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

[@BrianHeilig1]

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

[@Zappyguy111]

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.

[@7071t6]

correct and no they are all fully synthetic coolants as well. Used to sell the machine coolants. 👍👍🦘🦘👌👌

[@bxb590]

Thank You for making me smarter. I never really gave it any thought before and it makes perfect sense.

[@stevo68]

There's quite a large number of things that can cause chatter. Even having too much load on the tailstock.

[@Zappyguy111]

@@stevo68 Over loading the tailstock is one I haven't heard of before. In what way do you mean overloading it?

[@stevo68]

@Zappyguy111 . I've found that with some smaller pieces if you back the tailstock up a little bit the chattering stops. Obviously still has to be in contact with the part. Just from my experience anyway.

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

[@SlyNation]

Gotta love the milk.

[@cds957]

Milk cools better but good oil makes the cutting edge last longer.

[@leilanala]

Its not 'milk' its an oil water mixture🤔😮‍💨

[@volvodoc01]

It’s cursed milk. It gives the sickness called “death” if you drink it 💀

[@YacineDZD-nw7lb]

Where is this factory located?

[@jasonl8326]

Are those bits that are hammered into place replaceable as they're worn down?

[@7071t6]

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. 👍👍🦘🦘👌👌

[@0menadds]

@ 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.

[@dougaltolan3017]

The components are an interference fit that requires the body to be expanded via heat. Otherwise the fit is so tight, it wouldn't be possible to assemble them.

[@orchidorio]

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

[@Juzzy520]

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

[@7071t6]

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?

[@firesurfer]

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.

[@BoatbuildingIndia]

Have a great video ❤❤❤❤

[@techiestamil6511]

Thanks for an amazing video....❤

[@timothymattson3680]

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.

[@7071t6]

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?👍👍🦘🦘👌👌

[@sorou]

I'm not sure which bit you're referring to specifically, but I'm assuming the first one. Each of those cutters is part of a much, much larger assembly. Look up Roller Cutter Drill and you should find some images of full rigs

[@dougaltolan3017]

You don't cut rock, you crush it or hammer it. Several of these cutting heads are placed in an assembly so they can roll against the rock. The assembly is rotated and pushed hard against the rock. As the tungsten buttons push on the rock they make cracks. If they were used as a lathe tool or drill, they would wear out very very quickly.

[@FranktheDachshund]

Gee I bet they never thought about that.

[@gth042]

You have a great sense of humor!

[@JM-mb6tf]

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

[@magran17]

[@adeharris4457]

I used to work on these in the UK for a company called schlumberger, they were for oil rigs & the factory pressed their own industrial diamonds one drill bit would sell for £40k & that was 14 years ago!

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?!

These are not cutting or scraping tools. They are crushing tools that are pressed very hard against the rock. Thats why the cone shapes have no shaft drive to them, they are rolled against the rock.
