Hello to all!
I have a big problem in a laser cutting machine type 3015-amada fo .. is that my lens is broken and he got out of the powder (yellow) and multiplied throughout the circuit!

normally must netoyer miroire and all circuit feseau this laser is not...and that I can make me clean only

thank you rependre me as soon as possible

I can't make heads or tails of what you're trying to say. You might want to post in forum1529 and ask for some translation help. IF your lens is broken, then your laser is dead. You need a new lens.

A better translation from abeltio in the Translation Assistance forums:

I have a big problem in a Amada Laser Cutting Machine-3015 fo .. is that the lens was broken, and let out powder (yellow) that spread through the circuit!

I normally clean the exterior mirrors and the entire laser beam circuit ... can I clean everything by myself?

Best to you,

WTF, "yellow powder?" Seems to me that you need to identify the source and cause of this powder. This does not sound like a normal situation, and you may be exposing yourself and others to harmful/toxic materials.

I'll take a stab at it and say the "yellow powder" was a destroyed ZnSe lens. If that's the case, I see no problem with cleaning it up yourself... although if it's on the circuit boards, you need to be extra careful you do not break anything else while cleaning them.

You guys are awesome.

Yes the yellow powder is from the focus lens. Technically, it's nasty stuff in large amounts, from what I understand. The circuit can only be the beam delivery system. Not actual circuit boards.

But getting back to the problem. The main reasons why a lens gets fried is a pre-focused beam (power density too high for the lens), cutting without assist / shield gas, and not having sufficient nozzle gap for the gas to flow.

So, really the guy has more problems than should be addressed here. At least that is my opinion.

thank you all very much, you are really great

This is common, this is what I would do-

1. Try to control the dust it's not healthy

2. remove any bellows and any other contaminated parts and carefully take outside and blow them out. A leaf blower works great but be careful! you can burst seams

3. don't breathe the yellow dust and try to contain it.

4. Whatever is contaminated and not practical to remove from the machine like mirror mounts and whatnot, clean them out w damp rags the blow it out w air

5. don't breathe the yellow dust

put it back together and run it and WATCH THE LENS!

6. have fun translating this

Last step from Krugtech is very important. Monitor the lens very frequently at first. If any more dust falls on top of the lens, another lens will crack and you'll have clean everything again. As the lens remains clean, you can increase the lens check interval.

ha ha ha footstrap you've been through lens/output window cascade failure. Had a guy take out 3 output windows in 3 days what a freakin mess! I personally hung out there for 2 days watching the power...... Stuff that only happens under warranty..... sometimes it's covered, sometimes it isn't......

Oh yes, had my share of lens cracks. What I found out is, don't try to take any shortcuts when it comes to cleaning everything; you'll pay for it later. Just take your time and clean everything as much as you can.
