The laser ablation fine balancing system measures rotational imbalance and precisely removes material at targeted locations to achieve optimal balance. A measurement unit calculates imbalance magnitude and angular position, transmitting this data to the laser control system. Laser pulses then ablate microscopic amounts of material either dynamically during rotation or statically after measurement. This non-contact process maintains part integrity, avoids mechanical stress, and allows correction in one or two planes with high productivity. Typical workpieces include impellers, airdriven turbines, and small motor rotors made from metals or plastics, with ablation tuned to material characteristics for clean, burr-free results.

High-Precision Laser Ablation

The system removes microscopic amounts of material with exact laser positioning, enabling correction of even the smallest imbalance without mechanical contact.

Integrated Imbalance Measurement and Control

A measurement unit determines imbalance magnitude and angular position relative to a reference, allowing automated calculation and corrective ablation.

Dynamic and Static Balancing

Material removal can occur while the workpiece rotates, saving time by eliminating repeated acceleration cycles, or statically for specific process requirements.

Two-Plane Correction Capability

The laser switches between planes rapidly to balance components with complex mass distributions, improving balance precision.

Non-Contact and Wear-Free Processing

Laser ablation avoids tool wear and generates minimal mechanical stress, enhancing system longevity and part integrity.

Multi-Material Support

By selecting appropriate laser sources—such as CO₂ for plastics or high-peak-power lasers for metals—the system handles a broad range of materials without burrs or residues.

Cost-Effective Design Freedom

Precise ablation removes the need for balancing weights or complex machining features, reducing part cost and enabling innovative geometries.

Automation and Productivity

The balancing process can be integrated into automated lines with loading/unloading systems, enabling unattended high-volume processing and reduced cycle times.
