The invention relates to a machine tool which processes a workpiece through the relative motions between a tool and the workpiece in X-, Y- and Z-axes three directions. The object of the invention is to ensure the collection and ejection of the chips with a simple configuration. The invention comprises a trough 27 provided in the central part of a bed 1 to extend in back-and-forth direction, a pair of guides 9 disposed at left-and-right sides of the trough 27 , a Z-axis feed screw 31 disposed adjacent one of the guides 9 , and slant covers 37 and Z-axis telescopic covers 39 for covering the pair of guides 9 and the Z-axis feed screw 31 . Chip conveyer nozzles 47 and 49 are provided within the trough 27 for directing the machining fluid to eject the chips from the machine.
