1. A machine tool that performs machining of a work using a tool, the machine tool comprising
a base coolant pump;
a machining coolant pump that supplies coolant from the machining coolant pump to a machining area in which the machining is carried out;
a cleaning coolant pump that supplies the coolant from the cleaning coolant pump to a non-machining area; and
a controller that performs mode switching between
a half-wet machining mode in which, in addition to a base coolant being supplied by the base coolant pump, a coolant is supplied to the non-machining area to remove chips from the machine tool during the machining, and no coolant is supplied to the machining area, and
at least one of a wet machining mode in which the coolant is supplied to the machining area and a dry machining mode in which no coolant other than the base coolant is supplied into the machine tool, and
wherein said controller controls the pumps to turn off said machining coolant pump and turn on said base coolant pump and said cleaning coolant pump in the half-wet machining mode, turn on said base coolant pump, said machining coolant pump, and said cleaning coolant pump in the wet machining mode, and turn on said base coolant pump and turn off said machining coolant pump and said cleaning coolant pump in the dry machining mode.
