Disclosed is a cutting fluid sterilization apparatus with effect of scraping oil stain automatically which includes a cutting oil transportation component, a sterilization fluorescent tube and a sterilization fluorescent tube removing component. The sterilization fluorescent tube is disposed in the space of the cutting oil transportation component to sterilize the cutting oil. The sterilization fluorescent tube removing component includes an immobile end, a mobile end and a removing unit, wherein the immobile end is fixed at an end of the sterilization fluorescent tube while the mobile end is configured to be slidable relative to the immobile end in the longitudinal direction of the sterilization fluorescent tube, and the removing unit disposed at the immobile end and with a removing hole sleeves around the other end of the sterilization fluorescent tube slidably and rubs against the surface of the sterilization fluorescent tube, wherein the mobile end slides along the longitudinal direction of the sterilization fluorescent tube in such a manner that the removing unit removes the oil stain at the surface of the sterilization fluorescent tube through the rub between the removing hole and the sterilization fluorescent tube.一種具自動油汙刮除功能之切削油液殺菌裝置,包含一切削油輸送構件、一滅菌燈管及一滅菌燈管清除構件,滅菌燈管設置於切削油輸送構件的容置空間,以對切削油滅菌,滅菌燈管清除構件包括一固定端部、一活動端部及一清除件,固定端部固定於滅菌燈管之一端,活動端部經設置而相對於固定端部於滅菌燈管之長度方向上為可滑移,清除件設置於活動端部且具有一清除穿孔,並滑動地套置於滅菌燈管之另一端,而與滅菌燈管之表面互為摩擦接觸,其中藉由活動端部沿著滅菌燈管之長度方向滑移,使得清除件透過清除穿孔與滅菌燈管之間的摩擦而清除滅菌燈管之表面的汙垢。100‧‧‧刮除功能之切削油液殺菌裝置11‧‧‧抽取件12‧‧‧動力輸出件13‧‧‧輸入件14‧‧‧輸出件15‧‧‧滅菌燈管容置件16‧‧‧進油孔17‧‧‧出油孔18‧‧‧過濾件2‧‧‧滅菌燈管3‧‧‧滅菌燈管清除構件4‧‧‧定時構件41‧‧‧時間間隔設定件42‧‧‧清除運作時長設定件O‧‧‧油槽S‧‧‧容置空間
