materials and purchased parts, and manufactures
the components. Only then the machine is
delivered and fully disassembled into its individual
parts. Schwarze-Robitec sandblasts all welding
components and the entire machine frame in
order to remove the old paintwork. All welding
seams are also checked. So whilst the machine
frame and the welding components are re-used, all
hydraulic and electrical installations are replaced,
including hydraulic piping, cables, control cabinet,
control technology and control panel.
In addition, the entire machine safety system,
including the CE components, for instance, is
newly installed during a general overhaul. This is
due to the fact that statutory safety regulations
have usually changed since the machine was first
put into operation. This is ultimately followed
by the assembly of the overhauled machine –
including the preliminary acceptance test at
Schwarze-Robitec’s site in Cologne and the
machine being put into operation at the desired
location – as is the case with a new machine. A
12-month warranty period is offered.
General overhauls are usually ordered by clients.
However, in some instances the manufacturer sells
a machine that has undergone a general overhaul.
This can be a particularly interesting prospect
for buyers if the machine configuration is ideally
suited to their performance requirements and they
are working on a tight budget. Since expensive
parts such as the machine frame and welding
components are re-used, an overhauled machine
is roughly one-third cheaper than a new machine.
And yet the buyer receives a product which is as
good as new with state-of-the-art technology.
Keeping an eye on a machine’s overall
condition
If a car suddenly starts to stutter and breaks down
on the road, this doesn’t mean that it is a complete
write-off. Perhaps it only requires a new oil filter,
new spark plugs or maybe even a new engine.
For tube bending machines, this is equivalent to
a component overhaul. If, for example, a new
pressure die assembly, a new swing arm or a new
bending head is installed, it is possible to get the
machine back up and running again. However,
