Rally. High-performance components
made of aramid, carbon and glass fibre
composites for this project, as well as
for exclusive sportscar models of leading manufacturers and prototypes, are
produced in the Nürburgring works -
around 2500 units per project for series production alone every year. The
process starts with the CAD concept
and continues through mould making,
make-up of the parts right up to hardening and joining, and ends with the
final machining in the form of component trimming. Coating and quality
assurance in the dust-free measuring
room are the last two steps in the process.
ogy from Maka, in particular in the
component trimming step. A total of
5 machines were purchased in 2012 at
the time the new production facility
was set up. The plan provided for their
use as model-making machines. In addition to machining quality, the focus
was also on flexibility. In the meantime, the team has gained many years
of experience with Maka technology.
The uniform control concept for all
the machines has proved to be very advantageous. The team does not need to
worry about which machine they use to
produce which part. They can choose
freely between the two MK 7 S, the
MM 7 T and the two BC 570 machines.

The necessary preconditions are created by the "gigantic" working range
of the machines. On the BC machines,
the team have a 6 m x 3 m x 2.5 m working area and can produce huge moulds.
This is an important criterion, because
parts such as car bonnets, roof shells
and tailgates have to be machined. On
the MM 7 T, on the other hand, carbon components such as spoilers and
rear diffusers are produced in series.
The solution must be able to combine
large dimensions with short lead times.
In this respect, 2m x 2 m x 2 m is also
fantastic. With this working area, it is
possible to hold two to three jigs on
the table and hence achieve high productivity.
The team leader for CNC machining
also appreciates the integrated vacuum pump on all the machines that allows even self-manufactured jigs to be
used without the need for major modifications. The high precision of the
machines rounds off his very positive
opinion of Maka technology.
