Abstract
In a coolant system, the interior of a reservoir frame storing the coolant discharged from a machine tool is partitioned by a partition member into an outer peripheral coolant tub and a central coolant tub. The partition member is formed with a silt that extends in the depth direction to make the outer peripheral coolant tub communicate with the central coolant tub. A suction port of a pump that feeds the coolant in the central coolant tub to a filtering device is arranged in the central coolant tub. The coolant discharged from the machine tool is supplied to the central coolant tub without passing through the outer peripheral coolant tub. At least a part of the coolant filtered by the filtering device is supplied to the outer peripheral coolant tub without passing through the central coolant tub.
