PROBLEM TO BE SOLVED: To provide a cutting liquid tank for machine tool preventing minute foreign substance remaining in filtered cutting liquid from precipitating on a bottom surface of flow in a flow passage and a tank to form sludge. SOLUTION: In a flow passage of cutting liquid after being filtered by a filter 7 of a separation vessel for separating foreign substance such as metal powder, a device having a vibration apparatus 11 directly attached on a reverse surface of a bottom surface or attached on a vibration plate thinner than the bottom surface of the flow passage is attached at a place where floating substance in the cutting liquid tends to precipitate to the bottom surface of flow due to decrease of flow speed or flow passage layout, and vibrates the place to forcedly float the precipitate and recirculate it together with cutting liquid to a pump 9.
