1. A machine tool comprising:
a first cooling unit that cools at least one of a drive part that drives a component of the machine tool and an amplifier of the drive part;
a second cooling unit that cools the at least one of the drive part and the amplifier; and
a control unit that controls the first cooling unit and the second cooling unit,
wherein vibration caused by the second cooling unit is less than vibration caused by the first cooling unit, and
the control unit switches cooling of the at least one of the drive part and the amplifier, from cooling by the first cooling unit to cooling by the second cooling unit,
wherein the control unit is configured to control the drive part based on a machining program,
wherein the control unit switches from the cooling by the first cooling unit to the cooling by the second cooling unit, in response to a control command output from the control unit in accordance with the machining program to the drive part.
