now range from 0.5 to 60 mm.
From the trial to the purchase
The new R425/4600DA continuous-flow
vibratory grinding plant from Rösler has
been in successful operation at Schösswender
since January 2018 in a completely
enclosed sound-insulating cabin,
with care and maintenance constantly
available from the producer. “The two
companies have been working together
for twelve years now,” Gaugusch praises
S. SCHÖSSWENDER WERKE
As one of Austria’s leading metal casting
and processing companies,
Schösswender sets worldwide standards
for high-quality cast-iron
developments and solutions – from
batch size one to mass production;
through design consulting, casting
simulation, the hardening of aluminum,
and X-ray inspection; to prototype
construction and surface treatment.
The company, based in
Litschau, focuses on the rail sector,
responsible for more than half of the
company’s sales.

the partner company. “Leopold Haubenberger
comes round within a few days of
receiving a message.” Further development
of the consumables, as well as the
water supply and output, are the main
topics that are discussed again and
again. “The plant must be well set up in
process terms – then it covers the costs,”
adds Robert Halke from a marketing
point-of-view. “The topic of waste water
is also important, both ecologically and
economically.” In continuous flow systems,
after CNC machining vibratory
finishing frees the cast aluminum components
of burrs and structures that are
not part of the component. “The plant is
currently running in one-shift operation
but we could use two-shift operation,”
Gaugusch stresses the capacity reserves.
“Due to intensive automation, one
employee is sufficient to operate the
plant.” Only slots and the insides of
threads are still manually deburred, but
all the exterior burrs are removed
mechanically with the grinding bodies.
Worldwide focus on railway
vehicles
The R425/4600DA is fully automatic: the
parts are inserted and, depending on
the casting material, vibratory finishing
takes place using plastic grinding
