The grinding pattern depends upon the surface being treated.
Depending on the required surface finish specified, the tools (Diamond Wings),
will have to be changed in order to produce the best result. This may be done by
simply comparing the individual results of the tools.
For grinding applications, use the left-right switch of the machine every 330 sq.
ft. (100m
2
) to change the rotation of the grinding head). This will also provide a
longer life of the diamond tools, since they will wear down more equally.
Please note that this is NOT recommended for polishing applications.
Changing the rotation of the heads will result in large scratches that are difficult
to remove.
In the last 2mm of the diamond tools there is a loose buffer material (no
diamond inside), changing the rotation helps ensure that the diamond tools do
not wear in such a way that diamonds are left on one side of the grinding disc
and the other side the diamonds are completely gone.

7.10 INFLUENCES ON THE GRINDING PATTERN
Check the grinding pattern after new or other types of diamond
tools have been fitted.
By doing this, the operator can best produce efficient work, as
well as save unnecessary wear and repair costs.
