Smart brake discs: visual inspection instead of sensors

The focus is increasingly on coated grey cast iron or even ceramic brake discs. PM10 particulate emissions are up to 90% lower with carbon-ceramic brake discs than with grey cast iron, and wear and particle toxicity are also very low. In addition, coated brake discs can be laser-marked at different depths, providing a practical solution for compliance with the Euro 7 standard.

Visible, easy to maintain and cost-efficient

Trotec offers an integration laser for this application, producing markings with a depth of 90 µm ± 5 µm. Engraving takes less than six seconds, with a roughness below 10 µm providing a clear visual inspection and a simple way of checking the condition.

There is no need for time-consuming dismantling or sensor technology.

Application example:

A sports car manufacturer uses Trotec lasers to mark wear indicators on carbon-ceramic discs. The marking remains legible even after exposure to high temperatures, enabling simple visual inspection during maintenance. Customer quote: "The laser-engraved wear marking is a real game changer for us — it meets the standard while saving costs and reducing complexity."
