industrial revolution was a catalyst in the rapid growth
of the auto and heavy machinery industries.
As more and more `difficult-to-grind' materials and alloys
were being used by these industries, the demand for higher
quality, effective, and durable machine tools for cutting,
grinding, and machining such materials continued to escalate.
As a result, superabrasive diamond and cubic boron nitride
(CBN) tools were invented to meet the needs of these industries.
Today, development and use of these specialized tools has
expanded to a variety of industries as new applications
are constantly being discovered.
