High monochromatic monochromatic laser used to characterize, where V and A button for the center frequency and wavelength of laser radiation wave marking machine, DV and DA is the spectral line width (more detailed information please refer to the laser Principle of the book;.) The best source is the original monochrome krypton lamps, and monochromatic laser light color is actually more than krypton even better on the high tens of thousands to hundreds of thousands of times. Due to highly monochromatic laser light, thus ensuring the beam can be accurately focused onto the focal point, get high power density laser marking machine, the most important thing is bound to lead to high monochromaticity is a small noise, the laser pulse Frequency can do more, do more use of laser processing. monochromatic magnitude is proportional to the laser frequency. Marking appear wavy lines, marking the first machine with a slight cry, galvanometer-driven board higher calorific value (interference occurs) Check the grounding cable is properly connected (best grounding method is: X galvanometer signal ground, Y galvanometer signal ground, shielded wire, 220V power of the earth, and marking the cabinet to be connected) After interference if the ground is still connected, first check the marking Kaka is normal (check method is to use a known good card and put tungsten steel marking laser marking machine, marking see whether there is still interference), If there is still interference, further examination galvanometer motor cable is intact, and the other cable is wound, if everything is normal, the first with a confirmed intact galvanometer driver board replaced, if not interference, you can conclude that the galvanometer driver board have a problem; if disturbed, the galvanometer motors have problems. (Of course, companies go out of laser maintenance personnel, make sure good, if the customer's galvanometer is the product of three years ago, the ability to resist interference will almost certainly leather products laser marking machine, galvanometer marking head around the subject a cell phone signal RF signal exposed motors, electrical, magnetic fields, or is Q-switch may affect new galvanometer have this phenomenon can occur) Tool Fukunaga laser marking machine _ _ Fiber Laser Marking Machine Laser Marking Machine provided by Dongguan Guan Jun Laser Equipment Limited.
