The components of the optical fiber laser marking machine are as follows: fiber laser, digital oscillator, field mirror, marking control card, chassis and circuit. Fiber laser: IPG brand is the most used at present, and there is also SPI MOPO mode fiber laser, its market is also very promising. Second, digital vibroscope: at present, the most widely used is the German SCANlab Vibrator, as well as RAYCUS Vibrator, SUNNEYYHANS and so on. Third, field mirror: at present, the most used are domestic brands, in optical lenses, domestic effects are sufficient to deal with the most commonly used occasions, so there is no need to find imported brands. Fourth, marking control card: currently most used is SAMLIGHTML, Mark Studio, and EZCAD also has a certain market. Fifth, the case and circuit parts, this part is designed and produced by the manufacturers themselves, of course, many are custom-made, which is why so many fiber optic machines have the same appearance.
