摘要： This machine tool (100) has: a main shaft (152) having a tool (T) mounted on the tip thereof; a main shaft head (120) that rotatably supports the main shaft; orthogonal triaxial linear feed shafts that move the main shaft and a table (122), on which a workpiece is mounted, relative to one another; and a rotational feed shaft that is capable of changing the orientation of the rotational axis (O) of the main shaft. The machine tool (100) is provided with: a rotational feed shaft device (118) that is not parallel to any of the linear feed shafts and that rotates the main shaft head around an inclined axis (O I ) that intersects the rotational axis of the main shaft; and a main shaft head base (112) that rotatably supports the main shaft head so that the point of intersection between the rotational axis and the inclined axis of the main shaft coincides with a defined reference point (P R ) at the tip side of the main shaft.

摘要： This machine tool (11) is provided with: a partition (71) that partitions a machining chamber (45) and a tool storage chamber (46) and that has an opening (79); a shutter (58); and a receiving member (85) that is formed so as to receive cutting fluid. The partition (71) includes a sidewall member (73a) that extends in the vertical direction and an inclined wall member (74) inclined in such a manner so as to become lower from the sidewall member (73a) to the interior of the machining chamber (45). At least part of the opening (79) is formed in the inclined wall member (74). The receiving member (85) is positioned beneath the shutter (58), and in such a position so as to receive cutting fluid that drops down along the sidewall member (73a) when the shutter is opened (58).
