Starting in 2026, original equipment manufacturers (OEMs) must demonstrate that vehicles meet strict Euro 7 standards. This regulation extends beyond emissions to include specific performance metrics in braking tests. Laser-based wear marking offers a robust, standard-compliant solution for these new requirements.
Highlights
- Euro 7 compliance: New mandates for braking system performance begin in 2026.
- Precision marking: Picosecond lasers achieve 100 µm depth with ±5 µm tolerance.
- Cold ablation: Material is vaporized without causing thermal stress to the component.
- Visual inspection: Allows for wear assessment without sensors or disc removal.
Picosecond Laser Technology
Trotec Laser provides a 100 W picosecond laser designed specifically for brake disc applications. This system allows for the precise creation of wear markings. The technology ensures consistent results suitable for industrial production environments.
The system delivers high-precision specifications:
- Marking depth: 100 µm
- Tolerance: ±5 µm
- Power output: 100 W
Material Integrity and Engraving
The engraving process utilizes cold ablation. This method vaporizes the material effectively without subjecting the brake disc to thermal stress. Avoiding heat inputs is critical for maintaining the structural integrity of safety-critical components.
The laser utilizes extremely short pulses to achieve this result. This high level of precision makes the integration laser suitable for sensitive materials. It ensures the braking surface remains unaltered outside the marked area.
Meeting Euro 7 Requirements
To comply with the Euro 7 standard, vehicles require a testable wear indicator. This indicator must function without the use of electronic sensors. It must also allow for inspection without removing the brake discs.
The laser-based solution meets these specific regulatory requirements. It significantly reduces technical complexity and manufacturing costs compared to sensor-based alternatives. Workshops and end users can visually assess the condition of the brake disc at any time.
