@@aiztinik Yes your correct that a true zero backlash condition is impossible, except there's backlash compensation available within the machines programs. Obviously this takes super high accuracy and build quality within the machine tools themselves and a very good initial set up, but it's certainly possible. My comparatively much more simple Newall dro on my manual mill also has the capability of linear compensation for what the dro displays under average conditions and machine movements as long as it's checked and the corrections input into the display using an independent measurement system with multiple times more accuracy. Using laser interferometers as one example.

I can imagine how a perfect fit in a single orientation can be achieved, but seeing a complex part rotated 4 times with exactly the same degree of fit is, frankly, astonishing. This is an immensely satisfying video.🙂
The pieces that fit in any of the 4 positions is what's most impressive. Most don't realize just how difficult it is to hold that kind of precision. That requires perhaps one ten thousandth (.0001") of an inch tolerance to create seams that tight and to do it on all 4 sides of a block is very impressive.
A precise 90 degree angle does not mean it'd cut you. A simple butter knife has a sharper angle than the cubes in the video and those are hardly sharp enough to cut. The main reason is because they are missing a bevel, same as these items in the video.
Actually i was least impressed by this as more than once there has been machined holes where you put DIN 6325 pin and it becomes air tight like suspension as doesn't want go in as air gets trapped in there.
@@Mesdriver Actually, CNC was developed during the second world war. The first 'prove out' of the idea was done by three machinists: one reading the X, Y coordinates out loud a few thousandths at a time, and one each on the X and Y handwheels of a MANUAL mill. Yes, they simply turned the wheels a thou or two at a time until they had gone around a contour. That showed it could be done. RS274D (basic G-code language that ran CNC's in 'the old days') history: "Developed by the Electronic Industries Alliance in the early 1960s, a final revision was approved in February 1980 as RS274D. Due to the lack of further development, the immense variety of machine tool configurations, and little demand for interoperability, few machine tool controllers (CNCs) adhere to this standard." A buddy of mine had an old MOOG mill (yes, the MOOG of synthesizer fame) that was run by paper tape with little holes punched in it, a pneumatic reader, and miles of 1/16" pneumatic piping that flipped little valves. It made the coolest sound when making holes! It was strictly point-to-point, made for drilling, not milling, but it was a money maker for him. He decommissioned it probably 20 years ago (I still have lots of the valves and the tubing! uh . . . why? I dunno!) The first CNC I ran myself was in 1985. Hand-wrote the programs using a TI calculator, keyed them in at the control one number and letter at a time, stored them on microcassettes. In 1987 or so, my brother wrote a little program called G123 that took a DXF and made a G-Code file out of it. Rather effective at the time. Now, Fusion360 is a full 3D CAD/CAM system for $450 a year! Yes, technology advances daily, yet the heart of mankind is ever the same -> broken. : - )
That cube that's flush on 4 sides is amazing!! I suppose one side is relatively easy with the right equipment, but to have them all fit together perfectly like that and still be flush side to side is just insane in my opinion!
It's actually a lot easier than it looks. the only critical area is the outside edges. so for the whole interior, you can actually give it a lot more tolerance so it won't touch. notice how the outsides are always flat planes this is so they can assemble the pieces, which won't actually fit together very well right out of the CNC, then grind them together on a surface grinder. this will true up the original stock and create horizontal scratches that hide the part line. without the scratches hiding the part line its very obvious, like on that one that spins together. they use these tricks to make the cnc look good by making flashy parts but it's deceptive marketing. if they freely fit together that good any temperature difference between the parts would lock it up solid and it wouldn't close all the way.
I'm an industrial buyer and I buy drawing based parts machined out of plenty different alloys on a daily basis. I've yet to see parts that look this good and that includes pre-covid when I still worked in the aerospace industry. Never seen a piece of AL2024 or S304L looking so hot 😍
The reason is cost. Sure, someone can make a perfect part for several times the cost but why? Would you be happy paying significantly higher prices for aesthetics alone when most industrial buyers only really want parts that conform to the drawing and are as cheap as possible? If an industrial buyer requires polishing, very low surface roughness or some other such special treatment, said information is communicated through the drawing and that then influences cost. You get what you pay for most of the time. Nobody is getting paid to made gimmicks like that.
@David Stevens I purchased in China for just a little over a year. The parts were great, AL2024 inserts that went into nomex composites. For contingency reasons, I also purchased the same parts from a UK machinist with the same .dxf just in case. A part bought in china would cost me 15€ on average, whereas the same one bought in the UK cost 90€. Lead time was shorter in China too. So it depends on who you source from, but then again I don't have 15 years of experience with China. Covid put an end to all that though...
@@xm210c Indeed, agreed. These parts are just nice on the eyes and that degree of comestic polish is restricted to visible parts only. If they aren't seen then they just need to be functional.
Parts this good are nothing new to the moldmaking industry, and the surface finish does matter. Whatever finish the mold has is what the final part is going to look like. You can even injection-mold optical diffraction grating; the feature size that will transfer over is amazing.
Stainless steel is grained so its easy to hide the line. Its the one's with the vacuum/pressure seal just by making partial contact that show true precision.
@@timhofstetter5654 if they can made the outside seamless they can make the inside seamless too they use machine and the machine are consistent with their job. They don't cheat in their work 😂
@@wabalaka1565 Of course they cheat in their work. They cheated here. That "seamless" exterior is entirely for show. There is no reason in the world for the inside to be interference-fit, and if it was... they'd never get it to fit together or pull apart without a hydraulic press. Here, it's just a stupid stunt they used to try to make themselves look fancy. They machined two shapes, one for each piece, doing no more than making sure that the two wouldn't interfere with each other, and brought all the seams out to the exterior where they're a close fit. They then ground the exterior to make those seams disappear. You can do that in your garage with a Harbor Freight belt sander.
As a cnc machinist at one time..this is amazing. I would like to know what brand machines this was done on? Was there any hand finishing/cleaning up of the parts before the final product? If so...not as amazing. It has been better than 10 years since I've touched a lathe or mill...kind of miss it! ✌️
Nicholas, to achieve this accuracy its a combination of several items such as the machine construction, controller, spindle, cutting tools/holders) environment, operator and technology (Jingdiao's on machine measurement).
@@maximusdecimus2142 The drawing exists. A manual machinist would simply walk through each geometric feature and machine it with a knee mill, possibly using a rotary table for certain features. Simple as dirt, just tedious. Anything CNC can do... manual machining can do at least as well. The only benefit to CNC is production of many (but not VERY many) almost-identical parts and the elimination of jobs. CNC isn't magic, it's only highly tolerant of tedium. CNC isn't inherently more accurate than manual work. In fact, CNC CANNOT be AS accurate as manual work can be because all encoders have limits that humans don't have and because all encoders are digital, while humans are analog. Hint: Analog is inherently always more accurate than digital is. If you don't understant how a machinist would make these things manually... then you are not a machinist and you probably will never be one.
interesting to know what the final lapping process was.... I'm wondering if they made tools to specifically lap the opposing side then took two that were lapped and combined them into the finish piece.
This can be achieved by having preloaded double ball screws. It can achieve 1 micron positioning. And very high torque servo motors. With controller capable of lookahead of 800 blocks. atleast
No, they won't. The tolerances are obviously not nearly that close and the finishes are obviously not that good. They're not even very good, they just used a cheap trick to hide the visible seams.
@@AntonySimkin That's exactly what I mean. If the guts were fitted that closely, they wouldn't be able to assemble the pieces; you need thousandths of an inch of clearance to make a slip fit; anything with closer tolerance becomes an interference fit, requiring a press to assemble and making disassembly nearly impossible because of the terrific friction and the unbroken vacuum in the male-female junctions. These guys just ground the outside to make the seams disappear. Anyone can do that with an ordinary belt sander to make very impressive-appearing work. That's been common practice for more than a hundred years.
@@timhofstetter5654 wow man thank you for the info! astonishing! it's kinda both things at the same time... genious and tricky bastard haha And yeah, you are right, if they fit so tight in such complex shapes, filling the gap with air (to unstick them) would be such a hard work... I remember playing with two polished mirrors (one polishing the another to pair them) and then with a vacuum holders (used in glass cutting jobs) we tried to separate them once clean... we even tried putting some glue and make handles - no chance... we only could do it with a very powerful stream of helium (direct 150bar through a 2mm hole)...

But they live under constant threat of authoritarian government over reaching in ways that are absolutely dystopian and companies use these people treated as machines to obtain profit margins that are criminal on the backs of these people living in nightmarish conditions so they can buy another Porsche. It's fucked.
I work in quality control and we just had some new fixtures dropped off for our precision measurement machines. I asked the machinist what he felt was his most impressive creation. He just smiled and told me he’d be right back with it. When he came back he had two close fit parts similar to the ones in the video. He placed them together and asked me to pull them apart. I couldn’t. We had to use an air hose and blast one side, where the seem was, until it popped apart. It’s crazy how accurate a person can get with CNC.
@@Uggggu You machine the part, then you grind the surface to make the joints disappear. It's a cheap trick, and it's what they did here with these parts.
Well... You're only seeing the face. We have no idea how the inner workings look. They could be .020 off. I think this is all about surface finish/polishing.
You can't make an hermetic air piston on a cilinder by just "polishing". The tolerance is less than a molecule of nitrogen on the cilinder bottom and between the piston and the cilinder.
@@framegrace1 First off it’s a nitrogen atom not a molecule. Secondly, no machine exists that is at that level of accuracy. A nitrogen atom is about 1 ten thousandth of a micron which is about 0.0000001mm.

Not when lifting and rotating to different side pairing and still maintaining a mirror seem on each combination!
@@joshuamurray9403 grind each side the same amount
영상 넘 멋집니다. 화질도 너무좋아서 계속보고싶네요^^ 감사합니다. 좋은 영상 올려주어서 화이팅입니다.

This is so satisfying, lasers and CNC technologies have set new bars in everything.
Never in my life have I observed such a precise achievement in engineering precision.
Это впечатляет, очень красиво и интересно. Точность супер.
About 1:00 that air seal was insane.
My god... The people behind these beautiful creations are true masters.
idk if anyone knows.. but they are making an actual millennium puzzle from Yu-Gi-Oh. imagine it was seamless like this?
source？
I was thinking yes please for a puzz when I saw this
This satisfies me in so many ways
I can't imagine the level of precision that requires to pull off. Probably under half a tenth
Nicholas, to achieve this accuracy its a combination of several items such as the machine construction, controller, spindle, cutting tools/holders) environment, operator and technology (Jingdiao's on machine measurement).
The machine has to be able to wipe off the dust from a metal piece without touching it to be able to achieve such tolerances. Superb work
With such high machining tolerances, you’d think they would have posted a higher definition video
With a higher quality video, it's much easier to spot the seams.
O cúmulo da perfeição.
Современные технологии впечатляют. Очень высокое качество обработки.
Ещеб людям воевать закончить. Планету отстроилиб.
I could watch that all day
When you a snapped twig that doesn't look broken when you put the two ends back together
They don't.
Para un profano será espectacular!
Para un profesional de mecánica de precisión es es pan de cada día!
Buen video!!
I wonder to what micron-level accuracy they had to machine the component to achieve such perfection.
I wonder how sharp those edges are
I've had the 'air spring' effect with an in house part and an externally produced magnet before, our machines go down to 0.1mm accuracy.
Must say, this was a very satisfying video to watch.
Boys and girls, those "simple" mould made to perfection cost in excess of 100k €
These are a design engineers dream 🙈
They're a lot less expensive if they're made manually. This is a terrible misuse of CNC.
@@timhofstetter5654 could you please elaborate? I do not understand how could one make those manually
@@maximusdecimus2142 The drawing exists. A manual machinist would simply walk through each geometric feature and machine it with a knee mill, possibly using a rotary table for certain features. Simple as dirt, just tedious.
Anything CNC can do... manual machining can do at least as well. The only benefit to CNC is production of many (but not VERY many) almost-identical parts and the elimination of jobs.
CNC isn't magic, it's only highly tolerant of tedium. CNC isn't inherently more accurate than manual work. In fact, CNC CANNOT be AS accurate as manual work can be because all encoders have limits that humans don't have and because all encoders are digital, while humans are analog. Hint: Analog is inherently always more accurate than digital is.
If you don't understant how a machinist would make these things manually... then you are not a machinist and you probably will never be one.
@@timhofstetter5654 thanks for your explanation!
@@timhofstetter5654 doesn't the machinist usually ask for money though?
Thank you TH-cam for thinking I would like this video ... I really liked this video!!!
interesting to know what the final lapping process was.... I'm wondering if they made tools to specifically lap the opposing side then took two that were lapped and combined them into the finish piece.
These Parts came of the machine like that and the sides where then surface ground together
Amazing , looks like it is CGI !!! 👏🏻👏🏻👏🏻
I'm not an engineer, but I would love to own one of these CNC precision pieces.
True craftsmanship good work
What is the CNC control used for these machines?
I was wondering what type of precision bearings & screws is this CNC machine doing this made of!
This can be achieved by having preloaded double ball screws. It can achieve 1 micron positioning. And very high torque servo motors. With controller capable of lookahead of 800 blocks. atleast
Спасайся, кто может!!! Терминатор уже здесь!!!
Я на токарном станке один в один делаю , так же получается
put them in vacuum, treat with any polisher and they weld back together in one piece
No, they won't. The tolerances are obviously not nearly that close and the finishes are obviously not that good. They're not even very good, they just used a cheap trick to hide the visible seams.
@@timhofstetter5654 you mean that only the outer border is perfectly matched? this is dirty
@@AntonySimkin That's exactly what I mean. If the guts were fitted that closely, they wouldn't be able to assemble the pieces; you need thousandths of an inch of clearance to make a slip fit; anything with closer tolerance becomes an interference fit, requiring a press to assemble and making disassembly nearly impossible because of the terrific friction and the unbroken vacuum in the male-female junctions.
These guys just ground the outside to make the seams disappear. Anyone can do that with an ordinary belt sander to make very impressive-appearing work. That's been common practice for more than a hundred years.
@@timhofstetter5654 wow man thank you for the info! astonishing! it's kinda both things at the same time... genious and tricky bastard haha And yeah, you are right, if they fit so tight in such complex shapes, filling the gap with air (to unstick them) would be such a hard work... I remember playing with two polished mirrors (one polishing the another to pair them) and then with a vacuum holders (used in glass cutting jobs) we tried to separate them once clean... we even tried putting some glue and make handles - no chance... we only could do it with a very powerful stream of helium (direct 150bar through a 2mm hole)... (sliding wasn't an option)
@@AntonySimkin Hydrogen is also a good option; its tiny atoms can get between any two surfaces made up of larger atoms or molecules; it's the ultimate penetrant. 8)
It's nano level finishing...With superb lathing and cutting accuracy....With highly alignment.
And we still can’t find out how they cut the stone blocks of the great pyramids
aLiEnS!1! 👽
They said
It's these blocks or your throats.
With stone masonry tools. Many of the techniques for splitting large stone blocks are still used today.
Breathtaking precision, but I wonder how much of a temperature difference between the two halves and they wouldn’t fit together.
I do this every day ....
Incredible, I am trully amazed. Respect!

When the seam just melts out of existence… *shudder* gets me every time
amazed
Simply amazing workmanship, the Japanese have always been known for the superior workmanship and quality of the finished product. Ty for showing us this video. Phil. Uk.
it's Chinese
Can you read? It says Beijing precision metal.
@@godurmumishot racist people can't tell different between Chinese and Japanese
@@godurmumishot yes I can read thank you but I cannot read Asian writing, only after your comment I rewatched it and yes you are right, thanks for pointing it out to me, I’ll sleep better tonight, thank you…
I often have products made in China. Business there are versatile while western companies are rigid. Already this year we started 2 new projects, the Chinese understand quickly what is required.
Yep, the Chinese are capable of extremely high quality work if you pay for that rather than getting something as cheap as possible. Your IP is not going to be safe if it's remotely valuable however.
Yeah slave labor, awful working condition, seriously unsafe environments, no regulations, and the most oppressive government short of North Korea. That's what is required to get your product made as cheaply as possible for the maximum profit.
@@n111254789 i suggest visiting China and stop thinking that t.v gives you the Truth.
@@allykhan8594 I suggest reading about what they are currently doing to the Uyghurs, their social credit system, and work practices, organ harvesting that has been going on since the 90's that they partially admitted to in 2006, and why Foxconn is covered in suicide nets and required a waiver saying your descendants will not sue in the event of accidental death or suicide.
I have many friends and associates in China, Taiwan, and Hong Kong, I don't watch TV.
What I do is help protestors avoid surveillance from facial recognition technology and their isps logging every move they make during the protests so they didn't get thrown in re-education camps or prisons. I work in the field of cyber security specifically bug bounties, penetration testing, and sometimes red teaming. So during the protests me and a bunch of co-workers setup a service that helped average not so tech savvy protestors organize without being traced using xmpp servers hosted overseas generically named apks to access the chat clients, openly hosted vpns, and the demonsaw routing network to help disguise internet traffic. I've spoke to more people in China, Hong Kong, and Taiwan than mostly anyone. I have a feeling they weren't all risking so much just to tell each other lies. China, Hong Kong, and Taiwan are all full of fantastic people who are extremely brave, hard workers, and very optimistic despite their conditions. But they live under constant threat of authoritarian government over reaching in ways that are absolutely dystopian and companies use these people treated as machines to obtain profit margins that are criminal on the backs of these people living in nightmarish conditions so they can buy another Porsche. It's fucked.
@@n111254789
I have many Uighur friends. They're right there with me watching you.
They say "he's an idiot"
I work in quality control and we just had some new fixtures dropped off for our precision measurement machines. I asked the machinist what he felt was his most impressive creation. He just smiled and told me he’d be right back with it. When he came back he had two close fit parts similar to the ones in the video. He placed them together and asked me to pull them apart. I couldn’t. We had to use an air hose and blast one side, where the seem was, until it popped apart. It’s crazy how accurate a person can get with CNC.
THAR IS NO MAGIC THIS PART WAS SIMPLY GRIND AFTER MACHINING SO YOU DON;T SE THE LINES ;BUT GOOD JAB ANY WAY
Bingo. The part is ground on the outer surfaces after it's machined.
So what? You would still see a gap if it didn't fit perfectly :)
Finally! Someone who actually knows which way the wind blows!
What does grind after machine mean?
@@Uggggu You machine the part, then you grind the surface to make the joints disappear. It's a cheap trick, and it's what they did here with these parts.
I owned a wire EDM shop for 18 years. AGIE and FANUC machines
3 of each. We did magic every day.
Thanks to China the modern technology has been made affordable in the world...
Long live China!
Really just WOW.
I wonder where is such precision been used ?
Japanese CNC machines. Gotta love them...
Well... You're only seeing the face. We have no idea how the inner workings look. They could be .020 off. I think this is all about surface finish/polishing.
Agreed the polish looks roughish on the outside, somewhere in the gr220 range
Time to put some Prussian blue in there and see how good the fit is lmao
You can't make an hermetic air piston on a cilinder by just "polishing". The tolerance is less than a molecule of nitrogen on the cilinder bottom and between the piston and the cilinder.
@@framegrace1 lol you can't machine one molecule of nitrogen.
@@framegrace1 First off it’s a nitrogen atom not a molecule. Secondly, no machine exists that is at that level of accuracy. A nitrogen atom is about 1 ten thousandth of a micron which is about 0.0000001mm.
