Perfect cutting technology for the perfect sports car

Each Pagani chassis is constructed from precisely 240 carbon-based composite components

ny secret. Depending on the required
stiffness and strength, close to ten different composite materials are used.
One of these combines titanium and
carbon fibre in a composite called
Carbotanium, developed and patented by Pagani. It is roughly six times
lighter than steel and provides the best
strength-to-weight ratio in the automotive industry. Cutting titaniumreinforced carbon fibre is extremely
challenging.

same machine using the pneumatic oscillating tool (POT), an air-driven tool
with an extended, 8-mm stroke that
provides the force needed to reliably
and productively process this type of
material.

Material savings of more than 20%
Pagani carbon fibre components are
strictly made to order. The state-ofthe-art Zünd nesting function ensures
that all parts are optimally laid out on
the material. The software automatically calculates the best placement of
even the most complex cut contours
and nests them together as tightly as
possible. This automated process significantly reduces the time required
for job preparation and setup, and
maximizes material yield while minimizing cut waste. Besides the tremen-

dous labour savings, the automated
nesting function has also helped the
company achieve an impressive 20% or
more in material savings.
The fact that the team was already familiar with the Zünd PN and software
was a plus, but even so, the layout of
the G3's Zünd Cut Centre (ZCC) user
interface is very intuitive and makes
the system extremely easy to use. Consequently, the time it took for the operator to learn the new system was very
short. Because of its open architecture,
the G3 was also exceedingly easy to
integrate in the existing production
workflow.

Performance at its best
The new cutting system is equipped to
handle the rigorous demands of processing carbon fibre. The electronics
box, for instance, is specially protected
against contamination from electrically-conductive carbon fibres and the
damage they can cause. Some of the
tooling, too, was developed specifically for use in applications involving
composites, with positive air pressure
protecting the mechanical parts of the
high-performance tools from abrasive
dust particles.

The majority of parts
that go into a Pagani are
painstakingly crafted by
hand

Feature Automation

The Zünd electric oscillating tool
(EOT) is the perfect tool for this application. The EOT is extremely versatile, and the team actually use it for
cutting all types of carbon fibre materials quickly and efficiently. Pagani
also has a need for processing honeycomb materials. These are cut on the

Pagani has been relying on equipment from Swiss cutting-system manufacturer Zünd for more than15 years. A few months back, the company installed a
new Zünd G3 L-2500
