this factory belongs to a museum.

Fantastic Job! All tolerances are guaranteed less than 2 fingers.

Металл видно серый мало хрома.Чугун точно не подходит для коленвала.Напрасный труд.

i'm no crankshaft expert but i kind of think you should indicate with a dial indicator instead of a metal stick lol

The best place for the on/off switch on the lathe is definitely on the wall behind you.

Those are cast crankshaft. They don't usually last very long under high abuse. Almost all decent mordem vehicles use press forged crankshaft.

If CAD and CNC machines ceased to exist in the west, we'd be hard pressed to find enough skilled labour that could do this kind of work anymore

These guys are really skilled, OK this type of work is from a past era. They have the right work ethic and masses of skills. Very interesting.

Интересно , из чего они это лепят , если вся обработка , практически "на сухую" и все как пластилин ..

Wow amazing work

Amazing 001👍

I can see Heath and Safety standards are a priority in this machine shop.

Franchement, BRAVO ! Malgré le peu de moyens dont vous disposez, vous faites un travail remarquable.

Amazing work on primitive Victorian era lathes and machinery. These are talented machinists and mechanics but I'm sure there is a lot of room for improvement to bring it up to par with the rest of the world.

Các bạn có công cụ và máy móc gia công thủ công cực kỳ chính xác và những tay thợ lành nghề, ít người có thể làm được như các bạn, ngoài các nhà máy sản xuất động cơ. Các bạn rất giỏi I like

Very nice work

Mis felicitaciones a estos señores!! Gran actitud para el trabajo!!

Kerja yang bagus mantap selamat beraktivitas

Балансировку увидели, осталось увидеть измерение твердости шеек.

the main journal is always in perfect straight alignment😊

Highly skilled very hard working men, much respect

สุดยอดมาก กว่าจะสำเร็จ ฝีมือจริงๆ

Oh, what a great production of "high quality" parts

７０年代の日本の物作りに、何となく似ている気がします。インドだと思いますが、皆勤勉で真面目に働いています。

4 jaw chuck and he never zero'ed out a single surface. Just adjusted it with a hammer and away he goes. I wouldn't ever pay money for one of those cranks, even if I was only going to use it as a boat anchor.

but still. the amount of skill these workers have is awesome

This guy is talented ! I love the way he eyeballs the crank into around .030" then uses a stick indicator to get even closer. All brazed tools and a perfect chip mean the best that 'OL machine can make! I'd love to see what he could do with my old XLO454.

To me it looks like the material is too soft for a crankshaft. Forged steel would do better.

Mechanical Engineering is the fabrication and designing of metals. Auto-mobile Mechanics is the maintenance of motor vehicles.

Salut super technique bravo Île de la Réunion

I have to hand it to theses guys.. they got skills

incredible skills!

29:25 I like how the thing is balanced by hand

I wonder just how smooth these handmade cranks are. I am curious.

Could only survive in low shock applications like generators or automatic gearboxes with torque converters. Nowhere near a clutch. And surface hardening of random cast iron like this is a no-no...

*very cool) we don't do that)* 🔥🔥

How did they make the first piece they started with?

Good to see the workers wearing OSHA approved sandals!

I have seen some crankshaft manufacturing for 6-cylinder 3.5 liter engines. The crankshafts made here a much larger, for trucks not passenger vehicles. BMW crankshaft manufacturing seem to be more automated and there seems to be more quality control which are also automated. So where would this production method fall under in terms of durability and precision of specifications. Crankshaft has to work within an engine with other parts. So would this manual production be more accurate or less accurate?

Im a mechanical engineering student I watch this videos for my actual ojt shop

If you want avoid fatal engine damage, never use pako-tec components! Here the correct use is only for pedestals for mailboxes and flower vases.

These guys are cranking those things out!

25:53 so the same crank shaft is sold under at least three different brand names?

But what alloy, 😊what heat-treat, what surface finish, nitriding? Yes, talented and well intentioned resourceful guys. True.

No cad CNC auto feed a real talented expert

Да уж, почему не напильником шейки коленвала шлифовать ещё не начали))) Кошмарный сон Японского инженера )))

Taki wał i technologia to może być dla śilników 2 tlokowych czy max 3 tłokowych. Zasada jest jedna jeśli ktoś kupi taki wał to w naszym kraju musi iść ponownie na osiowanie, wywarzanie i szlif !!! Obowiązkowo !!!. I z nominału robi się już 1 szlif przy wale nowym jeszcze nie zamontowanym. A i tak bałbym się zkładać bo to jest plastelina. Jak by spadł z małej wysokośći to by odkształcił by się. Ciekawe jakie różnice są na wysokośći korbowodów, i chyba nie mówimy o x,00 a raczej x,0 . Bo tutaj jak w chinach byle się kręciło. A wał jak pochodzi 2 lata to max. Czy mi się tylko zdawało ale tam chyba ani razu nie użyto mikrometra !!!. Te wały są do śilników gdzie są starej daty. Bardzo mało koni ,nie wysilone lub i pracujące jednostajnie na wysokich obrotach. Bo do ciągnika strach to założyć. Jak Czop główny tylko środkowy jest sprawdzany. Nawet nie przykręćili do bloku testowego i nie pokazali jak się kręći

Это же чугун😱😎 Как можно такие ответственные детали как коленчатый вал делать из чугунного литья. Я думаю это опасно.

Considering the equipment and time given to them the 4 people on the lathes and the old fella doing the balancing did pretty well. Ive yet to see a torque wrench or new oil used on an engine rebuild in Pakistan, they just use smaller or bigger people to tighten bolts down to spec lol It's probably the same people that make the bearings so its all good lol

HE'S GOOD LOOKING TOO BASED ON THE THUMBNAIL PHOTO !!

Are they suppliers for factory or for aftermarket sparepart....?

It is a very clean well organised shop with purpose made equipment in good condition - far better than what we normally see.

Н - надёжность 😆, Т - точность 😂, У - уверенность 😜

One word: Wow!

i, too, enjoy polishing my crank

О точности металлообработки, особенно при сверлении, говорить не приходиться. Вряд ли у этих деталей большой срок службы.

Inheritance machining would for sure cry if he saw this.

see 20:11 I also want some safety shoes like that .. where does the company buy them .. they don't supply the same model to everyone ??

電動車馬達 取代 油車引擎 AI 自動化 取代 人力 之下 這技術 顯得 珍貴

Arbore din fonta?

A sneak preview of what the engine will actually sound like 😅

Open toed sandals are a great Health and Safety restriction

It is the most important part of the car or machine

As long as you will not operate it in low revs ,high load,it will be fine

I can't imagine how many of these mechanical lathes GM and Ford would have had before the CNC.

how much weight of these crankshafts?

Until the crankshaft was transferred to the grinding machine, I thought it was a pre-machining and the work would be finished with the CNC machine, then the grinding would be done.

what the hell are they doing with those lathes ..where is the gearbox ,, have they peeled it out and put it in a truck =+

Arriving at a Caterpillar factory soon!

Kills me the way they do all the machining and just throw it on the floor

Original part quality

nice work for caren sheft

Thời nay làm cũng ăn, nhưng ăn luôn từ đầu nói toẹt ra là ăn bớt để hạ giá thành còn cạnh tranh.

What I noticed is that they are very skilled and full of skill in completing their work.

Me gusta estos trabajos

This might be how they make crankshafts in third world countries. That's a manual lathe. That's not mass production, that's cave man tech at it's finest. GM Ford and Chrysler do things a lot more modern

A cast steel for a crankshaft??????????????Amazing butchery!!!!!

Fastest caliber readers on earth 😂

Soll das alles so trocken bearbeitet werden?

Вы супер!!!

the most hilarious part is the balancing of the crankshaft . all tolerances are in 2 fingers spec.

Are those crankshafts made of cast-iron?

😮😮

OLÁ. Vos informo que a mais de 50 anos passados já existia "balanceamento ESTÁTICO e DINÂMICO" . VOSSO sistema e sequencia de usinagem por vezes está invertido. Desempenar o eixo já acabado na prensa somente se for no mês de Maio. (UMA BAITA "MAITAÇÃO"). ABRAÇOS Roberto Udo Krapf

На 0,30 в чем смысл имитации балансировки вала????? А вращающийся центр не судьба использовать? И как долго эти коленвалы ходят?

That's some precision work

OSHA would lose their minds walking through that shop.

Эти ребята должны уже реактивный двигатель самолета выточить, не меньше!

Hierro fundido para un cigüeñal?, y eso que vida tiene?

@24:30, look out the window. How can these people live like this. Such filth and garbage EVERYWHERE! On the ground, on their cloths, on their tools, on the parts. I can only imagine the smell!

Long sleeves and loose clothing: check No hearing protection: check No eye protection: check Only thing missing is children and a people wearing sandals

Trabalho muito bonito. Quantas horas de serviço tem para usinar uma peça destas. Estão de parabéns. Tem minha admiração.

К чёрту закалку шеек. Через неделю за новым приедет

Is he eyeballing those cross-drillings???

Các bạn có tay nghề rất cao.nhưng phương pháp gia công nhưng chi tiết này khó có độ bền và tuổi thọ cao vì tỷ lệ sai số chỉ ở mức phần trăm .

Окупает ли данный коленвал затраченную на него электроэнергию???

It's funny how every one of these videos is sped up, yet they all look like normal people working.

Actually we use grinding Mac not lathe machine

Конец 18го века !

Good work
