Because it would be over constrained with a fixed center, you could be doing huge damage clamping the jaws unevenly. Great removal rate BTW. At work I was discussing milling vs. turning for hogging out big parts, because the Mazak VTC does not lend itself well to high removal rates, one of our big lathes will do it much quicker. Also it appears the chip thinning milling strategies do not work equally well on different machines.

I assume your finger nail is calibrated at a hardness lab after every trim. When I worked at a gas turbine overhaul company tool mark (or any surface marks for that matter) removal was extremely important. In aircraft engines the parts are highly stressed so they can be as light as possible and are therefore susceptable to crack formation at stress concentration points. Much time was spent with Cratex sticks smoothing out radii etc. Even grinding surfaces was problematic as certain materials are subject to grinding burns which can lead to crack initiation. These grinding burns are invisible to the naked eye and only show up when etched with nitric acid. The surface will look perfectly smooth but be burned and unacceptable for use. The parts you are making, while likely subjected to huge loads, are very heavily made and probably develop relatively low stresses in the material. While tool mark removal is good practice, it likely would make little difference on this part. Ken

"Let's be realistic, This thing did not break because of tool marks." "But all tool marks must be smoothed" obviously the new engineer covers all his bases. It looks pretty too! Shuffle blame from design to manufacturing. From manufacturing to maintenance, from maintenance back to design. Welcome to Boeing. Why did it FAIL. The design did not account for reasonable maintenance and manufacturing flaw allowances. "The reasonable test" And what is a reasonable engineer to do, cover those bases in design. DESIGN FAIL, PERIOD, or maybe a rough finish as well. Or lack of maintenance. Needed more grease as well. Probably needed the newer flux capacitors installed as well.

Скажите пожалуйста,а почему вы так резец установили ?
Что значит "вот так"
@@ChrisMajперевёрнута режущая часть ,где пластина на резце номер 1

@@ChrisMaj спасибо ,это видео все объясняет .Видимо я его не смотрел ,так как недавно на вашем канале.Очень интересный у Вас канал ,смотрю с удовольствием .Если честно ,я таких резцов ни разу ещё не видел ! Удачи Вам в развитии канала ! 🤝👍
...Конечно....такие станки.....А ты попробуй этот вал выточить на ДИП-500......
Part broke probably because the blank was not forged but machined from cylinder ... like this one.
Yeah, that might have had something to do with it, but you would not believe the things that they break at the steel mill.
Another failure point is grease fittings
Pretty hard to avoid tool marks on a THICC chunk of steel like this...
Who shovels out the 800kg of shavings?
The chip conveyor.
I assume your finger nail is calibrated at a hardness lab after every trim. When I worked at a gas turbine overhaul company tool mark (or any surface marks for that matter) removal was extremely important. In aircraft engines the parts are highly stressed so they can be as light as possible and are therefore susceptable to crack formation at stress concentration points. Much time was spent with Cratex sticks smoothing out radii etc. Even grinding surfaces was problematic as certain materials are subject to grinding burns which can lead to crack initiation. These grinding burns are invisible to the naked eye and only show up when etched with nitric acid. The surface will look perfectly smooth but be burned and unacceptable for use. The parts you are making, while likely subjected to huge loads, are very heavily made and probably develop relatively low stresses in the material. While tool mark removal is good practice, it likely would make little difference on this part. Ken
I believe that's rough turn rolls typically are finished ground to size.

Might have been bad quality steel that made the part snap, but toolmarks? NO!
Machine RPM
вы видите как делают в китае гвозди)))
А что же вы не всю последовательность операций показываете ?
Это будет двухчасовое видео.
PRO!!!
Kutos!
where is it cnc?? heavy work, but, why tis rubbish tool holder...
What are you talking about?
That poor, poor live center
That poor live center can easily handle 11000 lbs. That was nothing.

"Let's be realistic, This thing did not break because of tool marks." "But all tool marks must be smoothed" obviously the new engineer covers all his bases. It looks pretty too! Shuffle blame from design to manufacturing. From manufacturing to maintenance, from maintenance back to design. Welcome to Boeing. Why did it FAIL. The design did not account for reasonable maintenance and manufacturing flaw allowances. "The reasonable test" And what is a reasonable engineer to do, cover those bases in design. DESIGN FAIL, PERIOD, or maybe a rough finish as well. Or lack of maintenance. Needed more grease as well. Probably needed the newer flux capacitors installed as well.
So ein Unfug. Nach dem ersten Schruppvorgang mit der Bügelmessschraube zu messen. Da geht ein versierter Dreher mit dem Meßschieber dran.
This is a wast of material and plz y do edit the part wer u lift it we want to learn how to safely switch it
How is it a waste of material? Yeah, we could have used a forging, but it takes a long time to get them,and in repair, machine shop time is what we don't have cause everything is a HOT JOB
А почему без охлаждения?
When exactly do you decide to use coolant or not? There doesn't appear to be any difference between the times you are and when you aren't.
If I don't use it, it's mostly for video purposes.
