The King of METALS. INCONEL 718 🔱 8" hole thru 33" long.

[@userwl2850]

Next I have to turn this from 390mm to 360mm.

[@Pondimus_Maximus]

Boss: "I need you to bore an 8" hole in some inconel, 33" deep." Me: "I quit."

[@userwl2850]

Easy 😎😉

[@joedell71]

Subbed on the strengh of this video. Been watching your channel for a couple weeks now. Ive worked with Inconel before and this is impressive

[@pierremarcoux886]

You got me every time and never miss anyone !!! Keep going up good work !!!!

[@MakinSumthinFromNuthin]

The work you do is truly amazing David, that core probly weighed as much as my whole lathe!

[@mer9706]

Crazy stuff! It looked like the inco was doing a number on more than just the inserts too.

[@charliemclaughlin1042]

The lovely sound of inconel chips popping with to horrible sounds 👍👍👍👍👍

[@forrestgumpv9049]

WOW , now you are Master of King of METALS. I did not think that could be done. Even in annealed condition , 718 is a beast to machine. I'm impressed, Good Job, and BTW get a RAISE.

[@MaximumDistortion2]

0:30 i LOVE that sound of the chips as they are breaking.....btw keep making videos i like them

[@abengineering9954]

Brilliant job sir

[@horkinyorkin]

very interesting. thank you

[@thecorbies]

Great to see that proper British engineering is alive and well. Regards Mark in the UK

[@sukhwinderpanesar2242]

Amazing work out bro

[@bulletproofpepper2]

Wow. Thanks for sharing

[@izalman]

Always curious what use the bored out billet would be used for.. Most be something special being Inconel.

[@ИгорьСухов]

Нравится мне Ваш канал, смотрю с удовольствием. I like your channel, I look with pleasure.

[@grumpyg9350]

God I love the sound. 👍👍👍👏🏻🍻

[@-Dark-Side-]

I work for special metals. We use trepans tho. I've literally seen these as 39in 50ton ingots. I'm setting in their refinery now.. lol Btw nice video

[@johnbravo7542]

What are you making,a canon?

[@paulperrin2152]

When you change the worn inserts ,were do you restart the cut??,

[@MakinSumthinFromNuthin]

Awesome stuff!.....Ha!!....An INCH tape measure!! LOVE IT! ~ Richard

[@userwl2850]

Makin Sumthin From Nuthin I always try to work in inches... old school 😎

[@Donkusdelux]

I dare you to get a small piece of hardox 600 to try out >:)

[@nowayjerk8064]

i found something while i was just reading something called whisker-reinforced ceramic cutters that may be the deal for ya ,numbers like 8x stock removal compared to carbide in nickel-chrome . iv no clue but that sounded wort passin to ya . thanks for sharing

[@miguelcastaneda7236]

Noway Jerk ceremics like higher spindle speeds

[@tjo8673]

@@miguelcastaneda7236 And ceramics are extremely brittle and would blow up right away.

[@neilmchardy9061]

Have you ever had any jobs work harden whilst doing it? I’m curious because of some of the exotics you use

[@userwl2850]

Yes. The worst is 01 and D2 steels. Have to be very careful it always stays has to be cold. Any high heat and it becomes untouchable with carbide. 😲

[@johnstrange6799]

Holy smokes. I can't even imagine what that piece of stock costs.

[@Valient6]

John Strange about 4 grand

[@userwl2850]

Valient Six the core is from the middle. 😉

[@Valient6]

userwl2850 why get the core from so deep in if you werent making a sleeve as well? Btw i dint ask about the core sir.

[@missmymountain]

To use it to build a smaller rocket nozzle for free...of course.

[@mehmettemel8725]

It must be a challenge to stop the machine in time so far into the part before it destroys the cutting head,when inserts are worn.

[@userwl2850]

Mehmet Temel experience helps too.

[@joshmdmd]

Cutting heads are worth nothing compared to the material saved. Lots of companies used to set and forget this operation.

[@MR6.5]

Man, you machine some SERIOUS metal! What industry do you normally do work for that uses such large parts? Thanks for the video!

[@gj91471]

Oil and gas industry... Need heat proof material for HPHT applications

[@pearcemachineshop5200]

If your that pushed I could do one of them on me Bantam to help you out, as long as you give me a year or two to do it. Nice job, impressive as always. Alan.

[@Valient6]

Holy shit man! That is some serious machining. Are you doing work for ships?

[@theessexhunter1305]

if it is hard you have to be hard with it....nice going...Tim

[@scottlowe1304]

You sir, by the very definition, are a machinist! Just the cost of that material must be $$$$$

[@nectouxpierre4634]

I Always love watching your homemade trepanning. What is your feedrate ? Very nice work ! 😁 🤘

[@Valient6]

NECTOUX Pierre looks like 2 m /hr

[@irish-simon]

do you get to keep the core ? and what feed /speed were you running ? great video keep up the great work

[@jimmurphy6095]

I'll bet the chips are worth a good bit of cash.

[@alasdairmunro1953]

Neat!

[@1stooge782]

Ever find any thing

[@shawnmrfixitlee6478]

EPIC AWESOME !!

[@userwl2850]

ShawnMrFixitlee cheers Shawn. I subbed your channel.

[@stelios413]

That is one massive hunk of son of a bitch.

[@1stooge782]

All that work is nothing when you got the toys. Lucky

[@gerdhennig66]

It looks like stonetime. Wellcome 2018. Why did you post that ?? Boring !!
