Some customer may do not know how to use the fiber laser marking machine.
This passage we will teach u how to find focus about the fiber laser marker.
So the customer could use the machine easily.
Adjusting focus’s purpose: laser is a kind of light beam of highly concentrate energy.
It can only mark on the focus point.
And we can not mark on other position.
In this case ,it should be adjusted before marking .
In order to get the best marking effect we should make the laser focus converged on the worktable.
The way of adjusting: open the fiber laser marking machine and marking software.
Then put a metal plate on the worktable ,inputting content “Text” and select the “continuous part”.
Raising and falling down the pillar to find the strongest point after pressing the mark button.
Which position is the focus：Raising and falling down the pillar after pressing the mark button.
Then watch carefully.
You will find a position which the laser is brightest and the sound of marking is loudest.
And this position is called focus point.
Also we can record the distance in order to find the position of the strongest laser marking.
For eg : F=160/163, the filed area is 110mm*110mm, the distance between edge of Lens and surface of part is 190mm (±2mm)。
