Abstract

PURPOSE: To eliminate the use of cooling water at a wire saw by providing cold air or refrigerant input tubes at a pair of guide tubes arranged between both pulleys and the sealing unit of a wire saw passing part. CONSTITUTION: A pair of guide tubes 10a, 10b formed of metal tubes are arranged between both pulley pairs 3 and 5. In the case of cutting, an endless wire saw S is passed through a guide pulley 5a via drive pulleys 3a, 3b in a moving track 2, and continued above and below a material W to be cut via the pulley 5a to be wound. Then, the tube 10b is passed through a guide pulley 5b, returned to the drive pulley via guide tubes 3c, 3d to drive the drive pulleys, the saw S is moved to cut the material W to be cut. The saw S is cooled by cold air or refrigerant in the case of passing the tubes 10a, 10b at an approach passage and a return passage to prevent the temperature rise of the saw S at the time of cutting.
