even so, This is one of the better shops in pakistan that I have seen. There are micrometers being used everywhere and the grinding equipment seems to be more than adequate. How can we not love these guys.
I do agree these are great guys.
Все на глаз! Какие микрометры. Ставь себе эти клапана и езди на них. В Пакистане небыл
Pakistan: The land of creativity and amazing recycling skills! 😎 That machinist is INCREDIBLY good. Even for Western standards. He works fast, precise, and to high quality. Very very impressed! 👏
This is true Engineering: The man's ability modify one piece of metal from another, and create a 'new' part where it would otherwise be unobtainable, too expensive or too long delivery. As a retired Engineer, I raise my hat to these people ! 👏
Nice job! For inlet valves that might actually work! But without heat treating not for a really long time.
Yes, and even with that shocking amount of play in his tail stock.
I'm not sure why but I really HATE these comments from you people...
@@trxtech3010 Figure out why, and give an honest answer why.
Greetings from California. Asalamu Aleikum to all. That is a Master Machinist. I don’t know his name, but Baraka Allahu Fikkum. He knows his job very well and I am amazed at his skill on all machines (Lathes) The other thing I noticed was the Clean Machine Shop. Thanks to the owner. To the videographer… get closer to the work, add more lighting to the work area, use Macro. Show the whole Shop at the start. Over all, the Video shoot was good. Thank you. My Salute to the Master Machinist. Khuda Hafiz.
I am truly shocked. A micrometer being used correctly where it's supposed to be used and no abuse of anything. Precision grinders and being mindful of heat treatment...Came here expecting the usual engineering gore, but no - everything is legit. Also the guy has some serious machining skills.
HSE would love to go in there though.... :D
And they didn't throw everything at the floor 😺😺
Beautiful work!! The precision of the valve guide fit is impressive!! As well as all the machine work. Also great that they recycle the large valve into the smaller one. I’m impressed!!
Well... machine safety is unheard of there. 😂 And -1 Point for not using that konstant torque thingy.

This reminds me of my youth when we took Chevrolet intake and exhaust valves and recut them to fit Harley Davidsons. The stem sizes were identical so it was simply a matter of cutting them to length and re-cutting the keeper grooves. You could then cut the head of the intake valves to any size you wanted up to 1 7/8" for much higher flow. The exhaust required no cutting of the valve head at all. Why did we do this you might ask? We did it because we had no money, access to a lathe, and Chevy valves were 1/4 the price of Harley valves.
No. You did that because you knew how to get girls.
Dude ... You should grow up in communism - you'd know what it's like to have no money, NO real cars, no parts, and still try to fix what is, effectively, to have anything to drive ... You have no idea what tricks were used to simply buy or get something and fix your shitty car. That was a real university of life.
I grew up in an Eastern European country, me and my brother used to do this kind of stuff a lot when fixing our russian made motorcycles. We used modified car pistons and valves/vale guides, bigger oil pumps that were made from scratch, and a lot of other parts that we got from the scrap heap for nothing. That was because we didn't have any money and good parts were hard to find.
@@carlnordstrom7533 I a documentary on Cuba that claimed the many of there classic cars have long ago been converted to 4 cylinder Diesel engines.
уважение только за то что чистое помешение и убраны станки ну и ребята мастера своего дела
I'm impressed guys, very good working efficiency. I think you guys capable to make everything!
Its incredible to think that the first all metal LATHE (Longitudinal Axis Tool Holding Equipment) was only invented (improved on wooden) in 1751 by Jacques de Vaucanson yet so many things could not be made without it. Its truly an amazing device.
Where did you get that acronym from?
I had my doubts but when he ground/polished the stems on a centerless grinding machine it changed my mind!
Places like this might be making all our spare parts for remaining western ice cars 20 years from now.
Agreed, but remember that you will have to 'refine' your own gasoline for them
@@trevorvanbremen4718 wood gasification.
love to watch these people work they are so talented and can repair or build about anything with older equipment, true craftsmen,I will bet these guys could build an engine from scratch
Wow ,I did this 10 years ago for my Honda civic head.after i got done i thought i really should have just bought them.And now i see this guy doing the same thing and it even looks like a hardinge lathe except mine had a turit head on it. but this guy puts my workmanship to shame. i had digital calipers and radius gauges. these guys had a center-less grinder and a valve face grinder.he even heat treated as best he could the valve tips.I'll bet the valves they make last for years.great workmanship.
NASA needs to hire these guys.
Despite cutting corners on almost everything, one thing Pakistan has is amazing machinists!
These guys get the job done, while us here in the "first world' sit around talking about Job Safely Assessments, what specialist equipment we need and the cost of new materials. Meanwhile the jobs done...
Yeah, without proper safety protocols in place and practice you'll be on disability with a missing limb or an eye, while they do not have such luxury accomodations of being on disability and still be able to live decently.
What about metal fatigue? I wouldn't want these in my cars engine.
Why do none of these shops use coolant on there lathe’s
You guys might consider setting yourselves up internationally as makers of custom valves for engines that have valves that are no longer available. A customer could send you the drawings or an old valve and you could make a set. There would be a lot more money to be made doing that. Cheers Stuart 🇦🇺
Good idea but any decent machine shop should be able to do this kind of work if you need a custom valve
Wow, solid floors and walls, and the right tools for that. good workshop.
Love the little fixture that turns a bench grinder into a surface grinder.
Wow..this looks like a pretty professional outfit compared to the others I've seen ...clean and well organised with adherence to standards
8 weeks to order it in by FedEx from China . Bullshit I can make 16 in an hour . LoL. Mad respect for the machine work and ingenuity.
Some old blokes were buying second hand nascar valves. A $70 valve for five bucks. Plenty good enough for land speed records :o)
Guys, this is the real green thing. The big companies would throw away these. Also they are designing parts that are not reusable and repairable..
Watching him use that cutting-machine (dunno the name(s)), then measure, then cut, then measure, etc., brings me great satisfaction.
Better than most videos, but still, quite subpar. Real valves get heat treated and case hardened. These might be good for 2500 RPM and 2500 miles max.
Some fine work!
Very good if that's all you have to get moving, but how many valves and other parts like this make it onto the aftermarket as genuine new or pattern parts. Not sure I would be happy using these valves in a heavyweight motorcycle engine, aircraft or marine engines anywhere a sudden seizure will be critical. Take this vid as a warning, only fit OEM parts to critical assemblies.
The HSS cutter in my mid 60's high school South Bend lathe just squealed on my Cushman's valves, never thought about annealing them!
Use carbide, or CBN, for hard steel. And if you are machining a lot off, you will be removing the hardened surface, so they will wear out quickly
Hi, I am going to be working at US Engine Valve (hopefully) as a Machine OP starting next week. I have orientation. I have worked around Machine's but but pretty much all have been computer operated. If anyone has any helpful tips on the interview process, things i may be able to learn before going in, and the process of creating the valves I'd be much obliged. I've never worked with a micrometer, but have seen then used. I am impressed with your speed in this video, seems you've been doing this awhile. I imagine I will need to meet this speed within my first 8 weeks on the job to keep up with production quotas.
It's common practice to wear sandals, no safety glasses and loose articles of clothing in these shops it seems. I can imagine people get hurt alot. Also some of those tools were pretty dull. Just watching those red hot chips come off like that, but he just keeps cutting with it.
They dont need cause they dont go to work high and drunk.
Bad stuff can happen when you are *not* high or drunk - which means you do not want to stack the deck against you *more* through avoidable impairment.
Valves use a hard steel, that's why the chips are red. When you cut really hard steel the swarf can be nearly white hot.
these are the people we need to send to mars
Been there, done that. Still very cool.
The Pakistanis waste NOTHING! They certainly are some of the hardest working people I've come across.
Nice.👍. Пацаны ваще ребята, знают своё дело, взяли и починили из того что было.👍
Im impressed.
good video
As a machinist, doing machine work with exposed bare feet in sandals doesn't give me a warm and fuzzy feeling.
Not that all surface treatments on the valve are removed… Dont be surprised that you blow up your engine whilst using these valves…
Great video.
Мне понравилось,молодцы.
muito bom
Pls at 14:33 what liquid is that ? Is it just water ?
A Joy to watch
Всё их преимущество в том что за три копейки они починят мотор тойоты за пол дня, пока мы будем неделями ждать запчасти, а в теперешних реалиях когда вообще не пойми что будет, эти ребята всегда смогут обойтись без поставщиков, оборудование не технологичное но допуски теже самые, в их реалиях это идеально!Вообще не ожидал конечно я такого, как мы самая трудовая страна в мире за 30 лет превратились в торгашей и просрали всё :((
Ну так может сейчас обратно начнет цениться труд производителей, рабочих, а не торгашей и маркетологов.
I don’t think anyone wants to learn or do this kind of work anymore
Were those metric mic's?
In which city this workshop is?
Hmm... I wonder if I can buy some used titanium valves with the correct diameter stem and just work the heads down.
I remember my uncle talking about doing this years ago. He would get expensive used oversized race car valves and mill them down for his street car
tebrik ederim mükembell
this is what I call a mechanic !
Rest of us calls him a machinist :)
Вроде оборудование не современное, а как технологически правильно дорабатывают клапана, особенно понравилось, что в конце закалили кончики клапанов.
т.е. взять клапан от другого мотора, переделать его -это доработка? это нищета.
@@straus8998 Нищета, это если такое делать в америке, а у них - это профессионализм. Кстати, и у нас в советское время так делали.
@@user-ul2ue9eh2f И сейчас делают,на мот Урал выпуск,из волговских.....
@@user-ul2ue9eh2f если такое делать в Америке, то это не нищета, а custom made - тоесть очень точно, индивидуально и дорого.
@Иван Иваныч абсолютно не верно.
this guy will not retire with two hands and ten fingers.
He is lucky he still has both his eyes!
Либо он пользуется микрометром на уровне БОГ, или просто изображает что что-то измеряет
Скорей всего, чисто для видео)
Думаю, что там все в автомате, может рука уже набита за 30 лет такой работы... У нас ни один токарь со стажем так ловко никогда со станком и деталью не сможет совладать..
Когда ты этим микрометром производишь несколько тысяч замеров одного размера в день, так и будешь работать.
lets talk about the heat treat of the valve stem. That is the weak link. No temperature control. Where is the draw back? testing of hardness? I didnt see any ( I do heat treating almost daily in My tool and die shop)
They also cut well past any hardness on the stem and head so the tip is only part of the problem
All the proper tools and techniques - except a startling lack of eye protection.
Practice makes a perfect... recycling is a very efficient method to reduce carbon footprint
This is the guy congratulations my friend 🇧🇷🇧🇷
Thanks ☺️

Mucho video para ver lo mismo..!!!!!
He´s so happy
Супер!!!!!
I just can't get over the unbelievable lack of eye protection given all the rotating machinery. I would have thought they were smarter than that. And I say "they" because eye protection is totally absent from this entire genre of videos. Personally I wouldn't even hammer a nail (in most instances) without eye protection. I value my eyesight.
столько желающих попасть в телевизор бегает вокруг.
Такая технология применялась в 90-е. Отсутствие запчастей на иномарки. Клапана изготовлялись из подходящих образцов Зил, ГаЗ, Мтз, мото Урал, от наминала +0.3 мм. Направляющие разворачивались развёрткой в плюс. Хотя раньше для иномарок были ремонтные клапана + 0,3 мм., заводского изготовления.
сейчас тоже начинает применяться. например бемеве для новых моторов перестает запчасти выпускать. поломался - меняйте мотор
вроде как дизель обещали....а клапана воткнули в бензиновую бошку как на змз406
@@bombidaebombidae5560 , если верить переводу, парни из клапанов дизеля делают клапана на бензин. Только разницы нет. Что на дизеле, что на бензине, тарелки клапанов привариваются к стеблю, если это не "голова" формулы -1, где клапана цельноточёные.
👍👍 Brasil 👍💯💯
Great machinist, too bad his time is not valued much. Just spent hours making a set of valves that would probably fail quickly if you ran the engine up to 5k rpms, that would cost about $20 brand new.
trippy but nice job
what's the point of this aled as the valves are not blown, especially since these are not high-end engines?!
厲害
M friend that lathe is running too fast to machine those valves you can see red hot swarf coming from the tool!!!!!
помоему для клапана сличком большие обороты на токарке
Speeds and feeds? Yes we have those
10:20 Лайк. А патрон шо, поляк?)))
Location??
Yeah, all that talk they were saying about micrometers and such, I agree with. But my question is: Why did ya'll have that old man behind bars? I mean, what threat did he pose?
Before lunch they wash thier hands in the valve stem grinder coolant.
Quality OEM components😂
Jo chahe le lo, yeh banda humey de do (take whatever, give us this person to us)
@15:12 we call kt "milk" in the "trade", but you certainly wouldn't want to drink, it or even touch it like that!!! ;)
How did that Machinist succeed to turn that thin and long valve shaft without chatter? Or maybe it chattered bit and was ground smooth..
Possible answer: light cuts, sharp tools, and “slow” feeds (relative to RPM, which looked very high.)
@@dennisyoung4631 He is actually doing the exact opposite - a very high feed combined with a heavy cut. Often trying to go slow and light makes chatter worse.
Rigid lathe, and large tool holder?
Это дешевле чем купить комплект клапанов?
Они их продают тебе, им не нужно покупать. Или ты думаешь, клапана растут на дереве, и их лопатами сбивают по осени мэнэжеры?
Да ты прям Америку для меня открыл,чесслово. Для примера: перекаленый стержень клапана может быть хрупким и запросто отломатся. Ну его нафиг такие з/ч.
@@kobrinvegas9728 Ну ты прям гений, от слова эхсперд. Интересно, как ты определишь, не вскрывая двигаьеля, какой тебе клапан поставили? Даже если твоя шарабайка разлетится после этого, судиться с СТОшником, тебе вылетит в копеечку. Так что, сиди и не умничай.
сомнительное дело конечно, Но у них вообще многое сомнительно))). Китайские клапана на древние моторы найти можно.
I am interested this business help me
Considering the hardness is gone maybe they'll work in a lawnmower for awhile.
I’m sure they’ll do fine in a 100 hp Toyota
Valves are made from several different metals in the form of discs that are stacked in the right order before forming there shape It keeps the stem straight and stops them from bending all these exotic metals form a replica of each other right through the valve . Machining them down will render them usless in a very short time He is a good machinist. But he as No knowledge of metallurgy. But He is the normal eastern chancer That engine is doomed to fail .they sound Pakistani so it figures.
Valves are made the same way, no discs stacking. They are a solid piece of steel or titanium and machined to shape and size.
You are a nut.
@@PatricioGarcia1973 With all the info at our fingertips people still make up some wacky shit. Discs of exotic metals! Lol!
Y'all should learn more about valves. Yes they are made out of different materials which is why even excessively lapping some of them can damage them and give them shortened lives. But hey what do I know? Early valves were usually just one material but engines also ran leaded gas to help preserve the valve seats.

Какова стоимость труда этих людей, головка блока на которую изготавливается клапан (могу ошибаться но вряд-ли) это кореец и стоимость клапана (берем выпускной, он дороже) 500р оригинал и 200р аналог. Вероятно сложности с покупкой деталей.
dollars ....just few dollars ...they dont have high paying customers but the same Pakistani workers who work in Kuwait ask for way more because of the shop rent is very high in Kuwait also the people are highly paid
🇧🇷👍🏽👍🏽
Ну такое. Китай забанил?))). Переделывать клапана это как и восстанавливать аккумы))).
where is your shop
How about safety glasses.
Chop, chop, grind, grind. No heat treatment and quench anywhere in sight. Rough AF... Just like the crankshaft I watched somebody weld back together - where it had snapped in the same place it was welded back together the last time it snapped. YES, welded back together on a main bearing journal....🤣
Prudence the safety goat just jumped off a cliff.
As well he should.
No, Prudence took in the ***.
