Five steps to zero-fault fastening
As joint fastening grows more complex, error-proofing be comes a
key factor for the profitability of your operation. The later an assem-
bly defect is identified, the more it costs to correct further down the
line. At worst, it could reach the end customer and result in warranty
claims and loss of goodwill. Leading the field for tightening
process control, Atlas Copco has defined five steps towards zerofault
fastening.

“Error proofed
production –
five steps to
achieve zero
fault
fastening”.
Step 1. To assure
a correct tightening
torque
The first step to zero
fault production is obtained by using an
assembly tool that delivers a precise
and pre-determined torque. However,
only the tightening torque is controlled
at this first step, operators and work
pieces are not yet involved in the monitoring
process.
Step 2. To assure
that all screws are
tightened
One of the most common
causes of a faulty assembly is the
fact that the operator simply forgets to
tighten a screw or makes a re-hit on an
already tightened screw. The remedy
against this possible error is to use an
REcontroller. It monitors the tightening
cycle and identifies a proper shut-off of
a tool.
