Case hardened steel is a unique material coupling
a hard and wear resistant outer skin with a tough
impact resistant core. The result is a material with
desirable properties for harsh environments such
as automotive gearboxes and drive train components.
The nature and use of components produced
with this material demand high and repeatable
machined tolerances, surface finishes and
surface integrity. To meet these demands PCBN
cutting tools have evolved to offer a cost effective
and reliable machining solution for case hardened
Seco has been very active in the machining of
this material for many years, offering class
leading grades such as CBN050C and CBN160C.
We are continuing to demonstrate that through
grade and format innovation we are able to meet
your ever increasing demands.
