PCBN
Our DURATEC PCBN grades are precisely engineered to meet the requirements
of manufacturers of highly loaded turning, milling, and grooving tools.
We offer high-quality PCBN grades (polycrystalline cubic boron nitride)
that have been specifically developed for demanding machining processes
in the hard machining of ferrous materials.
PCBN is one of the most high-performance cutting materials in modern manufacturing,
distinguished by an exceptional combination of extreme hardness, high thermal stability
and outstanding wear resistance. This makes PCBN ideally suited for machining hardened steels,
sintered steels, cast iron, powder metallurgy materials, and other difficult-to-machine materials.
Thanks to homogeneous grain structures, reliable bonding matrices,
and reproducible material properties, our grades provide consistently
high cutting-edge stability, long tool life, and maximum process reliability,
even at high temperatures and under extreme cutting conditions.
With many years of experience and technical expertise, we support tool manufacturers in realizing efficient, cost-effective, and highly precise hard machining processes in a reliable manner.
DURATEC supplies PCBN materials in application-optimized grades that are perfectly matched to specific removal rates, surface finish requirements, and tool geometries.
