Impressive! Rock Drill Head Manufacturing Process. Heavy Equipment Factory in Korea 

Machine coolant is primarily there to reduce heat caused by material distortion. Material in lathes and mills is removed much like how a bulldozer removes material, it bunches up and folds in on itself at a microscopic level and is eventually peeled off the surface. Traditional friction in machining is not common and is highly undesirable as it can cause inconsistent forces, which causes the tool to bounce over the part. The general term is called chatter and specifically for friction based chatter it's called rubbing, this can lead to a poor quality finish which requires extra processes to remove and reduces the lifespan of the cutting tool, both increase the cost of part production. In case anyone was curious.

Lol “milk protects the tool from over heating” Milk is awesome.

I like that the cemented carbide has "blah blah features that are good for digging". 🤣

Great work and great humour.

I just love companies that have a proper box and packing is professional !!!

I am addicted to your channel. Thank you for sharing this magnificent process

I love the sound of precision metal parts fitting together.

I love these videos!

팩토리몬은......설명이 아주 친절해서 좋아요~

7:49 A group of mini-Daleks 😉

Надо в разогретую заготовку шипы вставлять. Так то они все повыскакивают.

Missile Maniac had me cracking up. Love from North America(definitely aint South). 😉 Also, the part with cutting the "spirals" would be better translated as cutting "threads."

Це фантастика. Зачаровує. Така якість, Дуже чудово. Молодці вся нація.

Very well done, as always.

And people think at $2.57 per gal is a lot and then you see just what goes in to making just a drilling bit , we shouldn't complain. These oil companies are doing a terrific job supplying our oil needs ! Let's give them some credit !

представьте себе что этого очень дорогого ( сверла ) хватает только на одну скважину (просверлить) толщу гранита глубиной всего метра 3-6. на самом деле это не сверло конечно а --ДОЛОТО победитовое , и оно не сверлит а БУРИТ..

Well done. No music. Brilliant.

i love shows like these, they show the process and how its done without some screaming maniac who cant stand to be out of the cameras view and wont stop talking. actions speak louder than words. thanks so much for your work

Beautiful work. Bravo.

Я обожаю бурение и всё что с ним связано шарошки супер точно на нефть+газ высокого качества и проходимость хорошая 😊😊😊😊

I love any kind of manufacturing process and your videos are some of the best out there. Please keep going!

I can remember the smell of the machine coolant,gives the tongue a slight oily taste . When the Pruhdoe Pipeline was being built, my mom and step dad had a machine shop that built Aluminum, articulated trucks for tundra and ice operation. We made one with an Ice drill auger so you could drive on thin ice , punch a hole and then flood the ice to thicken it quick. We made a Freezer that went to 40’ F below to freeze saltwater cubes we then practiced out self made cutting bits down in Seattle. Bigfoot was the only Monster truck at time and we took a custom Track truck to the Mudbog race at Kingdome. Had the name “Santanimal “ as our company got sued over using the name “ Cat Track.” Crystal Mountain ski resort had some , they bolt on stock axles. The heat to assemble process was cool to do , we used dry ice on inside piece when assembling aluminum rims . Even after welding the seam , they had to peen and spot weld weeping leaks. Spied a Starbucks logo girl during the Cnc portion.

I wish they chamfered the holes before inserting the carbide buttons but that's just my perfectionism talking.

Mate, please write that it is a reupload…

Then I start to imagine these bits in place and in operation. Awesome!

현대 계열 회사인데 두산 공작기계를 사용하네요 위아 공작기계를 사용해야지요

Bring your own cleaning supplies that you know work well. Including a squeegee. Perhaps also a sheeting agent for water similar to rain-x. This must be compatible with the plastic or glass they are using.

I used to fabricate the coolant tanks/conveyors/tipper bins for these machines…… nice to see them working!💪💪🍺🍺👍

오 ~이게뭐야 오늘도 평화로운 대한민국

Pakistanis, Indians, Bangladeshis: take notes and learn.

My girlfriend would love one of those, thanks!

good job.....

blah blah features are the best features

Смотрю это видео и вспоминаю сегодняшней видос из Индии, где подшипник варили сварочными электродами...))

After using these hammer bits for years it was interesting to see how they are assembled.

Hold those individual moving bearings and they render the entire unit non serviceable. It's very interesting.

looks like they need to replace the tool bit in the Larger CNC machine at the 12:40 mark, based on what the metal looks like, it should be all the same color and not lighter and then shiny etc. 👍👍🦘🦘👌👌

This is an awesome video!!!

that is NOT milk hahahaha

the editing was wild in this one haha

Its not Milk, its called Coolant or CNC Coolant ? 👍👍🦘🦘👌👌Plus used to sell it and not its all fully synthetic coolant, meaning it lasts upto 10 times longer than the traditional oil plus water?

So much fun 😅

excelente tecnologia

wow, nice work 👏 ❤

You have a great sense of humor!

Why does every one of the kinds of videos have a SPOILER PREVIEW EVERY P H U C K I N G TIME

I wonder how they replace the bits when they eventually wear down/flatten

1:59 진짜 미치셨네요❤❤cmc 잘못되면 금속조각 총알처럼 튕겨나가서 강화 유리도 뚫고 그러는데 그틈을 찍고 계시다니 ㄷㄷ😂😂

Now I want a bunch of those roller bearings and carbide buttons to play with.

The incredible minds that come up with these cnc machines are on a whole different level than your average roof and siding guy like myself. Massive kudos to them!

When Mr Kim did their underground tests... they had to buy rock drill heads from the real Korea... take that Kim... LOL...

very good

Thanks for an amazing video....❤

Why not just 3D print it. Lol, only joking.

not a missile launch planning map 😂🗺

The editing in the video is broken, there are unrelated parts of the video in the second part, the subtitles do not correspond to what is on the screen. Why upload a defective video?!

بەڕاستی کارێکی جوانە دەست خۆش❤🎉

See how old we are! Cemented carbide? Anyone? I know there's some old duffers like out there! Maybe later in the video they did that step.😊

Also how on earth is the rock drill bit going to work, when inside it is full of bearings making it spin around, so those knobs will not touch any rock surface as they should to the point of only lightly touching it etc. Now if they used hardent hi grade steel for the knob's and hi grade end bits then it would be like a tungsten carbide machining bit used on the lathes and milling machines tool bits?👍👍🦘🦘👌👌

Excelente labor.

천공 장비 해머 비트가 저렇게 만들어 지는구나~

Where is this factory located?

It's called coolant,not milk and it's a thread,not a spiral....

7:27 reminds me of Rosie the Jetson's robot.

Nice video and comments 😁😁

Thanks for sharing knowledge.

유일하게 자막부터 키고 보는 영상

Hi

Have a great video ❤❤❤❤

How many BBBBILLIONS of dollars do that cost? 🤔

@ 6:36 you wrote “ heat the body for expansion “ Is it not tempering ? Tempering involves heating the steel to a lower temperature (below the critical point) and then cooling it rapidly in air or water. This reduces the brittleness and increases the toughness of the steel.

Very interesting

Amazing Work.

Mostrar também o final da moagem.

Огонь 🔥

Very good

Baby Dalecks!!!! (Dr Who)

Fantástico o trabalho e sempre muito bem organizado!!! Abraço daqui do Brasil!

Делал такие же шарошки, только на старых советских станках 😢. Со стороны закупали только ролики подшипника и твердосплавные вставки.

Корейцы молодцы.но Российские долговечней.

Пипец шарага! Это не водопровод, чтобы так эмулься текла (весь станок загадит)! И продувать стружку воздухом это недопустимо!

Это уже было 😮 И не раз 😢

Excellent, now where can i get some of those boxes?

First happiest jobs today Japanese selling very well just buying just inside Japanese management sell in markit Japanese hot just fully foods 🍌🥭🍉people happiest enjoy eating foods picture beautiful different reply very well ❤❤❤❤❤❤❤❤❤❤

im surprised the steel isent hardened on the grinder end. and that a press fit is enough to hold the carbide buttons in place.

Excellent video, 'watched it all through.

07:40 Little Daleks 😉🤘

Wie schwere ist es auf dem Wagen wiegen ........................? Bitteschön

Carbide

Makin canggih teknologi dunia tahun ke tahun❤ Lah di indonesia makin canggih sebar isu dan adu domba😢

신기하네

Insane engineering

미국 석유 시추기 제작회사 잉가솔랜드가 개발한 암파쇄 비트가 한국의 토목 공사현장에 사용함으로써 지하층을 파내는데 엄청난 발전을 이뤘음. 칠레 광산이 무너져서 인명을 구할 때 한국 제품의 비트가 사용되었기도 함.

Tungsten bits installed? Edit: carbide bits.

I love the way the roller bearings are put together. I hate to think how much even one of the small drills cost

i dont understand why they ruined such nice finish with the weld and grinded hole

Wertvolle Stücke
