Obaji Group is a leading company in the world in
manufacturing import and export of building materials start in
1968 by Dr. Obaji Father of the stone & marble and
granite, the first man export marble by container from Italy
to Saudi Arabia¡¢America¡¢Asia¡¢Africa in the world

| Production process |
The marble and granite manufacturing process is quite
simple as a general idea, but the peculiarity of each material
and its own fragility impose severe rules in the control of
every single working phase. |

| GANGSAWING |
|
Slabs of different thicknesses come out sawn from each
block by the use of diamond blades set on a power loom through
vertical gangsaws working at a sawing speed varying from the
4cm/h for the hardest granite to the 40cm/h for the softest
limestone.
The cutting speed and the sawing characteristic
of the diamond blades are differently set every time on the
basis of the demanded thickness and of the phisical and
technical peculiarity of each stone, so as to avoid the
collapse of the block during the gangsawing. |
| SLABS LINE POLISHING |
The stone slab is naturally mat, to make it brilliant
you have to polish it by a surface abrasion process.
The
first step of this phase is setting each slab properly on the
line, than washing it at a high pressure in order to clean
every trace of dust. The roller conveyor carries on the slab
into a oven-drying section, then all the resin and glue
residue are removed. After oven-drying the real polishing
activity begins: while carried over the roller conveyor the
slab is subject to the rotating pressure of the polishing
heads set in increasing order of sharpness. The final wax and
the quality visual control complete the polishing
manufacturing phase.
Coming out from the polishing line
each slab is protected by a plastic film and recomposed in the
original block, in order to preserve the colour uniformity of
the parcel.
Polishing is just one of the surface finishing
treatment for marble, granite, limestone and travertine, even
though it is the most employed, the other frequently used
surface finishing treatments are: |

|

|
| CUTTING |
|
The cutting phase is the most various since the final
product can assume the most different shapes customized on
each client's specifics.
Cogemar has 4 cutting machines for
diamond disk cutting and an automatic CAM moulding
machine. |

|
| "CUT-TO-SIZE" POLISHING |
|
It is often necessary to repolish pieces after their cut
to make them perfect. A special machine is dedicated to this
aim. |

|
| FINAL QUALITY CONTROL AND PACKAGING |

Making remarkable projects imposes a severe quality
control of manufacture and materials, so that each piece of
product receives the finishing thouch by hand and it is marked
on its back by its identificative number so as to be properly
set in the assembly plan of each project; then the pieces are
packed in wooden crates made on purpose and protected by
polystyrene sheets and/or plastic film. |
