 공구의 수명이 단축되는 문제가 있다.However, if atomizing coolant is sprayed from the periphery of the drill toward the hole when the depth of the hole to be cut is shallow, the scattering atomizing coolant is not sufficiently introduced into the hole, so that between the drill end and the block of the hole and the drill The high heat is generated between the outer circumferential surface and the side wall, which causes a problem that the machining efficiency or precision is lowered and the tool life is shortened. In addition, when the depth of the hole to be cut is deep, when atomizing coolant is injected from the distal end of the drill toward the blocked portion of the hole facing the hole, the atomizing cutting oil hits the blocked portion of the hole and then along the spiral groove of the drill blade. As it rises upward, the atomizing coolant does not generate high heat between the end of the drill and the blocked portion of the hole, but high heat is generated between the outer circumferential surface of the drill and the side wall, which reduces machining efficiency or precision and shortens tool life. there is a problem.

본 발명은 상기한 문제점을 해결하기 위한 것으로, 무화 절삭유와 액체 절삭유를 선택적으로 분사할 수 있도록 구성된 무화 절삭유 공급장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide an atomizing cutting oil supply device configured to selectively spray atomizing cutting oil and liquid cutting oil.

However, the present invention also provides a separate coolant storage tank to supply liquid coolant from the cutting fluid storage tank to the liquid coolant supply line. You will find that you are in the category of

전술한 바와 같이, 본 발명의 개선된 무화 절삭유 공급장치에 의하면, 무화 절삭유와 액체 절삭유를 선택적으로 분사할 수 있도록 구성되어 있으므로, 드릴을 사용하여 깊이가 있는 구멍을 절삭가공하는 경우, 드릴의 말단부와 구멍의 막힌 부분 사이 및 드릴의 외주면과 구멍의 측벽 사이에 고열이 발생하지 않게 되어, 절삭유 소모량을 줄일 수 있으면서도 가공능률이나 정밀도의 저하가 방지되고 공구 수명의 단축이 방지되는 효과가 있다.As described above, according to the improved atomizing coolant supply device of the present invention, the atomizing coolant and the liquid coolant can be selectively sprayed, so that the end portion of the drill when cutting a hole having a depth using the drill And high heat is not generated between the blocked portion of the hole and between the outer circumferential surface of the drill and the side wall of the hole, while reducing the consumption of cutting oil, it is possible to prevent a decrease in machining efficiency or precision and to shorten the tool life.
