I know you metric guys have a hard time with inches, so I thought that might help. If you ever have a bigger one in your store, let me know, I'll be the first one to get it 😉
Hello,my name is Guilherme I really like your videos, I'm Brazilian, I work with cnc and you are an inspiration to me, keep teaching and encouraging us thank you very much. Sorry for my English but I don't know how to speak it. I used a translator to try to get this message across.
Don’t mock the inch, fractions are absolutes, base 12 is a pretty good mathematical system, ask a mathematician. More difficult no doubt than base 10. Engineering wise the very first standards were set by Joseph Whitworth in 1841 and he measured to one millionth of “a banana” and designed the most efficient threads in terms of clamp to applied torque, to that date. His measuring device could show the expansion of a metal bar by the heat from a finger, 140 plus years before everyday accuracy of “a thou”. True engineering genius. Remember too that with base 12 and fractions there’s no rounding errors commonplace in metric, the blight of pcb layouts.
The combination of "oh sh*t thats expensive" and "oh sh*t if i break it it gonna take 3 months to get spare material and we never hear from the customers again" also maybe "oh sh*t if i drop that thing we gonna need a new machine or workshop floor/crane" is quite gnarly yes. Only had 2,75 tons on the machine so far but that thing was stainless so price wise some muscles were clenching indeed :| Excellent job as usual there man!
Yeah, I've been watching Kurtis probably from the beginning, so I thought I'll use their banana ruler in my video. They gave me a few pointers with all that RUclips stuff, but I just don't have the time to spend on all the editing.
I'm curios the reason why you finished the center section diameter after the milling work? And on a different machine. Was there something special about that center section that I missed? Was it because the Hankook didn't have enough X travel to reach that section? Love your work. You are certainly making the most out of the Fanuc control. No CAM required! All the best, Tom
@@ChrisMaj Bummer. You had to use the old clunker to finish that nice arbor shaft. That old girl looks like she was rode hard and put away wet. Blue chips and chatter for days. Cheers, Tom
1:57 does that mean, that the center can hold 5 tons or that the part can weigh up to 5 tons when its a straight cylinder? what if one side weighs 4.9 tons and the other 100kg and the 4.9 tonms are on the center side?
Hey Chris. Have you noticed all of your recent videos have the audio shifted to the left side only? You might be using an editor template so this gets repeated. It has been this way for a couple of months now. Thanks!
How do you go about running such heavy parts? Seems kind of terrifying, what would you set your pressure and is there any tips you can give to roughing heavy materials? Currently at my shop we have a guy that will retire at the end of the year and he roughs huge heavy shafts. I want to learn how to deal with such big parts but they seem intimidating any tips?
The chuck and the tailstock are all manual, so kind of go by feel. Keep your jaws tight, or the piece might spin on you when taking big cuts. Don't drop it on your lathe.
Had to laugh at the beginning Chris. If the crane went haywire and dropped that piece of material it would splintered those 4 x 4's like they were toothpicks. I know , I know , CYA right?
Loved the video. Quick question, though. Do you have a 4-way tool post mounted to the existing toolpost without any support? Am I just not seeing that right?
Czemu zasłaniasz niektóre średnice na rysunkach? Jakiś własny patent firmy? Chciałbym zobaczyć jak coś takiego się montuje. Jeśli na czop wału coś jest osadzone ze wciskiem to jak to zrobić?
Bo chciałem tylko pokazać te które w tym czasie obrabiałem. Może uda mi się coś nagrać z montowania reszty rzeczy. Na ten wał nachodzi jeszcze większe koło, będzie nagrzane i później nałożone.
Really nice work. Could you please let me know how you prevent chuck jaw marks on the final piece because we struggle alot with marks upto. 5 mm deep when we tighten heavy pieces on CNC lathe. Your earliest response is highly appreciated.
0:38 as you can see, I have a center in my chuck, and most of the weight is resting on it. On the finish surface, I'll use brass or aluminum shims to prevent any jaw marks.
Wow that’s a big lump of steel, Chris am I reading the colour of the steel correctly?? Has it been case hardened? Or is that just the colour of the steel as it came to you? Also a shout out to Kurtis of CEE for sending you a banana ruler love it 😊😊 As always Chris just wonderful work that you do, I never got to play at stuff that big.
I think the forging company did some sort of heat treatment after roughing. Yeah, I bought one for CEE store just for fun. They did send me a few other things.
They keep changing the picture of what is mounted in the lathe? One minute it is a machined portion in the chuck and the next instant it is a not machined portion in the chuck. What are they trying to pull?

Hi Chris happy Sunday. Thank you for this new video of machining a huge axis of five tons probably intended for the navy or heavy industry? I saw that you put the banana ruler of Kurtis the Australian from the EEC on your piece, it's funny because I follow his videos like yours on You Tube, it's no coincidence.

@@ChrisMaj ok,, I often use it and mix cycles from the machine with the iso codes, it works fine, I can't backedit on fagor, so the thread cycle is easier to do on the machine and quick to edit , I often do rough and finish on mc and add threads cycle on the machine .. it is impossible to do something like that on Fagor,..fagor 8055 does everything in steps, otherwise you have to draw the contour for finish on the machine, it is difficult and takes a long time because it is an old control

A banana ruler, did Kurtis send you one, they are very accurate, good to see you using it for layout work. 8mm grooving tool working well too!

Always awesome to see the turning happening on those huge parts.
Almost as awesome as those blue chips are beautiful.
I love seeing the chips turn blue. Such a pretty and satisfying color.
That was one of the most stressful jobs in a long time. I don't know if it was the size or the price tag for the forgings ($70,000 for two pieces)
Yes. Both.
Nice work man. Those forgings are mint. What baffles me is the lack of scaling on the diameter tolerances.
Measure twice cut once, in your case it's magnified!
Nice job, from a non- machinist!!

Got a fix8 on order right now... when I saw the gear on floor I thought I was looking at my old workplace :)
Giving the live center a workout! Good to see the precision CEE Banana ruler measuring instrument.
I like the CEE Banana ruler jaja good one
The weight a relatively small center will carry is amazing.
Yeah, it looks a bit scary.

Is that a cutting edge engineering banana ruler?
Sure is.
Takes a large set to do that work. Amazed a small footprint machine can hold that weight.
I'm impressed that tail can withstand this, almost 5000 pounds shear force
Sometimes, I'm looking at it thinking what would happen if it broke.
You gotta love that kenametal tool mate 👍 great video and thanks for sharing 👍
Love the CEE banana ruller, had a great laugh =)).

It's not really my department, but I'll try to get more videos from that lathe.

Excellent job.
From the sound of it it needed bigger tool holders and tools but you make do with what you have.
1:57 does that mean, that the center can hold 5 tons or that the part can weigh up to 5 tons when its a straight cylinder? what if one side weighs 4.9 tons and the other 100kg and the 4.9 tonms are on the center side?
Good question. I think they just mean 11000lbs/ 5 tons between centers.
Great workdone💯
Hey Chris. Have you noticed all of your recent videos have the audio shifted to the left side only? You might be using an editor template so this gets repeated. It has been this way for a couple of months now. Thanks!
I have a question, will leaving a double radius in the corners reduce the concentration of stress and therefore make it stronger?
Dang, what was the finished weight in bananas?
Good video
I love the ruler lol
It's pretty accurate.
