What Is A Laser Marking Machine? - Definition

Laser marking machine is a type of laser system with CNC (Computer Numerical Control) which adopts fiber, CO2 or UV laser beam to leave permanent marks of letters, numbers, signs, logos, patterns, pictures, photos on an 2D/3D surface such as metals (stainless steel, carbon steel, galvanized steel, alloy, copper, brass, aluminum, gold, silver, iron, titanium), wood, leather, fabric, plastic, glass which also includes color change due to chemical or molecular alteration, charring, foaming, melting, ablation, etc. This is different from ordinary inkjet printing and CO2 laser marker. Laser marker has advantages of high speed, high quality, high precision, pollution-free, safety, easy operation, free maintenance and low cost. Laser marking machines are also known as laser markers, laser mark machines, laser marker machines, laser marking systems, laser etching machines, laser stippling machines, laser labeling machines, laser printing machines and laser marking tools.

How Does A Laser Marking System Work? - Working Principle

Laser marking systems adopt laser beam to mark label that has been made by graphic utilities. There are both 2D mark for flat surfaces, and 3D mark for curved surfaces.

2D Laser Marking System

The mirror galvanometers are used to scan laser beam and mark on 2D surface. The f˜ lens is used to concentrate the light on the 2D surface.

3D Laser Marking System

The mirror galvanometers are used to scan laser beam and mark on 3D surface. They will move the focus lens (instead of f˜ lens) back and start adjusting the laser beam not only on X axis and Y axis, but also on Z axis.

Laser Marking Process

The system has six different marking processes include annealing engraving, marking, staining, foaming, removing and carbonizing, which is widely used in industrial manufacturing applications, school education, small businesses, home business, small shop and home shop.

What Are Laser Marking Machines Used For? - Applications

The best laser marking machines are distinguished by the laser oscillator. We have fiber laser oscillator generating a 1.06μm laser beam, a UV laser oscillator generating a 0.355μm laser beam, a CO2 laser oscillator generating a 10.6μm laser beam. UV laser converts a fundamental laser to one-third wavelength by a non-linear optical crystal. Fiber lasers are known for generating power effciently, thy are compact due to the oscillation principle. Fiber laser is more suitable for processing metals than UV laser and CO2 laser. UV lasers are effected by the laser wavelength conversions, they can make detailed processing with a low thermal effect for the materials that have a high absorption rate for these wavelengths, however, the operating cost may be high. UV laser markers are very good for plastic. CO2 lasers are more easily absorbed by clear materials because they have a longer wavelength than fiber lasers and UV lasers, this makes them good for marking glass or other clear materials. CO2 lasers are very good for PVC, paper, rubber, glass and wood.

What Are The Advantages And Benefits Of Laser Marking?

Laser marking is one of the fastest stipping solutions available in the market. This results in high productivity and cost benefits during manufacture. Depending on the material structure and size, different laser machines (e. g. galvo lasers) or laser sources (e. g. fiber lasers) can be used to further increase the speed. It's permanent and at the same time resistant to abrasion, heat and acids. Depending on the parameter settings, certain materials can also be marked without damaging the surface. Thanks to the high precision of marking, even very delicate graphics, 1-point fonts and very small geometries will turn out clearly legible. At the same time, stipping with the laser ensures constant high-quality results.

As a modern precision engraving method, laser marking technology has unparalleled advantages compared with traditional engraving methods such as corrosion, EDM, mechanical scribing, and printing:

1. The laser is used as a engraving method, and there is no processing force between the workpiece and the workpiece. It has the advantages of no contact, no cutting force, and small thermal influence, which ensures the original accuracy of the workpiece. At the same time, it has wide adaptability to materials, can make very fine marks on the surface of a variety of materials and has very good durability;

2. The space control and time control of the laser are very good, and the material, shape, size and processing environment of the processing object are very free. It is especially suitable for automatic engraving and special surface engraving. And the engraving method is flexible, which can not only meet the needs of laboratory-style single-item design, but also meet the requirements of industrialized mass production;

3. Laser marked lines can reach the order of millimeters to micrometers. It is very difficult to imitate and change the marks made by laser marking technology, which is extremely important for product anti-counterfeiting;

4. The combination of laser marking system and CNC control technology can form efficient automatic engraving equipment, which can print various characters, symbols and patterns. It is easy to use software to design marking patterns, change marking content, and adapt to the high-efficiency and fast-paced requirements of modern production;

5. It has no pollution source and is a clean and pollution-free high environmental protection processing technology;

Laser marking technology has been widely used in all walks of life, opening up broad prospects for high-quality, high-efficiency, pollution-free and low-cost modern manufacturing and production. With the continuous expansion of modern laser marking applications, the requirements for miniaturization, high efficiency and integration of laser manufacturing systems are also higher.

Fault 4: The reason for not emitting light.

Solution:

1. The light path screws of the whole machine are loose, and the screws need to be tightened.

2. Whether there is too much dust in the gun body to prevent the gun endoscope from being injured. If found, the gun endoscope must be replaced.

3. When the chiller is turned on for a long time without turning on the laser power and lighting, it will cause freezing and no light. You need to turn off the power system of the whole machine for 1 hour and then restart it.

4. The lamp tube must be replaced if the lamp is aging or the laser power drops.

5. After working for a long time, the laser power drops, open the bottom cover of the gun body, you need to adjust it in the gun endoscope.

Solution:

1. It must be checked whether the graphics during processing are complicated.

2. Do not connect the online computer to the Internet cable, it is a separate control laser system.

3. Running slowly, please don't be too impatient at this time to avoid crashing.

4. Please pay attention to prevent viruses to prevent system errors.

Fault 6: The XY axis of the worktable is not punctual.

Solution:

1. Are the screws of the slide rail of the worktable loose?

2. The glass on the workbench is determined according to the customer's requirements, and the iron plate or plexiglass plate can be replaced, and the balance under the glass can be adjusted.

3. Electronic rulers can be installed on the right and upper and lower corners of the workbench, which can be installed to facilitate the needs of customers.

4. The screw holes on the workbench can be easily used by customers for positioning, which is negated by the product.

Fault 7: Jumping during operation, and the position is roughly fixed.

Solution:
