A machine tool, comprising: a table; and a chip processing device including: a flushing duct installed on both sides of the table in a longitudinal direction of the table, in which one end portion of the flushing duct is inclinedly disposed and a lower cross-section thereof forms a V-shaped inclined surface, and a corner portion where both inclined surfaces meet forms a streamlined bending portion; a slope duct inclinedly disposed to allow a coolant supplied from the flushing duct to flow in a downward direction of one end portion of the table of the machine tool, in which a lower cross-section of the slope duct forms a V-shaped inclined surface, and a corner portion where both inclined surfaces meet forms a streamlined bending portion; a coolant supply valve installed at an upper end of the inclined flushing duct to supply the coolant to the flushing duct; a coolant tank provided below one end portion of the slope duct to collect the coolant fallen from both the flushing duct and the slope duct; and a centrifugal separator device installed at one side of the coolant tank to separate the microchips included in the coolant; wherein a primary filter is disposed at an inlet of the coolant tank for filtering large-sized chips among the microchips contained in the coolant supplied from the flushing duct and the slope duct, and a sliding plate is inclinedly installed below the primary filter toward a center portion of the coolant tank, and a primary return pump is provided at the center portion of the coolant tank whose suction port is disposed toward a bottom surface of the coolant tank to introduce and pump the coolant containing the microchips to a dirty tank of the centrifugal separator device, wherein a secondary filter is provided between the coolant tank and the dirty tank to filter the coolant which has not been transported through the primary return pump, to the dirty tank, wherein the coolant tank comprises a level sensor for detecting a level of the coolant in the coolant tank, and the primary return pump is configured to transport the coolant containing the microchips to the dirty tank of the centrifugal separator device when the coolant level detected by the level sensor is within a predetermined range, and wherein, when the coolant level detected by the level sensor reaches a predetermined maximum level, the level sensor is configured to make an emergency stop of the machine tool. a table;
