Fault 1: laser intensity decreased speed fiber laser engraving machine, marking the solution is not clear enough: a laser resonator is change; fine-tune the resonant cavity lenses. The best spot of the output; two acousto-optic crystal sound and light power output offset or low energy; adjust the sound and light crystal position or increase the sound and light power supply current; 3 into the off-center laser galvanometer: adjust the laser; 4. If the current is adjusted to about 20A is still sensitive and strong enough: krypton lamp aging, replacement lamps. Fault 2: krypton lamp can not be triggered (see NTP power usage manual) to buy what type of laser marking machine should pay attention to the following points: First, working with other existing methods can be solved, but if the use of the laser processing method can greatly improve product quality, increase productivity and significantly increasing the economic and social benefits of fiber laser mouse, laser engraving machine, laser marking machine should purchase; the second, in the case before the procurement of equipment fiber laser engraving machine, you need to take full account of those that match the fiber laser engraving link machining processes associated with laser processing, or employee on the equipment but also suited to it, is very beneficial to use the full range of new equipment; Third, we should pay attention to the laser marking machine processing applications and conventional machining of composite processing technology in order to take full advantage of their respective strengths.
