7.3 The engraving surface is not plain
Fault phenomenon: there is apparent spine phenomena while cleaning the bottom; when intaglio processing, there is
apparent uneven phenomena In the place of rank crossed, when Yang Eagle processing, there is apparent spine
horizontal line between the place has character or no character; the deeper clean, the more apparent phenomena.
(

)
The speed is too fast. Please reduce the processing speed.
(
b
)
The flow of the air generated by the air pump is not steady. The powder is cumulate. Regulate the blowing of the
gas, to ensure no powder adhesion, side-blowing is better.
(c) The laser path or the focus distance is not correct. Adjust the laser path or the focus distance.
(d) The focus lens is not suitable. Change the lens into short focal length lens.
2. Regular failure and obviate method
(
a
)
First, guarantee the light path is right by checking it
(
b
)
Lower the processing speed, increase the frequency of the laser output switch;
(c) Adjust well for the gas well, to ensure no flour adhesion
,
it’s better by side-blown;
(d)Adopt the short focus lens, consider the processing thickness while adjusting the Focus Lens;
7.4 Spots scattered, not focusing, lens cone heat…phenomena of laser engraving machine.
1. Fault phenomena: the laser beam machining can see yellow, and the rough beam diameter, hollow spot, when the
hands touch the focusing tube, has a heat feeling.
2. Fault:
a) Water temperature of laser tube is too high.
b) Lens pollution.
c) Laser tube holder is unreasonable, which lead to the internal tube deformation.
d) Ray path moved to one side, the focusing effect is poor, it is the main cause of focus drum heating and the sparking
in the light exit of laser head.
e) Lens is choose unreasonable, when adjusting the focus, not consider the depth of processing then caused the poor
focusing.
f) There is something wrong with the laser tube quality.
3. Exclusion method:
a) Ensure that the water temperature in the laser tube is below 32 degrees.
b) Adjust the ray path, make sure the ray path is correct and well, and consider the processing depth when adjusting
the focus length.
