Diamond
Characterization Technology:
The Optimum Saw Diamond for Your Specific Application
The growing sophistication of diamond tool manufacturing and applications has
created the need for a better understanding of the relationship between physical
properties of diamond and tool performance. Diamond Innovations meets this challenge
through the consequent use of a range of diamond property measurement techniques
in advanced crystal property analysis and development.
Diamond Innovations does this with one precise goal in mind: To provide tool manufacturers
worldwide with an easier, more quantifiable means of selecting and purchasing
the optimum saw diamond grades for their specific application needs.
Conventional
measurements of bulk characteristics of saw diamond
Thermal Strength and Stability (TI and TTI) Provide a relative indication of
average bulk diamond strength, but are no longer sufficient to accurately measure
the strength properties of a diamond crystal. These techniques only fracture the
weakest crystals in a population, providing no quantitative measure of the strength
of the stronger, harder working crystals. Also TI and TTI testing does not provide
information on the distribution of strength across a crystal population.
Superior
Measurements Designed by Diamond Innovations: Compressive Fracture Strength Test
(CFS) Overcomes Limitations of Conventional Testing
CFS is designed to more closely resemble the dynamic impact loading a crystal
experiences during a cutting application. The test provides an improved average
strength measurement as well as information on the distribution of crystal strengths
within a population. Strength is measured in terms of compressive force to fracture
the crystal. The resistance to fracture of a saw diamond is a key parameter in
the performance, particularly in high impact applications. CFS testing also provides
much more appropriate quantitative measure of strength across a population of
diamond than the conventional bulk TI and TTI tests.
Compressive
Fracture Strength Test
Diamond Innovations’ Compressive Fracture Strength test is designed to more
closely resemble the dynamic impact loading a crystal experiences during a cutting
application.
Compressive
Fracture Strength
Two samples of high-grade saw diamond with virtually the same TI and TTI are subjected
to the Compressive Fracture Strength test. As the results show, the CFS test provides
diamond manufacturers with a more discriminating means of classifying diamond
grades. The test also provides a quantitative measure of strength across a population
of diamond rather than the average bulk strength measurement provided by TI/TTI
testing.
