Exotom-100
Instruction Manual

There are two ways to set the stop position: AutoStop or Fixed
Stop.
When the AutoStop function is selected, the machine
automatically stops when the workpiece has been cut through.
For normal cutting, the AutoStop function is recommended.
In the Cutting Menu, toggle between FORCE/FEED/STOP by
pushing the knob, until STOP is highlighted.
Turn knob to move pointer to setting AUTO at the bottom of the
STOP column.
When the pointer in the STOP column is not on AUTO, Exotom-
100 will only stop when it reaches the preset stop position or the
STOP
o
key is pressed.
Note: AutoStop acts on sudden load changes. In some cases, eg
using very low feed rate and/or low force, subtle load changes may
not be detected by the machine, preventing AutoStop from
working properly. This may particularly be the case when cutting
soft materials, pipes or workpieces with changing cross-section.
If you are facing problems repeatedly, the sensitivity of the
AutoStop-function may be adjusted to fit your specific application.
Please contact your Struers service engineer for details.
Fixed stop is used when a specific stop position is desired. When
cutting pipes or other workpieces with changing cross sections,
the cut-off wheel may retract before the workpiece has been cut.
To overcome this, use the Fixed Stop function.
Clamp the workpiece and position the cut-off wheel just above the
workpiece.
This position is automatically set to 0 (zero) and indicated by the
cut-off wheel icon
to the right of the Stop column.
Accordingly, as soon as Start has been pressed, the actual position
of the cut-off wheel, becomes a relative starting point (zero), from
where the cutting depth is calculated.
Select the STOP parameter and set the desired stop position by
turning the knob.
Exotom-100 will now stop when it reaches the pre-set stop
position.
Remember to take the wear of the cut-off wheel into
consideration.
