Wheelabrator’s SRS-4 machine can peen a
pair of springs in only 16 seconds, resulting
in an output of up to 450 springs per hour,
with blast cycles of neighbouring chambers
overlapping (depending on condition and
type of parts, production methods, peening
requirements etc.). The new SRS-4 at Rözmas
achieves a much improved and more
consistent quality.
Loading and unloading can be carried out
by a robot, manipulator, automated module,
or - as is currently the case at Rözmas -
manually. The machine therefore lends
itself to seamless and flexible integration in
highly automated production lines.
The machine can accommodate coil springs
with a maximum uncompressed length of
600mm and a minimum compressed length
of 150mm. Four powerful, indirect-drive
Wheelabrator U70 blast wheels with 22kW
each then blast the springs from all sides,
thanks to variable worktable rotation speeds
between 24 and 45rpm.
Tolga Yalgi, Managing Director at Rözmas,
comments: “We’re delighted with the
performance of our new spring peening
operations. We manufacture suspension
springs for the big names in automotive,
which means our processes have to be
exceptionally good and consistent. Peening
is a key process to ensure a long life and
reliable performance of each spring. The
new machine from Wheelabrator gives us
the assurance we need to offer the best
quality to our customers. In addition to a
much more efficient and precise peening
operation, the SRS-4 also uses less energy
and offers better overall machine safety
than our previous process.”
Rözmas placed the order for the new machine with
the Wheelabrator technology centre (TC) in Zürich
towards the end of 2015 and received the SRS-4
in July 2016. The machine was commissioned in
Gebze Kocaeli, Turkey, by a small team of engineers
from the Technology Center in Zürich. A full hand-
over followed in autumn 2016.
