The wire saw used by the wire saw machine in stone mining and cutting is divided into wire ropes for cutting granite hard stone, and wire ropes for cutting soft stones such as marble, limestone and travertine. When mining granite and sandstone, the wire saw with injection molding structure must be used, which not only makes the use of safety issues, but also the wear resistance issue more important. The wire saw with injection-molded structure is made of polyurethane plastic with good wear resistance as the fixed spacer between the beads. The gap between the beads and the wire rope is completely filled with plastic. Feldspar particles enter between the beads and the wire rope, and the wire rope is damaged by abrasion. The manufacturing process of the hot-pressed sintered wire rope and the selected binder metal are similar to those of the hot-pressed sintered diamond cutter head. The sintered beads have good wear resistance. Because granite has a wide range of hardness, by adjusting the ratio of different components of metals in the bond, diamonds with different strengths and particle sizes can be selected, and the wear rate of the bond matrix and the best exposure time of diamond crystals can be changed. For cutting beads of granite of different hardness and wear properties. However, the spring type wire rope using electroplating beads, the bead diamond coating is thin, the wear resistance of the base metal is poor, and it cannot withstand the abrasion of the high-hardness quartz component in the granite. If you cut granite with electroplated bead spring wire rope, the beading life is extremely low. More importantly, the quartz particles can easily enter the gap between the beads, the washer, the spring and the steel wire, and the thin steel wire core rope will be ground and broken, which will reduce the strength of the whole steel wire rope.
