Beschreibung
Zusammenfassung:	The invention provides an accordion cover and a cutting apparatus using the same, capable of preventing a cutting liquid in a mist state from moving from a lower surface of the accordion cover to an upper surface. The accordion cover (41) is telescopic and the two side parts are supported by supporting rails (44, 45). An upper surface (41a) and a lower surface (41b) of the accordion cover (41) are formed in concaves and convexes. The concaves and convexes (44) of the accordion cover can deter the moving of a cutting liquid (Wa), and form gaps (46) in the lower surface of of a contracted accordion cover, and therefore saves the cutting liquid (Wa). The accordion cover can prevent the cutting liquid in a mist state from moving from the lower surface of the accordion cover to the upper surface of the accordion cover.
