KOMEG: Noticeably More Experience.
Measurably Better Results.
Substantiated experience, reliable expertise and future-oriented concepts: For
more than three decades KOMEG has been among the international innovation
generators of sophisticated industrial measuring technique, setting important
technological milestones and providing groundbreaking customer-specific
KOMEG implemented for example the first in-line measuring computers for SPC
application worldwide as well as the first modulare clamping system for repro-
ducible manufacturing - proficiency and knowledge that are being broadened
and deepened consistently ever since.
Today KOMEG develops, produces and distributes important components and
systems for manufacturing and coordinate measuring technique:
• Probe components for all CMM brands
• Special styli and configurations
• Modular indexable clamping systems for tactile and vision
measuring technique
• Handling technique and loading systems
• Air-conditioned cabinets and air-conditioning technique
• Special solutions
• Measuring and quality data systems
55 employees are permanently concerned with the progress of
measuring technique on the 3500 m² large state-of-the-art
KOMEG Development and Production Center in Völklingen,
Saarland - and with the satisfaction of customers from manifold
industrial production branches – from machine and automotive
engineering as well as electrical and plastics engineering, pharma
industry and medical technology.
KOMEG’s strong points are its extraordinary creativity, commit-
ment and local presence - based on a very strong foundation: as a
member of Mitutoyo Group, the most versatile supplier of length
measuring technique world-wide and internationally leading full-
range supplier in this branch of industry, offering more than 5000
KOMEG’s expertise and MITUTOYO’s strength complement one
another to enable complex and consistent system solutions - to the
benefit and advantage of highly demanding users of measuring
With noticeably more experience. For measurably better results.
KOMEG: We have an idea…
Styli made by KOMEG:
Tip top quality.
Steel, aluminum or ceramic? Ruby, zirconium oxide or silicon nitride? Which
stylus is best suited under which conditions for use in your coordinate mea-
suring equipment, for your specific measuring task?
With nearly 30 years of experience in manufacturing styli and based on its
cutting-edge materials development, KOMEG can offer competent advice.
Our experts know with absolute certainty which material in which combina-
tion will enable you to achieve your goals reliably and accurately.
At KOMEG the choice is always yours – but the result is the same every
time: the best.
Our expertise and use of the highest-quality materials guarantee products
offering unparalleled excellence:
The materials we use for spherical probes
As the hardest of all probe element materials, ruby is the perfect
all-rounder when it comes to manufacturing balls. Spherical probes
made of ruby have been used as tried and tested equipment for
most standard applications for decades.
The low specific density of ruby enables the mass of the stylus tip to
be kept as small as possible – this effectively allows the elimination
of false triggers caused by mass inertia when the CMM moves or
Zirconium oxide
Because of the specific surface properties of balls made of zirconium
oxide - a ceramic compound – they are acknowledged specialists for
aggressive scanning of abrasive surfaces, such as workpieces made
of cast iron. Zirconium oxide has virtually the same hardness and
wear-resistant properties as ruby.
Silicon nitride
Silicon nitride is extremely hard and superbly wear-resistant, with
the least surface roughness of all ball materials. Specific advantage:
Silicon nitride is not attracted by aluminum and therefore coats the
surfaces of workpieces made of aluminum to a much lesser extent
than other ball materials.
The materials we use for bases and stylus stems
The primary material of choice for high-strength precision styli
that enable minutely accurate measuring tasks. Its superb material
strength makes steel an excellent choice of material for manufactu-
ring styli or reference probe elements.
Carbon fiber tube
Special advanced aerospace technology has produced this type of
carbon fiber, whose thermal expansion coefficient range is virtually
undetectable at temperatures of between 15 and 40 degrees centi-
grade. KOMEG makes ideal use of carbon fiber tube for manufactu-
ring styli of outstanding quality, sophisticated styli configurations and
probe extensions.
Lightweight and stable, and therefore frequently used for probe
extensions. Stylus stems made of aluminum or with aluminum
extension perform best in measuring labs with stable temperatures
and accordingly, the lowest possible temperature gradients.
Carbon fiber
The highest-quality material with an expansion coefficient of virtually
zero at ambient temperatures of up to 45 degrees centigrade.
Carbon fiber is also very lightweight and extremely strong, making it
particularly suitable for the manufacture of long styli.
Tungsten carbide
Bend-resistant stylus stems made of tungsten carbide are ideal for
virtually all standard applications in the measuring lab with its stable
ambient temperatures. A durable material that has proved its worth.
Titanium is remarkably strong yet with a relatively low density. Probe
components made of titanium offer the outstanding characteristics
of being extremely rigid and stable, yet surprisingly light. KOMEG
uses the material primarily for bases, connecting pieces and extensi-
ons of measuring styli.
Very lightweight and extremely strong. The ideal material, espe-
cially for long stems. Their low tendency to expand in warmer
temperatures makes ceramic styli also suitable for use in production
Styli made by KOMEG: Confidence that comes
from knowing you have made the right choice.
