120T load heavy face lathe machine to process rotor shaft. 
Наука
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!
Stress relief before machining. Maybe?
wooooooow!!!
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.
Needle factory... 1,857,659 revolutions and 138 tons of shavings later then they start on the next one.
lol
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
🤣🤣🤣🤣🤣🤣🤣

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.
Could be risky reading a book, if a long shaving comes off it could curl up and go right through his body.
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.
5 days later... " Well, we got the scale off, now what?"
It's undersize
+Max Bowen fuck me I actually laughed out loud reading that
+Max Bowen just put a few layers of weld on it and start the turning again.
+david maher You would have to do a massive preheat first or the weld wouldn't take properly due to a lack of fusion depth.
+Mark Fryer also the metal structure would be very messy then and it might not even be possible to lathe it again
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.
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.
I haven't seen this model of lathe at Harbor Freight yet.

The carriage is big enough for a man to ride on!
Awesome lathe!
Man, this thing could turn really big pencils ... and make my neighbours jealous ... *G*
Turning the worlds largest paperweight. Proof of Chinese master skills.
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.
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 them are the type of turning jobs that you want. Nice bit of sliding.
That's something that when you see, you have all the right to exclaim "Holy Shit !!!"
I would definitely be going to Sam’s Club and picking up a few pallets of snickers because you’re going to be there for a while.
Although OSHA may seem like a pain in the ass, watching this video explains why it is needed. This looks like a real world class operation. I'd sure like to see the finished product.
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
Almost like watching a state highway crew repairing a road.
Very impressive. Pretty soon we can 3D-print this at home.
All those metal chips(swarf). There going to be made in to a Hyundai
thats south Korea, this is China. So it would be more like a Ayunduh
I was on a hwy between Richmond & Surrey ( near Vancouver Canada, ) , drove over a bridge that arcs over a another hwy, on the blind downhill side, was a ball of metal shavings , 1/2" wide strips, the ball was as big as a Volkswagen, sitting in the right hand lane.it would have sliced a motorcyclist into smithereens; it must have just blown off a fully loaded steel recycling truck, so I pulled over, ran back, it was easy to roll out of the way.
Just goes to show, anything can come up on a public hwy! Always be watching
now that is how you lathe a chunk of steel!
geeze.. one of those one part jobs no extra
thats a big solid shaft indeed
We are a very professional heavy duty copier from other countries . greetings from germany
'ah crap it's under spec now, let's get a new one and start over'
Very good work, I really like it
These comments are gold!
They're making a custom boring bar for their 'big' lathe.
Spettacolare, l'uomo non ha limite..
It must be a union shop. 5 men standing around watching a machine do their job for them...
They happen to be turning my new driveshaft, for my Suzuki Samurai...
More torque than a Honda
Tolerance plus or minus half an inch and we need it next week, so HURRY UP!
I would love to see the finished part, the radii at the change of dia must have been fun, especially as this is not a CNC lathe and the rads would have to be formed rather than generated. I'm also a bit confused as to why they are not using Carbide insert tooling, As with all emerging nations, they dont seem to pay too much time to health and safety, if one of those turnings hits you I guarantee you will know all about it. But having said all that they must know what they are doing or they wouldn't have taken the job on. Sad that we have lost the capacity to do this sort of work in the UK.
High speed steel is incredibly resilient. It could be they don't want to get this thing swinging @ 400 fpm until they get some of the bark off, and a little more in balance. Or, it could be that's just the way they've always done it? Hard to say.
Now THAT is a lathe lol
Apparently in order for it to work at least 9 people have to stare at it while it slowly turns
they're making an axle for that guy on the front tool post's '83 Honda Big Red. its OK though. They're on lunch break and making it from scraps.
That’s not a lathe, this is a lathe!
I don't think my wife would be okay with that one.
Is my sprocket ready yet? I'm paying alot for y'all to be standing around, logging countless hours in dress clothes! I need my socket for my X-Box!
chippin 6s love large capacity machining
how do you center that rough surface
carefully
good question rick
Using a giant lathe, obviously.
roughly?
这种上世纪80年代的技术，有什么稀罕的？
This 80th of last century's technology, what is rare?
It cannot be turned at a higher rpm until it has been turned round due to vibration from not being balanced.
Amazing !
Waow Security first its not your Goal! LOL
It’s hypnotising
Days without accidents : 1
Looks like a forging for a rotating field of a generator.
if the machine go all day long,issit the shaft going to be smaller like a tube?
Would love to see the micrometer they use to measure !
They would use a pi tape most likely
So why only showing the start of it and not all or at least what it looked liked finished?!?!?!
U done? Cool! Now Smoothen it
Ok, we've centered it... Time for 20,000 RPM!
PLEASE start wearing safety glass after you can say that you are professional
A rotor shaft for what? Hoisting anchor chains?That's (and sea water) the only thing I can think of that's heavy enough to distort a thing like that!
Nice
My video is lathe description.
And not a pair of safety glasses between them lol
LMAO, check out min 200 on this vid. The young man behind the 2 next to the Lathe doesen't want to be on this video. He's hiding his face
Nice
How do you 'size' something so BIG? And what with?
Safety glasses!
I have a feeling that this piece will not build upp heat so easily 🤔
Por más que se paren al lado del torno no va a hacer más producción, que bronca da cuando se te ponen al lado del torno como para decir "apurate dale más rápido" hay gente ignorante
omg waaw amezing
Too many people for no one to be standing next to the emergency shut off.
How do you think you can "emergency shut off" a 120 ton spinning load? If anybody gets too near, he/she is dead. Period.
is that the world's largest chuck ?
forget the lathe...i want to see the caliper they use to measure it...
im so glad the video is not shakie?
If you think the lathes is big, you should see the micrometer used to measure that shaft! Wow, machine porn!
Thanks
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. ;)
they're making an axle for that guy on the front tool post's '83 Honda Big Red. its OK though. They're on lunch break and making it from scraps.
and after that, one of this guys say: "omg, look at the plan, it was 50 millimeters, not meters :D"
"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... If he finds out that we could have finished this in a week... I can't even imagine what he's going to do to me... Maybe another "accident" like what happend with Liang Jii last year when he screwed up? I'm still having nightmares from cleaning the 12000t Press of his remains."
Good one

+DOOMGUY RUclips black hole
+DOOMGUY Hi,
Don’t know but it’s pretty impressive right?
And this is called learning even if we never chose this topic!
Hope against hope here, can anyone tell me what this gargantuan piece of steel getting turned might have once been a part of?
+mrbluenun Its not so much what it was once a part of, more what it will soon be a part of, which given they didnt provide the information, we can only speculate that it maybe some sort of drive shaft or rotor shaft in a large machine.
+DOOMGUY Top quality knives are forged by hand. The steel being worked here was also forged.
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
GE motor shop hete in richmond had an armature lathe , the end stocks were mounted on RR track, big azz motor
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.
+Robert Palmore "its not the size of the hammer, its the nail youre throwing it at"
Hello there, and welcome to Clickspring. Today we're going to be making a new tool for the shop: A 10,000 mm reamer.
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.
pragmax underrated comment
I’ve left the work just short of the line to allow for a bit of hand finishing.
@@pragmax I can hear his voice
Abom79:- "120T you say....Hmm Hold my Beer"
If this job was being done at a U.S. Naval Shipyard, the chips would be coming off looking like coil-springs on your automobile.
Frank
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...
franksalterego Also it wouldnt be made out of this crappy pot metal
thegenrl well then…lets send your job over seas as well...
thegenrl Instead of trying to get a job that good you're perfectly willing to pull everyone else down to your sad as fuck existence
thegenrl I don't believe a word you said lol
it must be a pain it the ass to center a 120 ton shaft in that lathe

Hard top be sure to whom that was directed. There are many levels and types of humor. Humor this simplistic works best if there aren't glaring factual problems to distract from the "joke".
If it fits, it ships!
This is just like when you pass a construction zone on the road. Some weird machine doing some weird thing and 5 or 6 motionless guys staring at it.
+wowforreeel Those are the safety spotters.
+wowforreeel hahahahahaha!!!!..you must of went by the road department crew. they got a backhoe running with the operator in it looking down into a hole in the ground, 5 maybe 6 guys looking down at same hole and 1 person with a shovel actually working. watch them till they leave and only the one with the shovel will have worked. guess it takes that many to tell the one how to dig a hole or make sure he's doing it right. road workers are gonna get fired when someone comes out with a kickstand for the shovels....hahahahaha...im just picking on state hwy workers...they really do work hard..*cough, cough not really cough*....friend of mine worked them making 13$ hr and quit cuz it got to hot standing there holding a slow/ stop sign.
+frances divine, I had never thought that what you describe above in your country is also the same work method in Holland, they do it on the same way.
exactly.....
+PGspeed88 i been in machine shop for 40 yrs hate cnc with long cut time. rather do manual work any day
I wonder how much this lathe is at Harbor Freight with my 20% off coupon?
They only offer it on the website, you have to wait for drop shipment from China, and they don't know when the stock will be ready. But you can place the order now and in 8-12 months...
How high are they when they drop it?????
forget trying to order it from china. itll take at least a year to consider even looking at your order,then maybe 2 years to ship it. it would be faster to make your own by buying scrap at the nearest scrap yard.
Andrew Phillips ARE YOU SERIOUS?! This isn't something that you can set up in a garage-!!
...and the electricity to run this thing would cost you a FORTUNE!!!
good one
suddenly my lathe feels very inadequate XD
Mr3wheeledbike It makes all our lathes feel very inadequate but I'm told it's not the size but what you do with it. ahem.... :)
ptonpc common way to shift focus :)
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.
Mr3wheeledbike How about your shaft?
Mr3wheeledbike At time size will not matter its what is in your head that counts Big Lathe cheers Bro .
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.
Excellent remarks!
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!
= profit
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.
If it falls off, they'd better have their steel capped shoes on!
Jack Frost pretty sure it would dent the steel
and the safety goggles everybody and their brother are bragging about...
@@Ms.Nightshade ...THAT'S FOR DAM SURE-!!!
It's a nice job to have but my back is starting to hurt after lifting those castings into the chuck.

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?

Chuck Norris has one of these, a bit bigger though. Grinds his coffee in the morning.
Thinking about getting one of these for my garage, I got a tiny little jewelers lathe right now and I think that skipping all the medium sized ones will be the right course of action.
