PROBLEM TO BE SOLVED: To provide a high-pressure liquid injection type cutting device capable of reducing a maintenance load of an abrasive sorting means executed by an operator. SOLUTION: The high-pressure liquid injection type cutting device is provided with an abrasive mixed liquid storage tank 22, a high-pressure liquid supply means 15, which sends out an abrasive mixed liquid with high pressure by supplying a high-pressure liquid to the abrasive mixed liquid storage tank 22, a spraying nozzle 30 for spraying the high-pressure abrasive mixed liquid to a workpiece 5, a catch tank 50 for receiving the sprayed high-pressure abrasive mixed liquid, an abrasive recovery means 60 for transferring a reusable abrasive having particle sizes in a prescribed range to the abrasive mixed liquid storage tank 22 after collecting it from the abrasive mixed liquid transferred from the catch tank 50, and a centrifugal type abrasive sorting means 70 which sorts out the abrasive with centrifugal force by making the abrasive mixed liquid transferred from the abrasive recovery means to rotationally flow, leads a dischargeable abrasive having a smaller particle size to a drainage path, and recovers an undischargeable abrasive having a larger particle size.
