Induction hardening of rails is a heat treatment process that increases the hardness and wear resistance of linear guide rails. The repeatability and controllability of induction hardening make the heat treatment process of the entire rail more automated. We generally heat and cool the rails with a dedicated rail induction hardening machine.
The linear guide rail is an important part of the machine tool, and it needs to have high hardness and wear resistance. The service life and wear resistance of the guide rail after hardening will be greatly improved. Generally, induction hardening of guide rails is followed by an induction tempering process, which can significantly improve the hardness of steel guide rails, reduce brittleness, and improve their toughness.
Technical indicators of guide rail hardening:
- Quenching depth: 1.5-3 mm.
- Hardness: 45 HRC-52 HRC.
- Guide rail quenching deformation: <0.06 mm.
