Undercut
Do not cut into the base course
(frequently chipped stones and gravel)
when cutting roadway pavement –
cutting in chipped stones and gravel is
revealed by light-colored dust –
excessive undercut may occur as a
result – Danger of shattering!
Built-up edges, sharpen
Built-up edges take the form of a light
gray deposit on the tops of the diamond
segments. This deposit on the segments
clogs the diamonds and blunts the
segments.
Built-up edges can form:
–
when cutting extremely hard
materials, e. g., granite
–
with incorrect handling, e. g.,
excessive feed effort
Built-up edges increase vibration,
reduce cutting performance, and cause
formation of sparks.
At the first signs of built-up edges,
immediately "sharpen" the diamond
abrasive wheel – to do this, briefly cut
through abrasive material such as e. g.
sandstone, aerated concrete or asphalt.
Addition of water prevents the formation
of built-up edges.
If work continues with dull segments,
these may soften due to the high heat
generated – the parent wheel is
annealed and its strength is
compromised – this can lead to stresses
that are clearly recognizable by
gyrations of the abrasive wheel. Do not
continue to use the abrasive wheel –
Risk of accident!
The "support with guard" is mounted on
the inboard side by the manufacturer.
The "support with guard" can also be
mounted on the outboard side
depending on requirements.
Assembly on the inboard side is
recommended for freehand cutting on
account of the better balance.
