"PCD" tools consist of a layer of Man Made* diamond
crystals bonded to each other and to a cemented carbide
substance. This combination of tool materials is possible
through a sophisticated high temperature / high pressure
process developed over the years by the technical staff at
General Electric Company.
*Random orientation of the diamond crystals means hardness
and abrasion resistance are uniformly high in all directions.
*Crystal to crystal bonding of the diamond layer
significantly reduces the chance of gross fracture under
*The tungsten carbide substrate provides strong support for
the diamond layer to further increase impact resistance.
*The diamond layer is flush with the substrate (no
overhang) to expedite tool fabrication.
*The diamond controlled manufacturing process means
physical properties are very consistant from blank to blank.
Tools made with COMPAX blanks have achieved impressive
results machining a wide range of non-ferrous metals and
Presintered tungsten carbide
"PCD" tools have significant performance advantages over
cemented tungsten carbide tools. Typical improvements include
tool life, better control over part sizes and surface
finishes, greatly reduced cost per machine part, and
dramatically higher machine productivity.
"PCD" tools are also replacing tools made with single
crystal natural diamond...particularly where impact is high
due to interrupted cuts. Significant performance increases are
seen over the life of several tools because the properties of
"PCD" tools are much more consistent then natural diamond
tools. Also, of course, natural diamond tools are much more
susceptible to accidental impact damage.
Polycrystalline diamond (PCD) inserts consist of a layer
of diamond integrally bonded to a standard or non-standard
carbide-inserts substrate. The diamond layer provides high
hardness and abrasion resistance, whereas the carbide
substrate improves the toughness and weldability.
PCD Inserts are used in CNC turning operations for
finishing PRECISION non-ferrous material parts. A highly
polished or "diamond" surface finish is achieved when using
