- In this video, we bring you the entire step-by-step process of a 4 cylinder crankshaft's machining.
Machining of a crankshaft is giving it its unique shape which helps it avoid deformation during the heat treatment.
In a nutshell, a crankshaft is the backbone of an engine. It is responsible for the operation of an engine and the conversion of a linear motion to rotational motion. - ยานยนต์และพาหนะ

I have watched the entire length of the video why?..because I love my profession. I am a mechanical engineer, what memories to see those beautiful machines, lathes, milling machines, grinding machines ... I graduated from technical college and we were taught to use those beautiful machines ... today by the advancement of technology everything is CNC but the one who learned to make any mechanical part with those beautiful machines MY RESPECT.
The best feeling after leaving the mechanical workshop of the school was to see you dirty hands, dirty work clothes, because you knew you had done an excellent job. my respects to the penultimate gentleman who made the process of rectification 😂😂😂😂😂😂😂 works smoking a snuff ... that means that he loves his profession and knows what he is doing and is so much confidence that he smokes a snuff ....
Like you, I too watched the video in full length..but the reason is not like you (I'm not an engineer) ! I don't know why I like this type of mechanical activities and the people and the way they do it. And more I see..more respectful I become to the doers! But..above all, I become numb, whenever I think about the Inventors of the machines Centuries before 🤔✌
IF COMPUTERS AND CNC MACHINE STOPPED WORKING, THESE ARE THE PEOPLE THAT CAN KEEP THINGS MOVING IN SOCIETY.
REAL MANUAL WORK USING YOUR MIND TO DO THE JOB.
We are proud to be Pakistani
33:05 Проверяет уровнем, затем подбивает рукой до более точной установки! Нас , в универе , этому не учили!! Super !
Тут столько нарушений ТБ, что наша инженерша по ТБ и ОТ, сошла бы с ума) На работающем станке менять центр... Останавливать патрон с болванкой рукой... Совать руки и мерять штангелем на вращающейся заготовке... Короче - смертники какие-то.
Ну а проволочный индикатор биения и рулетка - вообще за гранью качества)))
Ну ТБ им не нужна😁. Я вот так и не дождался балансировки. Видать как и ТБ, тоже нафик не нужна.
@@user-ci3iw3ij3z там литье не самое качественное. Ковку бы он так не покрутил.
та ладно, проволока самый точный индикатор =), а на пост советском пространстве остались единицы токарей нормальных, остальные халтуру гонят похлеще этих трудяг
У них оснащение - типичное для советского завода, мотивация лучше (трезвые, работают за деньги, а не за лозунги).
Ну это ты братец не был на заводе, раз пиздишь о том чего не видел, а если видел - адрес в студию.
really love to see the quality they produced...Simply hardworking team... May Allah bless you all.
Now I know where my Dodge crankshaft was made. Thanks Gentlemen!

If I had not seen it with my eyes I would never have believed that crank shaft can be made in such like workshops or out side factories.
Brilliant Pakistan.
Just like US 1910 only dirtier.
Thanks

Show us the forged crankshafts being made now, beautiful, those guys deserve more pay for that type of work......
they actually deserve by paid by the owner of youtube channel that might earn a lot of money in their backs .
It’s really extremely impressive the amount they do with the lathe and mechanical dial indicators
there’s no digital anything nothing modern I mean we’re going back to list 20s and 30s in the USA when they made Crankshaft and machined them like this, I really enjoy this and honestly it’s all just a math problem and these guys are very sharp they do a lot with a little
hand held measuring gauges are only off during extreme changes in the shops ,temps, this walking barefoot and no gloves or face masks isnt cool
@@tomashton1781 They seem to know what works to get the job done but yeah I agree it’s amazing to me how they work on the dirty floor you know they have all these mills and stuff like that but I can’t figure out a lay some concrete lol
They seem totally happy and fine doing it
@@tomashton1781 you sooky la la must need gloves everything probably even to have a pee🤔🤔💯🇦🇺
@@DSRE535 The concrete floor would hurt their bones and joints! Man has been standing on earthen floors for thousands of years!
It comes to my mind that if you took these men and put them into a factory where there was cleanliness and the correct tooling with an update quality control department, they would be considered very valuable employees. Oh yeah, a concrete floor would be nice too. I can't imagine doing this type of machining on a dirt floor.
And imagine yourself in their place and a dummy falls on your leg, a scream and a hubbub, an Indian comes running and bandages the wound with his shirt, and no hospitalization, tomorrow again to the machine with a swollen leg and a crutch.
Sure. It's like taking a doll from a little girl and putting a real baby in her arms. The experience that she has nursing her doll can be very valuable with a real world baby.
Concrete floor! Unacceptable. Did you not see how gently he put the piece on the floor😂😂😂
@@mvcybron and the cranks bend out of center so easily, just by tapping with a hammer, and the dude just drops the 50lb piece of metal onto the floor. SMH
@@avrel1y66 there is such a terrible unemployment that behind the fence there is already a line of people who want to take the place of the patient and start earning money. Therefore, knowing this, no one will throw a part on his foot!
BTW, 40:38 - That's something over a 4" journal, meaning that's a hell of a big I-4; likely a low-speed Deisel.
1:49 - Neat chip guard.
2:10 - Doesn't waste time getting the hard skin off.
7:02 - Eyeball indicator
14:04 - McMaster doesn't offer that chip guard!
19:58 - Looks like some mis-indexing on that #2 rod journal.
21:40 - That drill jig looks to have several guide holes for the various journals.
40:50 - No rod journal grinding shown.
45:20 - Hat's off! Given what you have available, it's hard to imagine a better result.
45:50 - The only automated process is strapping!
"Freedom's Forge" (Herman) made it clear that the production rates required for the Allies' overwhelming materiel advantage in WWII was due to advances in machine tool design, allowing relatively unskilled labor to produce a 'thing' in huge quantities with little training. By comparison, these guys are highly skilled, probably years of apprenticeship, making use of crude machine tools to produce functioning IC engine parts. Slowly and expensively, regardless of their pay and even lacking basic safety gear. Take a look at any of the YT CNC crank machining vids; this would take perhaps 5 minutes with a per-unit pro-rated labor charge of a buck and a half. These guys are making the most of the plant they have; sweat equity.
Жаль термообработки нету... Хотя бы тем же твч
@@user-nf5qq2po3f думаю что шейки коленвала закалились при шлифовке и охлаждении водой. Насколько я помню серый чугун калится при 800°C и охлаждением водой
The precision comes from the repetition! After doing a thousand, they could probably do it in their sleep!!
@@garybulwinkle82 The guy has memorized most of the dimensions.. you can see him measuring and he knows what they should be.
45:40 Is that a "BELARUS" written on the box? Is that crankshafts for tractors?
में भी रिटायर इंजीनियर हूं, मशीनों की आवाज सुनकर सुकून मिलता है
It's very difficult job to machine crankshaft, I really appreciate the team for doing machining in crankshaft.
Браво!👍 Очень не простые условия и слаженная работа. Удивительно. Спасибо за видео👍
They are absolutely amazing..they can even fix a broken shaft bring it back to original specifications where as for other's a broken crank shaft is condemned...
I would take that broken crankshaft that you think is so great that they fixed & use it for a boat anchor. I would NEVER use a crankshaft that was repaired after being broken. No matter if they did their best work on it, i would NEVER use a crankshaft like that in any engine i own, or rebuild. You will NEVER get a broken crankshaft to be true, it will never hold up to a new one. You're better just to condemn a broken crankshaft & get a new one.
Yes this is hard handy work that I fully support and will buy.
The VERY FIRST person I see w/safety glasses on!! working in all these oriental videos!!!!!
Love these videos of hard working people.. Thanks for the video
عمل دقيق وشاق كان الله في عونكم
Well that was very interesting , never new there was so many steps to produce a crankshaft Peter Australia 🇦🇺
You have got a lot of learning to mate or you must be very young 🤪🤪💯🇦🇺
Pure skill reminds me of my engineering days in Sheffield in the 80s
Os cara são brabo de mas.parabens aí plo lindo trabalho.desejo a vcs todas as coisas boas.essa usinagem aí e para poucos
wonderful job, high level skills from clever employees in bad work conditions..🌹🌹🌸🌸
Amazing how these crankshaft are made and how each one goes through the machining thumbs up great video.
Parece um orquestra trabalhando em harmonia. Parabéns a todos envolvidos nesse trabalho.
Thanks to him i proud i am Pakistani
Esses caras são verdadeiros heróis. Com tanta tecnologia e ainda usinando quase que manualmente e com máquinas dos anos 30 do século passado. Tudo no muki. Trabalhei na MWM e um virabrequim desse passava por pelo menos 5 máquinas específicas para cada operação.
São virabrequins fundidos usinados em tornos velhos, qualquer um com dois neurônios consegue fazer algo nesse padrão de qualidade, kkkkk
Boa noite amigos essa fábrica de gira brequim e muito bacana vocês são feras.
Увидев в продаже , нужно брать смело .
45:36 !!! Коленвалы для трактора Беларус - точат в Пакистане!!! класс!!!
нечто подобное ставили, полёт нормальный вроде 😁
@@user-ow5te7gy5z так их для завода и точат!!! прикол в этом!
@@user-qd6hg8my1n вполне возможно, особенно если учитывать какого пахабного качества новые трактора беларус

@@user-qd6hg8my1n да, батька конечно зло
Закалка не нужна, итак сойдет 😂
Кстати я тоже удивился почему они не закаливают их , да и вообще странно что коленвалы для легендарной Toyota где-то на коленке точат , хотя и хорошо
Да да, тоже не увидел термообработки. Возможно спецом не показывают, для конкурентов)))
Зато коробка экспорт кволити))
@@Dmitrovich38 с чего взял, что для Тойоты, там вроде Беларусь написано
@@user-rd3dz1vy7t вообще-то на коробке упаковке написано было Toyota Crown
@@Dmitrovich38 не выдумывай, на коробке написано «crown steel power crankshaft», а сбоку «Belarus», на 46:00 минуте это видно хорошо Откуда ты взял Тойоту вообще загадка
а чем вы измеряли длинну коленвала? - рулеткой ! сэр))) , и какой коленвал длинны?? 38 попугаев ! -сэр)))
Ничо, они его потом по месту кувалдой подгонят. Так же как и все остальные детали.
The real good crankshafts are made by forging. Although the craftsmanship shown is great. Thanks for the nice video.
Excelente muy bueno los felicito 👍 👏 😉
Thank for sowing workshop jayahnd.
Maravilloso trabajo!! Gracias
what's great here? The crankshaft journals are not hardened! Where is heat treatment-hardening How long will such a crankshaft last before overhaul? 50 engine hours or 100 engine hours :)))
@@perisher1976 La medicion de los resultados que servira de realimentacion para modificar su proceso de fabricacion sera mas largo.(bastante)
Si los productos que fabrican,en la practica dan malos resultados, disminuira la demanda de sus productos.

Thank for sharing my friend👍
Ellerinde imkan olsa,en iyisini yaparlar.Zor koşullar altında üretim yapıyorlar. 🇹🇷🇵🇰
Nice work guys.
Amongst other things I have learned,
I have reached the stage to go from 3D printing, to hopefully become somewhat adequate at using a lathe.
Can't print some things. Have to spin and trim.
But this would eventually drive me nuts.
Did sheet metal for a while in the 80's and the only electrical tools we had were a drill and a spot welder...and a lot of holes in the roof. Rainy days sucked.
Oh...and I like those wood boxes...nice!
I wish they would show how they got both ends of the lathe offset by exactly the same distance like that. I would have thought that was insanely critical.
Just chuck a bar in the two chucks and clock true/adjust at each end.
Insanely critical is relative.
Compare the process you see here with this process; th-cam.com/video/MRlnwacph3I/w-d-xo.html
Which one would you want in your car?
@@nobuckle40 Well said, Doug. You can see the run out in the crank casting as it turns. When I was regrinding cranks we had a .0002 taper/.0005 out of round limit. I would love to see the result of putting a dial indicator on one of these “precision” cranks just to see how bad they are.
@@trebushett2079 Not exactly the way I was taught many eons ago. We were taught to use the method you describe as an initial set up. For precision work, we would set the work up with a dial indicator on both ends of the work. Our tolerance was .002-.003.

@@user-tj6iw2tr8b mostly these factories belong to Pakistan
steady, very thorough and neat greetings one profession...🙏
Mercie pour se travaille propre.
Pretty cool. A live center and go-no-go gauges would help.
yeah, it kinda bugged me too about the dead center.. but apparently it's not a problem. Maybe the frequent lathe change has something to do with it.
They use a lot of pre measured 'gauge sticks' and calipers.... so it's sort of a go-no-go setup.
Good job and creativity.
They worked with a good quality with mechanics and manpower. I think that as the company's profits increase, they can buy more modern machines and improve the production process more. To make this kind of progress, they will need expert engineers and managers. Strong arms need smart minds...!!
Excellent job man
To whom this may concern. Going by the boxes they're placing these crank shafts into these parts are used in a multitude of tractors from the Middle East, China, and India
Low rpm diesel applications?
Amazing!
انتم مهرة ،تحية من المغرب .
Amazing👍
as a lathe operator I can only advise. you better use safety glass and masker to protect yourself when turning cast iron. protect yourself, it's a very valuable asset.
And finally, fitting the dowels - beautifully done, on the piss with a big hammer!
Got to say, that’s a nice looking part.
It's just amazing, my respect for those people.
Amazing
Pakistani mind is very jenous
Lack of system
Salout Great workers
I've watched a few of these machining videos from India. This is the first one where the guy is wearing safety glasses.
really great job, does the crankshaft need heat treatment ?
Well one guy was clean. The grinder operator.
glad to see him wearing safety glasses
اللّٰه يبارك ماشاءالله عمل رائع
Т-точность👍
Fantastic workers
I want to see the box this comes in.... Brand new machined crankshaft! Made out of 60 random recycled pieces of melted metal. Forged and hand lathed and eyeball balanced for your convenience. 1 day warranty!
Magical result.
14:50 не чего-се станочек!
19:51 ровнял, ровнял и об пол опять выпрямил!
Потом где-нибудь в Москве в премиум сервисе этот коленвал в BMW loham поставят за огромные бабки 😝👍♥️
Не в Москве а в Минске в конце на коробках написано что это для Белоруссии ! Сука . А стоп а может это для Трактора Беларусь !

Step 1: Put casting into CNC machine. Step 2: Press button that says "Run". Step 3: Wait until red light comes on. Step 4: Remove newly cut crank shaft. :Step 5: REPEAT
nice, I've always wanted to be a push-button "machinist"
The first step, open youtube, the second step, cheer for the working class, the third part, criticize the capitalists
They really are geniuses... Whaooooooo 👌👌👌👌
Ya skipped polishing! Or does rubbing it with a rag pass for that?
love pakistan, the lathe operator, works in packaging and probably in accounting too.

That's some backyard machining all right.
