Advantages of CNC Laser Hardening Machine

Lower chance of distortion

In typical hardening processes, the combination of heating the entire workpiece or a larger part of the workpiece and subsequent liquid quenching operations leads in a significant risk of deformation and cracking in the treated workpieces.

Improved compatibility with tiny components

Diode lasers allow for fine control of surface temperature and laser beam placement. This capability enables the process engineer to predictably regulate the heat input, which is crucial for repeatable production hardening procedures.

Reduced processing costs

In comparison to other case hardening procedures like as flame and induction hardening, laser hardening is a non-contact process capable of producing only the appropriate case depth.

Greater part geometries suitability

Flame hardening and induction hardening, for example, have trouble treating workpieces with complicated geometries. Regardless of shape, the noncontact laser hardening technology may selectively case harden workpiece surfaces.

Application of CNC Laser Hardening Machine

Combination pliers, long nose pliers, Diagonal pliers, Pincer, Bot cutter Knife, Garden cutting tools, sawblade etc.
