About the laser machine you should to know something

What is laser marking?


"Laser marking" stands for marking or labeling of workpieces and materials with a laser beam. In this regard, different processes are distinguished, such as engraving, removing, staining, annealing and foaming. Depending on the material and the quality requirement, each of these procedures has its own advantages and disadvantages.

How does a laser marking machine work?

Laser technology basics

All lasers consist of three components:
1. An external pump source
2. The active laser medium
3. The resonator
The pump source guides external energy to the laser.
The active laser medium is located on the inside of the laser. Depending on the design, the laser medium can consist of a gas mixture (CO2 laser marking machine), of a crystal body (YAG laser) or glass fibers (fiber laser marking machine ). When energy is fed to the laser medium through the pump, it emits energy in the form of radiation.
The active laser medium is located between two mirrors, the "resonator". One of these mirrors is a one-way mirror. The radiation of the active laser medium is amplified in the resonator. At the same time, only a certain radiation can leave the resonator through the one-way mirror. This bundled radiation is the laser radiation.

Benefits of laser marking

High-precision marking at constant quality

Thanks to the high precision of laser marking, even very delicate graphics, 1-point fonts and very small geometries will turn out clearly legible. At the same time, marking with the laser ensures constant high-quality results.

High marking speed

Laser marking is one of the fastest marking processes available in the market. This results in high productivity and cost benefits during manufacture. Depending on the material structure and size, different laser sources (e. g. fiber lasers) or laser machines (e. g. galvo lasers) can be used to further increase the speed.

Durable marking

Laser etching is permanent and at the same time resistant to abrasion, heat and acids. Depending on the laser parameter settings, certain materials can also be marked without damaging the surface.

Laser marking machine working principle 1. The working principle The laser is gathered at the very high energy density on the surface of material. In a very short of time, the surface of the material gasification, and by controlling the effective displacement of the laser beam, accurately burned exquisite patterns or text. The laser mark is clear and permanent, can not be rubbed and changed. While the laser marking of the non-erasable coating to also have a certain anti-counterfeiting effect. Laser source   2. Eight advantages. a. Marking effect is permanent Marking will not fade due to environmental relationships (such as touch, acid and degrading gas, high temperature, low temperature, etc.). b. Marking effect has security The marking is not easy to imitate and change, has a strong security. Laser marking sample c.  Marking effect engraving high precision Laser marking machine engraved pattern beautiful and delicate, marked clear

  30W fiber laser marking machine In recent years, the application of Fiber laser marking machine in the printing field is more and more, fiber Laser marking machine can be applied to a variety of materials, including plastic and rubber, metal, silicon wafer, etc. Compared to the laser calibration and traditional mechanical engraving, chemical etching, screen printing, printing ink, etc., with low cost, high flexibility, computer control system, and laser action on the surface of the workpiece is generated from labeled strong permanent is its outstanding characteristics. At present, in the marking printing industry, Laser marking has occupied more than 90% of the market. Fiber laser marking Machine has such a large share, because it has the following eight major advantages: 1.  Permanent Such as marks will not be due to environmental relations (touch, acid and reducing gas, high temperature, low temperature, etc.). Laser marking machine samples 2.  An

For people who produce  wood furniture and make wood crafts,  the important thing is accuracy of the machine in the machining process. So if you want to choose one high quality wood cnc machine, It should be know these parts: Mini 6090 Wood cnc machine 1. The spindle. Now, most wood cnc router spindle has air cooling spindle and water cooling spindle. This is a water cooling spindle This is a air cooling spindle The water cooling spindle adopt water cycle to cooling the spindle, so the cooling effect is very good. Almost no noise, long life. But for water cooling spindle, it needs install a water pump, a little complicated. Air cooling spindle, no need water pump, very convenient to use. 2.   Transmission  Taiwan TBI ball screw Taiwan TBI ball screw. It has h igh sensitivity and h igh positioning accuracy, it c an make work more accurate. 3.   The Fuling inverter.  Fuling inverter Fuling inverter.  It can control t
