each operated separately. Some press designs
encompass multi-axial pressing options.
The remarkable progress in press technology enables
the production of complex shaped inserts that are
characterized by variable corner heights. (fig.1)
This capability enables optimal cutting geometries
to be achieved, guaranteeing not only smooth and
stable machining but also the increased accuracy
of a machined surface. (fig.2)
Additionally, the advantages provided by the use
of modern CAD/CAM systems make it possible
to improve the design and the shaping parts of
pressing die sets. Also, the ability to simulate
the pressing processes related to new sintered
products, when they are at the beginning of their
design stages, allows further design amendments
and enhancements to be made.
Advanced new techniques, related to sintering
insert masters, improves process quality. The
gradient sintering of multi-carbide substrate
ensures a thin upper layer that feature high cobalt
content. This gradient layer produces an excellent
barrier against the development of cracks and
