How To Explain A Laser Marking Machine

Fiber laser marking machine is a laser that uses rare-earth element-doped glass fiber as the gain medium. Fiber laser marking machine has become a hot spot in laser physics research in recent years, and it is unanimously considered to be a new generation of products that may completely replace solid-state lasers. Fiber lasers can be developed on the basis of fiber amplifiers: under the action of pump light, it is easy to form high power density in the fiber, resulting in the "number inversion" of the laser energy level of the laser working material. When a positive feedback loop is properly added ( form a resonant cavity) to form a laser oscillation output. The fiber laser marking machine uses a laser beam to mark permanent marks on the surface of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, or to "engrave" traces through the physical changes of the surface material caused by light energy, or to burn off part of the material through light energy to reveal the desired etching pattern. , text, barcodes and other graphics.

applied research
The so-called fiber laser marking machine means that the marking machine uses a fiber laser. The fiber laser has the characteristics of small size (no water cooling device, air cooling), good beam quality (fundamental mode), maintenance-free, etc.
It is mainly composed of three parts: laser, galvanometer and marking card. The laser marking machine using fiber laser has good beam quality, its output center is 1064nm, and the life of the whole machine is about 100,000 hours. Compared with other types of laser marking Compared with other types of laser marking machines, the conversion efficiency of 2%-10% has a great advantage, and it has outstanding performance in energy saving and environmental protection.
Fiber laser marking machine Features:
1. It can process a variety of metal and non-metal materials. In particular, it is more advantageous to mark high hardness, high melting point and brittle materials.
2. It belongs to non-contact processing, does not damage the product, has no tool wear, and has good marking quality.
3. The laser beam is thin, the processing material consumption is small, and the processing heat affected zone is small.
4. High processing efficiency, computer control, easy to realize automation.
Application field
Widely used in integrated circuit chips, computer accessories, industrial bearings, clocks, electronic and communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds, wires and cables, food packaging, jewelry, tobacco and military affairs, etc. Field graphics and text marking, as well as high-volume production line jobs.

What are the performance of laser marking machines?

Laser marking machines have a variety of performance characteristics, mainly including the following aspects:

1. Non-contact processing: The laser marking machine adopts non-contact processing, which can mark without touching the workpiece, avoiding mechanical pressure and damage to the workpiece.

2. Wide range of applicable materials: Laser marking machines can be applied to a variety of different materials, including metals, non-metals, plastics, glass and other materials.

3. High marking accuracy: The laser marking machine uses high-precision laser beam processing, which can achieve high-precision marking and engraving, with clear and beautiful effects.

4. Fast speed: The laser marking machine has high-speed marking capabilities and can quickly complete a large number of marking tasks and improve production efficiency.

5. Strong permanence: The marks marked by the laser marking machine are permanent and will not fade due to environmental factors and can be maintained for a long time.

6. Environmental protection: The laser marking machine adopts a non-traditional marking method and does not require the use of chemicals or inks, reducing environmental pollution.

7. Strong customizability: The laser marking machine can be customized according to customer needs to achieve different marking effects and patterns to meet the personalized needs of customers.

8. Low maintenance costs: The laser marking machine has a long service life and relatively low maintenance costs. Long-term use can reduce production costs.

In general, laser marking machines have a variety of excellent performance characteristics, can meet various marking needs, and have been widely used in industrial production and processing fields.

So how long is the service life of the laser marking machine?

The service life of a laser marking machine depends on many factors, including brand, model, quality, frequency of use, and maintenance. Typically, if the equipment is of reliable quality and properly used and maintained, the service life of a laser marking machine can reach tens of thousands of hours or even longer.

The core component of a laser marking machine is the laser, and its life span depends on the type and usage. For example, fiber lasers usually have a long life, which can reach about 100,000 hours. The lifespan of laser marking machines such as CO2 lasers, UV lasers and green lasers is relatively short, ranging from a few thousand to 10,000 hours. In addition, other parts of the laser marking machine also have a service life, such as lenses, lenses, scanning heads, etc., and need to be replaced or maintained regularly.

The use environment also has an impact on the life of the laser marking machine. Harsh environments can cause wear and damage to components, shortening service life. Therefore, maintaining a suitable working environment and frequency of use, and performing regular maintenance are important measures to extend the life of the laser marking machine.

In general, the service life of a laser marking machine varies depending on the specific situation, and a fixed number cannot be given. Choosing equipment from reliable brands and guaranteed quality, and operating in accordance with the manufacturer's usage and maintenance recommendations, can maximize the service life of the laser marking machine.
