FIELD: devices for sawing of hard materials, for example, natural or artificial stone. SUBSTANCE: the flanges of each machine cutting disk are provided with threaded hubs. The fixtures for re-adjustment of the distance between the cutting disks and their fixation against longitudinal displacements are made in the form of adjusting nuts having a threaded section and a ring stop, the threaded sections of the adjusting nuts are engageable with the threaded hubs, and the ring stops - with the split rings installed in the annular grooves of the drive shaft. The threads on the adjusting nuts and threaded hubs of the flanges on the opposite sides of the cutting disk have opposite directions. EFFECT: simplified construction of the fixture for re-adjustment of the distance between the cutting disks and their fixation against longitudinal displacements and simplified readjustment of the machine to another distance between the cutting disks. 2 cl, 1 dwg
