The pressurizing pump (5) sucks and pressurizes the clean working fluid (3a) from the storage tank (4), supplies it to the inlet (6a) of the jet pump (7), and discharges it at high speed toward the outlet (6c). . The jet pump (7) has a built-in nozzle, and the clean machining fluid (3a) pressurized from the nozzle is ejected into the suction pipe at a high speed, so that the periphery of the machining fluid (3a) becomes negative. It becomes pressure, and at the same time, a suction force is generated in the suction port (6b). This suction force becomes larger as the pressure of the clean working fluid (3a) required at the inlet (6a) of the jet pump (7) becomes higher. The cleaning liquid has a small amount of clean working fluid (3a) and can suck the working fluid (3b) (3c) containing a large amount of suspension from the suction port (6b).
