Tightening up procedure tightened
May 1st 2008 MAHLE Powertrain has
used Crane Electronics'
torque control products for
over a decade and is
upgrading its equipment
with the latest generation of
Crane products. "We
assemble engines and
typically check one in 50
engines per shift basis to
ensure high-quality
tightening of nuts, bolts and
fasteners," explains Dave
Burton, MAHLE production
engineer. The correct level
of torque is crucial in the
automotive industry: too
little and joints may loosen
while over tightening can
mean fixings are taken past
their yield point, which can
lead to early failure of the
bolted joint.
MAHLE has added two
Crane products to its quality
systems, the ProWrench
Opta and the Torquestar
Opta. The ProWrench Opta
is a digital torque wrench
which is compact, portable
and highly adaptable. The
TorqueStar Opta is a data
collector incorporating
multiple stationary
transducers, joint kits, a
printer and a tool reaction
