ised by excellent fatigue strength, ideal chip
flow and precise concentricity. Coordinated
down to the last detail Despite its nega-
tive design, a key feature of the THETAtec
25N Feed is the positive cutting geometry
of the tools, which ensures easy cutting.
‘Thanks to the explicitly coordinated milling
geometry, this also applies to HFC milling
in full grooves,’ adds Schwaiger. Specially
arranged radii across the cutting edge en-
able optimum absorption and distribution
of the axial cutting forces. This means that
considerable tooth feeds (fz) of up to 1.4
mm are possible during high-feed milling,
even with a plate size of 09. Thanks to the
coordinated
clearance areas, it is also possible to ramp
into the solid material linearly and helically
without any compromises. ‘At the start of
the new development, it was extremely im-
portant to us not to lose any machining op-
tions here,’ emphasises Patrick Schwaiger.
Wide variety of cutting materials for a
broad range of applications
The exceptional performance of the
THETAtec 25N Feed milling tool systems
and their suitability for a wide range of
applications are also made possible by a
variety of cutting materials that are well es-
tablished on the market. One highlight here
is the proven Boehlerit fine grain grades
in combination with high-tech HIPIMS PVD
coatings.
At the start of the new launch, Boehlerit
is focusing on a total of 5 cutting materi-
al grades in order to be able to machine
materials from the P, M, K, H and S material
groups in the best possible way.
The new high feed system is available as
a shell milling cutter in diameters from 40
to 100 mm for insert size 09, as a shank
milling cutter in diameters from 25 to 32
mm and as a screw-in milling cutter in
diameters from 25 to 42 mm. As with the
DELTAtec 90P Feed, the THETAtec 25N Feed
system also features axially and radially
optimised tools with different numbers of
teeth and the proven uneven pitch to gen-
erate stability and reduce vibrations to a
minimum. The screw-in milling cutters can
also be used with solid carbide extensions
up to projection lengths of 300 mm.
The innovative
THETAtec 25N Feed
tool system achieves
significantly higher
cutting rates,
ensuring maximum
performance and
efficiency in use.
