The principle of the optical fiber laser marking machine is to use the laser beam to mark permanent marks on the surface of various substances, use the evaporation of surface substances to expose deep substances, and mark beautiful patterns, characters, trademarks, etc. It has been widely used in electronic components, precision instruments, aerospace, shipbuilding, mobile phones, and many other fields. In the structure of the fiber laser marking machine, we all know that the laser is the core component. How to select a suitable laser for the fiber laser marking machine is particularly important. Especially in some special industrial applications, the requirements for the laser are more strict. What matters should we pay attention to in the selection of the laser?
The development of lasers has a history of more than 50 years H Mehmen has produced the first ruby laser in the world, the X-ray laser and the free electron laser, which are still in the research stage. The development of lasers is changing with each passing day.
With more and more kinds of lasers, lasers are divided into Q-switched lasers, ultrashort pulse lasers, pulse lasers and continuous lasers according to their working modes. According to the working medium, lasers are divided into solid state lasers, gas lasers, semiconductor lasers and chemical lasers. The wavelength of lasers ranges from the shortest wavelength of 210 A in the far ultraviolet region to the longest wavelength of 0.7 mm in the microwave band. There are thousands of laser bands, which are applied to different types of laser equipment.
In the face of such a wide variety of lasers, how to choose the fiber laser marking machine is the key.
First, we must meet our own needs to meet continuous work and harsh environmental factors.
Second, we must meet the processing accuracy.
Third, we must ensure the stability of the fiber laser marking machine during processing and the stability of the laser power output.
The following five points can be summarized.
Whether it can meet the demanding industrial working environment and continuous work, the main consideration is whether the laser has high reliability.
Whether the output power of the laser is stable or not. Some special industries require high precision. It is necessary for the laser to be able to output stably and ensure the maximum output power of the laser.
The beam output of the laser is de qualified, and the beam quality directly affects the precision of the workpiece processing.
Whether the operation is simple and reasonable to protect the laser from damage.
Whether the performance of the laser itself is convenient for later maintenance.
These problems directly determine the stability, reliability and processing technology level of the optical fiber laser marking machine, so they are the key points. I hope you can pay attention to them in the purchase or application of the optical fiber laser marking machine.
