Well, where labor is cheap, we have plenty of HCNC (HUMAN-CNC) at work. I wonder how durable are these with the level of precision that is now achieved in high end robotics and CNC milling with micron level precision? I guess it is cheaper to replace these parts than the mega bucks in capital costs for the CNCs used in our western world

These guys are doing the best they can with limited tooling. Even by manual machining methods (not CNC) they are using ancient machines. Cemented carbide instead of inserts, old style tool posts (50s era), one machine even uses flat belt drive. They are using machines that went out in the steam engine era.
Right😉😉👍👍👍 Importantly, the oil passage has not penetrated the shaft, the shaft still has to go through many steps 👍👍👍👍💖💖💖👏👏 but it's a production process. that has set up machinery according to the requirements of the cylinder block before being assembled into a machine
It's not a toddlers school though where they can do "the best they can", customers are expecting year-2021 level parts. The website of Koyo Steel doesn't look like it's only targeted at third world countries.

That is what a production facility looks like when it's ONLY goal is to make good parts for a specific job. Not to keep inspectors happy or satisfy 5 layers of unneeded management etc. In this case 'good' is defined as a crankshaft that consistently gets the job done in an absolutely hellish work environment. Be very very clear. All these men would not still be employed and the person who pays them would not still be running that machine shop if they turned out bad parts. They keep the trucks and tractors running. People get their food and stuff moved because of it. They're growing their countries like we did ours.

@@222caribou Sorry about the wall of text. Honestly it depends on the company. I've worked in several production environments over the years. And they seem to fall into two very broad categories: The first is where their goal is to satisfy paperwork needs with a 'just ship it, we'll have time to fix it when it comes back mentality. And the client might just accept the part anyway...' 36" diameter water pipes with custom bends come to mind The other actually cares about what the inspector finds and adjusts processes as required to meet the clients specs.

This crankshaft is for Locally Made Fiat 480 Farm Tractor. The Tractor is also made 100% in Pakistan, under license from Fiat, in a factory, by Al-ghazi Tractors, since 1970s.
Cast cranks typically dont need to be hardened. Forgings and billet cranks are either induction hardened or nitrited. Its why you can cut a cast crank underside and not have to harden it again. U dont know what mystery metal these are made of but there is very little rust on them so they might be a nickel or chrome alloy.
Yeah…I missed that also…but I did catch the cutting tool repositioned on almost every journal ensuring a different stroke on each cylinder….or as we call it in Oklahoma a “circus crank”
@@OkFixer I was wondering about exactly that! But I assumed I was probably missing something they did to ensure the strokes being the same... but they didn't xD watching those videos I also wonder what's the quality of the iron or alloys they use seeing how they just melt bulk scrap of all sorts. do those crankshafts go through any sorts of hardening processes later on? are there half products to be finished off somewhere else?

I think "die casting material" 22:50 is not what i want advertised, because in crankshafts it means worse, not better. Crankshafts should be forged especially in this 1+ meter size.
What engine this crankshaft is used? This will work only for agricultural machinery I think. The crankshaft looks like made from cast grey iron. No heat treatment was applied. This can not be used for high-performance engines. Crankshaft made from forge steel alloyed is the way to go, a little bit hard to machine only and expensive.
I have sbc that makes 500hp and it has cast crankshaft in it and it holds up . Going on 2 years since I built it. 90 % of factory cars and trucks has cast crankshafts.
The crankshafts that come in newer truck engines are brutally strong. A Gen4 SBC cast crank will basically never fail. Some guys have taken them over 1700hp for a season of racing. Industrial engines usually require a more and not less durable piece as the engine is ran at or near peak load for hours at a time. Even the ford 300 I6 industrial and truck engines came with a forged crank as the noncommercial engines came with a casting. Passenger cars operate at less than 25% of peak load in typical environments and can use parts that are way lighter duty than I/C engines.
they clearly didn't show every step. They didn't show threading of the flywheel flange, they didn't show the finish work on the balancer side either, I'm sure the cleaning step just wasn't shown.
OK I just don't understand. When it was new the shaft was precision made? Very exact specs? So how can they remove material and change those sizes? Of course, it will look great, but it can't be the same specs? Can someone educate me on this please?
... it's being "Machined" to "One Eye Gupta Specs" 🤔 ...no Charlie's in this country, I suppose. Yeah, it's a bad joke 😄 ...but you gotta admire their ingenuity 👍 Shit like this would never get done in the U.S., cause most Industrial lathes were shipped off to Chy-na in the 70's and 80's. Or dumped in the Great Lakes 😠 Many were rumored to have been dumped in the Lakes after WWII, a friend of mine, his Dad was an machinist after the end of the war, also said so.
Yes the machining positions on the crankshaft are very sensitive, I think the main point here is the number of lathes used, apparently each lathe is set up for one position, and greatly reduces the possibility of error, but anyway I did not see No measurements should be made.
Cast Iron is still used for crankshafts on quite a lot of engines. Not even hardened or something fancy, plain basic cast iron. But most newer high torque engines require harder cranks.

These cranks look like plain cast iron not very durable, having ground crankshaft s in a auto rebuild shop ,these look of poor quality, most industrial cranks are dropped forged steel and journals are precision ground, this is not to any standard of modern precision.
Cast iron is hard on outside and much softer under the hard shell very high carbon content, good in compression but not very in sheer, cast iron has been turned on lathes for hundreds of years with out the aid of carbide , just machined at much lower speeds and feeds.
As Dennis says, this is probably ductile cast iron you can tell it by the chips. If it's alloyed with copper you can case harden it without any problem. I'm not saying that it's better than forged steel, but lately most 4 cylinder crankshaft are made this way (I don't know if these cranks are getting the case hardening though). It's the same with camshafts, they started out being forged, then casted, and now the lobes are inserts on a piece of tube.
Something we on the west take for granted. Machining a crank in the raw. Truth is only a h handful of those watching would have tge skills to to this including myself and the dude on the machinework. Wben you are in the bush so to speak, this is whats required. 3rd world ingenuity.

и хуй с ним . и такое купят
еще надо показать как льют из переплавленых пивных банок боки головок двигателей легковушек и впаривают их на экспорт
Very good👍
А как они шатунные шейки обрабатывают?
Тоже этот момент заметил и сверления продольные под масло канал не показали, хотя я только этого и ждал момента.
На Гриндере судя по всему
@@ВикторПупкин-ь8р походу их формируют при литье, вал же литой, а выходы на шейки сверлят уж вручну. с 20:20
Looks very safe!! impressive work !
а закалка?
E la bilanciatura?
These cranks look like plain cast iron not very durable, having ground crankshaft s in a auto rebuild shop ,these look of poor quality, most industrial cranks are dropped forged steel and journals are precision ground, this is not to any standard of modern precision.
Isn’t machining like common cast iron. More like Ductile or SG iron, or maybe even cast steel. Needing Carbide to turn it, so this stuff isn’t soft.
Yes. Primitive, old-fashioned. Even so, the stuff they turn out is good enough, otherwise they would have gone out of business long ago
Cast iron is hard on outside and much softer under the hard shell very high carbon content, good in compression but not very in sheer, cast iron has been turned on lathes for hundreds of years with out the aid of carbide , just machined at much lower speeds and feeds.
As Dennis says, this is probably ductile cast iron you can tell it by the chips. If it's alloyed with copper you can case harden it without any problem. I'm not saying that it's better than forged steel, but lately most 4 cylinder crankshaft are made this way (I don't know if these cranks are getting the case hardening though). It's the same with camshafts, they started out being forged, then casted, and now the lobes are inserts on a piece of tube.
many modern cranks are cast.
Is the 1st guy really turning on and off his machine by the switch on the wall behind him? lol
Everything possible in Pakistan
For goodness sake slow it down. I would actually like to watch it.
Playback speed at 1/2 on TH-cam makes it just slightly faster than real life. 1/4 speed is way way too slow.
Something we on the west take for granted. Machining a crank in the raw. Truth is only a h handful of those watching would have tge skills to to this including myself and the dude on the machinework. Wben you are in the bush so to speak, this is whats required. 3rd world ingenuity.
Amazing Craftsmanship. 👍👍👍
This is castiron crank or steel crank

Are these skills lost to programming in western countries I assume this would be done by automatic machines.
not entirely
Я конечно всякое видел, но вал должен быть цементирован, закален, отпущен, сбалансирован.
А тут индусы на коленке ать два и состряпали вал. Да, раньше так их и делали в 70 годах, но с тех пор технологии далеко ушли вперёд.
Isn't those aluminum?
делают из чугуна и чугун закаливают,но может быть много пороков в чугунном литье,скорее всего под чпу в другом месте,быстро,один токарь одну шейку,другой вторую,третий фаски ,четвертый меряет,такто чугун на истерание неплох,лижбы неронять эти валы,не ручаюсь за трещины;итак понятно что это пулуфабрикаты
