In a coolant system, the interior of a reservoir frame (51) storing the coolant discharged from a machine tool (10) is partitioned by a partition member (52) into an outer peripheral coolant tub (53) and a central coolant tub (54). The partition member (52) is formed with a silt (52a) that extends in the depth direction to make the outer peripheral coolant tub (53) communicate with the central coolant tub (54). A suction port (61) of a pump (60) that feeds the coolant in the central coolant tub (54) to a filtering device (70) is arranged in the central coolant tub (54). The coolant discharged from the machine tool (10) is supplied to the central coolant tub (54) without passing through the outer peripheral coolant tub (53). At least a part of the coolant filtered by the filtering device (70) is supplied to the outer peripheral coolant tub (53) without passing through the central coolant tub (54). |
