UV8220-3D-600-GST UV 3D Dynamic Focus Galvo Scanner (355 nm, 600×600×150 mm Working Volume, Water-Cooled, XY2-100)
Presentation of the equipment's characteristics
The UV8220-3D-600-GST UV Dynamic Focusing Scanning System is a large-area 3D dynamic focus galvo scanner built for 355 nm UV laser marking, cutting, drilling, and precision micromachining. Designed for wide-format processing and 3D applications, it supports high-speed scanning while dynamically maintaining focus across height variations—ideal for consistent results on complex surfaces and deep processing jobs.
This system is suitable for large-area UV laser processing, 3D marking/engraving, laser micro-processing, and rapid laser-based manufacturing workflows. It can process a wide range of materials including metals, plastics, glass, ceramic tiles, marble, jade, and crystal.
MM3D software workflow (fast setup, easy operation)
Supports multiple file formats and imports vector graphics, 3D models, bitmaps, text, and barcodes—simple to learn and efficient for production.Extra-large marking field with 3D height capability
Supports up to 600 × 600 mm marking area, with a maximum height difference (Z depth) up to 150 mm for large-format 3D processing.Water-cooled structure for stable long-duration operation
Water cooling effectively controls galvo operating temperature, improving stability and repeatability in continuous industrial use.EMC-optimized design for strong noise immunity
High signal-to-noise performance and strong anti-interference capability help ensure reliable operation in complex factory environments.Precision Z-axis dynamic focusing for consistent spot quality
Precisely controls focal position. During 3D depth marking, the system automatically adjusts the Z-axis range to maintain an optimized spot and consistent marking results.Optimized third-axis (focus axis) load design
Precision optical load design for the focus axis, with high assembly accuracy, low static friction, and low zero drift—supporting excellent dynamic performance.
