The UV laser engraving machine is developed using a 355nm UV laser source. Utilizing third-order cavity intra-cavity frequency doubling technology, compared to infrared lasers, the 355nm UV light has an extremely small focused spot, which significantly reduces material mechanical deformation and minimizes thermal processing effects. Therefore, it is mainly used for ultra-fine marking and engraving, particularly suitable for applications such as food and pharmaceutical packaging material marking, creating micro-holes, high-speed division of glass materials, and complex graphic cutting on silicon wafer boules.

Control System

The control system governs the operation of the entire machine, including power and control to the optical system components, cooling system, and control and indication of the alarm system.

Computer Control System

Computer control system includes computers, digital galvanometer cards, and drives optical system components to act according to the parameters set by the marking control software, emitting pulse lasers to engrave the desired marking content on the surface of the processed item. The control system features a full Chinese interface, compatible with file outputs from various software such as AUTOCAD, CORELDRAW, and PHOTOSHOP. It supports marking with barcodes, QR codes, graphic texts, and more. It is compatible with file formats like PLT, PCX, DXF, BMP, AI, and uses SHX, TTF fonts directly, enabling automatic encoding and printing of serial numbers, batch numbers, and dates.

3. Optical System
