The invention discloses a cutting cooling device which is characterized in that the cutting cooling device comprises dry ice cooling devices arranged at the two sides of a cutting machine; the dry ice cooling device comprises a dry ice making machine, a dry ice high-pressure storage room connected with the dry ice making machine, a high-pressure nozzle connected with the dry ice high-pressure storage room, and a control switch connected with the high-pressure nozzle and an air blower component which is arranged beside the cutting machine and used for rapidly blow-drying crystal or water vapor. According to the cutting cooling device, dry ices are sprayed at two sides of a blade, so that the blade can be cooled rapidly; the dry ices can become carbon dioxide gas rapidly, so that the blade can not be corroded, and the efficient cooling is achieved.
