Abstrakt EN: Hardening of contact surfaces of milling head is centerpiece of this study. The most important point is to maintain defined processed part geometry. This precise processing was performed using the scanning laser hardening method. The scanning method uses a small laser spot in combination with a scanning head. The method is based on a very fast laser beam sweeping perpendicularly to the main laser treatment trajectory, allows better control of energy distribution and optimization of treating pattern. Disk laser with maximum power of 5.3 kW was used for heat treatment. Surface hardness and depth of hardened layer were evaluated. 3D profiles of hardened parts were measured on 3D scanner Alicona before and after laser processing. Geometrical deformations were assessed using the method of differential analysis.
