Full and half sets of diamonds
By changing the way the diamonds are set-up on the
diamond holder discs, an operator can signi cantly ef-
fect the performance of the machine and therefore, the
nished product.
HALF-SET OF DIAMONDS
When the diamonds are set-up as a half-set, they tend
to follow the surface of the oor. Similar to a tripod for a
camera, which can be placed on an uneven surface and
yet still nd a stable footing.
The half-set diamond con guration should only be used
when a at oor 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 oor. If the oor has undu-
lations, the machine will grind the high areas yet miss
the low spots (unless the high areas are ground down
rst).
The full-set diamond con guration should be used when
a at oor nish is desired.
