If you ever feel hard about your laser machine? Sometimes the machine laser is weak and strong, it’s unstable when it cutting or engraving something, but you have no idea about how to solve with it. Here we summarized some problems and how to solve with them.
Problem:The marking subject is blurred and the marking speed is too fast
Solution: marking speed too fast, so we slow down. Laser spot changes, re-adjustment, so that the laser spot to be round, such it still not works, you can contact the manufacturer.
Problem:The standard value of the switching power supply voltage of the laser has dropped. It can be measured by a multimeter. The voltage of the laser power supply 30V has dropped, which is obviously insufficient
Solution:Change a new switch power supply, and after the normal work, please adjust the laser power higher, when it come out laser light, then test the laser power supply voltage is normal or not, please keep this 5 minutes, if within 5 minutes remain in 30 v voltage not degrees, prove that switching power supply can be normal use, if not, please change to a larger power supply.
Problem:Marking line to be thick, weak marking, possible problems: the workpiece surface is no longer focused on the plane
Solution: adjust the workpiece surface to the focus, and pay attention to the future operation, once replace the marking material, remember to adjust the focal plane
Problem:The optical path is not in the position of the light entry hole of the galvanometer. This problem is complicated, and it is usually caused by the above problem of the older style machine.
Solution: 1. If the deviation is very small, how can the light beam expander to adjust the request (into the entrance of the light beam laser must be in the expansion, normal deviation is no more than 1 mm)
2. if can be more than 1 mm deviation, just wanted to move to a fixed laser, is likely to be pulled down the laser reprocessing a set of suitable the location of the laser hole location calibration. On this issue, we should not blindly adjust the optical path by adjusting the beam expansion mirror, once the deviation is too large, the laser power and laser spot shaping effect will be greatly reduced, so the laser marking effect has a great impact, which is mainly reflected in: A, the laser output power down, such processing by augmenting the laser power, greatly shorten the life span of the laser. B, laser can not completely into the field lens, in effective marking wide range laser intensity uneven c, laser into the vibration of certain Angle lens, computer software set ZX deviating from the vibration lens optical physics ZX, Marking will have obvious unadjustable distortion D, serious deformation of light spot, can not play a light spot beam expansion effect.
Problem:The version of the marking software was changed, and the mode of laser light was not selected
Solution: Re-select the correct light outlet mode
