INNOVATIONS 2
FOR THE AUTOMOTIVE INDUSTRY
Economical grinding
of hard-coated brakes
The automotive industry is currently
undergoing rapid change. With the
Euro 7 emissions standard by the EU,
which should apply from 2025 on,
a significant reduction of fine dust
pollution is driven forward.
At the same time, regulations for the permissible
brake abrasion and for tyres will come into effect,
which will drastically change the requirements for
vehicle manufacturers. For the first time, electric
cars are also directly affected. This leads inevitably
to a further development of the brake concepts
currently in use.
Thanks to the introduction of hard-coated brakes,
manufacturers will be able to reach an optimal
combination of first-class braking properties and
minimal abrasion, which will lead to a reduction in
fine dust pollution according to the new standards.
Due to these innovations, advanced production
technologies are needed to grind brake discs
economically and efficiently. With the GRAVIS
portfolio we support you in this change. In addition,
we offer unrivalled application technology support
in order to develop new grinding processes
and continuously optimise production together
with our partners.

The stock removal on coatings made from hard
materials is extremely difficult. Therefore, excellent
abrasives and high spindle capacities are essential
for the machining of brake discs.
The new Tyrolit GRAVIS product line offers tools for double side face
grinding of hard-coated brake discs with first-rate segments and cup
wheels. These specially developed products achieve an even stock
removal rate on both sides of the brake disc and offer you maximum
cutting ability, resulting in low grinding forces. With Tyrolit products,
you can achieve the best surface results in the shortest possible time
combined with incomparable durability.

processes and align the abrasives perfectly.
With GRAVIS, you are able to fully meet requirements
concerning the ground brake disc and the grinding
process, regardless of the machine concept. Our focus
lies on the continuous optimisation of our production
in order to manufacture excellent products, using
the latest manufacturing methods, and to equip our
customers with them. Additionally, our experts support
you in designing the right grinding procedure and
selecting the fitting grinding tool. In series production,
you can rely on a global partner who works with you to
continuously improve processes and results. Tyrolit is
your reliable and competent partner for grinding hardcoated
brake discs.

Coating processes
At the moment, the hard materials used, the coating
processes and the process parameters are constantly
changing, which has a major impact on the grindability
of brake discs. Tyrolit is in intensive dialogue
with machine manufacturers in order to incorporate
the rapid development of coating variants into our
grinding concepts. We offer our customers solutions
for all coating processes and hard materials in order
to offer the best products for future requirements.
