I used to work in a warehouse that manufactured the rolls that roll steel into sheets for car body's and appliances. Some of the large ones weighed 560,000 pounds plus. Every five years or so we'd get a roll that had an air bubble in it (mostly cheap ones of Chinese origin) the pressure was so great that sometimes they would spontaneously explode, most often in storage but sometimes when the lathe would start cutting it would literally explode with no warning except for a loud ping as it starred to split. We'd have to cover them with massive cargo nets to keep the pieces from flying across the warehouse, which is nerve racking. Some of the larger rolls (200,000 ibs+) could only be transfered by modified train cars. Crazy thing seeing the damage a 10,000 pound razor Sharp shard of steel can do when it flus 70 feet across the warehouse!
Some places have small blankets to throw over one when it starts. Also saw a steel ladle trunnion fail. It wasn't even lined yet, an empty ladle. The trunnion just popped out. It was Chinese, and cost within 10% of a real ladle.
I worked at a place that did this type work in So California. This looks like a blank for a generator rotor or steam turbine shaft. The job requires slow rolling until you get through the bark but then the chips should fly after verifying no cracks or defects. They also use this lathe to rough cut and net shape it and then put it another, possibly CNC lathe for finishing. Notice the feed rate was somewhere around .035 to .055 inch. They are also slow rolling it to keep it straight as the weight will cause it to sag (no kidding). They should have a steady rest just under the shaft (but not touching anything) at the tailstock end in the event the center fails. Also notice they are cutting toward each other. While this negates the thrust load on the center (that is a lot of weight on the center regardless which way the cut is going), it also cause one worker to have to stop when one cut gets too close to the other. Start both cuts from the tailstock end and push toward the headstock to reduce thrust on the tailstock and the center bearings. No chip pans to catch what is hitting the floor; labor must be cheap there. No one was wearing safety glasses. The exposed motor drive coupling and fall hazards were all danger points for me. Not a US job either.
Will W. This is why steam turbines never stop turning while in port as the tolerances are so close that while they are hot the shaft would sag and touch the stator with the rotor blades
+Will W. To pick up iron or steel chips easily, put magnet in a plastic bag, trail it over the chips to pick them all up, then turn the plastic bag inside out. Or use a jute bag if it's big chips and a big magnet!
Yeah, all that lack of safety equipment makes it look like a US shop from the 1950s. Or in other words, some time back when the US was a lot more industrially relevant.
A very old mate of mine who is considerably older than me had told stories of this kind of thing , he was a lathe operator and used to make stuff for me, even carburettor needle valves in brass. I used to take it all with a pinch of salt when he said he made prop drives for ships, especially the Royal Navy , he used to read a book while working? his job was sitting on a seat that moved back and forth with the lathe cutting tool and each cut too the best part of two hours, how long was the damn thing. Boring job though, but he liked it, bless the old bugger.
When I first started at Vickers in Barrow in 1978 that propeller shaft lathe was still there, complete with ride on carriage. Long gone now of course but it shows we could do all this stuff in the UK not too long ago.
boring?? well, i did it for over 30 yrs and it gets into your blood. i get a strange perversion watching the huge chips being cut. hahha. anyhoo, i wish i was working on big things like this.
"Day 58 since the work on the Lathe has begun... I'm starting to think the Boss Cho is about to realize that I screwed up when we mounted the shaft onto the lathe and that it's off center...

Normally, I'd just buy a tool for this job, but at these dimensions, a quality reamer can be quite expensive. Plus, there's something so satisfying about turning 120 tons of metal in a lathe. Especially when it comes to using the hand-graver for the finishing details.
The largest I have ever experienced was a 96 ton crankshaft being turned in the workshops of a shipyard in Rotterdam back in 1963.The chips coming off the rough casting were almost red hot.Very impressive.Thanks for the clip.

Mr3wheeledbike Yeah calling this thing heavy dude, is like saying Everest is a small hill. Humans can really suck sometimes... but sometimes, we make shit like this and I find that incredible.
Likely that they’re starting in the middle to prep for a steady rest. Other comments say they should use one but you can’t until the part is round. Rpm’s aren’t crazy slow, idk what that part is but 48” diameter at 250sfm is 19rpm. Some cold air coolant on the tools would help the chips break and improve tool life but everything looks pretty good, aside from obvious safety concerns there’s no need for criticism here. Machine has enough torque to handle low rpm’s, tool isn’t skipping or screaming, pressure is good and there’s very low vibration. Assuming they’re using carbide the blue chips are happy chips, a little long here and there but they’re happy chips and that’s what you want. Happy chips means happy tools and happy tools last longer and cut better.
"We are a very professional heavy duty lathe machine manufacturer" Indeed, that looks very professional at 0:51 where a spanner is crudely welded to each of the chuck jaw bodies to prevent them from becoming undone when the lathe is running. What a bodge up solution that is!
In the late 90's I worked with a machinist that worked for Argonne National Lab. He said he worked a lathe similar in size cutting a piece of stock 6 feet in diameter. He said it would take an entire shift to make one pass.
This forging was created by open-die forging. There was no specific tooling. There is no forging press in the world that could create a shaft of this diameter in 4-5 blows.
Amazing! (That it takes three machinists, one factory supervisor and a politician with a cameraman to do a job that should be entirely automated with one quality assurance machinist!)
For all those commenting on the slow speed: I see the chips coming off the blade in a dark blue color, which is I believe just right. It is neither too slow, or too fast for the feed rate and the cutting depth
franksalterego There also would be 1/3 as many guys watching it turn, and the rough forging wouldn't have such a scabrous surface, and the metallurgy would be more certain... And, the workers would be wearing eye protection, and not standing on the apron...
Not so fast and not so big. I worked some years in a geman plant. Chips with 3 mm thickness an 60 mm width were standard. Biggest horizontal lathe 4 m diameter and 28 m wide for raw forgings up to 350 to. Generator and turbineshafts for powerplants. Rpm three times more of that while machining 2 m diameter
Yes, one big lathe. The blower motor for the mail driver motor is bigger than my lathe motor. All that in mind, can you imagine the tools and forge that it took to forge that blank? Man, would make my hammer extreeeeeemly inadequate. But I guess it isn't how big it is but how well you swing your hammer................or something like that.
duringWWII the ship builders had to build huge machine tools almost over note to meet the launch dead lines , several lathes in Norfolk and Philadelphia used RR tracks for the bed and the head and tail stock were cast in concrete to save time and money . there is a club of hobby machinists now that build concrete machine tools to keep that practice alive neet stuff too
Robert Palmore I just want to know how the hell they centred the job on that monster and what kind obviously its a 4 jaw chuck but the tale stock how is it held in it would need hydraulic assistance for sure
Breaking good Not sure how they did it but to put the center on the tail stock end, I would measure a couple dozen times around and take a best guess on the center drilling for a live center point. This can be don on the ground. Lifted into place leaving it on the hoist to get the 4 jaw eyeballed in and tail stock into place. Let go and start final centering in the 4 jaw. Not precise but guessing there would be enough metal extra to accommodate this approach. That forging is rough so guessing would be over sized for just for these kinds of things.
My first job in a machine shop was turning shafts like this for natural gas compressors. 40-60 rpm is reasonable for that diameter. That scale on forgings is brutal. The carbide inserts get ate up quickly. I want to see them turn it 3 inches out of center next to cut pins for a crankshaft. :-) I learned to machine spinning 3000 pounds, 3 inches out of center.
you have it right . I did the same type of turning on large forgings . these people on here can't even figure out SFM . Gotta laugh. I would like to know how they even know the feed rate lol
Very entertaining how many people in the comments have suggestions as to what needs to be changed to improve this process. Maybe all those people don't understand it; A facility with the scope and mechanical aptitude to transport, manipulate, and machine parts of this scale certainly have several engineers on the payroll. Do you actually believe that they overlooked determining the optimal angular speed or tooling selection of this lathe? Welcome to the Internet, where people love to inflate their egos and pretend to be superior to others in a safe environment where said others and onlookers cannot know true identities and prove that the douchebag know-it-alls do not have the credentials to be making remarks.
For a rough workpiece like this forging, I wonder how they center it on the faceplate and tailstock. What part of it do they measure to judge whether it's centered? I imagine if you're not careful, you might end up getting the end centered, but then have a dent near the middle that makes it impossible to get the finished diameter you need?
THE CLEANLINESS OF THE SHOP AND WORKERS IS A DIRECT RELATION TO THE QUALITY OF THE PRODUCT. ALL THE MATERIAL ON THE FLOOR IS NOT A SAFE OR QUALITY ENVIRONMENT. IF I WERE TO TAKE A TOUR I WOULDN'T BE IMPRESSED. THIS IS A HUGE PART TO MACHINE. GOOD LUCK. HOPE YOUR NEXT VIDEO SHOWS A CLEAN PROFESSIONAL MACHINE SHOP. JUS GIVING YOU SOME PROFESSIONAL ADVICE.
That has GOT to take weeks to turn that forging to a final dimension! Makes you appreciate the precision needed in the forging process. Have to get it big enough to be able to turn a clleanup but not so big that it takes several passes.
+Barnekkid I'm sure because if that one guy fucks up.... well thats a big hunk of steel to fuck up. It's not like they can just grab another and start again.
by the time its done, the first part will be rusted again
Lmao! I wonder if they ever finished?
@@nwjones1 they should use some kind of oil
Like the Golden Gate Bridge literally the day they complete it they have to start it all over again
🤣🤣🤣🤣🤣🤣🤣
JAKOB
and after that, one of this guys say: "omg, look at the plan, it was 50 millimeters, not meters :D"
Come on! Jack up the spindle speed to about 5000 RPM. Run those tools in at about 500 inches/minute! I want to see chips flying to the ceiling!
Danny Criss ahh! American always in a hurry.
Danny Criss It would wobble terribly and break up the foundation of the factory.
Danny Criss Lol! If they did, we'd probably feel the vibrations here in the U.S.!
Danny Criss , you're fired!
Danny Criss At 5000 RPM at 4 feet diameter, thats more like 63,000 SFM. Might be a bit much for even diamond tooling to not instantly melt. ;)

you have it right . I did the same type of turning on large forgings . these people on here can't even figure out SFM . Gotta laugh. I would like to know how they even know the feed rate lol
What type of engine uses a crankshaft that weighs 3000 lbs, but only has a 3 inch stroke?
@@UncleBubbles94mhh... rock crusher?
The carriage is big enough for a man to ride on!
Awesome lathe!
Two operators. Five other people standing around, one filming. Still cheaper total labor than the US.
Cheaper quality too. You get what you don't pay for.
CaligulaClone so you thinking this big Fuckin piece of metal could be broken anytime 🙄
Under the kind of stresses it will endure? Yes.
my boss would say why so slow and why its not ready yet fak and why so many people standing
It costs 100 times more to live in the US.
Now this is a proper lathe!
Very entertaining how many people in the comments have suggestions as to what needs to be changed to improve this process.
Maybe all those people don't understand it; A facility with the scope and mechanical aptitude to transport, manipulate, and machine parts of this scale certainly have several engineers on the payroll. Do you actually believe that they overlooked determining the optimal angular speed or tooling selection of this lathe?
Welcome to the Internet, where people love to inflate their egos and pretend to be superior to others in a safe environment where said others and onlookers cannot know true identities and prove that the douchebag know-it-alls do not have the credentials to be making remarks.
***** OvoJeGovno You just got roasted, Ovo
Everybody's an expert! On the Internet, at least.
+Don Burd where are your videos on the topic?
+Don Burd exactly
+Don Burd Some how I thought you'd take that personally. I poked the bear anyway :-) youtube experts are all the same
I love seeing and watching old things no matter what it is reclaimed. I do this to old houses. Anywhere in US
I'd love to see a time-lapse of this.
I love HUGE machines!
As AvE would say... Let's turn this up to 11!
Make sure you double up on the condoms and have your mother on speed dial! Also safety squints!
this is the most skookum of choochers that has been let sit in its own shmoo for the past decade
We had a guy that thought like that at water saver, tore up a cutter that took a year to replace
Yeah, that guy gets paid like 12k a month to entertain, man I wish I could do the same. No wonder he's popping out kids in his late 30's.

that engineering is simply amazing
"Can you take off, another 50micron please..."
Great. Now my 9" seems really small. Lathe envy...
And the legend says it keeps turning to this day.
This humorous situation supplies the world in owns our country and will surpass our economy soon enough.
I haven't seen this model of lathe at Harbor Freight yet.

¡¡amazing!! 5 days later, some beautiful weights.
Boss is like “get a cut on, stop tickling it” customer needs it .
WOW... they *welded* open-end wrenches on each of the four jaws of the chuck so the bolts don't loosen....
Love to see how they mic that thing
agreed. I would like to know how the accurately measure something that large.
Frikkin lasers.
No music.
THANK YOU!
For a rough workpiece like this forging, I wonder how they center it on the faceplate and tailstock. What part of it do they measure to judge whether it's centered? I imagine if you're not careful, you might end up getting the end centered, but then have a dent near the middle that makes it impossible to get the finished diameter you need?
Set it in vee blocks on a horizontal boring mill. Sweep it with a stick and find center.
Just use a scale to Center with, that’s how I Center forgings
THE CLEANLINESS OF THE SHOP AND WORKERS IS A DIRECT RELATION TO THE QUALITY OF THE PRODUCT. ALL THE MATERIAL ON THE FLOOR IS NOT A SAFE OR QUALITY ENVIRONMENT. IF I WERE TO TAKE A TOUR I WOULDN'T BE IMPRESSED. THIS IS A HUGE PART TO MACHINE. GOOD LUCK. HOPE YOUR NEXT VIDEO SHOWS A CLEAN PROFESSIONAL MACHINE SHOP. JUS GIVING YOU SOME PROFESSIONAL ADVICE.
Oh my. Is this what it's come down to? Saturday night and here I am, alone, watching......whatever the hell this is.
Yup, and it is a week later and I am watching it, too.
Two years later, Saturday again and here I am...
3 months Lathe-r and here I am!
Sat 9 pm april 7 anyone else getting a life?lol
8th of August, Saturday, 10pm, hi
unreal what a human brain can design and create to make things such as these big shafts
That's the largest forging I have ever seen.

I'd love to work in a place like that!
Holy frig! That's incredible!
Man, this thing could turn really big pencils ... and make my neighbours jealous ... *G*
Turning the worlds largest paperweight. Proof of Chinese master skills.
Now turn it up to 3000 rpm and run as fast as you can
Just play it at 1000% speed.
try 12000 and then you'll be running it like an angle grinder. THEN you run
I knew I wanted a lathe for Christmas lol
Прикольно рожки приварены, чтобы кулаки не отпустились. Нанотехгологично.
Что то мало лайков для вашего канала, Матвеев
Чтоб никто откручивать не полез)
Да я на таких деталях микроны ловлю каждый день🤣
These lads do't work to a thou- They have to be spot on!! 🤣🤣🤣
Where did they find this thing?At the archeological digs?
It's like watching grass grow!
I feel like I just watched the slowmo guys' version of a lathe.
Safety glasses, safety glasses. What are safety glasses?
PLEASE GIVE THAT NIMROD A PAIR OF SAFETY GLASSES!!
He'd just use them to chock the wheels on the truck at the loading dock.
If anything goes wrong during that operation safety glasses aren't going to help, it will take your head off.
Its very amazing with the difficult work
Remeber to lift with your back in a quick jerking motion
That has GOT to take weeks to turn that forging to a final dimension! Makes you appreciate the precision needed in the forging process. Have to get it big enough to be able to turn a clleanup but not so big that it takes several passes.
camshaft for the 2017 prius . O.o
That looks very safe.
That is some big lathe , Imagine if you got it wrong , How much is that forging worth
HA, HA, HA,, that's a good one !!!
yea, it would cost more than just money, probably would cost you your job too
Nick Dunn or your life
alan manning what if it had a + - .001 tolerance i would quit
It's more Chinese crap, it will have a tolerance of +/- 1/2" on a good day.
Legend says the lathe is still turning today
Yeah work that shaft :3
thats a big solid shaft indeed
You know those bearings in that lathe are just begging for mercy
Really satisfying to watch ,
That is one puny lathe ...
Come to Praque, they have waaay larger ones
Your name isn't very czech
It's a hot job, hurry up, the truck will be here anytime soon. No you don't get overtime, you are lucky to have a job.
One guy working and five guys standing around.
+Barnekkid Signs of a good UNION shop!
+Barnekkid Welcome to north east china...
thats the ceo or president haha
+Barnekkid I'm sure because if that one guy fucks up.... well thats a big hunk of steel to fuck up. It's not like they can just grab another and start again.
CVR IV So what are you saying? The five guys are there to make sure the one guy doesn't screw up?
Now this IS a lathe!
he must be using Chuck Norris's toenail for The Cutting bit on that lathe.
hahaha
That's hilarious.
Nah, he's busy spinning it with his left hand.
ROFL!
THE MEME IS NOT YET DEAD!
Now them are the type of turning jobs that you want. Nice bit of sliding.
