PROBLEM TO BE SOLVED: To perform workpiece processing having high degree-of-freedom, while suppressing thermal displacement of a cutter holder body at parts where rotary tools are attached.SOLUTION: A machine tool (1) includes: a cutter holder body 20 having a holder base part 30 of which a longitudinal direction (X direction) is in a direction different from an axial direction (Z direction) of a workpiece W1, and first and second holder leg parts 40, 50 which protrude in a direction different from the axial direction (Z direction) and the longitudinal direction (X direction) of the holder base part 30, from one end side (31) in the longitudinal direction and the other end side (32) in the longitudinal direction, of the holder base part 30, and to which rotary tools RT1, RT2 are attached; a motor 65 provided at the holder base part 30; a first force transmission mechanism 70 for transmitting rotational driving force of the motor 65 to the rotary tool RT1 attached to the first holder leg part 40; and a second force transmission mechanism 80 for transmitting the rotational driving force of the motor 65 to the rotary tool RT2 attached to the second holder leg part 50. |
