Is the lump of wood? There to help balance the job or as some sort of harmonic dampener? Looks very lightly strapped on and can't really see the point of it. Anybody shed some light?
+Andrew Wilson Aha! Quote from Axel Fibro 2 years ago: +tom gorney The meaning of the wood should be to reduce vibration. The piece being machined is a hole tube with 20mm wall thicknes and most probably would act similar to a church bell, which would make the accurate machining a bit complicated.

Hi The runout will be because the workpiece is a forging that was made on the 10,000 tonne press in our Forge.. It's a solid piece rather than a tube :) EDIT, Someone has said that it's a tube rather than a solid bar, I'll bow to their superior knowledge as I actually work in the heavy foundry in the next section ;-)
I run a larger lathe with jobs that are 30 to 50 feet long with diameters anywhere from 16" to as large as 154" and the work piece can weigh as much as 300 ton. The jobs I work on have center holes on each end with 1 1/4" threaded holes to mount our drive plates to it. I'm assuming this is done the same way. When running your initial setup there is no indicating needed because it is a raw forging. If this piece gets a 2nd setup, we call a turn around. Run outs are corrected buy shimming the headstock center and grinding the center on the tailstock end of the job.
My safety people would send me home for two weeks without pay if I strapped anythinng like that to a workpiece! For harmonics, I have wound rubber air hose around tubes to dampen the vibrations, but that piece of wood could kill someone! No O.S.H.A. around here!
For the same reasoning most big industrial machine shops like this are in countries that have no such policies. The lawyers have fucked the great U.S.A. industry.
Right, it is not a counter weight like you knew. It is to reduce the vibration.
Nice lathe, biggest in the world, NO way.

its there so touch wood nothing goes wrong

What are you making with this massive machine and steel?
Seems like a lot of runout in the middle. If it's a tube, how thick is the wall?

Even steel gets morning wood.
What's with the piece of timber tied to the job?
a block of wood maybe 3 kilo's as a counterweight for a bar that weighs in at 15/20 metric tons ? :)
Big welded sectional pieces of pipe, but you need a long bed to turn it !
Looks to be running about an inch off center.
the lathe from part 02?
No it isn't.. I worked on ones much larger
Could it be a balancing weight? Just an idea.
Its how many feet lathe
Why the wood strapped to?
how in the heck do we indicate such a piece ?!

@@hotspringsautospa1707 that is correct.

Thanks
Our Shop only got a machine with 5 meters lenght :) and i hate to work on it :D
Este é um peso de aço para balanceamento,não é madeira.
Having seen some runaway workpieces careening off nearby machinery and workmates, I'd hate to see the failure modes on that thing.
Shortest video of the longest lathe in the world
Just wondering the same thing !!!
나무를 묶은 이유가 무언가
where is cutter bro
Could be or for chatter?
thats definitly not the biggest lathe in the world I worked on one with a 14ft chuck 55ft long and 4 saddles 2 back and 2 on the front bed
para qué tiene ese trozo de madera atado??
More runout than the diameter of most parts I make..

It could, but i doubt it ever gets up to those types of speeds being so large.
+Isaac Dahlvang Right? Can you imagine being so slow that you couldn't dodge a hunkawood flying at 7mph?
