Discotom-6
Instruction Manual
The following table shows answers to a number of common
questions about how to achieve better quality cuts:
Question
How can I avoid discoloration
or burning of the sample?
How can I avoid burrs?
How can I prevent the cut-off
wheel wearing out too quickly?
How can I cut more quickly?
*) Please refer to the Selection Guide in the
Struers Cut-off Wheels brochure.
The protection guard has a safety switch to prevent the cut-off wheel
from starting while the guard is open. Furthermore, a locking
mechanism prevents the operator from opening the protection guard
until the cut-off wheel stops spinning.
Answer
Reduce the feed speed
Change the cut-off wheel, as the
hardness of the present cut-off wheel
may be inappropriate for the hardness of
the workpiece*
Use a softer cut-off wheel*
Clamp the workpiece securely with the
quick-clamping devices.
Reduce the feed speed or use a harder
cut-off wheel*
Place the workpiece in a position which
allows the cut-off wheel to cut the
smallest possible cross-section. Increase
the feed speed.
