Laser hardening

Laser hardening

The most innovative technology of hardening

Efficiency plays an important role. With the new laser technology, we are increasing this immensely. Here, almost no post-processing is necessary, the workpieces are hardened low distortion or distortion-free and it remains the basic property of the material.

The special feature of the process is that it is hardened exactly where it is needed. With the laser, the surface layer areas are hardened locally. Concentrated heat accumulation via the laser guarantees minimal distortion and hard machining shall not be required. To be able to harden even complex geometries state-of-the-art 3D robotic technology and control systems are used. Compared to conventional surface hardening methods, the laser technology can be used to focus the area to be hardened and to precisely track it via the optical control systems.
