3D dynamic focus laser marking machine adopt imported core components, with high-speed, high precision 3D galvo, and with our 3D specified software and control system, it can engrave on any curved workpieces in a fine process, there is no off-focus problem. It can also adjust focus length any time for deep engraving, which makes process efficiency and marking quality much better than traditional 2D fiber laser marking machine. we make real 3D marking function come true, leading a new era of laser processing.
