Stress peening of automotive
springs: Rozmas boosts quality and
efficiency with new SRS- 4
Rözmaş Çelik San. ve Tic. A.Ş., a leading
manufacturer of automotive springs and
stabilizers, has invested in an automated
spring stress peening machine from
Wheelabrator to achieve the highest
production qualities faster. At Turkey-based Rözmas, the new SRS-4 replaces
an older, non-Wheelabrator spinner-hanger type
machine that had been modified to enable stress
peening. This older machine was unable to meet
increasing quality requirements and output
targets.
Stress peening means that a pre-defined load is
applied to each spring during peening, improving
its long-life fatigue strength and enabling a
lighter design. The new machine’s compact design is centred
around a “satellite turntable” with five separate
blast chambers with two satellites per chamber
that hold, compress and rotate one spring each.
This means pairs of springs are “clocked” through
the machine at a steady, continuous pace,
with loading and unloading of one chamber
happening while peening takes place in two
others.
The SRS-4 stress peening machine from
Wheelabrator ensures a fast and consistent
peening process with varying degrees of
automation, and is a well-established and trusted
solution for automotive suspension springs.
