Wire guidance
Guide pulleys are fitted on the wire tension side and on
the return side (slack side). The wire is guided to the
object being sawn by way of these guide pulleys which
can be adjusted in any direction. Wire guides in the form
of single- or twin-pair pulley stands, plunge pulleys etc.,
are mounted at the start and end of the cut. The wire is
thus guided and cuts a controlled arc. The wire guides,
pulleys and supporting steel tube prevent the wire jump-
ing off uncontrollably at the end of the cut and act as a
safety device or as a wire trap in the event of the wire
breaking.
Optimum wire guidance is one of the most important
and demanding tasks in wire sawing. The distribution of
the cut and the arrangement of the pulley stands con-
trol the length and curvature of the arc cut by the wire,
thus influencing both the service life of the wire as well
as the rate of cutting progress.
