5
mm cable is made of 7 x 19 steel wires that can withstand a tensile
load of 1000Kg. |

3mm
cable is made of 7 x 7 steel wires that can withstand a tensile load
of 600 Kg. |

Hard
granites are for class 3 and higher; soft granites, for class 1 &
2. |

Twist
the wire 1.5 turns per meter before joining plastic sealed wires. For
profile cutting, the twist can be reduced to about 1 turn per meter. |
| 5. |
If
possible, use a wire speed higher than 30 m/s. In all cases, allow
ample amount of cooling water, in particular at where the wire enters
the rock, to prevent overheating of the cutting area that may destroy
the diamond or soften the plastic. |
| 6. |
Sawing
performance is dependent on rock type and cutting parameters. In
general, cutting speed per hour is expected to be higher than 1 m2 for
granite; and higher than 3 m2 for marble. The typical area of cut for
each meter of the wire saw is higher than 5 m2 for cutting granite;
and 20 m2 for cutting marble. |
