A machine tool and a cover device for the machine tool capable of preventing work cutting chips and coolant from falling on the rear part of a spindle head (8) and the operating positions of a first saddle (4) and a second saddle (6) without expanding the lateral width of the machine tool, wherein a column (2) is fixedly installed on a bed (1), the first saddle (4) is guided on the front surface of the column (2) movably in vertical direction (f1) , the second saddle (6) is guided on the front surface of the first saddle (4) movably in lateral direction (f2), and the spindle device (8) is guided on the second saddle (6) movably in longitudinal direction (f3) and, in addition, a first cover plate (31) is fixed to the second saddle (6), a side cover plate (33) is installed continuously with each of the right and left side edges of the cover plate (31) bendably in longitudinal direction (f3) , a second cover plate (39) is fixed integrally with the first saddle (4) , and a third cover plate (41) is installed fixedly to the front side of the second cover plate (39).
L'invention porte sur une machine-outil et son dispositif de couverture empêchant les copeaux et l'huile de coupe de tomber sur l'arrière de la tête (8) de broche et sur les positions de fonctionnement du premier coulisseau (4) et du deuxième coulisseau (6), et cela sans accroître la largeur de la machine. Une colonne est montée sur le banc (1), le premier coulisseau (4) coulisse verticalement le long de la surface frontale de la colonne (2), le deuxième coulisseau (6) coulisse latéralement (fo) le long de la surface du premier coulisseau (4) et la tête de broche coulisse longitudinalement (f3) sur le deuxième coulisseau (6). De plus, un premier bouclier (31) est fixé au deuxième coulisseau (6) et un bouclier latéral (33) flexible dans le sens longitudinal (f3) recouvre sans interruption les côtés gauche et droit du premier bouclier, un deuxième bouclier (39) est solidaire du premier coulisseau (4), et un troisième bouclier (41) est solidaire de la partie frontale du deuxième bouclier (39).
