What is a Laser Marking Machine?

A laser marking machine uses a non-contact processing method with lasers to create permanent marks on material surfaces. It employs a beam generated by a laser, which is focused onto the material surface through a focusing system. The instantaneous high temperature or ionization causes localized physical or chemical changes in the material, resulting in a texture or color that differs from the rest of the surface. Whether it's metal, plastic, wood, or stone, it can accurately mark various texts, symbols, or patterns with micron-level precision.

The non-contact processing characteristic of lasers prevents material deformation, making it particularly adept at fine marking on small components and complex curved surfaces. Compared to traditional printing or etching techniques, laser marking offers the advantages of no consumables, no pollution, high efficiency, and permanent marks. It is widely used in industries such as plastic buttons, digital product components, electronic components, electrical appliances, jewelry, precision machinery, eyewear and watches, hardware accessories, automotive and motorcycle parts, sanitary ware, communication products, medical devices, integrated circuits, building materials, and personalized marking. It is especially suitable for product identification requiring high precision, speed, and depth, making it an indispensable marking technology in modern intelligent manufacturing.

Components of a Laser Marking Machine

Whether it is a fiber laser marking machine, a CO2 laser marking machine, or a UV laser marking machine, the main components are all composed of a laser generator, a galvanometer scanning system, a field lens, a worktable, a control system, and a cooling system. Each core component and auxiliary system works together to achieve high-precision and high-efficiency marking functions.

Laser Generator

The heart of the laser marking machine, primarily responsible for generating the laser beam, is divided into fiber laser generators, CO2 laser generators, and UV laser generators. Different laser generators are suitable for different materials and should be selected based on material and process requirements. Fiber laser generators are mainly used for metal materials and some non-transparent plastic materials, CO2 lasers are mainly used for various non-metal materials, and UV lasers can perform fine processing on almost any material.

Galvanometer Scanning System

The galvanometer is the core component of the laser marking machine, used to control the scanning path of the laser beam. It adjusts the deflection of the mirrors through motors, changing the movement trajectory of the laser on the workpiece surface to form the desired patterns or text. The galvanometer can not only be used for laser marking but also for laser cutting, 3D engraving, and more.

Field Lens

The field lens is the important optical component of the laser marking machine, ensuring the formation of uniform and consistent focused spots across the entire marking area. It is responsible for focusing the deflected laser beam onto the workpiece surface. The scanning range of the field lens determines the working area of the laser marking. A smaller scanning range of the field lens can increase laser energy density, deepening the marking depth. A larger field lens can expand the laser marking area but will reduce the density of part of the laser energy. A laser marking machine can be equipped with multiple field lenses, which can be freely replaced according to different processing scenarios.

Control System

The control system of the laser marking machine is the brain of the entire machine, consisting of hardware and software components, used to coordinate the collaborative work of the machine's various parts. The hardware part uses control cards to connect and control hardware such as the laser generator and galvanometer system. The software part can perform file import, graphic editing, processing parameter settings, marking task management, and more.

Worktable

The worktable of the laser marking machine uses a multi-hole fixing plate made of aluminum alloy, which can be used with aluminum alloy side rails to facilitate the fixation of workpieces. The aluminum alloy worktable combines stability and lightweight properties, is not easily deformed, and dissipates heat quickly.

Cooling System

It is used to cool down the laser generator to prevent excessive temperatures. There are two cooling methods: air cooling and circulating water cooling.

Working Principle of Laser Marking Machines

Fiber Laser Marking Machine

The laser uses ytterbium-doped double-clad glass fiber as the laser gain medium. Under the excitation of the laser pump source, a stable and high-density laser beam is formed inside the fiber laser. The laser beam is then exported through the fiber and enters the galvanometer scanning system, where its deflection angle is controlled by the digital control system to precisely adjust the path of the laser beam. Subsequently, it is focused into an extremely small spot through the field lens, enabling rapid automatic scanning and marking of complex patterns or text.

CO2 Laser Marking Machine

This machine uses a sealed laser filled with a mixture of CO2, nitrogen, and helium gases. High-voltage discharge inside the laser excites gas molecules to transition to a higher energy level. When the gas molecules return to a lower energy level, they release infrared laser light with a wavelength of 10.6 micrometers. The laser is amplified through multiple reflections within the laser resonator cavity, forming a high-energy-density laser beam. The control system then directs the galvanometer to oscillate rapidly, and the laser beam is reflected by the high-speed galvanometer system and focused by the field lens, achieving precise scanning and marking on a plane.

UV Laser Marking Machine

The UV laser marking machine uses a solid-state laser as the laser source. Through third-order intracavity frequency doubling technology, the infrared laser is converted into ultraviolet laser light with a central wavelength of 355 nm. The generated ultraviolet laser is precisely controlled in its path by the galvanometer system, and the field lens adjusts the focus position and movement trajectory of the laser beam, enabling fast and accurate marking of workpieces.

Unlike the thermal processing of fiber lasers and CO2 lasers, UV lasers use photochemical ablation for marking. High-energy ultraviolet photons can directly break the chemical bonds on the material surface or surrounding medium, creating permanent marks. The process generates almost no heat, making it a cold laser. It does not produce any thermal effects on the surface or nearby areas of the processed product, avoiding issues such as thermal deformation and discoloration. Additionally, the laser beam diameter of UV lasers is finer than that of CO2 and fiber lasers, with better beam quality, allowing for ultra-fine processing.
