When mining and sawing, the linear speed of the wire rope decreases with the increase of the hardness of the cut stone and the cutting area. When the hardness of the stone is high and the cutting area is relatively large, the linear speed of the wire rope should also be reduced. If it is cutting soft stone, the cutting area is relatively small, and the cutting speed can be improved. Under normal circumstances, the linear speed of mining and cutting marble wire rope is 38-40 meters per second. When mining and cutting hard marble such as serpentine, the linear speed of the wire rope is 32-38 meters per second. When mining and cutting soft granite, the linear speed of the wire rope is 22-30 meters per second. When mining and cutting hard granite, the linear speed of the wire rope is 20-33 meters per second. The most suitable mining cutting line speed should be determined according to the type of stone mined, experiment and analysis to determine the best value. During trimming and plate cutting, the linear speed of the wire rope is determined according to the actual situation such as the type of stone and the length and size of the block. During normal cutting, the recommended linear speed of the wire saw is 24-26 meters per second for cutting granite and 30-32 meters per second for marble cutting. The harder the stone or the longer the face of the cut block, the lower the linear speed of the wire saw. Too high a line speed will cause the wire saw to become dull, too low will cause the bead to become oval or tapered.
