Abstract
An electric discharge machine capable of suppressing scattering and overflow of a liquid flowing out of a drain port. An electric discharge machine according to one embodiment includes a liquid tank for storing a liquid; a drain valve which opens/closes a drain port for draining the liquid stored in the liquid tank; an actuator which drives the drain valve; a liquid level sensor which detects the level of the liquid stored in the liquid tank; and a control unit which controls the actuator so that as the liquid level detected by the liquid level sensor is lower, the opening amount of the drain valve becomes greater.
Claims7
An electric discharge machine comprising a liquid tank configured to store liquid, a drain valve configured to open and close a drain port for draining the liquid stored in the liquid tank, and an actuator configured to drive the drain valve,
- the electric discharge machine further comprising:
- a liquid level sensor configured to detect a liquid level of the liquid stored in the liquid tank;
- and
- a control unit configured to control the actuator in a manner so that an amount of opening of the drain valve increases as the liquid level detected by the liquid level sensor decreases.
