Diamond selection
The following section covers important factors to
consider when selecting the diamond segment you are
going to use for a given application.
Grinding disc set-up
The way diamond segments are set-up on the grinding
heads of the machine will also greatly infl uence the
performance of the machine, the productivity levels
and also the fi nished fl oor quality.
There are basically two types of diamond confi gura-
tions that can be used when using the grinder:
1. Full set of diamonds – when there are diamonds
placed
at each of the six positions on the diamond holder
discs
(see pictures above).
2. Half set of diamonds – when there are diamonds
placed
at three alternating positions on the diamond holder
discs (see pictures above).
Generally speaking, the faster a diamond segment
wears, the faster the productivity will be. By varying the
above factors, changes can also be made to effect the
following:
Scratch pattern.
Current draw of machine.
Flatness of fl oor (see next section).
Ease of operation.
