  • Patent number: 11951580
    Abstract: A coolant processing apparatus removes sludge from a coolant discharged from a machine tool. The coolant processing apparatus includes a first reservoir and a second reservoir provided in a tank for retaining the coolant. The first reservoir includes a flow path in which the discharged coolant flows, and a portion downstream of the flow path to retain the coolant such that the sludge remains in the first reservoir. The flow path has at least one bend to bend a flow of the coolant at least once in a horizontal direction. The second reservoir retains the coolant flowing out from the first reservoir. A boundary wall is provided between the first and second reservoirs, at a location downstream of the at least one bend of the flow path, and has such a height that allows a supernatant of the coolant in the first reservoir to flow into the second reservoir.
