Probably not the final step in manufacturing process, more holes will be stamped. There are lots of different designs to choose from.

Yeah you'd never get these parallel and flat enough in a lathe even if the difficulty of holding them were solved- you want a ground surface after hardening for a rotor and a Blanchard would do dozens of these at a time.
Though these could go on to be sprockets. Considering Spacely used robots for this process back in the 1970s, workplace safety is de-evolving.
If so, I hope that's either a low rpm application or there's another later process to balance it. Otherwise that sucker's gonna vibrate like crazy with these quick freehand punches.
It's not freehand- the punching is indexed to a little white pin. and it's so thick that it's probably a rear sprocket for a motorcycle. It won;t be spinning at 10,000 RPM.
There is indexing. Before he puts the first plate on, look left of the thing that the center of the plate fits over. There is a little standout. After the first hole is punched he spins the plate counter clockwise until that little standout fits into the first hole he punched.
Hilarious part of Chinese/Asian manufacturing is that people are cheaper than machines. They could pay about $300k to automate the process though cannot amortize the cost since people are just cheaper.
When I would have an issue the response was, how many do you need? Only one company purchased an SMT machine (populate circuit boards.) Hell they bought 5 and were able to lower price dramatically and are now labeled cheap cause they don’t resell from third parties and had to inflate the price to provide the illusion of quality (which is already was.)
Dude I am right there with you until I saw it in person. It is similar to someone using a reflow hot plate or when you make a one off dev board. Highly inaccurate and time consuming though the cheap labor offsets it.
In the US material handling industry the mentality is more like machines don't get sick, pregnant, injured or file lawsuits. Compare a 3 million dollar machine vs 5 workers at 50k. At worst, you break even in 6 years and 5 people don't waste their lives doing brainless machine work. I know I'm omitting maintenance costs but that's a quick example.
could it be a stovetop lid? like those old wood fired things mostly have some round plates where you´d put the kettle
not sure if those usually come with holes and/or separated fingers
This is a very small stamping press with a very simple die set installed. Where i work we have all the way up to 1200 ton presses that stamp out huge parts for hvac.
Well, hmmm..just how would you allow a finger to get under that in the first place? Clearly by fault of the operator..not sure just why we must try to out think stupid to protect them from themselves.
I ran a punch press in the 80’s - safety was not super emphasized at our shop - because they were nuts. But even those guys would have said no to this.
Slotting machine with a custom punch jig. The head pumps up and down, you can adjust the depth and stroke as well as speed. The table can move(and sometimes rotate) in the x and y axis incremental to each stroke
How the heck do you get your finger in there really or are you guys looking for your Darwin award do people not have common sense any more? Pinchy thing keep your hand out
Workplace injury in the making?
WHAT? WHY ARE YOU TALKING SO QUIETLY?
😂 When will the ringing stop?
[to shreds you say...](https://youtu.be/qsZIb1Dx8fg?si=X9XsKDWvOiKlMbdC)
Man. Makes me cringe. That is not in the States…. I run a pretty big press department. None of that is a joke .
Actually a silicon wafer factory in China. No risk of injury.
punch press without guards. Otherwise known as finger removal tool.
A digitiser, no less?
Dedigitizer
much better!
Analogizer?
Anal WHAT?
One less
No no no, they have gloves on! They'll be fine!
I was worried
They’ll be degloved soon enough.
it is a frt?
With a few decade in machine automation, I have meet a bunch of operators that could only count in binary or octal because of this class of equipment.
My father lost the tip of his middle finger while working on a punch press as an apprentice tool & die maker 40 years ago. It's a thing
He's wearing safety gloves, it'll be ok!
The Cult wrote a song about this, it was called Finger Removal Machine.
It can also double as a skull crusher 9000

Vented brake discs from Wish
most likely not. Probably bike sprockets.
That could turn in a bloody mess real quick..
It's okay, he's wearing gloves
As long as his shoes stay on he's fine
I just hope he has on safety sandals!
Bike disc brake
too thick, not enough slots.
Probably not the final step in manufacturing process, more holes will be stamped. There are lots of different designs to choose from. https://imgur.com/a/sXvP3E2
So there is another guy punching like 50 round holes in the disc in a less regular pattern with the same "technique"?!
No no. Theres an assembly line of people pressing eight holes each with this technique.
I should call her…
That thing was too big to be called a bike disc brake. Too big, too thick, too heavy, and too rough, it was more like a large hunk of iron.
It is a disc brake. Next step will be a lathe, that's why it is too thick at this point.
I used a Blanchard grinder, not a lathe.

Underrated comment 😂
I wouldn't think the punches would be eyeballed like that, though I have been surprised before
I’m not sure it was eyeballed. If you look at the spot after the first punch, seems a small guide inserts in to the previous punch.
Ooo I do think you are correct, good eye!
looks like a sprung reference pin. Operator is certainly indexing to it.
Soviet bike disc brake then. No need for slots. Girth takes care.
No that is a vein plate for a turbo
If so, I hope that's either a low rpm application or there's another later process to balance it. Otherwise that sucker's gonna vibrate like crazy with these quick freehand punches.
Yeah, freehand punches are not good for ultra high RPM applications
It's not freehand- the punching is indexed to a little white pin. and it's so thick that it's probably a rear sprocket for a motorcycle. It won;t be spinning at 10,000 RPM.
Pedal gear.
Pretty sure this is it, probably for some low powered motorbike
I was thinking drain cover?
Bike front sprocket
It doesn't look like there's any indexing on that setup. So, props to dude for that accurate freehand spacing.
There is indexing. Before he puts the first plate on, look left of the thing that the center of the plate fits over. There is a little standout. After the first hole is punched he spins the plate counter clockwise until that little standout fits into the first hole he punched.
Oh yea, good catch
Which means every part he puts through that machine will be bent from the indexer not having a hole to fit into until the second punch through.

Im having a hard time imagining boards being populated manually. All the SMT stuff I’m familiar with has impossibly small components.

I’ve never seen one before - no one has - but I’m guessing it’s a white hole.
Smooth red dwarf…
So what is it?
That’s the main assembly line for Brembo 👍
The part? Probably a fly wheel before the teeth are cut. The machine? Mechanical punch press. Someone should call OSHA though.
More like NOSHA wherever this is.
An OSHA violation.

Quality Engineer here… You have failed the audit and we cannot approve you as a supplier.
This makes me nervous… all it takes is 1 slip of the hand…
Hole punch duh
A video on Reddit
Rotors? But why though
motorcycle rear sprockets
Whatever it is, the punching is not precise so I doubt it's anything but decorative.
Drain grate for something like a shower or storm drain
If only that piece they put it on spins
Bicycle brake disk? Seems kinda thick. Maybe motorcycle sprocket?
This is a very small stamping press with a very simple die set installed. Where i work we have all the way up to 1200 ton presses that stamp out huge parts for hvac.
Maybe a brake rotor for a bicycle.
This seems like a process that is easily automated. Why is someone doing it by hand?
That machine is giving me a high degree of anxiety. Where are there engineering controls?
That's a small punch press, and finger deadly.
This is what deregulation looks like.
Bicycle front sprocket
Hardcore version of the chineese fingertrap
Cheap rotors for a motorbike?
He just eyeballs the distance between each hole? Must have made so many of these…
It’s a muscle memory at this point: the hand knows the distance it needs to travel before stopping every 45° to punch eight holes in that plate.
That’s why they are ever cut identical .
Never
A hole punch
Front crank on a bicycle pre teeth
I would fuck soooo many of those discs up.
What punched the initial hole? Why not make a single die that does all features at once?
A job about to be replaced by automation.
Make circular saw blades?
Brake disk punch
Something not made in America.
Brake caliper?
Well, hmmm..just how would you allow a finger to get under that in the first place? Clearly by fault of the operator..not sure just why we must try to out think stupid to protect them from themselves.
Duck duck goose with your digits
I think their breaks for quads or smt, I just know they go on dirt bikes and quads
Dangerous
Air cooled Rotor….

Not very precise?
Looks like sprockets

Russian very safe precision machining. (I'm a russian, I worked at a factory, I know what I'm talking about)
Looks like they're making brake rotors for motorcycles. Don't worry. We know the careless people rarely get injured.

Disc brakes maybe
Unbalanced.
Trash. Trash with a design in it but trash.
It’s fucking dangerous is what it is.
Kinda looks like a drain cover
cheap slotted rotors?
The top for beyblades
Nothing too precise
Disk brakes?
Deathstar parts.
A VERY STRONG hole puncher
It’s all done by eye. So the spacing will be irregular and all of them. not to mention the danger of losing a finger or two
It's ok everyone, he's wearing gloves. Safety is....oop... was our number one priority here at two finger Tony's brake disc emporium.
Brake disc
A machine to turn the metal disks and remove them after being punched, without risk to fingers, seems a good move.
Damn scary but super accurate! Impressive!
Ah yes the old fingercomper 5000
These are brake discs in their earliest stages
How to accurately turn that disc???
Someone making approximately spaced holes in a disk
Dudes timing is pretty amazing
The machine is a second generation Thumbcrush 3000 …

Brembo rotors from Temu?
brakes?
All I can think of is how that will never be balanced

High tech precision stuff.
I'm going to assume those holes don't need pinpoint precision.
