A composite machine tool which can continuously execute laser machining to diversified slopes of a work having a 3-D shape without changing the attitude of the work in a composite machine tool capable of alternately executing cutting and laser machining on a single machine. A laser machining arbor (44) of this composite machine tool (10) includes a fitting portion (54) which is in close contact with a tool support portion (40) of a spindle (28), a communication portion (62) rotatably supported by the fitting portion (54), and an outgoing portion (68) so connected to the communication portion (62) through a shaft (66) as to be capable of rocking. The fitting portion (54) and the communication portion (62) are equipped with a first passage (64) penetrating therethrough in an axial direction, and the outgoing portion (68) is equipped with a second passage (70) penetrating therethrough in the axial direction. A lens (72) for converging a laser beam is fixedly disposed in the second passage (70) of the outgoing portion (68). A movable reflection plate (78) supported by a shaft (66) is provided between the first and second passages (64, 70). The movable reflection plate (78) rotates around the shaft (66) interlocked with the relative rocking motion of the outgoing portion (68) relative to the fitting portion (54) and to the communication portion (62), and guides a laser beam passing through the first passage (64) to a lens (72) inside the second passage (70) at all the rocking inclined positions of the outgoing portion (68). <IMAGE> |
