– the letters denote the main field of
application of the cutting wheel
– the numbers denote the
performance class of the STIHL
diamond cutting wheel
Axial and radial run-out
A faultless spindle bearing of the cut-off
machine is necessary for a long service
life and efficient functioning of the
diamond cutting wheel.
Using the cutting wheel on a cut-off
machine with a faulty spindle bearing
can lead to deviations in radial and axial
run-out.
An excessively high radial run-out
deviation (A) overloads individual
diamond segments, which overheat in
the process. This can lead to stress
cracks in the parent wheel or to
annealing of individual segments.
Deviations in axial run-out (B) result in
higher thermal loading and wider cuts.
