In the upper part of a plurality of steel wire ropes, a certain amount of diamond bead particles are separated according to the proportion, and the adjacent beads are separated by a separating sleeve which is supported and fixed (like a necklace). The processing of diamond wire saw is the corresponding mechanical equipment by the direct participation of diamond wire cutting and driving motion (i.e. the wire rope saw machine) jointly completed before processing, using copper sleeve butt set Beaded rope end-to-end length, form a closed circle. When the utility model is processed, the closed loop bead rope tightly stretched on the guide rail group of the wire saw machine is used for high-speed movement of the bead rope under the driving force.
