Laser Hardening Equipment for Outer Circle & Inner Hole - China Suppliers & Factory for Precision Engineering

Equipped with a synchronized rotary-tilting mechanism, the system seamlessly hardens both external cylindrical surfaces and internal bores (from 10mm to 500mm diameters) in a single setup. The integrated dynamic beam shaping ensures consistent energy distribution across curved geometries.

Advanced infrared sensors monitor surface temperature during quenching, automatically adjusting laser power (500-3000W range) and scan speed (0.1-5m/min) to prevent overheating or incomplete phase transformation.

Quick-change clamps and adjustable mandrels accommodate diverse workpiece sizes (lengths up to 3m), reducing setup time by 50% for mixed-batch production.

Laser hardening eliminates mechanical stress, achieving surface hardness of 55-62 HRC with a controlled case depth of 0.2-2.0mm, ideal for materials like alloy steels, cast iron, and stainless steels.

Harden crankshaft journals, camshaft lobes, and transmission gear bores to withstand high cyclic loads and friction.

Strengthen piston rods, cylinder liners, and valve sleeves for extended service life in high-pressure environments.

Enhance wear resistance of landing gear axles and turbine shaft bores exposed to extreme operational stresses.

Protect drill pipe threads and pump housings from abrasive wear and corrosion in harsh drilling conditions.

Direct laser energy utilization reduces power consumption by 35% compared to induction hardening methods.

Eliminates quenching oils or polymers, aligning with eco-friendly manufacturing standards.

IoT-enabled controllers log process parameters (hardness depth, scan patterns) for traceability and quality assurance.
