Eder Engineering has a leading
position in advanced diamond and
PCD die working equipment, offering
universal flexibility and application, a
high degree of automation – even on
standard units – and highest possible
efficiency, particularly in machinery
for the reconditioning and production
of diamond and PCD dies.
While PCD dies play a major role in the
non-ferrous wire drawing industry, the
majority of ferrous wire is drawn using
tungsten carbide (TC) drawing die
tools. TC dies need totally different
working methods and machines for
their repair.
For the average TC die user, dealing
with frequent changes in die-bore
diameters and a wide size application
range, Eder has developed the
semi-automatic ETC-1/HF. This unit
is said to grind and polish both the
conical and cylindrical die bore
sections “in record time.”
Wire drawing plants dealing with
tungsten carbide dies in near identical
bore-sizes and/or similar stages of
wear, however, are more efficient
using fully automatic equipment.
In cooperation with AGIR-France, Eder
offers completely automatic machines
for all usual sizes of round tungsten
carbide wire drawing dies.
All operations are managed by an
OPLC combined with an intelligent
program. According to the type of the
TC die-nib material to be processed
and the kind of operation chosen,
the OPLC allows program adjustment
to optimise the production or
reconditioning of TC dies within the
indicated work range.
For processing TC dies of 1mm to
6.5mm diameter, model TCLD-C-CNC
for producing or reconditioning of
the conical die-portions is available,
while the other model TCLD-B-CNC
serves for a precise processing of
the cylindrical bearing. If required,
both TCLD machines can combine to
operate in an in-line mode, using an
intelligent robot connection.
Steel cord wire producers and other
special plants use many tungsten
carbide dies with small bore-sizes.
For these customers Eder-Austria
offers the high precision, easy to use
TCSD-CB-CNC that can work both
the conical die-portions and the
cylindrical bearing part in a diameter
range between 0.1mm to 1.5mm.
Precisely manufactured and well
maintained wire drawing dies,
whether diamond/PCD or TC, produce
longer uninterrupted runs, excellent
wire surface quality and improved
performance, leading to considerably
higher output. Any necessary change
of a die set in wire drawing machines
will usually cause a down time of
between 20 to 40 minutes. If die life
can be increased by 10%, this results
in a 10% increase in productivity.
