Full electric
The last
word in sheet metal and tube fabrication processes are “full electric” machines
to remove any hydraulic units. As the cars electric machines started new era
for general power equipment fabrication. The reason is quite important – the
increase of the precision, control for every movements with the elimination of
electricity consumption (which is quite expensive in Europe) and reduction of
maintenance procedures. Moreover the electric is green technology with the
absence of any waste of dangerous contamination liquids.
There are
no minuses for the electric technology but some blocks – for example more big
investments for the equipment and limited powers and forces for the offered
machines on the market. Today “full electric” is fashionable and
high-technology term for all tube bending machines with CNC, press brakes with
low and medium forces, CNC punching presses for sheet metal. “Fast, precise,
safe, green” – all the words are actual for full electric machines marketing.
Should we
invest for “full electric” machine? It depends. Every investment is the subject
for calculation of economy, production, possibilities and functions. It is the
present technology today, very modern and innovative but the production factory
is not the place to use the “fashion” but to get the economy stable flow with
the use of different machinery. With some applications for higher precision
“full electric” could be not necessary but very recommended but for other thing
everything is in hands of the managers. Small electric press brakes have very
good feedbacks to proceed with small parts in high production and the
replacement of the punch press can reduce in thousands the invoices amounts for
electricity.
Servo-drived
electric machines are also 100% controlled with CNC. It is important point for
accuracies, complicated setups and important applications. Moreover the market
started the turn for “full electric” so we should follow the world, right?
