Hello again,
In my case (PRECITEC HEAD FIBER LASER) I have a protective window above 200mm of the nozzle, and sometimes, it gets points of "dirt" and it makes the cut unstable or it makes impossible to cut.
If it is possible I clean it, if not, I have to replace it for a new one.
Hope it...
Hello Matt,
With that image it seems a problem with unstable cutting (sometimes cuts clean other times just doesnt). This can happen because of your protective window or because of the laser centering. Did you check those?
Hope it helped.

Hello,
I think the defaults are like "guide lines" you don't need to take it as the only truth.
So if you have a pierce that doesn't make a large spatter mark you can make it shorter until you reach the point that the spatter mark affects the part.
In my opinion, when cutting stainless steel...
Hello,
I've tryed to cut HARDOX with fiber laser. 10mm, I will reply again with the data.
The quality was good and the cutting gas is oxygen.
I'm working with a 3kw laser, so in the rest I can't help you much.

Thank you Evans, for your answer, but the rate will make your cutting time, so how much do you consider the cost of the machine working 1 hour ?

Hello guys,
Well i'm trying to find out how you calculate the machine costs, I mean, how much you spent on cutting a piece?
I have one method, that was gave to me by the machine manufacturer, but this method has a lot of fails, and I can't get a constant cost with the one they gave (the...
Hello guys,
Well thank you all for the feedback.
I've had a litle time to do more experiences and I've to say that it was hard to get the results. But here they are:
1-
2-
3-
4- PARAMETER -
The parameter are the ones identified with Q1, the Q2 are other that aren't defined.
It was hard, but...
Thank you for the answers, so you think with this resonator I can manage to achieve a clean cut? I didn't had time to experiment, but i've contacted my Machine support, and they said it would be very hard to have a clean cut because i'm using the full capacity of the laser. In my opinion, I...
Hello Gotpho.
Well unfortunately i was not able to continue the tests so I could have a clean cut, but I will take your suggestion and in the next test i will let you know the result.
Thank you for the suggestion.
"Nothing is true, everything is permitted."
The table parameter its different now but the results are the same (unfortunately [dazed]), so the new one is:
Gas Type : N2
Pierce Focal Lenght : 0 mm
Pierce Power : 2800 W
Pierce Duty Begin : 100 %
Pierce Duty End : 100 %
Pierce Delay : 700 ms
Pierce Height : 2 mm
Pierce Pressure : 4 bar...
The situation is equal to me, if you can i've started a thread with SS 10mm steel take a look, i will do more experiments tomorrow then post the results. I'll keep in touch trying to help you helping me too!
I've found this...
Hello FabproHelp,
I'm having the same problem has you, but i don't even get a cut straight. Always with tons of gross. But i'm using a 2,5mm with 1,5 MPa.
I have a 3kw Rosin Laser and with Percitec laser
What is the Focus you are using?
Guys can someone help me?
I've already "destroyed" a litle of the material. Doing a lot of tests, i started changing the focus point, starting with +3 and ended with -10 (intervals of 0,5) and the best i had was with -4,5 , but never a clean cut, it ended like the one i've showed in the...
Hello Laser community, [bigglasses]
I'm a new-born graduated Mechanical Engineer, with two years in HVAC industry and now i've been challenged in a different but attractive world of manufactaring equipments to HVAC.
Well as you can see I'm new to this World, and I'm trying to find my way...
