7075 is some super tough stuff. Good for some aircraft components it's down side is that it's prone to intergranular corrosion (xray inspection) which limited it's life cycle.
I machine 7075-T651 virtually every day and for the last 30 plus years! I just love working with it. 2 points harder than P-20 tool steel too, keep up the good work!
I too am wondering what its use is. Since there are a few of them, and seemingly simple annular rings, perhaps they are spacers for an industrial axial compressor?
Toughness is defined as the ability to deform without breaking. I never heard anything about 7075 being particularly tough. Where do you get your information? The non-heat treatable aluminum alloys are more likely to bend than break
ether you were way to fast, thats what it looks like or there was almost no Selicium in there... Normaly you can machine that whit around 400-600m/min and make some big cuts like just put the whole insert in there ;D But you shuld get some negative tool holders...
Just get your feeds and speeds right and aluminum of any type is fun to work with on a lathe or CNC mill. I do it every day, mostly extruded and cast 6061-t6
Its hard to remember when your working on a project but sometimes you gotta remind yourself that everything is ugly before it's beautiful
I spent 9 years running 30" and 42" Bullards. I really appreciate big VTL!
I'm always surprised when a crude-looking forging cleans up so nicely.
Man 120 RPM has never looked so fast lol
Imagine a cruise ship propeller of 7 meters in diameter turning at 120 rpm at full speed...linear speed is ~44m/s at the edge, scary!
You certainly made a silk purse from a sow’s ear. Thanks for sharing.

Now I know the reason they call it “rough machining.”
I watch your videos with sound off and Listen to Wagner....wonderful compilation....best wishes, Paul
work of those who know the subject, congratulations!!!
So glad we ditched those crummy arse Hankook Jaws years ago and made a proper 4 yaw table to bolt to mine. Boring mill jaws are so much nicer.
Looks like it is dancing the Rhumba...😂😂😂
Awesome
Wonderfully machined... :)
I come here to read all the “experts” posts. Funny as hell.
7075 is the best Aluminium to machining, on a Lathe or to mill, my opinion.
Impossible to make it flat
I have to agree. I quite like it.
@@bingosunnoon9341 how so?
@@bingosunnoon9341 ,
häähhh, ... what?
7075 has some very interesting properties.... Was it T6 heat treated
You can tell by the size of the work piece that it is not.
Parko why does the cutter head always spray so much coolant at the back where it is not cutting?
That was forged with some crude machinery.
wonder what the part is for
wondering also
@@ypaulbrown Also wondering? Maybe he will tell us!

good!
Pretty much my day but mines a smaller vtl
I love machining 7075. I loath, hate, and despise FANUC controls.
They were a big improvement over existing machines when they first came out.
@@bingosunnoon9341 doesn't make me like them any better...
Pretty! ;)
Why is most of the coolant not on target?
👍👍👏🏻👏🏻
Danger table, do not touch.
I don't know where you are but it would be nice if you would give us the dimensions in inches as well as metrics.
Id rather machine 7xxx series aluminium than 2xxx series. It doesn't like to break the chip.
The operator not explaining the process along the way is disappointing. At least there's no ridiculous music.
I didn't have enough explanation. I'm sorry.

I don't like soft aluminum
All aluminum is soft. Hardness is defined by resistance to penetration. Aluminum scratches easily.
@@bingosunnoon9341 I turned aluminum many times softer than this one, it was terrible.
@@StanislavPacourek I'm sure it was

@@chrislobby7447 if you haven't met soft aluminum, that doesn't mean it isn't there.
Half of the coolant was wasted
Too slow 🐌...
