Full and half sets of diamonds
By changing the way the diamonds are set-up on the
diamond holder discs, an operator can signifi cantly ef-
fect the performance of the machine and therefore, the
fi nished product.
HALF-SET OF DIAMONDS
When the diamonds are set-up as a half-set, they tend
to follow the surface of the fl oor. Similar to a tripod for a
camera, which can be placed on an uneven surface and
yet still fi nd a stable footing.
The half-set diamond confi guration should only be used
when a fl at fl oor fi nish is not required.
FULL-SET OF DIAMONDS
When the diamonds are set-up as a full-set, they tend
not to follow the surface of the fl oor. If the fl oor has undu-
lations, the machine will grind the high areas yet miss
the low spots (unless the high areas are ground down
fi rst).
The full-set diamond confi guration should be used when
a fl at fl oor fi nish is desired.
The below table gives some examples of possible ap-
plications for the two arrangements:
