1. A chip processing device for a machine tool, comprising:
a respective flushing duct installed on each of two opposite sides of a table of the machine tool, each of the flushing ducts having a respective longitudinal axis that extends in a longitudinal direction of the table, wherein each of the flushing ducts has a respective one longitudinal end portion that is lower than the corresponding opposite longitudinal end portion thereof such that each of the flushing ducts is inclinedly disposed, and wherein each of the flushing ducts has a respective lower cross-section thereof that includes a respective pair of inclined surfaces that form a V-shape, and wherein for each of the flushing ducts, the corresponding pair of inclined surfaces are connected by a respective curved corner portion;
a slope duct inclinedly disposed at one longitudinal end portion of the table of the machine tool, the slope duct configured to allow a coolant that has been supplied to the slope duct from the flushing ducts to flow in a downward direction, wherein a lower cross-section of the slope duct includes a pair of inclined surfaces that form a V-shape, and wherein the inclined surfaces of the slope duct are connected by a curved corner portion;
a respective coolant supply valve installed at a respective upper end of each of the inclined flushing ducts to supply the coolant to the corresponding one of the flushing ducts;
a coolant tank provided below one end portion of the slope duct to collect the coolant fallen from both the flushing ducts and the slope duct; and
a centrifugal separator device installed at one side of the coolant tank to separate microchips included in the coolant;
wherein a primary filter is disposed at an inlet of the coolant tank for filtering larger-sized chips among the microchips contained in the coolant supplied from the flushing duct and the slope ducts;
wherein a sliding plate is inclinedly installed below the primary filter, which sliding plate is inclined in a manner so as to guide microchips contained in the coolant toward a center portion of the coolant tank;
wherein a primary return pump is provided at the center portion of the coolant tank, which primary return pump has a suction port that is disposed toward a bottom surface of the coolant tank in order to introduce and pump the coolant containing the microchips to a dirty tank of the centrifugal separator device; and
wherein a secondary filter is provided between the coolant tank and the dirty tank in order to filter the coolant, which has not yet been transported through the primary return pump, to be transported to the dirty tank.
