radiation laser cutting machine

[Lord Daz]

Hello everyone

I am a design student and university provides laser cutting machine "yueming cm1390"http://yueminglaser.com/laser-cutting-machine/laser-machine-1368.htmlCan anyone tell me if these machines are harmful to health? emit radiation that can hurt in the long run? watch laser through machine glass is harmful to eyes?

Unfortunately, no one (and I repeat no one) can give me a precise explanation and a clear answer.

Thank you for your help,

if they are marked there should not .... Hopefully.
laser is dangerous (roa, artificial optical radiation). You should look at the source class and understand how it's protected. They are usually protected properly.
only to understand, in 1997 I used unprotected measuring lasers.... We used glasses but in the evening you had red eyes. . .
give an eye to the manual
Hi.

 

[Lord Daz]

Thank you for the answer! Yes, the bubble is present, but there is also a bubble with the laser symbol that says it is harmful to the skin and eyes. Now I don't understand if you are revering to the "live" laser (so if one touches, or looks at the laser with the open machine) or in general with the closed lid.

Hi.

What is the source class?

here are the information on the website:

cutting range: 1300x900 (mmxmm)

host size: 2015x1760x1230 (mmxmmxmm)

positioning accuracy: ± 0.07 (mm)

air travel speed: 0~800 (mm/s)

voltage: ac220v ± 10%

frequency (hz): 50/60

working environment: clean, no dust or dirt less

operating temperatures: 10 ~ 40 (° c)

temperature: ≤ 80% (non-condensing)

Could you tell me more about this?

Thank you.

reddened eyes are usually compatible with standards. It means that the laser is safe but that those who use it are not limited to normal times.

but are you talking about a laser cut or a mechanical cutting machine that uses a laser ler pointing/alignment?
a cutting laser is very powerful, you should not be able to see it from the outside. if in fact from the cabin even a fleble diffuse glow means that the optical path is free and sooner or later in that point will happen a reflective piece with the right angle, and through that optical path will come out a couple of watts, enough to pierce the walls of the room.

and standards do not provide laser cutting glasses, they would simply be useless.

Are you sure you haven't removed security bands?

my questions refer to this machine: cma1390c http://yueminglaser.com/laser-cutting-machine/laser-machine-1368.html I think it's a mechanical cutting machine that uses a laser ler pointing/ alignment. correct?

Are you sure you haven't removed security bands?

Yeah, I didn't remove anything. being the car in a university I don't think security is removed... at least hopefully.. .

thanks for the advice and help!

No, it's a laser cutting machine.
the operation with open protections should be prevented from security systems, and with closed protection there are no dangers.
the other day I was at an action where among others have a laser cut of 1500w and the protezines were made of frames with transparent panel (I have no idea of the type of material) that surround the machine.

the head of the laser, as it says lightning, is protected. then there are also perimeter protections but the important thing is that the class 4 laser is protected near the emission. If any radius comes out, serious injuries may occur!

 

[Fulvio Romano]

if but if the laser cuts the piece, and you see the point where the laser meets the piece, even if through transparent material, how do you ensure that there are no reflections?

 

[meccanicamg]

generally with laser cutting machines for there is little to lever protections. However once the head is properly protected there are no more serious dangers. the protections around it serve for possible sketches of molten metal and for the glares of the metal casting.

However if you have doubts do not hesitate to contact the manufacturer and give all the explanations of the case, as well as the manual with all the risks reported and any maintenance and use operations.

 

[Lord Daz]

molten metal??? I at most cut wood often 1cm. :

I looked for the manual on the net of this car but I couldn't find it...maybe I asked the house...

Let's say if I work with this car for 2 hours a week, I shouldn't take health risks. Right?

The only thing as he said was to try not to see where the laser meets the ta taglaire piece... although it seems impossible, how do you not look at the machine while working? the other time I was cutting cardboard and luckily I was checking them out, the power was too strong and began to burn. . :-/

not to undergo are also vapours that are generated after cutting various plastics.. .

Thank you.

Sorry but you don't understand what your fears are... First you were referring generically to "radiations" and those, in the sense of ionizing radiation (x, gamma and alpha) for the production of the laser beam there are no. the only "radiations" are those related to the wavelength (usually in infrared) of the laser and which focus from the head in the cutting point vaporize the material. There's nothing else. to protect themselves from those "radiations", the machines are equipped with opaque shields around the laser source and the optical system of focusing (in the co2 laser is all voluminous) and then there are transparent protections around the machine. I assume that transparent protections are of a material suitable to effectively absorb the wavelength of that type of laser. is in fact that all even those of high power, have transparent protections and very often (almost always...) is visible during processing the cutting point and light emitted by the burning material.
There is to say that the laser you have at your disposal seems like a Chinese, and the fact that you can't find a technical manual says it long. we hope that transparent protection materials of the working area are suitable.

As far as vapours are concerned, the vapours must be properly disposed of because they can be really toxic according to the materials cut, but this exulates from the problem of radiation and laser as such. Plasma or oxyethylene cutting also develops fumes to be disposed of.[/QUOTE]
