83,000 operating hours and now as good
as new
For Maschinenfabrik Niehoff, top quality,
durability and value retention have always
been the priorities when it designs and
produces its machines and lines. Niehoff
machinery which has been in operation
for decades is worth reconditioning and
being brought up to the latest technical
standards.
With special measures, Niehoff upgrading
specialists are even able to increase the
machines’ original level of productivity.
In this way, Niehoff Original+ After Sales
has been optimising machines and lines
for decades. One example is the full
reconditioning of a multiwire drawing line
which was supplied by Niehoff in 1996.
The line, an MMH 101 multiwire drawing
machine with integrated RM 140 contin-
uous annealer and an S 631 spooler
designed for the simultaneous drawing
of 24 copper wires, already has 83,000
hours of operation behind it and is used
after reconditioning in one of the user’s
non-European plants.
The first measure taken before every
machine is reconditioned is an inspection
of the line by a Niehoff engineer on-site.
After this the Niehoff specialists discuss
with the user all the reconditioning
work which is necessary, and draw up a
quotation for the work.
In the present case, the drawing line was
transported to Niehoff’s headquarters
in Schwabach, Germany, completely
dismantled, cleaned and stripped of
its paint. After each of the assemblies
had been checked, the machines were
repainted. The bearings and sealing
flanges were completely replaced.
In addition, the annealer was completely
refurbished and the line’s electrical
components were adapted to the power
network of the country in which it is to be
used in future.
Given the hot climate where the line
is to be used, an additional cooling
system was installed in the control
cabinet.
Following assembly, a test run and a
pre-shipment inspection by the user, the
line was delivered to its new point of use
in North America, installed and put into
operation by Niehoff engineers.
Niehoff specialists are best qualified
to recondition the machines and lines
manufactured at Niehoff with maximum
expertise and put them back into tip-top
condition.
The Niehoff specialists who are involved
in a reconditioning project are fully
familiar with all aspects of the underlying
machine technology.
Moreover, they have access to well-
maintained documentation and machine
data. Most of the spare parts required for
each reconditioning job are produced
in-house on cutting-edge machining
centres to OEM quality.
Where third-party components are
brought in, Niehoff makes sure that
they all meet the high Niehoff quality
standards.
