Zusammenfassung:In this study, the design of UV-free reflecting reactor was studied to enhance the cutting fluid life for cutting machine. And also, the stability of cutting fluid with addition of biocide in cutting fluid and without biocide was compared with respect to the cutting fluid concentration, pH changes and microorganisms. Low number of microorganism was observed in the cutting fluid after UV-free reflecting treatment as compare to the cutting fluid which was added biocide and just cutting fluid alone. PH of the cutting fluid after UV-free reflecting treatment was about 9$\sim$8.5 while others were observed considerably low. The oil contents of cutting fluid which was added biocied and pure cutting fluid were almost degraded with the passage of time. However, in case of UV-free reflecting reactor, 4$\sim$3.5 Brix oil contents were observed in the cutting fluid. 본 연구에서는 UV-자유반사 반응조가 장착된 절삭장치와 단독 절삭장치 및 Biocide투입 절삭장치의 각각의 절삭유에 대해서 23주 동안 미생물 개체수와 pH변화, 유분농도 등을 분석하여 절삭유의 장기사용을 위한 각 절삭장치의 효율성에 대한 비교 검토를 하였다. 미생물의 개체수를 조사한 결과 UV 반응조 절삭유가 나머지 2기의 절삭유와 비교해 현저히 낮은 개체수를 보였으며 pH 또한 UV 반응조에서는 9$\sim$8.5를 유지하였으나 단독 절삭장치와 Biocide투입 절삭장치에서는 pH가 현저히 감소하는 경향을 나타내었다. 유분�t량의 경우 역시 절삭기 단독장치와 Biocide투입 절삭장치의 절삭유는 시간의 경과에 따라 유분함량이 거의 없는 상태로 나타나 절삭유로서의 기능을 상실한 것으로 판단되었다. 하지만 UV 반응조의 절삭유의 경우는 4$\sim$3.5 Brix를 유지한 것으로 나타났다.
