should I use a DiaTiger® Diamond Coated cutting tool?
DiaTiger® Diamond Coating has increased
tool life 10 to 20 times and more over uncoated tools with faster
material removal, more reliable unattended high precision machining
and reduced use of coolants when machining difficult to cut non-ferrous
composites and metals.
does DiaTiger® Diamond Coating improve cutting tool performance?
DiaTiger® Diamond Coating has all of the
properties of natural diamond including extremely high mechanical
hardness, strength, resistance to chemical corrosion and thermal
conductivity in addition to a very low coefficient of friction.
All of these properties contribute to the capability of diamond
to improve tool performance.
are typical application examples where DiaTiger® Diamond Coated
tools are used today?
Graphite & Hard
|EDM mold electrodes
Aluminum Silicon Alloys
Carbon Fiber Composites
|Aircraft wing skins
Fiber Glass Reinforced
|Circuit boards, fiberglass boats
Green & Bisque-Fired
Solid & Reinforced
Metal Matrix Composites
|Brake system components
|Mold cavities and components
|Valves, screw machine products
DiaTiger® Coated tools be used to cut steel and iron containing
No, the friction and heat from cutting
ferrous materials starts a chemical reaction causing the carbon
in the diamond coating to diffuse into the iron material. This
chemical wear of the diamond causes premature failure of the coating
when cutting ferrous materials.
cutting surface speed be increased when using DiaTiger® Coated
Yes, in many applications surface
speeds can be increased two to three times with significantly
longer tool life compared to uncoated tools because the diamond
coating protects the tool against abrasive wear, heat and chemical
does the increased cost of a DiaTiger® Diamond Coated tool
compare to increased tool performance?
The increased cost of a DiaTiger®
Coated tool will be paid back many times over in a single use
from improved productivity. Total machining costs with DiaTiger
Coated tools are dramatically reduced because of faster material
removal, longer tool life, reduced machine downtime, reduced coolant
use and the ability to perform more reliable unattended high precision
tools can be coated with DiaTiger® Diamond?
Most all solid carbide inserts,
blades, drills, end mills, taps, reamers, countersinks and other
shank type round tools can be coated. The carbide grade used to
make the tool should have cobalt content of 6% or less with a
1 to 3 micron grain size.
Cutting tools made of high speed steel and brazed tip tools cannot
be diamond coated because of the 1,500° F (815.5° C) temperature
of the coating process.
DiaTiger® Diamond Coated tools be resharpened and recoated?
is the difference between DiaTiger® Diamond and diamond like
No, this is not recommended. Resharpening
the super hard DiaTiger® Diamond is very difficult and the
coating process does not work well on a surface that is partially
coated and uncoated.
DiaTiger® Diamond has all
of the properties of natural diamond including extremely high
hardness, strength, thermal conductivity and resistance to chemical
corrosion in addition to a low coefficient of friction. Diamond
like coatings (DLC’s) consist of amorphous carbon with about
one-half the hardness of crystalline diamond and provide much
less tool life in cutting hard abrasive materials.
