Strongpoint of using diamond abrasives (brick/Fickert):
Saving electricity: diamond brick can be used to grind stone
with less power because of its sharpness. This can reduce
the stress of grind head, thereby reduce machine' abrasion
and stone's dilapidation.
High efficiency: using diamond brick can raise the
transmission speed of conveyer belt; thereby improve the
efficiency for its sharpness and abrasion resistance.
High luminosity: using diamond brick can improve stone
luminosity more than 10 degree. For adopting advanced
technology, diamond brick can totally avoid the
unstabilization of brick quality that caused by magnesia
activation reduction and conservation condition's change
during the production. And possibility of causing nick and
unstabilization of luminosity reduce because that the
examination and transportation of diamond production are
more rigorous than that of magnesia production and the
uniformity of diamond granularity is far better than that of
luminosity.
High quality: diamond brick own high quality because
computer controlled production equipment and technics are
used in the production. However, the production of magnesia
is still adopt simple manual work and the production period
would prolong more than one month, these affect the quality
of products.
Stone surfacing is the whole range of
operations which, after sawing or milling, give the surface
its final polish. They take place as follows:
- Roughing (or dressing)
which removes the flaws caused by sawing;
- Smoothing, which
eliminates the scratches left by the abrasive during the
previous operation;
- Polishing, which gives
the stone sufficient finish to take the final glazing;
- Glazing, the final
operation using a flat plate, in which the diamond plays no
part.
The
development of new bonds and
impregnations has had the effect of extending the use of the
diamond tool to stages subsequent to surfacing, i.e. smoothing and
polishing. This development is linked to the advantages which the
diamond shows over silicon carbide. They are:
-
To reduce
the time and the necessary stages to obtain a finished product;
-
To reduce
tool replacements due to a longer tool life;
-
To avoid
inconveniences of silicon carbide tools where loose grains earlier
released tend to scratch a surface already treated with finer
grit size.
How Many Heads Equipped With Diamond
The best results can be expected by replacing conventional
shoes on the 3-5 first heads of the line.
The Advantages of Using Diamond Instead of Conventional Tools
Productivity
Increase of 10-20% of the line speed.
Reduction of dead times
The replacement frequency of diamond shoes is very low.
Moreover, these reduced operations increase the safety of
workers.
Reduction of
Carbo stock (for a similar production, the volume/head of
carbo is 250 times more important that the one for the diamond tool
Carbo shipment costs
Cleaning frequency of machine.
Utilization, easiness & flexibility
Reduced operational costs
-less energy consumption (20 to 25% per
head) because pressure on shoes is reduced to 2kg/cm2
-less strain on the heads, therefore less
maintenance
-only 1 operator for 2 to 3 polishing lines
-reduction of required number of heads
-less plate breakages (because of reduced
pressure)
Pollution free
Storage conditions
Conventional tools must be kept dry and are sensitive to temperature
variations; not the diamond sectors.
Quality
The quality of the polished tiles is the highest quality and even better
than conventional shoes when the granite is porous.
