Abstract
A fluid level adjusting apparatus in an electric discharge machining tank includes an exhaust pipe connected to a machining fluid exhaust port of the machining tank, an adjustment pipe having an upper opening end and a lower opening end connected to the exhaust pipe and height adjusting apparatus automatically adjusting the height of the upper opening end of the adjustment pipe so that machining fluid in the electric discharge machining tank is drained out of the machining tank through the upper opening end of the adjustment pipe to maintain the fluid level of the machining fluid at the height of the upper opening end. The height adjusting apparatus includes a driving section for generating a rotating force, a transmission section connected to the driving section for transmitting the rotary driving force, a converting section connected to the transmission section for converting the transmitted rotary driving force into a linear force for adjusting the height of the adjustment pipe upper end and a controlling section for delivering fluid level adjusting command data to the driving section.
