TOOLING WORKING TOGETHER FOR GREATER BENEFIT
monitored and optimised, different options
are offered by ToolScope.
The Schuster nxt vertical turning centre is
a precise and highly exible machine concept
that can be perfectly tailored to customer
requirements. And Ceratizit has made a
positive impression as a partner in that
successful launch.
Concludes Rühle: “We really are
impressed by the tools that the project
engineering team has put together for us.
We are so convinced by them that we
recommend Ceratizit tools for each new nxt
purchase. Depending on the machine
con guration that has been ordered, Ceratizit
puts together an individually tailored tool
package to meet customer requirements.”

milling system that allows inserts to be
changed in the machine. Thanks to state-ofthe
art Dragonskin coating technology, the
precision-ground indexable inserts are
extremely stable and offer smooth cutting,
as well as soft cutting for optimum surface
quality and signi cantly longer tool life.
The 20 to 40% higher cutting speeds –
subject to material and its properties – of
milling cutters from the latest WNT SilverLine
generation also played their part, while the
service life increased by 30 to 40%. In
addition, the new SilverLine tools are quieter
and reduce the burden on the machine.
EcoCut is another tool employed; this is a
product designed by Ceratizit to make four
different machining operations possible with
just one tool. Says Ambruster: “The
advantages are obvious: the different
machining processes are combined and
there is no need to change tools, which
greatly reduces the set-up time and
increases machine utilisation.”
And since three carbide grades with
Dragonskin coating have been introduced,
an even broader range of materials and
different applications are now possible,
says Ceratizit.
WTX HFDS, the world’s rst high feed
drill, showed how its four effective cutting
edges can deliver, too. Machining time with
the WTX HFDS is reduced by up to 66%
compared to the usual market standard for
two-edged and three-edged high feed drills.
“It was used in 10, 12 and 16 mm
diameters for the Schuster component and
came up with the best times. Despite the
fast pace, the Schuster nxt achieved the
best surface quality in conjunction with the
solid drilling console directly on the machine
base. And what about tool life? Last but not
least, there are four spiral coolant holes
making sure that the cutting edges are
always optimally cooled and that the WTX
HFDS is notable for its long tool life,”
stresses Baur.
TROCHOIDAL TURNING
A novelty employed is trochoidal turning,
a technique well known in milling but less so
for turning. “Up to now, trochoidal turning
has rarely been an issue in production halls,
simply because there was no relevant CAM
software available. But now the tide has
turned, thanks to hyperMILL and MAXX
Machining from OpenMind
www.is.gd/lamemu : We have now expanded
the proven concept of trochoidal milling to
cover the rough machining of all turned
parts, as well as developing trochoidal
turning with CAM programming – and also
implemented this in the Schuster nxt,”
says Baur. The technology delivers shorter
cycle times and uid machine movements in
parallel with longer tool life, increased
process security and less wear.
A further technology from Ceratizit that is
employed with the Schuster nxt is monitoring
system ToolScope (see Machinery, July/
August 2020 – www.is.gd/guvilo ). The
system continuously records signals from
the production process, with this data
visualised and used to monitor and adjust
the machine. Depending on what is to be
