Automatic tool changers
increase bending productivity
by Nestor Gula
As fabricators continue to look for ways to
improve productivity in an ever-increasing
competitive environment, they’re turning to
automation. For press brakes, that typically
means automatic tool changers (ATCs).
“The tool changer may not be faster than
an operator changing the tools, but the
beauty of it is that the operator can then do
other jobs while tools are being changed,”
says Marcel Fink, TruBend sales product
manager for TRUMPF Inc. With this,
overall setup time can be reduced by up to
50 per cent. The productivity gain depends
on how the shop was organized before and
whether they were taking advantage of
technologies such as automatic tool clamping
and optical setup aids.”
Scott Otten, bending product manager for
Amada America Inc. estimates a fabrication
shop can save about 20 minutes on average.
The main reason to have an automatic tool
change system on a press brake is to “reduce
the amount of non-value added time.”
Bill Bossard, president of Salvagnini
America suggests asking what percentage of
the day is a press brake producing a part. “You
get a wide variety of answers, but typically
people that have looked at their own shops
have told me that it’s less than 20 per cent of
the day that the machine is bending a part.
