Abstract

PURPOSE:To automatically determine the height of the liquid level in a machining tank in accordance with the change of the outer diameter of a roll, and to prevent an electrode holder from being immersed in a machining liquid, by providing a partition for allowing the liquid to overflow, and an apparatus for vertically driving the partition. CONSTITUTION:The electrode holder 7 is positioned previously at the machining position according to the dimension of the roll 1, and the partition 13 for allowing the machining liquid to overflow is positioned at the lowest position. Then the machining liquid is introduced into the machining tank 3, until the liquid level reaches the top of the partition 13, when the partition driving apparatus 14 is driven to raise the partition 13 at a speed slower than the rising speed of the liquid level. Thereafer when a liquid level positioning float switch 15 of the electrode holder 7 is actuated by the machining liquid, the input to the apparatus 14 is cut off to stop the partition 13 so that the height of the liquid level in the machining tank is automatically set.
