The line speed of wire saw decreases with the increase of stone hardness and cutting area. When the stone hardness is high and the cutting area is relatively large, the line speed of the wire saw should also be reduced. If it is cutting soft stone, the cutting area is relatively small, the cutting speed can be improved. In general, the line speed of mining and cutting marble wire saw is 38~40m/s; When mining and cutting serpentine hard marble, the line speed of wire saw is 32~38m/s; When the soft granite rock is mined and cut, the wire saw line speed is 22~30m/s. When mining and cutting hard granite rock, the line speed of wire saw is 20~33m/s. The most appropriate mining cutting line speed should be based on the type of stone mining, test and analysis to determine the best value.
