Swisslan S.L.
ED wire cutting in time
with the incoming orders
Swisslan S.L. is a typical jobbing
EDM business in which the dayto-day
business determines the
work scheduling. Constant deadline
pressure requires high flexibility,
both on the staff and the
machine side. Production sequences
must be geared exactly
to the machine and operator capacity.
That is why Swisslan S.L.
decided on an Agiecut Classic V2,
as this ED wire cutting machine
meets these requirements best:
- Rapid data input
- Great selection of cutting
technologies
- Rapid set-up
- Rapid wire change
- Lowerable tank for machining
in the bath
- Rapid insertion of express jobs
- Reliable process with all
geometries.
for the quality targets. So Angel
Ibarluzea can choose whether
the machining is to be carried
out quickly, with the highest precision
or both. In the case of the
devices for the extruded sections,
several of the generator’s functions
then take effect: «AWO» -
Advanced Wire Offset – compensates
for the wire wear and
flushing. «Wire Bending Control»
determines and corrects wire deviations
resulting during the
process. «Variocut» automatically
adjusts the output in the case of
stepped workpieces. Functions
which are not, it is true, visible,
but which do show on the workpiece
and in the time required for
a job.
The autonomy for
unsupervised operation
On account of the frequent
clamping and unclamping operations,
setting up and individual
data inputs involved, jobbing EDM
orders presuppose the presence
of an operator in most cases. And
yet there are orders where high
machine autonomy is also decisive.
Swisslan S.L. had to cut six
extruded profiles with 1 main cut
and 3 trim cuts from a 100 mm
high aluminium block. Here
«Agiejet» for reliable wire threading,
the standard 25-kg wire
spools as well as the long service
lives of the filters proved their
worth - especially in the case of
aluminium machining jobs. For
Swisslan S.L., Agiecut Classic V2
is thus the classic «all-rounder»
of ED wire cutting.
«Teccut» makes technology proposals
from a few inputs. Thanks to
the state-of-the-art Vertex technology,
Angel Ibarluzea, joint owner of
Swisslan S.L., can then select and
activate the best possible machining
technology.
Various devices for machining extruded
profiles which are produced
by Swisslan S.L. using ED wire cutting
and as a complement to that
milling all out. All three workpieces
are made of hardened steel and have
a surface roughness of Ra 0.4 µm
and a contour tolerance of ± 5 µm.
Antton Osoro, joint owner of Swisslan
S.L., checks the progress of the
cutting of the starting holes which
are needed for ED wire-cutting jobs
on an Agiedrill. Small electrode
tubes of from 0.3 mm to 3 mm can
be used for a depth of up to 200 mm.
In jobbing EDM, every machining
step must be right. This maxim
begins at Swisslan S.L. with the
data input for the ED wire cutting
of a workpiece. Angel Ibarluzea
needs just a few workpiece details
for this: Height, form, material,
surface quality and accuracy.
«Teccut» then generates the best
possible technology and in addition
makes alternative proposals
