This document discusses the challenges and advantages of laser engraving on finished components. Some of the key challenges include 360 degree engraving on curved surfaces, precise positioning of components, and ensuring surfaces are not degraded. The system provides accurate angular positioning of engraving within 0.5 degrees and symmetry within 0.035 mm. It handles components only once to avoid degradation and has a sorting station that can hold 600 components across multiple batches. Repeatable, precise engraving is achieved through a galvanometric laser head and accurate positioning of the component.
