Abstract
To perform cleaning in a machine while meeting a user's requirement to perform machining without supplying a coolant to a work or a tool, a machine tool that performs machining for a work using a tool includes a controller that performs mode switching between a half-wet machining mode in which a coolant is supplied to a non-machining area to remove chips in the machine tool during machining, and no coolant is supplied to a 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 is not supplied into the machine tool.
Claims7
A machine tool that performs machining for a work using a tool, comprising
- a base coolant pump;
- a machining coolant pump that supplies the coolant from the coolant pump to the machining area;
- a cleaning coolant pump that supplies the coolant from the coolant pump to the non-machining area;
- and
- a controller that performs mode switching between
- a half-wet machining mode in which, in addition to a base coolant, a coolant is supplied to a non-machining area to remove chips in the machine tool during machining, and no coolant is supplied to a 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 a coolant other than the base coolant is not supplied into the machine tool, and
- wherein said controller controls the pumps to turn off said cleaning coolant pump and turn on said base coolant pump and said machining 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.

A control apparatus of a machine tool that performs machining for a work using a tool,
- wherein the machine tool comprises:
- a base coolant pump;
- a machining coolant pump that supplies the coolant from the coolant pump to the machining area;
- and
- a cleaning coolant pump that supplies the coolant from the coolant pump to the non-machining area;
- wherein the control apparatus performs mode switching between
- a half-wet machining mode in which a coolant is supplied to a non-machining area to remove chips in the machine tool during machining, and no coolant is supplied to a 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 is supplied into the machine tool, and
- wherein the control apparatus controls the pumps to turn off said cleaning coolant pump and turn on said base coolant pump and said machining 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.
A control method of a machine tool that performs machining for a work using a tool, and comprises:
- a base coolant pump;
- a machining coolant pump that supplies the coolant from the coolant pump to the machining area;
- and
- a cleaning coolant pump that supplies the coolant from the coolant pump to the non-machining area,
- the control method comprising
- performing mode switching between
- a half-wet machining mode in which a coolant is supplied to a non-machining area to remove chips in the machine tool during machining, and no coolant is supplied to a 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 is supplied into the machine tool,
- wherein the pumps are controlled to turn off said cleaning coolant pump and turn on said base coolant pump and said machining 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.
