6.5 Planning wire guidance and sequence of cuts
• Thorough training and experience are the most important prerequisites for optimum
planning of the cutting configuration and wire guidance system.
• Long lengths of wire in contact with the object to be cut and cutting in a very flat arc
reduce sawing performance.
• When planning the cut, make sure that the wire contact length does not exceed
1.5 meters.
• Arrange the cutting sequence so that the diamond sawing wire cannot become
trapped by parts that are cut away.

Assembling the wire saw
7.1 Drilling through-holes
The location and positioning of the through holes has a direct influence on cutting
accuracy.
When walls are thick or permissible tolerances are minimal, you should use a rig-based
diamond coring machine to drill the through-holes.
When walls are thinner or permissible tolerances large, the through-holes can also be cut
with a rotary hammer drill.
Drilling diameter should be at least 16 mm. If the object to be cut is thick, drilling diameter
should be at least 4 % of the thickness of the object to be cut.
Rounding off right-angled edges of the object to be cut lets the sawing wire run smoothly
round the corners and prevents damage.
7.2 Installing base plate
WARNING
Risk of injury by flying parts.
Death and severe injuries can result.
▶
Operate the wire saw only with the wire saw and the wire guides correctly mounted
on the object to be cut.
