본 발명은 절삭 가공용 칩 필터링 시스템에 관한 것으로서, 보다 상세하게는 절삭가공 후 발생하는 칩의 처리를 위해 진동필터링 방법을 적용하여 여과정도 및 제거율을 향상시키는 절삭 가공용 칩 필터링 시스템에 관한 것이다.The present invention relates to a chip filtering system for cutting, and more particularly, to a chip filtering system for cutting to improve the degree of filtration and removal rate by applying a vibration filtering method for the treatment of chips generated after cutting.

자동차 엔진 내에서 피스톤의 왕복운동을 회전운동으로 변환시켜주는 크랭크 축 등을 절삭가공하게 되면 칩이 발생하게 되고, 이러한 칩은 절삭유와 함께 배출되는데, 절삭유를 재사용하기 위해서는 칩을 분리시키고 개끗하게 분리된 절삭유를 배관라인을 통해 절삭 가공기에 공급하게 된다.When machining the crankshaft, which converts the reciprocating motion of the piston into a rotary motion, the chip is generated, and the chip is discharged along with the cutting oil.The chip is separated and cleaned to reuse the cutting oil. The coolant is supplied to the cutting machine through the pipe line.

이와 같이 칩을 분리시키는 종래 절삭 가공용 칩 필터링 시스템은, 도1에 도시한 바와 같이, 절삭유(coolant)와 칩(chip)이 혼합된 혼합물이 저장되는 혼합 탱크(2)의 내부에는 저류화는 칩을 운반하여 1차로 제거하는 콘베이어(4)가 설치되고, 상기 혼합탱크(2)의 상측에는 1차로 칩이 제거된 절삭유에 포함된 미세한 칩을 2차로 제거하는 필터기(8)가 설치되며, 상기 혼합탱크(2)의 일측에는 상기 필터기(8)를 통과하여 깨끗하게 된 절삭유를 모으는 정제 탱크(10)가 설치된 구조로 되어 있다.As shown in FIG. 1, in the conventional chip filtering system for separating chips as described above, chips stored in the mixing tank 2 in which a mixture of coolant and chips are stored are stored. Conveyor (4) is installed to transport the first to remove the first, the upper side of the mixing tank (2) is provided with a filter (8) for secondly removing the fine chips contained in the cutting oil from which the chip is first removed, One side of the mixing tank (2) has a structure in which a purification tank (10) for collecting cutting oil that has passed through the filter (8) is collected.

상기 종래 절삭 가공용 칩 필터링 시스템에서, 트렌치(trench : 12)를 통해 상기 혼합 탱크(2)에 유입되는 혼합물 중에 포함된 칩(chip)은 콘베이어(4)상에 쌓이게 되는데, 상기 콘베이어(4)가 가동되면서 칩을 1차로 외부로 배출시켜 스크래퍼를 사용하여 제거한다. 이와 같이 1차로 칩이 제거된 혼합물은 망(6)으로 구획된 공간(혼합탱크 내부공간)에서 필터 펌프(14)를 통해 상기 필터기(8)에 유입되어 미세한 칩이 2차로 제거되어 깨끗하게 되고, 깨끗한 절삭유는 상기 정제 탱크(10)에 유입되어 절삭유 공급 펌프(16)를 통해 절삭 가공기(M/C)에 재공급된다. In the conventional chip filtering system for cutting, chips contained in the mixture flowing into the mixing tank 2 through the trench 12 are stacked on the conveyor 4, where the conveyor 4 During operation, the chip is first discharged to the outside and removed using a scraper. In this way, the mixture from which the chips are first removed is introduced into the filter unit 8 through the filter pump 14 in the space partitioned into the network 6 (mixing tank internal space), and the fine chips are removed secondarily and cleaned. The clean cutting oil flows into the refining tank 10 and is re-supplied to the cutting machine M / C through the cutting oil supply pump 16.

그런데, 이와 같이 구성된 종래 절삭 가공용 칩 필터링 시스템은, 여과정도 및 제거율이 낮으므로 칩에 의한 배관 막힘이 발생하고, 정제 탱크를 혼합 탱크의 일측에 설치하므로 탱크 설치공간이 증가하며, 필터기에 절삭유를 공급하기 위한 별도의 펌프가 필요할 뿐만 아니라 필터기의 작동을 위한 액튜에이터를 설치해야 한다는 문제점이 있었다.However, in the conventional cutting chip filtering system configured as described above, since the degree of filtration and the removal rate are low, pipe blockage occurs due to the chip, and the purification tank is installed on one side of the mixing tank, thereby increasing the tank installation space. In addition to the need for a separate pump to supply, there was a problem in that an actuator for operating the filter must be installed.

따라서, 본 발명은 상기 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 칩 처리의 여과정도 및 제거율을 향상시키고 설치공간을 감소시켜 공간활용의 효율성을 증대하는 절삭 가공용 칩 필터링 시스템을 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, an object of the present invention to improve the filtration degree and removal rate of the chip treatment and to reduce the installation space to provide a chip filtering system for cutting processing to increase the efficiency of space utilization have.

In the chip filtering system for processing, a vacuum chamber in which cutting oil sucked out by a suction pump suctioning cutting oil in the mixing tank is installed at a lower portion of the mixing tank, and is circulated by a driving motor between the mixing tank and the vacuum chamber. Characterized in that the belt-shaped filter is provided.
