摘要： PROBLEM TO BE SOLVED: To eliminate the influence due to turbidity of water to the monitoring work, and to reduce the quantity of the waste by sucking the abrasive used for cutting and the chips together for recovery with a recovering device, and separating the recovered chips and the abrasive from each other with a separat ing means. SOLUTION: An underwater cutting device 1 is provided with a recovery device 8 for recovering the abrasive and chips. This recovery device 8 is provided with various kinds of facing catchers 11 corresponding to the shape of a material to be cut and a lower cashier 13 installed in a frame 12 to be loaded with the material to be cut. The recovered abrasive and the chips separated from each other by a separating device 14 while using the magnetism. Furthermore, the abrasives separated by the separating device 14 are fractionated by a classifying device 15 according to their grain diameters. With this structure, since cutting can be performed while sucking the chips and the abrasive for recovery, influence of the turbidity of water to the monitoring work is eliminated. Furthermore, since the abrasive and the chips are separated from each other, quantity of the waste can be reduced.
