Radial and axial run-out
A correctly mounted spindle bearing on
the cut-off machine is essential for a
long service life and efficient operation
of the diamond cutting wheel.
Using a cutting wheel on a cut-off
machine with defective spindle bearing
can lead to axial and radial run-out.
Working safely with cut-off machines
All manuals and user guides at all-guides.com
Excessive radial run-out (A) causes
individual diamond segments to be
overloaded and to overheat. This can in
turn lead to stress cracking in the wheel
core or to softening of individual
segments.
Axial run-out or wobble (B) results in
higher thermal stress and wider cuts.
