Polygonal clamping delivers results in
turning applications
F
or years, customers have
been using TRIBOS polygonal
clamping technology to achieve
excellent results in applications such
as micro cutting and to lower tool
costs. With TRIBOS ER, SCHUNK is
now bringing the patented technology
of polygonal tool clamping to sliding
and fixed headstock lathes and rotary
transfer machines. Pilot users, such as
Zisterer Präzisionsdrehteile GmbH in
Villingen-Schwenningen, Germany, are
impressed. The company has reduced
machining time in demanding milling
applications by one third while signifi-
cantly improving surface quality.
There are good reasons why SCHUNK
is now unlocking the potential of
polygonal clamping technology for
lathe chuck technology. For one, the
requirements for sliding headstock
10
lathes are constantly growing. At
the same time, customers are facing
considerable pressure to lower prices,
particularly for high-volume parts.
For Zisterer Präzisionsteile GmbH in
Villingen-Schwenningen, SCHUNK's
decision to standardise the TRIBOS ER
came just in time. The manufacturer
of complex hydraulic components
was regularly experiencing process
disruptions due to tool breakages
as tools with a long overhang and
cutting diameters of 2mm could not
withstand the vibrations that occur.
Halving the speed was the only way to
ensure the process stability required
for high-volume production. Instead of
12,000 to 15,000 RPM, the company
had to accept speeds of 6,000 RPM
and the resulting reduction in cycle
time.
