<p>A machine tool, comprising
a base (100) adapted to be fixed on a floor and having a top face (1f) extending in a longitudinal direction (Y) and a lateral direction (X),
a machining head (102) having a vertical rotation driving shaft (26A) disposed in a vertical direction (Z),
a jig (28) for fixing a work adapted to be machined, and
a guide-driving means (101) formed on the top face (11) of the base (100), the guide-driving means (101) being adapted for displacing the machining head (102) in the longitudinal direction (Y), in the lateral direction (X) orthogonal to the longitudinal direction (Y), and in the vertical direction (Z) orthogonal to the longitudinal and lateral direction (Y,X) through guide parts (5,8,10),
wherein the guide-driving means (101) is provided with a first saddle (4) having a front face (4c) extending in the lateral direction (X) and the vertical direction (Z), a second saddle (7) being guided on the front face (4c) of the first saddle,
wherein the first saddle (4) is guided in the longitudinal direction (Y) on the top face (1f) of the base (100) and a second saddle (7) is guided in the lateral direction (X) on the front part of the first saddle (4), and
the guide-driving means (101) comprises a guide part (10) extending in the vertical direction (Z) on the second saddle (7) for guiding the machining head (102) in the vertical direction (Z),
characterized in that the base (100) is formed in an almost rectangular solid in which a front face (1c) is formed in a single plane orthogonal to a longitudinal direction (Y) and the jig (28) is installed at a vertical intermediate position of the front face (1c) so that the machining head (102) is displaced in three directions (X,Y,Z) in front of the single plane while the tool machines the work and cutting chips fall without accumulating on the base (100).
