Frequently Asked Questions

What are the advantages of laser beam machining (LBM) for precision components?

Laser beam machining offers contactless material removal, enabling extremely fine features without mechanical stress on delicate parts. It allows high precision on hard or brittle materials, minimal heat-affected zones with proper parameters, and the ability to machine complex geometries. For laser assembly components specifically, LBM can complement traditional CNC methods for features that require micron-level accuracy.
