PURPOSE: An automatic working fluid supplying apparatus is provided to prevent damage to a machine tool when the working fluid of the machine tool is lower than a fixed level and the machine tool is continuously operated. CONSTITUTION: An automatic working fluid supplying apparatus comprises a main body, a working fluid discharge pipe(43), a sensor(45), a feeding pipe(37), a pump(44), a pumping motor(32), an operating button(33), an operating lamp(34), an alarm buzzer(35), an alarm lamp(36), and a low-level sensor(42). The main body is installed on a transportable working fluid drum(20). The working fluid discharge pipe is inserted into the working fluid telecommunications outlet of the working fluid drum can. The sensor is installed at the lower part of the working fluid discharge pipe and senses the level of the working fluid in the working fluid drum. The working fluid feeding pipe is connected to a working fluid supply hole of the working fluid supply vessel of the machine tool. The pump is installed in the main body and is positioned between the working fluid discharge pipe and the working fluid feeding pipe. The pumping motor is installed in the main body and provides the driving force to a pump. The alarm buzzer and the alarm lamp alarms operators to replace the working fluid drum if the working fluid is lower than the fixed level. The low-level sensor senses the level of the working fluid of the working fluid supply vessel.
