Auto-Zoom Variable Spot Laser Hardening Head

The Variable Beam Laser Hardening Head features an automatic zoom system that continuously adjusts the beam size to match the geometry of the workpiece. It adapts to curved, tapered, and irregular surfaces, making it ideal for complex-shaped components, large conical surfaces, and selective hardening areas. Hardening depths of up to 2 mm can be achieved, with full-surface or selective-area options. Distortion is tightly controlled within 0.03 mm, and no post-processing or dimensional changes are required. This head provides a smart, high-precision laser hardening solution for components with challenging geometries.

FAQ

Q1: How does the automatic zoom system work, and what types of workpiece geometries can it handle?

A1: The automatic zoom system continuously adjusts the beam size in real time to match the geometry of the workpiece. This allows the head to adapt seamlessly to curved, tapered, and irregular surfaces — making it ideal for complex-shaped components, large conical surfaces,and selective hardening areas where conventional fixed-beam heads would require multiple passes or manual repositioning.

Q2: What level of distortion can I expect with this variable beam hardening head, and is post-processing required?

A2: This head delivers distortion tightly controlled within 0.03 mm — significantly better than conventional hardening methods. No post-processing or dimensional adjustments are required after hardening, as the process preserves the original component dimensions and surface finish. This makes it ideal for high-precision components such as crankshafts, drive shafts, hydraulic plungers, and tapered rollers where tight tolerances are critical.
