We Break a Engine Block into Pieces and Made Disc Brake for Semi Truck #discbrake #machineshop #machinist #amazingtechnology #dieselcreek #pakistanitruck #manufacturing #machinerepair #cuttingedgetechnology #cuttingedgeeng
For those who do not know metallurgy, it is an extraordinary video. It has a series of serious errors in the production of brake discs. The molding sands mixture is made as considered by the mixer, without moisture control, permeability, etc. They use cast iron from engine blocks, which is a superior gray cast iron, but it is melted at the cubilou, where they burn a lot of coal to maintain the lamellar graphite and prevent the formation of cementite. The result will be low-quality lamellar graphite cast iron brake discs. If you notice, it does not show whether they are checked dynamically or statically. A disc like this, under brutal braking, is likely to break and cause a serious accident.
I must say all that being said, no one here in America would work like that anymore. People are too spoiled. These people seem like that have to do what they have to do. Hopefully the vehicles these brakes are going travel slow.
@@akrocuba it's not that people are spoiled. I'm a metallurgical engineer and I cast brake discs for mercedes, bearing caps and vibrochen for daewoo. I have some experience
@@stefanpopescu6479 Exactly what I am thinking. Thought they have kinda arc furnace to melt the cast iron, but then I see the coke pile... Dont think they will blow oxygen into the furnace to reduce some C..
@@stefanpopescu6479 I MEANT NO DISRESPECT AT ALL. I OBVIOSLY KNEW THAT YOU KNEW WHAT YOU WERE TALKING ABOUT. I'M SORRY IF I CAME OFF THAT WAY. I just see soo many people now in America that are simply lazy and living off the government. What those guys are doing is hard work and I'm guessing long days with no safety equipment. In America I can tell you that people are extremely spoiled. They complain about nonsense. If they had to work like that OR hunt for their own food, no one would be "offended" and no one would be "protesting" instead of working. I grew up poor like many others but worked hard to get where I'm at and then to see people get free everything and they never paid into any system, it pisses me off!! Again, no disrespect was intended.
@@akrocuba keep calm, i agree with you. I wasn't born rich either. I have not received anything from the government, I am annoyed by those who receive money without working 🙋
We can all agree that these probably arent the best made rotors, but taking in consideration of the primitive work environment, tools, and methods and all with no PPE whatsoever, that's pretty damn impressive! My hats off these skilled hardworking men.
I worked on a project in a foundry for a few weeks in the US and the guys pouring the metal had the equivalent of space suits on the entire time and 10s of thousands of dollars of PPE. Seeing these guys do it in barefeet is insane!
@@sticustom how do you guys think america was built? These dudes are doing it the way that it was done back in the day when men were men. Now it's always QQing about safety and osha and blah blah blah. This world would not have been built with you at the helm
@@captainfancypants4933 yes that’s the way it WAS done until they discovered the side effects of silicosis, asbestos in the lungs, chemical carcinogens, etc that shortened a persons life by decades. The average age of people was in the fourties’ back then, today it’s nearly 80. So you think in todays world people shouldn’t have protective equipment to prevent injuries that occur immediately or diseases that take decades to slowly kill you? These people have the rights to live a long life, not died prematurely just so the wallets of their employers get fat.
да это все мелочи, вот бы так наш русский брат работал бы на автовазе, эт ж все ручная работа не автоматизированная, знать бы кто их поставщик, понятно что из двс траков, все бы автолюбители переехали на этого производителя!
Using one of the most sophisticated highly regulated pieces of steel and turning it into low quality cast iron and milling it to look like a brake disc takes some serious skill. Best part is most people don't know they're being scammed and think they're getting a real break disk when you are just getting a shiny chunk of iron.
I work at a chrysler dealership and let me tell you man we recycle our scrap metal and it goes to china where they do the same thing just on a higher scale. Then people go to their dealer for peace of mind and oem quality but you’re actually getting Chineseium garbage. The whole world is like this in a nutshell. Make it as cheap as possible tell no one and charge a ridiculous amount.
@@clarencefoster7689i still have the factory rotors on my 1995 tahoe, they only lost 2 thousands of a inch in 290k miles, forged steel rotors that my files cant even scratch
Four things I can’t get over about this: 1) how much it reminds me of Indiana Jones and the Temple of Doom 2) that they wear sandals doing this kind of work 3) that they paint the cooing fins inside and 4). That there are engine blocks they actually scrap and don’t repair.
If I don't feel like going to work, I don't care what other people are doing. I just don't go. If I put myself in everyone's shoes, I'd be too depressed. I do what's good for me.
Yeah yeah we read the same shit on all these vids, it’s getting old. They want or need to work the way they do shouldn’t bother you. Before you had better conditions your ancestors did it tougher too, get over yourself.
in theory , the engine block needs to be washed , heated , and then molded into a mold for baking blanks , for casting . and so , you will have a lot of impurities with dirt . and impurities in cast iron create voids and cavities , violating the strength of the casting .
@@thetruejay20 I'm from Pak believe me it's not act our labour are very skilled and hardwork we even built our own weapons..it's better then and 💯 like original the problems are the equipments..and poorty
I'm in the US. The quality of aftermarket parts here has taken a nosedive the last few years. It's frustrating to get warped rotors right out of the unlabeled white boxes they all seem to come in now. It makes sense after seeing this.
coming to a Auto Zone near you soon,,,,talk about third world,,,no wonder everybody trying to jump the fence to get in to the racist country of the USA,,,sarcasm intended
A couple years ago, I put new drums on my '70 C-10. Still had the originals (at least in the front). I should have left them on there. Even though they weren't in great shape, they didn't pulsate like the brand new ones. The prices have gone up, the quality down.
Я не специалист в металлообработке, но наверное отверстия под шпильки/болты стоит позиционировать относительно центрального отверстия, а не поддерживаемого в одной точке рукой трафарета. Бедность это страшно.
Там у оправки есть проточка кольцевая. Она садится на внешний обод. Биение остается лишь на внутреннем отверстии - в данном видео не показана обработка ступичного отверстия. А все остальные кромки они обточили на станке. Не разделяю ужаса англоязычных комментаторов по поводу рецептуры. Мы не видели весь процесс варки, поэтому не можем судить о качестве. Думаю, рецептура соблюдена.
When your 18-wheel truck, carrying propane, is barreling down a long, winding, steep hill, with crumbling pavement, in the driving rain, you'll be grateful that your brakes passed their inspection!
Many years ago I used to sledgehammer engine blocks, cylinder heads and other gray cast pieces, into certain sizes, because broken up cast paid more. These guys work very hard to achieve this. I have much respect for them, as well as their sore arms and shoulders, at the end of the day.
No they are actually making fake brake disc's that will break when braking hard. India is the land of scammers, but they cannot help it they are just simple minds.
Ja klar, weil alle wo sich über die Bremsscheiben beschweren könnten, vermutlich vom Bestatter gesegnet und begraben wurden - auch eine Art von "Geschäft ohne Reklamationskunden"
These workers are Pakistani and believe me there work are 💯💪 better they do alot of hard work...skilled worked is 10 time better then machine work and more expensive..still these guys are paid poorly...I'm not forcing you but ...I knw there work I'm local...no accidents have been reported..
It's evident that many individuals commenting negatively about these disc brakes lack an understanding of the thermal dynamics and tensile strength properties of metals. It's important to note that a significant number of American bridges and buildings were initially constructed with cast iron foundations, which have proven to withstand the test of time. While alloys have since been introduced and taken their place, we still incorporate numerous cast parts in our structures and vehicles. It's essential to recognize that the disc brake isn't solely responsible for supporting the weight of a car; rather, there are four of them on a car to facilitate stopping. To those who express their reluctance to use these disc brakes on their cars, it's worth mentioning that many of our parts already come from similar sources. It's highly likely that you're already utilizing such components, although you may not be aware of it.
Я, как токарь однозначно могу сказать, что дисковые тормоза нужно обрабатывать за одну в установку на станок. Нельзя обработать левую сторону, потом перевернуть деталь, снова установить на станок и обработать правую сторону. Существуют специальные станки, позволяющие это сделать. Даже если станок супер точный и настроенный. В конечном итоге это приведёт к бинию рулевого колеса и тормозов.
Translation of the above comment: "As a turner, I can say unequivocally that disc brakes have to be machined in one setup on the machine. You can't machine the left side, then turn the part over, put it back on the machine and machine the right side. There are special machines that allow you to do this. Even if the machine is super accurate and set up. Eventually it will cause the steering wheel and brakes to run out."
I GUARANTEE most rotors bought from any parts house come from a shop almost EXACTLY like this one, nothing comes from the USA anymore, and a majority of small metal components come from india,taiwan, korea, and mexico ie. third world sweat shops,, oh i forgot viet nam, all the cheap tires come from there..
A bridge simply resting on a solid foundation is in no way the same as a vehicle having to use something like a brake disc involving multiple types of intricate moving parts on and off multiple times a day with maintenance in between, let’s actually be serious about this. The conditions a brake disc are consistently under are substantially different from a bridge foundation.
@@SmileyFace01 Assuming the lathe is square, once you machine that outer dia on the hub, it is perfectly square and centered with the brake face. If once you flip it over you grab it by that machined out diameter hub, it should remain true. Perhaps the tolerances are not as tight as you believe?
As a diesel mechanic I can promise you these are rotors for a much smaller application such as a passenger car or similar. Brake rotors for semi trucks and class 8 vehicles are much larger, heavier, and typically BOLT on to a hub using 10-12 bolts. Not the little countersunk holes you see here which are typically annoying little phillips head screws.
@@shawnsatterlee6035 I've blown up about 14 engines building big turbo's projects and mostly rod knocks everywhere inside block, but makes a hole in weakest spot , then in most cases rod snap in half or if like my engines rods are forged, engine is seized
5 лет назад я запасался пивом и безудержно смеялся под эти видео пакистанские, 2 года назад лишь слегка улыбался без пива, сейчас смотрю и думаю какой стартап замутить в гараже))
Are work tables and conveyor belts illegal in Pakistan or what? Why after every step does the material end up back on the floor? So much wasted effort and time.
@@jackking5567 if labor is so cheap maybe they could hire a couple guys to squat in front of the factory and wave at the tourists. It would make as much sense as all the wasted material handling.
Guy operating a giant gas torch barefoot. Guys handling molten metal wearing sandals. Guy operating a lathe wearing a loose billowing long sleeve shirt. Nobody wearing any safety equipment or gloves while handling toxic liquids, breathing toxic particulate, and spray fumes. This video has it all!
They are doing Hard work with Good Skill, I have not seen any where that they were cautious and care full about the Chemical Composition and Other Properties of Material as per Duty of the Component since the Part is highly responsible for safety and operation of an Auto Motive Vehicle such part failure can lead to Road Accident with various Lives to End. Any How the Process of Breaking an Engine Block is much technical and impressive.
I used to work here, don't let the video deceive you. we had great benefits, paid holidays, weekends off and even better employee discounts. the yearly bonuses were also very rewarding. we only worked 4hr shifts 4 days a week.
This explains a lot of my quality concerns when I go to my local auto parts for new rotors! I thought I was watching a vid from the 1930's. Only thing that gave it away that I wasn't was the vid quality!
Don’t know why your last name is Smart, because you’re not very smart. In many developing countries shoes are very expensive compared to the wage . And in countries that are very humid like the South Pacific, shoes can easily and quickly develop foot fungus.
I am glad to see these videos. It proves what I've always believed about some of the manufacturing processes in other lands. I'm glad to see that only the choicest scrap cast iron is used and is tested all thru the process to assure that the finished product is of correct material. In addition, the temperature control and monitoring is top notch and can not be improved on. Safety is of the utmost concern as shown when breaking up the engine block and guarding against flying bits of metal. I know they are just pouring unimportant bits of metal but they really take their care with it.
@@rainerwahnsinn9423 some of those discs will break in an overloaded 50 model soviet truck that has been rebuilt 63 times and that truck will probably kill 10-15 people due to brake failure but none of these are important. they will rebuild the truck 64th time with same quality parts untill the truck kills some other people and its no problem.
@@user-qt7rw3of9l Учитывая общий пиздец происходящего,думаю как раз таки по тупости =))) О каких то там технология обработки метала,В том числе и термической,эти ребята не слыхали даже.Да что там,они в сланцах раскаленный метал в форму заготовки заливают =)
