How to deal with laser marking machine technical parameters

When the máy khắc laser sợi quang in processing.

The direct cause of the insufficient processing of depth and processing speed  are as follows :
 because  the effective power density of the laser processing is small.
For the same material, (note: not power), the optical power density refers to the power per unit area.
So The formula is: laser power density = laser power / laser spot area.

So how to solve this problem  :

First is increase the laser power  .
The second is reducing the focused spot size.
Follow the steps  :

How to deal with laser marking machine technical parameters

First,increase the laser power of final focus
1.Check the  laser tube  light outer and clean it  . 2.Check  and clean the lens  damage degree  , need replace the lens on time  .
3.check if the   light path right  or with problem ,.
When the  laser transmission ,is there have the following phenomenon:
Whether the laser pass through from the center , ,we need to ensure the laser pass through the center  .

Second  ,Reducing the focused spot size.
According to lots of application field , it’s  more effectively to reduce the spot size than enlarge  Laser tube operating current. or exchange the laser tube . also it can  saved cost  .
Which i is the  main factor for the laser spot size
Firstly  , Checking the quality of the laser spot incident on the focusing lens
If the laser spot quality are much better , the spot   size will;  smaller , and the density of the laser will be higher  .

How to solve this situation  : 
As  the following measures should be taken: 
1. Start from the hole where the laser tube exits the hole . 
 Check to determine which part has caused deterioration of the quality of the laser spot. 
2.If it is caused by a mirror, adjust or replace the mirror.
3.If the quality of the light exiting the laser tube has deteriorate.
the following measures should be taken:
 Check whether the length of the laser tube corresponds to the distance between the support points. If necessary, adjust the support point.

The correct distance between support points is: 1/2 of the length of the laser tube between two support points,
and the two ends are respectively 1/4. .
Also it may be the laser tube’s supporting direction is incorrect, so  causing the laser tube to be deformed, and rotating the laser tube several times to find an optimal support angle (direction)

Secondly , Choose the suitable focus lens  .

For the same beam , the relationship between the focus point and the focus  size :

The shorter  focus  length is , the focus point more smaller
