FIELD: abrasive treatment of glass workpieces. SUBSTANCE: machine tool contains feeding way and machining heads mounted at a distance from each other close to the feeding way. Glass workpiece moves along the feeding way. The heads are mounted for making contact with edge of the workpieces when the last moves along the feeding way. At least one of the heads removes the glass by means of abrasive treatment. Positioning system of the machining heads provides cyclic oscillating movement of the heads and the workpieces to produce waved bevel edge on the workpiece periphery. The machine tool contains, at least, one conveyor holding the workpiece and transporting it along the feeding way. The heads can be mounted to one carriage and work as one part or can be mounted independently from each other. The heads are moved along the workpiece periphery when machining. The heads or workpiece are imparted into oscillating movement. EFFECT: enhanced efficiency. 25 cl, 35 dwg, 1 tbl
