Cluster
Dressers

Cluster type diamond
dressers consist of
a number of small
natural diamond of
good crystal
character, set in a
geometric pattern in
single layer and
sintered into a
special wear
resistant bond.
The cluster type
diamond dresser is
ideal for coarse or
rough dressing of
grinding wheels in
sizes up to 80 grit
(mainly rough
grinding or grinding
to eliminate
imbalance). The
diamonds can be
fully utilised
without re-setting
or re-sharpening.
Dressing costs are
substantially
reduced as the
diamonds used in
this type of
dressers are much
smaller in size than
single point diamond
dresser, so they are
much economical.
Cluster type diamond
dressers give
rapid-dressing and
produce a consistent
even surface on the
grinding wheel.
These dressers are
resistant to shock
and impact.
The dressing face of
the cluster type
diamond dresser
should be set at an
angle of 90° to the
grinding wheel so
that all the diamond
points are in
contact at the same
time.
Depth of cut per
stroke of the
dresser: 0.01-0.05
mm max.
Feed rate - in mm
per revolution:
0.3 - 1.5 mm max.
Finer infeeds &
smaller cuts will
produce higher
surface finishes.
Normal wheel speeds
should be used.
An adequate supply
of coolant should be
used both before and
during the dressing
operation, in order
to prolong tool
life.
