I would use old firehose from a local fire department or old cut straps to protect your rigging from sharp edges. Seen a guy drop a 25k lb rock crusher casting cause of it.
Machining castings is always fun , there is usually a ton of stock to remove to get to final size , Sometimes it's a balancing act to make sure there is plenty of material to remove on all machined surfaces . We used to have a VTL were I used to work but it never ran much and they sold it before I got to operate the bigger machines . I used to run alot of casting and weldments on my machine a 6 inch G&L Cnc horizontal boring mill . 3oo tons is nice but the hydraulic extrusion presses we built were 1800 to 4500 ton aluminum and brass presses .
How did you dial the second side of the piece work? You have to have some machined OD diameter from the first side to get some reference for machining an opposite side. I didn’t see that in your video!!!???
Another good video! Less than 24 hours since posting and already over 7,200 views! You forgot to mention that you changed from the larger Richards VBM to a smaller more modern machine. Is the Richards a retrofit machine?
@@jamespark_85machiningtv Almost looks like the crossfeed screws are still an Acme thread and not a ball screw. Good machine for roughing, but probably doesn't have the RPM's for finishing or smaller diameters.
It always boggles my mind how they used to do stuff like this this 200 years ago without Tungsten Carbide tools and a C.N.C. Sand castings wear the Toolsteel Tools out so fast. And yes I know it was done by hand on a BIG Boring machine, but, how did they make the Big Boring machine in the first place......mind boggled.
Don't take this the wrong way, but your machine has more chips laying around than a Lays factory.. Clean your workplace, a happy machine is a clean machine.

It is always a pleasure to see a professional work, and see the result of his work.
Thanks for sharing this James. It is always interesting and informative to see your work.
Nice to see you deburing.
You just trust the machine and the programer!!
All the best & thanks.👍🇬🇧
Bloody heavy anyway!
I was keen to see the outside machined as well.
Thanks for the vid.
Always love to see such big parts, you make chips bigger than some of my parts lol
Thank you for the content. It is great to see a wide range of product machined on this channel.
Great video, thanks for sharing
I just can't get enough of this shit. I love engineering, manufacturing, machining ,process and procedure improvement. !! Good stuff.
Nice machine, especially the bridge.

Хороший продукт. Молодцы, что выпилили.
I like the interesting jobs and work pieces you work with mate! You clearly have great skills 🤙🏻💪
Grandpa Machinist meanwhile is saying "back in my day, we used to lift these one handed"
I did stuff like that, Gravy job. That was a big one.

That cylinder can generate 300tons of force, its not the weight of the billet itself lol
I did wonder, when I saw the title.
I thought "it's pretty heavy, but, there's no way that's 300 tons."
Thanks, I was trying to get my brain around that and couldn't resolve and almost went into a embolism!
Always fake titel
300kg... is ok
" . . . trust the machine."
That was always the hardest part for me. Too many times the program was messed up when it hit the floor.
Is the part really running out round by 10mm? Doesnt seem like the machine can do eccentric cutting?
I love the amber monitor
How much conicity do you get on those very deep bore ?
The part has had all the forge scale ground off by the looks of it, how destructive to cutters is it?
How much weight did you cut off that original forging?
Fantástic Job !
Awesome
TEŞEKKÜRLER
Did you ever lose the fear of damaging something when lifting out finished product this heavy?
Why not mill the inside with a helical tool and get the whole thing done at once?
Превосходно!
The machinist is 50 feet tall and yes the billet is 300 tons. This video is in Texas
And when you're talking about a 100 ton hydraulic press, the press clearly weighs 100 tons. 🤔
@@Gameboygenius these piece is 10ton max
@@matejkumer615 I think you missed the point...
its a hydraulic cylinder, if the piston diameter is around 400mm and you have a oil pressure of 250 bar it will push a little over 300 tons.
That’s funny. So he’s talking about the piston strength not the billet weight?
People aren’t grasping the 300 ton part of the cylinder. It obviously has to do with the internal load pressure that generates 300 ton of force.
Yes in a hydraulic cylinder, if the piston diameter is around 400mm and you have a oil pressure of 250 bar it will push a little over 300 tons.
Damn what operating system does that thing use? Windows 3.1?

Yes, it is! It was a manual vertical lathe, but it was converted into a cnc lathe.

Great video! I also work on a CNC machine as an adjuster-programmer in Russia, only a turning group.
Thanks!
I am also CNC machinist India Chennai
I like BEER
Anytime you do your debuting with an angle grinder it's a good day!
Edit: deburring. Damn auto correct!
What about the rest of it?
more likely 3 tons us or metric. At ~8 ton/cub m, 300 tons are more than 30 cub.m or over 1000 cub.ft
Its a hydraulic cylinder, if the piston diameter is around 400mm and you have a oil pressure of 250 bar it will push a little over 300 tons.
It's designed to handle 300 tons of force, not weigh 300 tons, Stoyno.
What country is this?
300kg not 300 tons
What’s it for!!!!!

Machinist is the answer to most of your questions
Using canned cycles for an irregular shape casting is just wild.
After using google.
This is a cylinder body lifting weight of 300 tons.
300 Tons?
Surprised !
Or
300 kg ?
Pucker moment is when you can see and it starts machining. Please don’t crash!
3 ton

сдрассьти... чего , чего 300тонн?!?
Biggest air rifle pellet I've ever seen
3000000000000 Ton?
Toilet bowl for the giants, lol
Yes it is
I'd like to see the gun shooting that BB pellet!
Like your vidros and subscribed but that metal piece weights 300 tons really its an 747 Boeing
What a load a hit eh
10mm is 1km to james park :-)
That toilet weighed too much. Damn.
That's not looking like 300ton. 300ton is 38 cubic meter of steel, a cube with more than 3.3 meter per side
good
People here are saying that's more like 3 tons.
Big boys, big toys.. Impressive work.
300 or 30 ton ?
300 tons of force I think. 12" ID gets you that at about 5000 PSI which is plausible.

It is a cylinder that generates 300 tons of force.
No way in hell that is 300 tonne. Maybe 3 tonne

This piece is not more than 3 tons..
Рrobably 3000 tons, or even 300000?

Du verstehst das nicht.
300tons? Yeah sure!
That is a weird tape measure.
when you turn on the machine , you wonder what unemployment is currently paying if the gcode is wrong .
The lifting systems and size and shape of job prove that it should not be 300 tons.
Its not the weight of the part, its the force that hydraulic cylinder will be able to create once its finished
Really?300tons?🤔

You mean 300 kg
maybe 3 tonne not 300 tonne
3 ton grams
Eso no pesa 300 ton ni de coña!!
At the 5:33 mark it shows a 5 ton hook lifting a "300 ton cylinder body" unbelievable

@@aleksandrrr A ton is not a unit of force; en.wikipedia.org/wiki/Force#Units_of_measurement
If anything, a ton-force. The title is misleading.
@@MariuszCuch nitpicking, in everyday speech it is perfectly normal to use ton as force, even engineers do this.
Yeah and the dude nearly weights a hundred tons.
False for fools.
What a load garbage. I operate a 300ton digger and its huge. That billet is probably more like 30 tons
Yore speling is sumtimes terribel-
sorry
@@jamespark_85machiningtv You can tell by the spelling style in that comment, M F S was trying to make a funny joke. Not a criticism. 😉
Horrible casting...looks like part of the mold broke while placing the core within the mold...you probably have sand inclusions in the casting
