CUSTODIAM, as close partner of
a major diamond tools manufacturer,
has built up a true science of diamonds,
enabling us to supply the most appropriate
diamond type, perfectly matching
any specific application.
Through sieving and sorting, synthetic
diamond grits are selected according
to their size and shape, already
defining several distinct qualities.
Colour and magnetic measurements
will provide additional information
in order to describe the various
Within our laboratory, a whole
series of tests and analyses are
also performed to better evaluate
every quality level, such as toughness
index (TI) and thermal
toughness index (TTI) or fatigue resistance.
Our scanning electron microscope
allows us to control the good tenue
of diamond grits within the bond
(as well as to evaluate its microstructure).
Our know-how in metallography helps
us to further analyse the structure
of metal bond segments for instance,
determining different components
and proportions used, or any defect
Synthetic diamonds can also be
treated in order to be used for electroless
Speaking of treatment, natural
diamonds are mechanically rounded
( spinning) and chemically polished,
after being sorted by size through
Polycrystalline products are also
being controlled in view of establishing
- PCD are submitted
to a test shocks, set up within
our laboratory, evaluating their
resistance to shocks.
- Whereas for
TSP products, the test will estimate
their wear resistance inside
a planetary which will induce a
wear phenomenon due to its rotating
