Tolerances down to ± 0.01 mm have to be
held and while this is commonplace when
machining metals, for carbon bre parts it is
challenging. GTR’s success in this area is
down to its long experience working with
composites, coupled with the rigidity of the
Hermles that avoids generation of harmonics
when trimming thin carbon bre sections.
Thin-wall structures are needed to minimise
weight in race cars, supercars and aircraft,
but edges must be nearly perfect to avoid
stress fractures, so vibration when using the
mainly PCD (polycrystalline diamond) cutters
cannot be tolerated.
It was the performance of the Hermle
already at the rm taken over that won the
new investment. Says Kingdon-Butcher:
“The performance and reliability of this
machine played a part in our decision to
purchase two new models of the same make,
despite having used 5-axis machining centres
from other suppliers for many years. Hermle
machines have a good reputation in the
market and our machine shop manager,
Martin Sammut, was familiar with the brand.”
At Kadel Engineering, it is metrology
investment that was required. The company
is using a Baty Venture XT 3030 CNC vision
system to ensure the accurate manufacture
of precision components for Formula One
cars. Bowers Group (https://is.gd/vubegu)
supplied the system. Parts must always meet
tight tolerances, typically within 0.010 mm.
It was the challenge that a previous
component had presented that prompted the
investment – some key component features
could not be measured accurately and
con dently.
Paul Rollins, managing director at
Keighley, West Yorkshire-based Kadel
Engineering, says: “Components are needed
at short notice for the build of the F1 cars,
and are often required to be own out to a
race on the other side of the world. It is
imperative that parts conform to the correct
tolerances rst time, as there is usually no
time to remake or rework parts that do not
meet those tolerances. Parts are rigorously
checked by our customers and our quality
and performance closely monitored.
“The Baty Venture XT acts as another
inspector and an extra check, so it’s near
impossible for anything to slip through the net
unnoticed. It can be used as an optical

This Baty Venture XT bench-top CMM
machine is helping Kadel Engineering
measure more reliably
measuring machine and a CMM, so the
combination effectively gives us two
machines in one, which is just what we
needed for the parts we manufacture. We felt
that it would not only give our customers
more con dence in our ability, it also enables
us to take on more complex parts, now we
can measure them. It’s also very easy to use
and the software is very user friendly. There’s
the added advantage that its very small and
compact and doesn’t take up much room.”
Apart from measurement, the Baty unit is
also used as a visual inspection aid, because
it has a powerful zoom lens and good surface
illumination. Concludes Rollins: “We are really
happy with the service we received from
Bowers Group. The delivery was very quick
and ef ciently handled, and the training was
very thorough too.”
