Since the distance to the tool is extremely short, even if the drive device has a cantilever support structure, the drive device has sufficient rigidity against the reaction force received during processing. In other words, since it is not necessary to provide an excessively strong structure in order to obtain rigidity, the machine width can be reduced in this respect as well. Furthermore, the machine tool 5 is extremely effective for operations such as maintenance and replacement because the machining module 10 is mounted on the movable bed 16 and moves back and forth on the base 2.
  • the headstock 12 and the column 31 are integrally configured, but may be configured to be separately fixed to the movable base 16 as long as the close positional relationship is maintained.
  • the machine tool is not limited to the turret lathe shown in the embodiment.
