Description

절삭유 여과장치{Cutting oil filtering device} Cutting oil filtering device

본 발명은 공작기계를 이용하여 각종 공작물을 가공할 때에 발생하는 열을 냉각시킴과 동시에 칩(CHIP), 절삭분 등의 이물질을 원활하게 배출할 목적으로 공작물의 절삭부위에 절삭유를 공급하게 되는데, 이때 상기 공작물을 가공(절삭)하면서 사용되는 절삭유의 재사용을 위하여 절삭유에 함유된 불순물을 여과하는 절삭유 여과장치에 관한 것이다.The present invention is to cool the heat generated when processing a variety of workpieces using a machine tool and at the same time to supply the cutting oil to the cutting portion of the workpiece for the purpose of smoothly discharging foreign substances such as chips (CHIP), cutting powder, In this case, the present invention relates to a cutting oil filtration device for filtering impurities contained in cutting oil for reuse of cutting oil used while processing (cutting) the workpiece.

일반적으로 공작물의 절삭 가공에 사용되는 절삭유는 공작물의 가공 중에 발생하는 칩이나 이물질을 포함하고 있기 때문에 이의 재사용을 위해서는 이물질 등을 제거한 후 순수한 절삭유만을 채집하여 재사용하게 된다.In general, the cutting oil used in the cutting of the workpiece contains chips or foreign substances generated during the processing of the workpiece, and in order to reuse them, only the pure cutting oil is collected and reused after removing the foreign substances.

통상 공작기계인 CNC 장비나 머시닝센터 등의 장비를 이용하여 공작물을 가공할 경우 다량의 칩(CHIP), 절삭분, 이물질(이하 "불순물"이라 통칭함) 등이 발생하게 되고, 이러한 절삭물의 가공시 고속가공에 따라 절삭물과 절삭공구에는 고열이 발생하게 되어 절삭공구의 사용수명을 단축하게 됨은 물론, 절삭과정에서 발생 하는 불순물은 가공과 동시에 공급되는 절삭유에 함유된 상태로 순환하는 방식으로 사용하게 된다.In general, when machining a workpiece using equipment such as a CNC machine or a machining center, which is a machine tool, a large amount of chips, chips, and foreign matters (hereinafter referred to as "impurities") are generated. The high-speed cutting of the cutting tool and the cutting tool generates high heat, which shortens the service life of the cutting tool. In addition, impurities generated during the cutting process are circulated in the state of the cutting oil supplied at the same time as the processing. Done.

이러한 절삭유는 최초에 공급할 경우는 별 문제가 발생하지 않으나, 장시간 사용하게 되면 절삭유에 함유된 불순물은 자중에 의해 하부로 침전되고 나머지의 절삭유만 순환시켜 재사용을 하고 있으므로 상기 절삭유는 순환의 과정에서 유동으로 인해 불순물이 함유된 상태로 순환을 하게 되어 분사노즐을 막게 되는 요인으로 작용하였다.This coolant does not cause any problem when it is initially supplied, but when used for a long time, impurities contained in the coolant are settled downward by their own weight, and only the remaining coolant is circulated and reused, so the coolant flows in the circulation process. Due to the circulation in the state containing impurities, it acted as a factor to block the injection nozzle.

또한 상기와 같이 절삭유에 함유된 불순물이 절삭유와 함께 이동이 되므로 인해 장비에 과부하게 발생하게 되어 동력의 손실이 과도할 뿐만 아니라 가공도중 절삭유의 공급불량으로 인해 절삭물과 절삭공구에 과열이 발생하게 되어 가공의 효율성이 불량하게 되고, 한편으로는 절삭공구가 파손되거나 심하게 마모되는 등의 현상이 발생하여 상기 절삭공구의 교체에 따른 시간적인 손실은 물론, 장비의 정지로 인한 작업능률이 저하되는 요인으로 작용하였다.In addition, as described above, impurities contained in the cutting oil are moved together with the cutting oil, resulting in overloading of the equipment, resulting in excessive power loss and overheating of the cutting and cutting tools due to the supply of the cutting oil during processing. As a result, the efficiency of machining becomes poor, and on the other hand, a phenomenon such as a broken or severely worn cutting tool occurs, which causes a loss of time due to replacement of the cutting tool and a decrease in work efficiency due to the stop of the machine. Acted as.

따라서 근래에는 상기와 같은 문제점을 해소하고자 특허등록 제387169호, 특허등록 제805248호의 절삭유 여과장치가 제공되어 있으나, 이들은 모두 필터의 상부에서 필터내부로 불순물이 함유된 절삭유를 공급하고 그 공급된 절삭유는 필터의 내부에서 외부로 빠져나오면서 여과되어 하부의 드레인관을 통하여 다시 해당 공작기계에 공급되게 되는 것이다.Therefore, in order to solve the above problems, the cutting oil filtration apparatus of Patent Registration No. 387169 and Patent Registration No. 805248 has been provided, but all of them supply cutting oil containing impurities from the upper part of the filter to the inside of the filter and supply the cutting oil.

도3 및 도4는 본 발명의 절삭유 여과장치 제1 및 제2실시예의 단면 구성도로서, 그를 참조하여 상세하게 설명하면 다음과 같다.3 and 4 are cross-sectional configuration diagrams of the cutting oil filtration device first and second embodiments of the present invention, which will be described in detail with reference to the following.

필터바디(10)의 내측 상부에는 내주 면을 따라 플렌지(11)가 형성되어 그 플렌지(11)를 중심으로 상부는 상부오일수용부(12), 하부는 하부오일수용부(13)로 구분하며, 상기 필터바디(10)의 상단에는 절삭유가 누유되지 않도록 커버(14)가 견고히 결합되는데 그 결합은 분해결합 가능하게 결합되고, 상기 필터바디(10)의 하단에는 밸브(V1)를 갖는 드레인 관(15)이 설치되어 있다. A flange 11 is formed along the inner circumferential surface of the inner side of the filter body 10, and the upper portion is divided into an upper oil receiving portion 12 and a lower oil receiving portion 13 around the flange 11. The cover 14 is firmly coupled to the upper end of the filter body 10 so that cutting oil is not leaked. The coupling is coupled to be disassembled and coupled to the lower end of the filter body 10. (15) is provided.

상기 플렌지(11)를 형성시킨 이유는 하기에서 설명되는 백 필터(20)의 상단과 안전하고 견고하며 긴밀한 결합을 유도하기 위함이며, 상부오일수용부(12)는 백 필터(20)에 의해 여과된 절삭유가 수용되는 곳이고, 하부오일수용부(13)는 백 필터(20)에서 여과되기 전의 불순물이 함유된 절삭유가 진행하는 곳이다.The reason for forming the flange 11 is to induce a safe, firm and tight coupling with the upper end of the bag filter 20 described below, the upper oil receiving portion 12 is filtered by the bag filter 20 The cutting oil is accommodated, and the lower oil receiving portion 13 is a place where the cutting oil containing impurities before being filtered by the bag filter 20 proceeds.

상기 상부오일수용부(12)에 수용된 여과된 절삭유는 절삭유배출 관(50)을 통하여 배출되어 절삭유공급펌프(80)를 통하여 해당 공작기계(70)로 공급되는 것이고, 하부오일수용부(13)에 수용되는 절삭유는 절삭유수집탱크(T)에 수집된 불순물이 함유된 절삭유를 펌핑하는 펌프(P)를 통하여 절삭유공급 관(40)을 따라 공급되는 절삭유이다.The filtered cutting oil accommodated in the upper oil receiving part 12 is discharged through the cutting oil discharge pipe 50 and supplied to the corresponding machine tool 70 through the cutting oil supply pump 80, and the lower oil receiving part 13. The cutting oil accommodated in the cutting oil is a cutting oil supplied along the cutting oil supply pipe 40 through a pump P for pumping cutting oil containing impurities collected in the cutting oil collection tank T.

상기 커버(14)는 필터바디(10)의 상단에 결합되는 것으로 절삭유가 누유되지 않도록 견고하게 결합되고, 드레인 관(15)은 백 필터(20)에서 여과된 잔재물 즉 불순물과 일부의 절삭유가 혼합되어 함께 배출되는 곳이다.The cover 14 is coupled to the upper end of the filter body 10 and is firmly coupled so that cutting oil is not leaked, and the drain pipe 15 mixes residues, that is, impurities and some cutting oil, filtered from the bag filter 20. It is a place where it is discharged together.

또 상기 커버(14)에는 백 필터(20)내부로 에어를 공급하여 백 필터(20) 외부로 에어가 빠져나가도록 밸브(V4)를 갖는 에어공급 관(60)이 설치되는데, 그 에어공급 관(60)으로 에어를 공급하는 이유는 백 필터(20) 내부로 에어를 공급하여 그 에어가 백 필터(20)를 통과하여 외부로 빠져나가면서 백 필터(20)의 외부에 붙어 있는 불순물을 불어내어 세척하기 위함이다. In addition, the cover 14 is provided with an air supply pipe (60) having a valve (V4) to supply air into the bag filter 20 to escape the air to the outside of the bag filter 20, the air supply pipe The reason for supplying air to the 60 is to supply air into the bag filter 20 and blow out impurities attached to the outside of the bag filter 20 while the air passes through the bag filter 20 and escapes to the outside. To wash out.

단 상기 에어공급 관(60)으로 에어를 공급할 때에는 에어공급 관(60)의 밸브(V4)와 드레인 관(15)을 밸브(V1)는 열고, 절삭유공급 관(40)의 밸브(V2)와 절삭유배출 관(50)의 밸브(V3)는 닫는 것이 바람직하다. 그 이유는 에어공급 관(60)에서 공급되는 에어가 절삭유공급 관(40) 및 절삭유배출 관(50)으로 나가는 것을 방지하기 위함이다.However, when air is supplied to the air supply pipe 60, the valve V4 and the drain pipe 15 of the air supply pipe 60 are opened, and the valve V2 of the cutting oil supply pipe 40 and It is preferable that the valve V3 of the cutting oil discharge pipe 50 is closed. The reason for this is to prevent the air supplied from the air supply pipe 60 to go out to the cutting oil supply pipe 40 and the cutting oil discharge pipe 50.

한편 상기 도3의 필터바디(10) 하부는 상광하협의 깔때기 형상으로 형성되고, 그 깔때기 형상의 필터바디 하단 중앙에 드레인 관(15)이 연결 설치되는데, 상기 필터바디(10) 하부를 상광하협의 깔때기 형상으로 형성시킨 이유는 백 필터(20)에서 절삭유를 여과한 후 발생하는 잔재물 즉 불순물과 일부의 절삭유가 하단으로 모아져 드레인 관(15)으로 용이하게 배출되도록 하기 위함이다.On the other hand, the lower portion of the filter body 10 of FIG. 3 is formed in a funnel shape of the upper and lower sheaths, and the drain pipe 15 is connected to the lower center of the funnel-shaped filter body. The reason for forming the narrow funnel is that the residue generated after filtering the cutting oil in the bag filter 20, that is, impurities and some of the cutting oil are collected at the lower end and easily discharged to the drain pipe 15.

또 도4의 필터바디(10) 하부는 일 측 방향에서 타 측 방향으로 기울어지게 형성되고, 그 기울어진 필터바디의 끝단에 드레인 관(15)이 연결 설치되는데, 상기 필터바디(10) 하부를 일 측 방향에서 타 측 방향으로 기울어지게 형성시킨 이유는 상기 도3과 마찬가지로 백 필터(20)에서 절삭유를 여과한 후 발생하는 잔재물 즉 불순물과 일부의 절삭유가 하단으로 모아져 드레인 관(15)으로 용이하게 배출되도록 하기 위함이다. In addition, the lower portion of the filter body 10 of FIG. 4 is inclined from one side direction to the other direction, and the drain pipe 15 is connected to the end of the inclined filter body, and the lower portion of the filter body 10 is provided. The reason why it is formed to be inclined from one side direction to the other direction is the same as that of FIG. To be discharged.

또한 상기 백 필터(20)의 상단과 커버(14)의 사이에는 백 필터 고정수단(30)이 설치되는데, 그 백 필터 고정수단(30)이 설치하는 이유는 백 필터(20)의 형상을 유지함과 동시에 백 필터(20)의 유동을 제어하고 백 필터(20)의 상단과 플렌지(11)간에 견고한 고정력을 유지하도록 하기 위함이다.In addition, the bag filter fixing means 30 is installed between the top of the bag filter 20 and the cover 14, the reason that the bag filter fixing means 30 is installed to maintain the shape of the bag filter 20 And at the same time to control the flow of the bag filter 20 and to maintain a firm fixing force between the top of the bag filter 20 and the flange (11).

상기 백 필터 고정수단(30)의 제1실시예로는 커버(14)에 설치된 고정 축(31)을 매개로 고정 설치되어 백 필터(20)의 형상을 유지함과 동시에 백 필터(20)의 유동을 제어하는 필터고정브래킷(32)과, 그 필터고정브래킷(32)과 커버(14)의 사이에 위치하도록 상기 고정 축(31)에 끼워져 백 필터(20)를 상부에서 하부로 밀어내는 탄성스프링(33)으로 이루어진다.The first embodiment of the bag filter fixing means 30 is fixedly installed through the fixing shaft 31 installed on the cover 14 to maintain the shape of the bag filter 20 and at the same time the flow of the bag filter 20 An elastic spring for fitting the filter fixing bracket 32 and the filter fixing bracket 32 and the cover 14 so as to be positioned between the fixing shaft 31 and pushing the bag filter 20 from the top to the bottom thereof. It consists of 33.

상기 필터고정브래킷(32)은 백 필터(20)의 형상을 유지함과 동시에 백 필터(20)의 유동을 제어하는 지지역할을 하고, 탄성스프링(33)은 백 필터(20)의 상단을 하방으로 밀어내어 플렌지(11)와 백 필터 상단 간에 긴밀한 결합력을 유지함으로써 하부오일수용부(13)에 수용된 절삭유가 상부오일수용부(12)로 역류하지 못하도록 한다.The filter fixing bracket 32 maintains the shape of the bag filter 20 and at the same time serves to control the flow of the bag filter 20, and the elastic spring 33 moves the upper end of the bag filter 20 downward. By pushing out and maintaining a close coupling force between the flange 11 and the top of the bag filter to prevent the cutting oil contained in the lower oil receiving portion 13 to flow back to the upper oil receiving portion (12).

상기 백 필터(20)의 상단은 필터바디(10)에 형성된 플렌지(11)와 견고한 결합을 위하여 플렌지가 형성되어 있으며, 상기 양 플렌지의 사이에는 기밀성 확보를 위하여 실링부재를 개재시킴이 바람직하다.The upper end of the bag filter 20 is formed with a flange for firm coupling with the flange 11 formed on the filter body 10, it is preferable to interpose the sealing member to ensure the airtightness between the two flanges.

한편 상기 백 필터(20)가 설치된 후에는 필터바디(10)의 내주 면과 백 필터(20)의 외주면 사이에 소정의 간극이 발생하여 이로 절삭유공급 관(40)을 통하여 공급되는 불순물이 함유된 절삭유가 수용되는 것이다.On the other hand, after the bag filter 20 is installed, a predetermined gap is generated between the inner circumferential surface of the filter body 10 and the outer circumferential surface of the bag filter 20, thereby containing impurities supplied through the cutting oil supply pipe 40. Coolant is received.

그리고 상기 절삭유공급 관(40)은 도5에 나타낸 바와 같이 절삭유공급 관(40)의 토출구가 필터바디(10)의 내주 면과 백 필터(20)의 사이 간극을 향하도록 형성되고 상기와 같은 절삭유공급 관(40)은 20 - 50ㅀ로 기울기를 갖도록 경사지게 설치된다.The cutting oil supply pipe 40 is formed such that the discharge port of the cutting oil supply pipe 40 faces the gap between the inner circumferential surface of the filter body 10 and the bag filter 20 as shown in FIG. The supply pipe 40 is installed inclined so as to have a slope of 20-50 kPa.

그 이유는 펌프(P)의 펌핑 력에 의해 절삭유공급 관(40)으로 공급되는 절삭유는 1bar이상의 압력을 유지한 상태임으로 하부오일수용부(13) 즉 필터바디(10)의 내주 면과 백 필터(20)의 외주면 사이의 간극으로 공급되는 절삭유가 백 필터의 외주 면을 따라 상부에서 하부로 회전하면서 하향 진행하도록 하기 위함이다.The reason is that the cutting oil supplied to the cutting oil supply pipe 40 by the pumping force of the pump P is maintained at a pressure of 1 bar or more, so that the inner circumferential surface of the lower oil receiving portion 13, that is, the filter body 10 and the bag filter This is to allow the cutting oil supplied to the gap between the outer circumferential surfaces of (20) to travel downward while rotating from the top to the bottom along the outer circumferential surface of the bag filter.

상기와 같이 절삭유가 백 필터의 외주 면을 따라 상부에서 하부로 회전하면서 진행하게 되면 절삭유에 함유된 불순물이 백 필터(20)의 외주 면에 부착되지 않고 필터바디(10)의 하부 드레인 관(15)이 설치된 쪽으로 모여 불순물의 여과 및 배출이 용이하게 이루어진다.(원심분리 원리)As the cutting oil proceeds while rotating from the upper side to the lower side along the outer circumferential surface of the bag filter, impurities contained in the cutting oil do not adhere to the outer circumferential surface of the bag filter 20 and the lower drain pipe 15 of the filter body 10 is removed. ) Can be easily gathered to the side where the impurities are filtered and discharged (centrifugal principle).

그리고 상기 드레인 관(15)의 밸브(V1)는 항상 1/4이하로 열려있게 되는데, 그 이유는 일부의 절삭유와 불순물이 혼합된 상태로 드레인 관(15)을 따라 드레인 되는 것이 불순물 배출에 효과적이기 때문이다. 또 상기 드레인 관(15)으로 드레인 되는 절삭유의 일부는 회수하여 재사용한다. 한편상기 드레인 관(15)의 밸브(V1)를 항상 1/4이하로 열어준다는 의미는 절삭유 여과장치(A)로 절삭유를 여과할 때이다.And the valve (V1) of the drain pipe 15 is always open to 1/4 or less, because the drain along the drain pipe 15 in a state in which some cutting oil and impurities are mixed to effectively discharge impurities Because it is. In addition, a part of the cutting oil drained to the drain pipe 15 is recovered and reused. On the other hand, the meaning that the valve V1 of the drain pipe 15 is always opened to 1/4 or less is when the cutting oil is filtered by the cutting oil filtering device A.

상기 드레인 관(15)은 필터바디(10)의 하단에서 상부오일수용부(12)의 절삭유수위보다 낮은 위치로 상향 절곡되게 구성되는데, 그 이유는 드레인 관(15)이 상부오일수용부(12)의 절삭유수위보다 높게 되면 불순물과 함께 드레인 되는 절삭유의 진행이 자동으로 이루어지지 않기 때문에 상기 불순물과 함께 드레인 되는 절삭유의 진행이 자동으로 이루어지도록 하기 위함이다.The drain pipe 15 is configured to be bent upward from the lower end of the filter body 10 to a position lower than the cutting oil level of the upper oil receiving portion 12, because the drain tube 15 is the upper oil receiving portion 12 When the cutting oil level is higher than), the cutting oil drained with the impurities is not automatically made, so that the cutting oil drained with the impurities is automatically made.

또한 본 발명의 절삭유배출 관(50)은 상부오일수용부(12)를 형성하는 필터바디(10)의 일 측에 설치되어 백 필터(20)에 의해 여과된 절삭유를 상부로 역류시켜 배출시키는데,(싸이클론 원리) 그 이유는 필터바디(10)의 하부에는 불순물이 존재하기 때문에 그 불순물과 혼합되지 않고 여과된 절삭유만 배출하도록 하기 위함이다.In addition, the cutting oil discharge pipe 50 of the present invention is installed on one side of the filter body 10 forming the upper oil receiving portion 12 to discharge the cutting oil filtered by the bag filter 20 to the top to discharge, (The cyclone principle) The reason for this is that impurities are present in the lower part of the filter body 10 so that only the filtered cutting oil is discharged without being mixed with the impurities.

상기 절삭유를 하부에서 상부로 역류시키는 힘(싸이클론 원리)은 공작기계로 절삭유를 공급하는 절삭유공급펌프(80)에서 흡입력이 발생되기 때문에 그 흡입력이 상부오일수용부(12)를 통하여 백 필터(20)내부로 전달되어 절삭유의 역류가 이루어지는 것이다. The force that flows back the cutting oil from the lower part to the upper part (cyclone principle) is a suction force generated in the cutting oil supply pump 80 that supplies the cutting oil to the machine tool, and the suction force is applied to the bag filter through the upper oil receiving part 12. 20) It is transmitted inside to reverse the flow of cutting oil.

참고로 절삭유공급펌프(80)에는 회전되는 임펠러가 다단계로 설치되어 있기 때문에 그 임펠러의 후방에서는 흡입력이 발생된다. 이는 통상의 기술임으로 그에 대한 구체적인 설명은 생략한다.For reference, since the impeller rotating in the cutting oil supply pump 80 is installed in multiple stages, suction force is generated at the rear of the impeller. Since this is a conventional technology, a detailed description thereof will be omitted.

이상에서 설명된 바와 같은 본 발명의 절삭유 여과장치(A)는 절삭유수집탱크의 불순물이 함유된 절삭유를 펌프(P)가 펌핑하여 절삭유공급 관(40)을 통하여 필터바디(10)의 내주 면과 백 필터(20)의 사이 간극으로 공급되면 그 공급된 절삭유는 간극(하부오일수용부(13))내부에서 회전하면서 백 필터(20) 내부의 흡입력에 의해 백 필터(20)를 통과하여 여과된 절삭유는 절삭유배출 관(50)을 배출되고 상기 백 필터(20)를 통과하지 못한 일부 절삭유와 불순물은 드레인 관(15)으로 배출되는 것이다.Cutting oil filtration device (A) of the present invention as described above is the pump (P) pumping the cutting oil containing impurities of the cutting oil collection tank and the inner peripheral surface of the filter body (10) through the cutting oil supply pipe (40) When supplied into the gap between the bag filter 20, the supplied cutting oil is rotated in the gap (lower oil receiving part 13) and filtered through the bag filter 20 by suction force inside the bag filter 20. The cutting oil discharges the cutting oil discharge pipe 50 and some of the cutting oil and impurities that do not pass through the bag filter 20 are discharged into the drain pipe 15.

한편 본 발명의 절삭유 여과장치는 도6 및 도7에 나타낸 바와 같이 2가지 타입으로 형성되는데, 그중 도6의 절삭유 여과장치는 수동타입이고, 도7의 절삭유 여과장치는 자동타입으로써, 도6의 절삭유 여과장치와 도7의 절삭유 여과장치 차이점 은 절삭유배출 관(50) 및 에어공급 관(60)에 설치된 각 밸브(V3.V4)의 형태로써 도6의 절삭유 여과장치 각 밸브(V3.V4)는 수동밸브이고, 도7의 절삭유 여과장치 각 밸브(V3.V4)는 솔레노이드 밸브로써 상기 도6의 각 수동밸브(V3.V4)를 열고 닫을 때에는 사람이 직접 레버를 작동시켜 열고 닫는 반면에 상기 도7의 각 솔레노이드(V3.V4)는 전기 공급 및 차단에 의해 자동으로 열리고 닫히게 된다.Meanwhile, the cutting oil filtration apparatus of the present invention is formed in two types, as shown in FIGS. 6 and 7, wherein the cutting oil filtration apparatus of FIG. 6 is a manual type, and the cutting oil filtration apparatus of FIG. 7 is an automatic type. The difference between the coolant filter apparatus and the coolant filter apparatus of FIG. 7 is in the form of each valve (V3.V4) installed in the coolant discharge pipe 50 and the air supply pipe 60, and each coolant filter valve (V3.V4) of FIG. 7 is a manual valve, and each of the coolant filtration valves V3.V4 of FIG. 7 is a solenoid valve, and when the manual valves V3.V4 of FIG. 6 are opened and closed, a person directly operates the lever to open and close the valve. Each solenoid V3.V4 of FIG. 7 is automatically opened and closed by electricity supply and interruption.

한편 상기 도6 및 도7의 절삭유 여과장치에서 에어공급 관(60)의 밸브(V4)가 열리면 절삭유배출 관(50)의 밸브(V3)는 닫히고, 반대로 에어공급 관(60)의 밸브(V4)가 닫히면 절삭유배출 관(50)의 밸브(V3)는 열리는 작용이 필수적으로 이루어져야 한다.On the other hand, when the valve V4 of the air supply pipe 60 is opened in the cutting oil filtration device of FIGS. 6 and 7, the valve V3 of the cutting oil discharge pipe 50 is closed, and on the contrary, the valve V4 of the air supply pipe 60 is closed. When the valve is closed, the valve V3 of the cutting oil discharge pipe 50 must be essentially opened.

상술한 바와 같은 본 발명은 절삭유를 여과하면서 필터내부에 불순물이 누적되는 것을 방지하고, 또 절삭유의 불순물 여과와 동시에 그 여과된 불순물을 자동으로 인출되게 하며 필터의 장기간사용으로 필터의 외부에 불순물이 부착되게 되면 그 부착된 불순물을 에어를 이용하여 자동으로 세척함으로써 종래 문제시 되던 공작기계의 작동 정지 및 훼손 되는 문제점을 해소하고, 필터의 사용수명을 연장하며, 절삭유의 여과 효율을 높일 수 있는 장점이 있다.As described above, the present invention prevents impurities from accumulating inside the filter while filtering the cutting oil, and automatically removes the filtered impurities simultaneously with the filtering of the cutting impurities. Once attached, the attached impurities are automatically cleaned using air to eliminate the problem of machine stoppage and damage, which extends the service life of the filter and increases the filtration efficiency of cutting oil. There is this.
