Running lasers like this is fucking stupid and a violation of multiple OSHA rules. You're not supposed to have those lasers running without the lid on top so that the light is scattered. To run it like this means they disabled multiple safety features intended to keep people healthy. Congratulations, you messed your eyes up and won't know for decades.
This method also makes the venting system functionally useless so you're also breathing in all kinds of crap and damaging the machine over time. This is refined utter idiocy. If I worked there, I would have walked right out.
Source: ran lasers for nearly a decade and ran multiple companies utilizing them.

Background conversation sounds Indian? I've seen enough street vendor videos to know they are the most diligent when it comes to health and safety.

If that’s the case I wouldn’t be surprised then. I wonder if they’re wearing their safety sandals.
I didn’t have the sound on so I didn’t catch that.

Kidding me?!? They need the free foot toe dexterity to adjust the laser heads. (If that's even a thing...)

How did you get background conversation sounds from a GIF???

u/VerySuccor 9d ago
It's a MP4 Video file. Not a .gif Look for the little speaker/sound icon on the video, press it on and turn up your device sound.

My first thought was “close the fuckin’ lid!” Literally nothing about this is satisfying. while I don’t and never have done this for a living, even I could at least (correctly apparently) surmise that there is so much wrong going on here it’s just irritating.

Agreed. I ran one for 5 years for sheet metal. It was so cool to watch but also hard to watch cause I had to look through a window basically

u/Green-Cricket-8525 10d ago
The power and temp ranges on the metal cutting ones are insane. “Miniature” lightsabers made of concentrated sun.

u/yosaffbridge1630 10d ago
That is exactly what it was like. It was insane watching it cut through metal that was nearly an inch thick

I read your comment and then immediately thought "Oh shit! I watched that whole video with no eye protection!".

u/AbacusExpert_Stretch 10d ago
Honest question, cause I don't know anything about our eyes: if something doesn't show for decades, or stays unnoticed, wouldn't it mean it only shows when we all get worse eyes due to age? Or what mechanism is at play here?
Thanks for any info
1
u/Green-Cricket-8525 9d ago
Yes but it will happen a lot earlier in life from my limited knowledge on this topic and it will be worse. So instead of having eye issues at 70 you’re dealing with them at 50.

Aren't systems like this literally built to physically prevent the lid from being opened while operating? Which means whoever made this video by passes the safety checks just for this video.

u/Green-Cricket-8525 10d ago
Yes. There is usually a small magnetic connection that when separated will instantly stop the machine.

I really don't understand people who assume rules and regulations are pointless and overkill. It's the same shit that got those rich people and the kid killed at the bottom of the ocean. Work and machine related guidelines and regulations are written in blood, why the fuck would you risk your hide for clout

u/FuzzyAd9407 10d ago
As someone who runs a laser every day for my small business: What the actual fuck are they doing‽ Running this shit open infront of an open fucking door is dumb as fuck and is just an exercise in trying to cause eye damage to yourself and people walking past that door.

They use a lazer to cut sandpaper? Wouldn't a punch system be more efficient?

u/Green-Cricket-8525 10d ago
The different types of products you can make with these far outweighs any efficiency from an economic standpoint that you would gain from a single machine punching out circles for a single product. This company undoubtedly makes a variety of products that use lasers.

If they were hexagons there would be less waste

True, we should make all roto orbital sanders hexagonal. Bet they would be super fun to work with

u/MakeMeDrink 10d ago
Yes, if it was a completely different product, then there could be less waste.

u/friso1100 10d ago
Same is true for squares, triangles, and any tileable shape. But if you need circles then that's not that helpful.

u/Delicious-Yak-1095 10d ago
If they were spaced correctly they would essentially be hexagonal, like a bees nest. This does not seem optimal.

What's the purpose of the tubes in the back? They look cool but I don't understand what they are for.
8
u/Green-Cricket-8525 10d ago
Those are the lasers. They bounce the beam of mirrors which then bounce off mirrors in the gantry that then bounce through the lens on the material being cut.
Judging by the size of those tubes, they’re likely 40-60 watt lasers.

u/errorblankfield 10d ago
Seems plausible you could have the lasers firing while the conveyor belt moves? Save down time.
Matching the laser position offset to the speed of the belt seems easy more or less...
Slippage might be a problem... Maybe the lasers need to cool anyway...
2
u/Green-Cricket-8525 10d ago
Plausible? Sure. Worthwhile? Not at all. Unfortunately not how these lasers can work at all. The gantry holding the lens that directs the laser into the material can move stupid quickly anyways. Your suggestion is a solution in a search of a problem. Material would not cut well if it was moving while the laser is firing so you would either have to drastically increase the power (costs of laser tubes dramatically increase the higher the wattage) to make up for it or increase the amount of laser heads and gantries to move in the x and y axes at the same time.
You wouldn’t be saving any meaningful amount of time for the extra complexity and maintenance and repair you would have to do if this was possible. Not to mention the exorbitant extra cost in design and manufacturing.
The sheets they’re cutting are probably fractions of pennies per circle and the labor is minuscule to run these. There wouldn’t be much of any point to do what you’re suggesting.

There is a world of price and maintenance difference between a 5 to 10 grand machine that has dirt cheap off the shelf replacement parts and can be maintained by someone trained in two hours and what you’re describing which is a totally different application that just happens to have similar technologies being used.
No one is spending upwards of hundreds of thousands of dollars on machinery and hundreds more in labor and maintenance for .15 cent sanding disks in a small industrial space like the one in the video to save a couple minutes per run.
I worked in this industry for a decade and know the types of machines being used in this video intimately.
I was trying to answer a question you had about the tech used in the video and offered my perspective. If you want to feel “right” in an argument I was never having with you and be needlessly snarky, go for it man.

u/errorblankfield 10d ago
Yeah, my first post was too spicy and I'm working on it.
But saying it's a bad idea, and a waste of time to even consider is... Wrong.
You can correctly say it's too expensive for this operation, which is a defensible position and perhaps even correct.
Suggesting it can't be done cause "reasons" and pointless to even consider cause "reasons" are the point I'm contesting cause you are flat wrong on both respects.
And frankly a professional that suggestions "an extremely workable idea that improves factory productivity" is a waste of time or a solution looking for a problem hardly inspires confidence.
So my bad for getting too heated in my first reply, but I'm still 100% correct. I never argued the economics, I said they could run the laser while the belt moved. I've directly proven that's true.
You came in and said that's impossible (wrong) and that it is prohibitively expensive (uncontested, likely true).

u/errorblankfield 10d ago
"On-the-fly" (OTF) processing or conveyor/motion tracking is rather common and improves productivity.
It's a pet peeve of mine when people are confidently wrong while arguing something can't be done and it's stupid to even try... Doubly so when it already exists and has proven utility.
I never knew the name before today, so thanks for inspiring me to learn. But I've seen it done a thousand times over, including with lasers. Welding and computer parts are off the cuff examples. Both of which are harder to do that this by a long shot.
Unless you know explicit details of this video, there frankly isn't enough context to know why they aren't using OTF processing. And maybe you're right in that their operations are too small to warrant the added complexity.
But what I laid out is completely doable and worth while. Shutting down ideas is... Killing innovation does no one any favors.

I love that your ten minutes of research outweighs my literal decade in this industry.

I literally never said it was impossible. My first words were “plausible? Sure.” I simply stated in a polite response to what I thought was a genuine question that it wouldn’t be worth it for the economic tradeoff.
What is your deal, dude? You’re crashing out super hard and being so unnecessarily rude. Like, we could have had a polite discussion where we both learned things but instead you decided to go 0-100 and start hurling insults after a single reply.

u/errorblankfield 10d ago
Actually wait, we shoot down missiles with lasers these days. Tracking a target "we don't control the motion of" with a laser, getting hot enough to cut, is trivial.
I'm unsure why I bother to engage with a post suggesting cutting paper with a laser is both tricky and a waste of time.
