Careful, might have been a knock-off.
Better deal on Amazon, with free delivery, bought 2.

A fantastic CNC marvel without doubt, but I was using bigger manual lathes over 45 years ago until they de- industrialised the UK.
Yeah if a lathe doesn't have its own elevator it's nothing.
@@1pcfred And a wheelhouse on the carriage.
@@Pow3llMorgan a perpetual poker game too!
@@1pcfred
And a string attached to a bell when it comes to the end of a cut.
Exactly, I used to work on a large Cravern Lathe, way back, two overhead cranes used load me up, used to stand on the saddle most of the shift, nackering climbing up and down. I'm retired now, but i know the still have that Lathe, used to enjoy it though..
In the Number 2 Machine Shop at Bethlehem Steel at Sparrows Point, MD was a lathe 125-feet between centers. Finish cuts needed to be made at specific tidal times to avoid distorting the workpiece.
Wait what did tidal times change?
@@ricky107_ the workpiece would have lifted slightly off center, causing a dimensional anomaly ...
That's incredible. I've heard amazing things about that place. I wish it was still there. Seems like an age old story, places driving out industry.
damned commie MOON screwing up my BALANCING AGAIN
@@blackburn1111 With help from a neighbor, who knew about my mechanical abilities, and who was a big boss at one of the mills there, I went from a high school dropout to tool & die maker apprentice, roughing out and finishing explosive bolt sets, helping a small group machine thrust domes, and working on other contracts for the Apollo Moon project. When the NASA work came to an end, I worked at the Point for another few months until 12,000 engineers and machinists were paid off (me included). I never worked in that industry again, but what I learned there in three years was an enormous help in subsequent businesses.
My favorite Point story was one that I actually witnessed. A group of half a dozen guys were sent down to inspect a tunnel used to carry gas lines from the coke ovens to Baltimore City. We were equipped with respirators, HD flashlights, and two-way radios. Nobody had been in that tunnel since the end of WWII. we had only gone a few hundred feet when we came upon a makeshift table, four makeshift chairs, four poker hands had been dealt, and on the four chairs were the desiccated remains of the four poker players. Each of the men still carried ID and ring of tool checks. Apparently, the men all worked on graveyard shift, and every night, they would leave their machines to their helpers while they went underground to play cards. One night, there was a huge gas leak which probably killed the men instantly. The company reportedly placed the four on AWOL status and terminated them, not knowing the men had never left the job that fateful day.
Is it a big lathe, Yes. Largest? No way. Working in a factory years back, the lathe at the next work station had a 144" (12 foot) swing and a 50 foot attached bed plus a long, unattached sub bed. Across the aisle was a 'little' 84" swing, 25 foot long bed. There were larger in a different department making steam turbine rotors
A piddly 12 ft. Swing? We scraped those making room for 20 ft Swing.
@John James do you think he would sell it as is where it's at?
Mine's bigger than yours
I remember many years ago watching something on TV showing a huge nuclear reactor chamber (or something like that) being turned on a gigantic lathe. The original casting was 15-20 FEET in diameter, made this look like a watchmakers lathe.......
we had a Craven at folkes forge in kidderminster that was from chuck to tail stock 33 metres long. a swing of 96". it had 7 steady's and me "shoveling the swarf" great days of engineering. i weep when i see these great machines.
One of our customers has a Craven - every time i walk by it I think "wes Craven' and 'nightmare on elm street' lol. Its a beautiful machine and they just had spindle main bearings replaced. She runs like the day she was built! God Bless!
I did work in Todd Shipyard, in Seattle, WA. working on a very long Lathe was finishing turning the ship's rail shift, I love being a machinist.
so this is for a ships transmission???
@@vincentliuo Yes, the propeller goes on it.
USS America had a damaged drive line that occurred in the Atlantic during a rough crossing. It stayed in and the vibration continued for almost 20 years until it was decommissioned. How do ya remove and replace?
@@printzapper Many reasons cause vibration it needs rebalances or replacement, bearing in this drive shift, Send to dry Dock for the repair job.
@@vincentliuo This is a propeller shaft for the ship which they call a driving shaft.
"Mine is bigger than yours" is definitely applicable here
When I was a kid I worked in a shipyard and the lathe I used was much bigger. I had a seat on the carriage and went for a ride that often took a whole shift for 1 cut.
I worked in NDSM in Amsterdam where I was told that the largest lathe that they owned was reputed to be the largest in the world and the first time I saw it there were four men standing on the toolpost with room for more. I honestly could not believe it was a lathe at first until I witnessed a large marine crankshaft being turned. That was back in 1965 and sadly NDSM closed about twenty years or so after. The scale of the machinery in the large machine shop was like a giant fairy tale and I am so glad to have worked for them.
I worked on a 24" hollow spindle. The steady rest was out in the steelyard on a chain trolley. Manual API thread repair of tool-steel subs, casings, and drill rod. Had to stab the little door, and both sets of jaws. When I turned the tool steel I had to specially grind my tool into what was called a spoon. 20 rpm, feed-rate, min .060", 3/8 depth. Engaged cross feed and lateral feed simultaneously to hog off the end. The shaving came off glowing, then turned a nice blue, razor sharp. It would snake around my lathe and I kept an eye on it (among other things), ready to redirect if it with my broom handle if it got hung up.
Looking at the thumbnail, it looked more like someone was building a full-scale model of the Wave Motion Engine .
It might be the longest CURRENTLY operational Lathe, but there were many larger ones in the recent past.
yes on in victoria Australia make this look like a baby
Allis Chalmers had the world's largest lathe in Milwaukee, until it closed
It's just clickbait
Ho un ko
no
@@RJ1999x
Impressive setup. But there are larger ones still opreational. 30m length for turning reactors are still in use mid of germany.
I can't even imagine the foundry that produced the enormous blank for that job.
I worked on CNC Mills that make this look like a toy. 1 story underground and 2 story's above.
Did you work on the third floor 😳
In Newcastle when we had a Shipbuilding industry,there was a lathe for turning ships propeller shafts. It had operators on both ends,who sat on the carriages and were in communication with each other. “ That was a lathe”
Is that a lathe or a TBM ? 😂
thats the 42nd smallest lathe I've ever seen
@mackk123 you must be operating lathes than don't touch the ground because they would warp because of the earth hemisphere nature!!!
Ikuuuuuÿ bisous y nnnjsjjgya🎉😌😏🥰😌 0:37 🇮🇪@@berntinulkshredder
I ran a Craven lathe with 120” chuck all manual.
Looks like the tool holder wasn't secured tightly enough. It moved when the insert engaged.
Could have just been backlash or even flex from the massive amount of pressure on it.
Looks like the machines at Farrel Corporation in the late 70's.....except the one in the video is smaller.
We got a 130" X 37' Farrel. New Siemens 840d control. She's a sweetheart.
How big do you want your lathe?
'The tool carrousel has to be an actual carrousel.'
Plays Colonel Bogie when it chatters?
those are simply amazing!!! im no machinist i just enjoy watching those things at work for some unknown reason!!! i think maybe i should have at least dabbled as a hobby!! its just cool imo!!!
I could spend all day watching that huge lathe go to work.
See the tool holder move at 0:02 seconds, very professional for the biggest of big, big, biggest lathe in the world, ar!
It's still accurate to a tenth... Of a meter.
I work with wobbly machines and can do fits with .01mm tolerance - i guess im a magican.
If the tool moves while roughing it does not matter that much.
And even while finishing it can be compensated if you know what you are doing and you know your machine, thats why it takes at last 5 years to make a newbie into a *somewhat* decent turner.
Its suboptimal yes, but life is not butterflies and rainbows only.
@@billklatsch5058 Tell us some more precision tricks Bill, I am very intrigued by your machining norms...
The piece their repairing at 2:33 is said to be a crankshaft but appears almost identical to a camshaft with a offset lobe like one, there's no clamping surface to allow for it to set like a crankshaft in a journal.
Probably an eccentric for a mechanical forging press.
What most comment's fail to recognize is the change in CUTTING TOOLS ,,, end mills, Grinding Wheels, and turning along with coolants have made all the real changes that is where the technology is. A Lathe has been a Lathe for a Thousand Years.
Kind of a shaft which fits into Kardashian sisters
I can still hear MR1 Morenz "feeds and speeds" but it's in that slowed down deep voice like when you play a 45 on 33
Pfff. How about a 6 meter diameter chuck? (not vertical)
Solid!
Top KEK!
What I find most interesting is that forgings the size of those workpieces can be made without internal defects.
That's what i was thinking. I assume on a piece that size the tolerances are a bit looser than what I would expect too. I wonder how much that blank cost
You can pretty much be assured that when the final product has $100,000+ worth of machine time scheduled (OR MORE), on it, several pre-machining inspections have taken place. (X-ray, Magnetic particle, ultra-sonic, etc)
cám ơn bạn góp ý .
With a coupon , nice touch
Just Brings back good memories of workingWebster Bennetts and big lathes not CNC
I worked at Westinghouse in Sunnyvale, CA 1980's 1990's. and there was a huge manual lathe that size or larger there.
I wish i could post a picture of a large Betts lathe at a shipyard that has the contract to do the Nimitz class air craft carrier shafts - huge! twin carriages and we put CNC controls on it including dual servo through 50:1 apex gear heads that work together and zero out the backlash on the Z axis rack. This lathe will cut a class 3c thread and its swing is 17.5ft 150ft centers and about two stories tall. Because defense work - we are not allowed to publish pictures. God Bless and thank you for presenting this awesome lathe!
I was doingsimilar work. We had machinists worked around the clock at that time. It was very impressive for a younger me, fresh out of NTMA training facility and met the real world. It was almost 30 years ago but I still recall vividly everything.
@@vigormanh2980 this shop is very large - 24 round the clock support and now a 10 year backlog. They just purchased two Italian lathes (i'll edit later when i remember the names) - these are huge full CNC on delivery and required immense foundation peers and piles prior to their placement.
@@prestonburton8504 It great to have ton of works line up. Must be a busy machine shop. Now, back to the size of the CNC lathes or CNC turning centers, those are shown on this video are not very humongous. I wonder if you have ever seen the vertical lathes. I have worked on them for couple of years. Very impressive they were.
@@vigormanh2980 yes - the largest are specialized Bullard's made for the power industry that cut the forms used to make heat treated pipe, couplings, elbows and bell fittings. As of six years ago, they still used hydraulic stylus pens that edge follow large patterns that repeat the contour shape on the forms. These forms are then used as mandrels during forging process and before final heat treat (38RC but i've seen 48RC on treats) - very high pressure superheated steam in primary loops. We are waiting for them to finally decide to go CNC but union opposition as well as certification of process stops this. Actually, that is in texas and mexico plants. Some of our shipbuilding plants cut ship pistons on large cnc now - but the largest is an asquith manual 30ft table that was made in the 30s and i've actually worked on the one in newport news shipbuilding - hand made by them in early 1900s and is used to make propellers and parts of the shaft drive line including the final part that gets fitted into the hull. I dont know if its been converted to cnc yet.
little lathes made the bigger lathes, and the cranes so on so fort just as smaller blast furnaces make the largest blast furnaces .. crazy, you cannot make a large gear without the smaller gear being made first, try it..
U would have 2 Think LARGE in this Environment !!
Amazing !!
👍's UP...
Lijepo je raditi n'a takvim velikim strojevima,i sam sam radio 14 godina,na takvoj masini .
GE was operating lathes bigger than this in the 60s, they would make chips 3" wide and had a chuck that was at least 14 foot in diameter. Length was variable since they could put in track sections to make Length whatever they needed. The steel mills of Pennsylvania had even larger ones. Most were sold off when the mills closed.
I worked on a 16' Mesta lathe in Anaheim,Ca at the Ge apparatus service shop where they repaired turbine spindles. They had bid VTLs there also. Fun work.
The largest in Sch'dy LGM dept, 1960s (Bldg 16) was the 144" noted above. LSTG (Bldg 273) most likely had even larger but that wasn't the dept. where I worked then.
This is amazing !
A turbine center rotor that large that _HAS_ to hold the tightest possible concentricity and surface finish because of the high RPMs involved! Something to be marveled!
The camera's tripod is not sturdy, so the image is not very good. Please understand
Bin mit 38Jahren mit meiner Umschulung zum Dreher fertig geworden, niemals kommt man dann an so ein Werkstück!!! Nur als Video. Kurt
This was such a great video, I subscribed twice! Once for each time you felt it necessary to add the obnoxiously annoying "ding ding" [Subscribe] animation.
I have already suggested he should add more of those nice notifications in hes videos, preferably every 10 seconds with a louder bell and in the middle of the screen, just to make sure people don't forget to subscribe.
Only twice? I hit subscribe 3 times
When you gotta get the special catalogue to order inserts you know that it's good.
NIce, but the closeup cuts are disruptive and too short on the machining. Also, the white text pop ups are difficult to read since they didn’t have enough contrast with the background. Content was interesting, but the production was quite lackluster.
I do have to say its nice to see somebody take a cut instead of piddling around with these tiny stringy chips
Remember, all new machines were made on older machines, the accuracy comes from the operator
That's true. I worked as a lathe operator on conventional and CNC lathes a long time with parts up to 1000 kg. One mistake and a part worth a couple 1000€ is trash.
For the final product perhaps.
But machine tool accuracy is required for certain operations such as the flatness of turbine shaft flanges, straightness of gun barrel bores etc. These require accurate machine tools. The machine tool fitters are the ones who assemble the various machine pieces and adjust and fit the pieces to achieve this accuracy.
Does it also trepan?
That is some cool stuff.
Look at all the gravy. Sunday work
wow very big and heavy machines
“OMG, I made a mistake! Can we do it again?” LOL!
Way to go! White captioning on a white background! QWF?
How wonderful it must be to work on a lathe that has a tailstock that the operator rides on, and it has a guard rail as well.
the operator rides on the carriage, not the tailstock.
@@theturdcurd2382 I looked again. It's the tailstock. It's flat faced with a hydraulic ram with a center in it to support the part. The carriage is shown toward the end with it's rotary turret. That's different. Not what I'm talking about. He's riding what on other lathes would be called the tailstock, not the carriage.
Whatever, I worked on one, but you be you, I'm not gunna argue over this.
@@theturdcurd2382 Smart. The thing the man was riding on with the handrail had a flat face, large plunger that moved out the flat face. the center of the plunger had what appears to be s dead center in it that they show coming out and engaging the long shaft coming out of the chuck. The tailstock had no other tooling on it. In my machining world we call that a tail stock.
Later in the video they showed a turrent with various tools on it that would rotate and the tool would move off onto another part of it. That would be the carriage.
But what am I going to believe, right? You or my lying eyes?
Sorry, I don't believe you've ever come near one of those machines. I think you took a hasty look at best and made a hasty comment.
Were talking about 2 different videos then. Again, not gunna argue.
You haven't seen many big machine shops, have you?
That first piece of steel seems to be the ram of an IHC IQIP hydraulic impact hammer ? (could be Menck as well)
I'd like to see someone take this huge lathe and use it to make the tiniest thing it could possibly make.
sharpen a pencil with it
If its jaws can hold a 📍 as, a needle I will if I get or come close to one!!
الأيدي الماهِرة الرَّائعة تصنع المستحيل أيدٍ ماهرة .
Craven machine tools Manchester England,thats right England,made the most massive lathes and associated machines this planet has ever seen!! Look up there history and be in awe!!!
In a few shots it looks like they're making a huge copy of the Stanley Cup. Try lifting THAT over your head!
The lathe at Allis Chalmers had a 12' diameter headstock. The tailstock rode on rails.
Machine Tool Madness !
Oh yeah, I run parts like this at work. Sure, I do. About that size, give or take a few feet.
Imagine turning a giant shaft and scrapping the part on the final cut. 😫
In making only one of something so massive, it may be permissible to simply alter the dimensions of the mating part to match it.
Yes, a bloke at GEC committed suicide after taking too much off on the final cut.
Company won't even give you time to get your tool box, out of here!!!
@@galewinds7696 Good employers never punish for an honest mistake; after all that is how one learns.
Just don't make the same mistake twice!
All machinists stand in a few puddles, some deeper than others it's called experience.
These lathes could easily make some God-sized weed pipes.
I worked in a shipyard in my 20s, they had a lathe with a chuck over 15 ft in diameter, and even that was not the biggest.
In the world's largest lathe competition, this one doesn't even make the starting grid.
OLD IS GOLD 🎉
If I was forced to choose just one piece of equipment for my shop, I guess I could be satisfied w/ a 12' × 40' CNC Lathe.
I'd certainly have material size options.
Hard on neighbors in a mile radius, their lights'd dim & computers reset every time I fired it up. Uh, they'd get used to it...
"Gee, sorry Boss. I read the micrometer wrong and took off too much metal"
Harbour freight were out of that model so went for the bigger one instead !
😁😁😁😁😁👍👍👍
That wasn't the one of the sfafts for HMS Prince of Wales, perchance?
Good work
nice video but it's hard to tell what's actually going on. it's a bunch of short segments of different processes.
We have a Macintosh larger than that.....
My harbor freight lathe could turn that shaft as long as I oil it well before starting.
Bruh pick a font color different than the background the text is on smh
Here at Aperture we use the whole insert ... thats 60% more insert per insert!
❤❤❤❤❤
I would hate to be the one that screws up one of those big shafts.
We were making a large live center and screwed up the milled slot in it. So we just welded it up and milled it again. But yeah it's not a good thing to do. Still with metal you can get away with doing that. The foreman was all over the guy that screwed it up for a while. I doubt the customer was ever the wiser though.
I dunno if their as big as the ones we saw when we went down to the power stations workshop in the 80s
How many noticed the balance weight?
the title is absolutely mis-leading. Those machines are tiny compared to the equipment I worked with back in the day.
Questa è la mia gioia molto forte questa lavorazione.
Congratulations
First few clips are stolen from Seco (clearly) . Also sped up compared to the original
Just look at the WW1 and WW2 lathes makes those ginormous battleship and coastal guns.
It may be a large lathe but I doubt it's the largest.
imagine the size of the chuck key
When she's rolling chips the size of small shops bar stock and also doing a offset turn thats a big boy
you forgot Hüttenwerke Königsbronn
W Ostrówcu Świętokrzyskim stoi podobna. Niebawem zniknie… tak działa czas …
Definitely not the largest by a long shot. My partner and I designed and built larger ones for on site field machining at power plants. One of the lathes in our shop, we got from a shipyard in Maryland. 100' Ft between centers Giddings & Lewis. We found a old ass pic when disassembling the machine for transport. Apparently it was one of the lathes that machined the 66ft long barrels on the USS Missouri.
made in a wee fishing town in Arbroath Scotland
lots of giddings lewis fraser machines still being used
jig borers etc sadly company no longer there
Boggles the mind to think of the world's largest tools needed to make the world's largest lathe. And then.............
Not that difficult once you know how.
Very large machine tools are assembled from numerous smaller subassemblies which can be machined on much smaller machine tools.
Take a lathe bed for say 100+ feet of length for ship tail shafts and ship's gun barrels.
The lathe is assembled on a concrete block to give the bed stiffness. The bed guide ways are assembled from smaller length sections each of a length to suit the available machine tool size, say 16 feet long each.
Thus 10 of these 16 ft long section would be assembled into one long lathe bed.
Fitting these pieces together to permit machining of accurate gun barrel bores is an art unto itself, requiring much experience and trial+error work in the beginning.
Nowadays optical and laser alignment testing equipment makes that job much more predictable and easier.
Love the white text on white background 🙄
thank you
Dizem que essa navalha que é usada para cortar o aço é bem afiada eu não sei só ouvir falar
almost impossible to read the text description since it was small, white and only displayed for a couple of seconds. Voice description would have been much better.
!!
Don’t forget to remove the chuck key before starting 🤣
I got fired from a shop for making myself a buttplug.
Should have offered to make the supervisor one
Please share with you, hope you will have many good opportunities in the future
Those cams were out there 😳
