PCD cutting insert
Sumitomo Electric Carbide
diamond (PCD) blanks in 1978, Sumitomo has
continually developed and expanded the product line
to offer finished inserts in a wide range of grades,
shapes and sizes. SUMIDIA inserts consist of a layer
of fine grain synthetic diamond crystals bonded to a
tungsten carbide substrate which is securely brazed
into the pocket of a standard size insert. A high
degree of diamond to diamond bonding is achieved
by an ultra high pressure-temperature process. This
crystal to crystal bonding provides exceptional hardness
and abrasion resistance.
Our closely controlled manufacturing process
produces unequaled consistency resulting in
superior tool edge quality.
SUMIDIA DA inserts and wipers are replacing
tungsten carbide and natural diamond cutting tools on
a worldwide basis. Use of SUMIDIA DA grades will
provide dramatically increased tool life, the ability to
hold closer part tolerance, and improved surface
finish.
New technological advances have given the
industry a new style of PCD insert. The optimum size
of PCD used in NF-DA2200 offers a less expensive
alternative when machining non-ferrous materials.
