Fiber Laser Marking Machine

What is A Fiber Laser Marking Machine?
Fiber laser marking machine, also called fiber laser marker machine, is a kind of CNC laser engraving equipment which takes fiber laser to mark on the surfaces of a variety of metal materials. Fiber laser marking machine is characterized of high precision, fast working speed, excellent performance, thus is widely used in electronic components, integrated circuits (IC), electrical appliances, mobile communications, hardware products, tool accessories, precision equipment, etc.

How Does A Fiber Laser Marking Machine Work?

Fiber laser marking machine is an automatic laser marking machine composed of fiber laser generator, laser power supply, galvanometer scanning system, field lens scanning system, beam combiner, computer control system, focusing system, laser software, machine frame, red light indicator, laser marking control card, power filter, and more laser parts & accessories. The laser generator provides a laser source, which is expanded by the fiber and imported to the XY mirror of the scanning galvanometer. The combined control of marking software, scanning galvanometer and laser generator can mark permanent text or patterns on the workpiece. The working principle of the fiber laser engraving machine is that a laser beam with extremely high energy density is irradiated to the surface of the product to be marked under the control of a computer, and the desired pattern or text is ablated. Fiber laser generators have become a hot topic in laser physics research in recent years. It is unanimously considered as a new generation product that may completely replace solid-state laser generators. Fiber laser generator refers to a laser generator that uses rare-earth-doped glass fiber as the gain medium. The laser generator can be developed on the basis of a fiber amplifier. Under the action of the pump light, high power density is easily formed in the fiber, causing the laser energy level of the laser working substance to “populate number inversion”. When a positive feedback loop (forming a resonant cavity) is properly added, the laser oscillation output can be formed. The laser generator is composed of a working medium and a pump source enclosed in a pump cavity. The pump source “pumps” the working medium from the energy ground state to the excited state. If the “population inversion” is achieved between the two excitation energy levels, stimulated radiation (ie photons) can be generated, which can be amplified by resonating in the optical cavity and reflecting back and forth. A part of the amplified electromagnetic radiation is output to form a laser. The laser generator introduces the 1064nm high-power laser directly into the processing surface through a soft single-mode fiber with a sheath, and the spot size after collimation and focusing reaches tens of microns or less, which is close to the diffraction limit. This type of laser can be used for marking, etching, burning, printing, or engraving various materials.

Advantages Of Fiber Laser marking machine

Fiber laser marker machine has become a hot spot in laser physics research in recent years, and it is unanimously considered as a new generation product that may completely replace solid-state lasers. Compared with the inkjet method, the laser marking system is more environmentally friendly and economical. The long-lasting marking will not be easily erased. The non-contact and non-destructive marking will not damage the substrate. The printing accuracy is high and small. It can achieve 0.12×0.12mm 31-bit 2D code laser marking, long service life, more than 100,000 hours of continuous work, fast processing efficiency, a 2D code can be completed in less than 1 second, beautifully marked, hand-touched. There is no obvious touch on the top, manual operation is simple and fool-like engraving.

1. It can mark a variety of metal and non-metal materials. In particular, it is more advantageous to mark materials with high hardness, high melting point, and brittleness.

2. It belongs to non-contact engraving, does not damage the product, has no tool wear, and has good marking quality.

3. The laser beam is thin, the marking material consumption is small, and the marking heat-affected zone is small.

4. High engraving efficiency, computer control, easy to realize automation.

5. The best way to engrave metal without tools.

What Are Fiber Laser marker Used For?

Fiber laser marking machines are widely used in all walks of life, as long as they need to be marked. From an industry perspective, these types of laser marking machines are widely used in integrated circuit chips, computer accessories, industrial bearings, clocks and watches, electronic and communication products, aerospace devices, various auto parts, home appliances, hardware tools, molds, wires and cables, food graphic and text markings in packaging, jewelry, credit card, tobacco, military and many other fields, as well as mass production line operations, are the darlings of high-end ultra-fine processing market. From a functional point of view, it can do:

1. Black Marking on Alumina.

This is a MOPA laser technology that requires an adjustable pulse width. Unlike ordinary laser marking systems, it can make alumina black.

2. Color Engraving on Metal.

This requires some adjustments and attempts on the parameters according to the material. Various colors can be printed on stainless steel.

3. Black Marking on Metal.

Not to mention this, it’s almost the same as the second point.

4. Online Flying Marking.

What does this mean, that is to combine the laser marking machine with the assembly line, marking while feeding, so that we can greatly improve our work efficiency, for some needs to be placed on the assembly line marking is an absolute boon for marking items that are generally inconvenient to move manually.

5. Portable Laser Marking.

This type of laser machine is small and does not take up space, which can meet the basic marking needs. For customers with low marking requirements, the portable laser marking machine is very suitable. From the material point of view, fiber laser marking machines have great advantages for marking hard, brittle, and dark materials. In other words, most metal materials, as well as some specific non-metal materials such as plastics, can be used for marking. The marking effect is subject to the actual effect, some materials such as hard plastics, all fiber and CO2 laser marking machines can be used to mark, but the engraved results are different.

Of course, the prices of the two types of laser machines are also different, so customers need to be based on their own laser marking plans & projects and the cost control situation to choose.

In general, fiber laser engravers are loved by all walks of life for its price and usage cost, efficient production capacity, and powerful functions. I believe that in the near future, the laser marking opportunities will be more popular. The industry is even accepted and applied by the general public.

How Much Does A Fiber Laser Marking Machine Cost?

If you want to buy a fiber laser marking machine, you may wonder how much does a fiber laser engraving machine cost? how to get a final price? According to different machine configurations, you will get the fiber laser engraver cost from $3,500.00 to $28,500.00. If you have an idea to buy a fiber laser marking system overseas, the fee of customs clearance, tax, and shipping costs should be included in the final price.
