Innovations in carbide technology, coating design and
chip-flow optimisation have enabled the development of a new generation of
grades for steel turning applications. The combination of these technologies
has resulted in the high-performance and cost-effective steel turning grades
BCP05T, BCP15T, BCP25T, BCP35T and BCP40T.
The new Boehlerit steel turning grades deliver enhanced
performance and process reliability throughout the turning operation. A newly
developed combination of substrate and coating technologies significantly
improves tool life.
The BCP05T, BCP15T and BCP25T grades are particularly suited
to continuous cutting operations in steel, cast iron and stainless-steel
materials. The tougher BCP35T and BCP40T grades have been specifically
developed for turning applications involving interrupted cuts.
The newly developed BCP15T, BCP25T and BCP35T grades feature
an innovative two-tone CVD coating concept designed to withstand demanding
temperature loads and thermal cycling conditions while providing excellent wear
detection capabilities.
The coating combines the proven MT-TiCN layer system, which
effectively resists flank wear, with an ?-Al2O3 layer that protects the insert
from excessive temperatures and reduces crater wear. Wear identification is
further enhanced by a yellow TiN top layer on the flank surfaces.
The BCP05T, BCP15T and BCP25T grades are recommended for
medium application ranges involving high cutting speeds, long engagement times
and stable roughing operations. Meanwhile, BCP35T and BCP40T deliver strong
results at medium cutting speeds, particularly in applications requiring
enhanced toughness and process security.
The new turning grades are designed to address the growing
challenges encountered throughout the steel turning process. With a focus on
productivity, reliability and cost-effectiveness, Boehlerit continues to
position itself as an innovative partner for modern machining operations.
