How to slove the problem that laser engraving machine can not engrave deep enough

Author : Date : 9/4/2012 8:19:35 AM
If the laser engraving machine can not engrave deep enough:

1. Can not engrave deep enough at the beginning of laser starts, kindly check with following steps:
a) Whether the supporting point of laser tube is reasonable.
b) Whether the laser power is too low
c) whether the laser path offset
d) whether laser path setting is correct
e) whether there is scratches or dirt on mirror surface
f) whther the flow and flow pressure of cooling water is normal
g) If above are in good or normal condition, then need to check the focus lens(in laser head), and see if there is scratches or dirt on mirror surface.
h) If all the above conditions are normal, then it will be the quality problem of laser tube itself.

2. Can not engrave deep enough sometimes after laser starting: First need to check if the supporting point of laser tube is reasonable; if water temperature is above 30C; if mirrors are heating during working; if water flow pressure is normal; if cooling water is clean. If all the above conditions are normal, then check laser tube.
