2. Description
Drive principle
The sawing wire is passed around the object to be cut,
over guide pulleys and the drive pulley before the ends
of the wire are joined to form an endless loop. The wire
loop is set in motion by rotation of the drive pulley and
pulled through the object to be cut by the linear advance
movement of the drive unit.
Saw advance and wire storage
Wire advance is by way of the “block and tackle” princi-
ple. The advance movement, i.e. causing the wire to be
drawn in, is effected by the pulleys being pushed apart
by a pneumatic cylinder. In addition, the drive pulley is
mounted on a moving carriage. The length of wire that
can be stored on the pulleys depends whether a single
or double return system is used, i.e. with or without the
optional wire storage pulley. Please refer to the “Tech-
nical data” section for further details.
Wire guidance
Alignment of the sawing wire between the pivoting pul-
ley on the machine and the pivoting pulley mounted on
the object being cut can be set precisely by adjusting the
pulleys. In flush cutting applications, the pivoting pul-
leys adjust automatically to the decreasing distance
between the wire entry and exit points by pivoting freely
as the cut progresses.
