Laser hardening in video

Laser hardening of a drive gear

Laser hardening of a drive gear with a diameter of 510 mm, 83 teeth and made of 42CrMo4 material. Here, the tooth geometry is specifically hardened to 56 HRC.

Why laser hardening:

• Precise adjustment: Thanks to our zoom optics, the laser track width can be perfectly adjusted to the flank heights of a tooth.
• Efficiency & environmental friendliness: With a laser track speed of 4 mm per second, we achieve a high surface hardness while the material core remains tough.
• Low distortion & energy-saving: No quenching media required, minimal distortion and significant time savings.
