Diamond Types
The unique properties of
diamond
make it a leading choice for industrial tool use.
The
hardness
of diamond allows it to be ground and polished into very accurate and sharp cutting edges.
Check out our page with some
diamond facts
to learn more about what diamonds
Chardon Tool
uses in our wide array of tools.
Below, we will delve into different types of diamonds and other very hard cutting tool materials.
Natural
Natural diamonds are sought after by consumers for their beauty, ability to
refract light,
and their inherent uniqueness.
On the industrial side, diamond is sought after for its unique properties and their application to industrial processes.
We select only the best
natural diamonds for use in our tools to ensure we provide the highest quality products.
Our tools are less prone to breakage and achieve superior results in
surface finish
and
edge wear,
as a result.
This can be attributed to the knowledge obtained after years of experience and working closely with our customers.
Synthetic
Single crystal
synthetic diamonds
are grown in a laboratory from a small diamond seed.
They have similar properties to natural diamond but often have superior
hardness,
thermal conductivity,
and
electron mobility
than natural diamond.
Synthetic diamonds can be manufactured in a variety of colors as well as completely colorless.
We work with
HPHT and CVD synthetic diamonds
to create our tools.
Also, many synthetic
diamond tools
can be
relapped
just like their natural counterparts.
Polycrystalline Diamonds (PCD)
Polycrystalline diamond
(PCD) is composed of micron and submicron-sized diamond crystals that are bonded together under high heat and pressure.
A
PCD cutting tool
cannot produce the same form accuracy and
surface finish
as a
single crystal
diamond tool because of their
granular
nature.
PCD tools are often used for rough machining to near-net shape.
Final
machining
is typically completed with single crystal
diamond tools.
PCD tools are used to work on the
same materials
as single crystal diamond tools.
Cubic Boron Nitride (CBN)
Cubic boron nitride
crystals are the next hardest
cutting tool material
after
diamond.
Polycrystalline cubic boron nitride
(CBN) has a structure very similar to polycrystalline diamond (PCD).
A CBN cutting tool cannot produce the same
form accuracy and
surface finish
as a single crystal diamond tool because it is also
granular
like
PCD.
However, CBN is used to
shape many of the
materials that are
not diamond-friendly,
including hardened steel.
CBN tools are
typically used for machining to
near net shapes
before
final grinding or
polishing.
