The tool is made by LMT / Fette. Only 10km away from my hometown in Germany.
One of my best friends gave me one of these rollers about 40 years ago, when he was working on the machine which grinds these rollers.
He is still in this company for more than 40 years now.
cheers
It's hard to beat German engineering.
Haha, the internet is such a strange place. I used to work at LMT Tools. An now someone on the internet wrote that he's also just living 10 km near by!
Maybe your friend would know, is it possible to by a few thread rolling dyes for gauge 14 UNF thread (used by bicycle spokes)? Not the round ones like in this head but blocks (for the sliding heads)?
@@davorinrusevljan6440
Now he is working in another devision, but I can ask him nevertheless.
He will ask his company tomorrow
Not only are these guys all top tier skill wise, they also have the personality to entertain.
Thank you!
@@donniehinske but they dont do a apprenticeship like a real tradesperson does all they do is production runs,, a capstan operator done the same back in the 60`s and they cant work on multi skilled machines they only train on one style for ten years then they might change over
@@gazzzza Donnie in particular worked for his dads shop didn’t he? Where are you coming up with the idea these people didn’t do any form of apprenticeship
You missed a couple alrights on your counter mid way through. Where's the QC
Not sure of their QC process for their videos.. They seem to miss little details in every video.
Mathew Mcconaughey only allows the counter to go up so high. It’s not in our control
@@donniehinske copyright infringement? I get it 😂
@@donniehinske thought perhaps your custom macro counter needing some tweaking.
Within tolerance I guess?
Keep On Rollin...' from the Fette guys, good job Titans
Nice video! It’s interesting that thread rolling/ forming is neither additive or subtractive machining. I would be interested in seeing a video on hole burnishing as well. Thanks for the good content!
Now that SIR is a fabulous idea!
Used one of these Fette heads to roll up to ½"UNF ~300mm long out of 316 stainless...great tool, super consistent for long runs. Very strong durable threads. The challenge rolling at that length was keeping the thread dia's parallel.
I'm a former tool and die maker and high school machine shop instructor. It's reassuring to know there's a healthy herd of young bucks absolutely kicking it these days.
We have to bring manufacturing back home if we're going to survive. . . . .
Very well done video. You are starting to slow down just enough for us old Guys to get it. No really, all kidding aside “Well done Boom”
Thank you! I do talk fast lol it’s not my fault tho. My 3 older sisters never gave me much time to chime in growing up 😂
I first started doing thread rolling on a Kinefac machine about 40 years ago. We were roll forming a worm gear and a thread on a motor armature. I think roll forming has been around for over a century and some. The technology has improved though.
I was a service tech for kinefac for 47 years
I regrind Kinefac dies once the threads wear out.
Excellent! What a great combination of education and humor. If presentations like this don't encourage youngsters in shop class to become machinists, nothing will. 👏👏👏
A bit manic although
Donny, you're in your element.
Back in like 1984 I ran and old Brown and Sharpe screw machine with a threading head on it, cuts threads but same principal to reset. It was reset by air pressure. If you look at an old book on screw machines from the 1950’s or 60’s I think most cnc lathe machinists would be surprised at how advanced the processes were. Advances in cutting tools and spindle speed aside, most average complexity parts could be made just as efficiently once the "programming" was done. I’m sure that old B&S is probably still churning out parts in China today.
Probably faster as well.😃
With short run, this still may be the yay to go, especially when running the 'problem' types of stock.. Aren't the older more manual machines more adapt to different types of coolant (oil based)? ...and for non standard thread (locking artillery type).
i think Donnie is one of the best Titans. somehow his videos make me laugh, he know what he talking about and his style of presentation just work for me. Keep it up man .
I sold Fette Thread rolling heads for CNC Machines. Operator s couldn’t believe how fast threads are formed. So much faster than single pointing. And a rolled thread is so much stronger than a cut thread. Not to mention the savings having to only use bar stock at pitch diameter.
I have 0 experience with any kind of CNC but I'm addicted to the videos on this channel
Great.
Best video I have ever seen about our products.
Good job from the team and presenter.
Thanks for that.
Best regards from Mario - Trainer and Senior Application Engineer LMT TOOLS / LMT FETTE Rolling Systems, Germany
As someone that mainly runs screw machines this is very similar to a geometric diehead. That's the main way we run external threads
We just keep on rollin, baby!
Are you ready? Are you ready? Are you ready?
Now move in, now move out, threads in and threads out
Back up, back up, tell me what ya gonna do now
Coolant in, now Tool out, cycle on, now lights out
Back up, back up, tell me what ya gonna do now !!
Man thats one sleek tool! And again excellent edition and information right there, just on fleek guys!
Thank you Donnie!! Best part of waking up is Titans in your cup.
50 years ago I had a summer job in a small engineering works and I thought the cam operated automatic lathes were amazing, this is like from another planet.
You see Limp Bizkit was 25 y ahead of his time ....ROLLING ROLLING ROLLING ...lol
Grtz from the netherlands Johny geerts
Best instructional video I’ve ever seen on Titan. A welcome change back from machine tool and tool ads.
a must view for all DIY hobbyist like me. Awesome !
Another great video from the man the myth the legend!
as a Kinefac tech we would always say the PD is boss ("V" thread), the rolled OD is a function of the blank dia./material type /class of thread.
True that!
this is actually seriously wicked. Love all your videos, really inspires someone to take up engineering. These machines are an absolute dream to watch work.
Donnie, You are very good at making these videos...I am impressed. Great Job!!
I use to work in a shop that did a lot of thread rolling, but they were large machines with does roughly 8 inches in diameter. They were for rolling large bars of stock that sometimes would get thread ground for finishing. Other threads like acme or standard v would be finished after rolling
This guy's enthusiasm is infectious!
Thread rolling is the cat's meow or the lion's roar!
I love it!
we used to and still do thread roll it's a really old and i learned it 40 years back :) it's a great way of forming a thread and much more economicly viable than cutting as wear to tools is very very marginal
The "lets get rollin baby yeah" was on point.
Alright, pretty informative and comprehensive discussion, and demonstrations. The exploded view of the tool was cool as well.
Donnie makes these videos great to watch. Expertise combined with humor 👌🏼
Fetty heads are amazing!
Been using these since the 80's
DONNIE IS AWESOME! He's a pro but also funny and great on camera. Keep this dude! BOOM.
Installed a few mega brand rolling machines.... Incredible that this kind of tech can be put in a tool.
Boom, I love it when the boss lets his crew shine!
set your rollers to the minor dia with a pin. then adjust your pre roll for safety. also offsets to your pre roll dia are 1-3 ratio to the major dia.
exactly, we just use a sample thread. Gets you very close and saves time.
Passerby here...
This shit is why I love the fact that The Internet exists.
Thanks! Better than TV.
I know nothing about this process, but I've never run a Swiss screw machine either. Cool! More stuff to learn.
Great Video fantastic enthusiasm and energy. The speed of speaking is just a little fast for me…the balance between enthusiasm and imparting information is a a difficult one to get perfect. Enthusiasm 10/10 information 10 /10 did I pick everything up 7/10 Amacf
Another great video Donnie!
Thanks Ma!
Enjoyed your vid. Perfect balance of technical detail, light hearted jokes and cool machines
Love the 'alright' counter
I used these heads on screw machines 40 years ago, I'm not sure if the one shown works the same way, because the ones I used snapped back to ready, they didn't need to be reset, but they were cutters, not rollers.
These heads are cool used them 40 years ago 😂
Great performance and economic of material 👏
Wow! Awesome video!
Yeah Donnie, you got some skills man!
And you'd be a good bloke to work with too.
It's interesting to know that for some grades of bolts/nuts, you are not allowed to machine the threads, they must be formed to meet specification. Because cold formed threads are more resistant than machined threads, there are situations where you simply cannot just machine a bolt because you don't have any in stock. Sometimes you need the real thing (cold formed threads) and using machined bolts will just not do. Heck, it can even be pretty dangerous to use a machined bolt in lieu of a cold formed thread, such as on a lifting device, scaffolding, etc.
I study engineering at university and were were just covering this exact topic about how cold rolled material and percent cold work impacts mechanical properties and I went to the comments looking for specifically a comment about how the process actually creates stronger threads. Thank you for not disappointing!
@@phantomforce1332 *I study engineering in my parent's basement and we were just covering this exact topic about how cold rolled material and my pet squirrel and I love macaroni and cheese and I once seen aboob on cinna max. ...* If something is designed with a brain and not a com pyuu tater you can skip all this junk engineering and get back to making cool stuff like we used to. Stuff that WORKED, stuff that LASTED, and stuff that will (STILL) be around when the digital garbage comes back a dozen times as a Hyundai!
@@bitshtannicajohnson6957 What a silly comment.
Bike spokes are a commonly rolled thread - just to show it doesn't have to be all high end aerospace or deep in an engine.
@@malcolmbagley7068 Just about all the bolts in hardware stores are rolled, aren't they? Just not on a lathe.
Great job.
Amazing. I'm in love with this.
What's the max length you can roll ? That's one of the limitations with sliding head machines as your limiting factor will be guide bush supporting the material.
Thread whirling on the other hand that will turn and cut the thread maybe a better option. Hope you do a vid on that next. Man the driven tooling is expensive for these machines.
You can roll as long as your part can fit through your roller. It also has to retract which is the same limitation as thread whirling for the most part
@@donniehinske Very true
i guess it depends on your roller-tool. I am pretty sure there some with a through-hole in the middle on the market, or working similar to a knurl tool, which is basicly the same process
@liammahoney7649 The tool has a through hole for the workpiece to pass through, so practically the thread length will be limited by the machine not the tool.
We've roll 1.5 meters long parts not so long ago so quite long
😂… engagingly informative… & FUNNY!
Good job!…KUDOS!
great video keep it up
god damn !!! nice editing guys !!!!!!
I like this guys energy, I feel like he could do "3 days of work" in 6 hours
very good presenter!
great job!
Woah bud that intro was sick 😂
THX for the heads up, but i learned about thread making in the mid 80ties.
If CNC manufacturing was a MTV show lmaoo
고마에서 땝기술 발전을 귀하의 노력에 감사드립니다
Alright!
@genswiss1 thanks!
Hola. Yo trabajo también cnc Tornos DT 26 .en Rusia 👋
LOL, you missed an "all right" at 5;47! Great tutorial!
Do you have to adjust the tools
Position in Z and the speed it feeds in at carefully to prevent the body of the tool hitting the larger diameter? If you need to control the length of the thread, is this just done by tweaking the Z feed so that the tool pops open at the right point? Trial and error?
how much coolant preassure does it need to work properly?
100 psi
Thanks for excellent video.
That taper on pitch diameter towards shoulder though 😂. For aluminium try water soluble coolant
We have one of these and they are awesome. We ended up not being able to use them as they won't roll threads over 45c rockwell. If anyone is interested we have it for sale. Retails for over $3K with dies.
Hmm, what dies do you have with it?
It is so cool! I wish i have one
Epico!!!
Could you use gauge pins to set the ID or does the tool have some deflection or working in depending on material types?
Typically I would set the rolls to a gauge pin having the minor diameter of the thread. You can also use a tap or even a bolt with the correct thread size.
I think that machine might need a few more coolant nozzles..... 🤣🤣👍👍
I love this guy 😂
Friends, sorry for the PR. Your support is greatly needed. At least just watch and rate the content. Thank you
Good stuff miducs
one of th eonly things i could think of being a downside is that you need a seperate tool for each diameter. or maybe you can take it apart and adjust it some way? there SPT has a better diversity, but require a lot more attention and the tool wears out much much quicker, or breaks, as it has minimal surface area and streangth, the rollers are a whole order or maybe two of magnitude larger than a point on a 60deg. threading insert. awsome looking and working tool. love it
I wish they would do more videos of the work they do everyday without the presentation and constant commercials for the tools.. lol these machines are crazy awesome nowadays
Can you show a slo-mo of milling the hex head on the bolt at 7:50? That looked like magic...
is there like a hand tool that makes rolled threads like using a die? or is there a way to roll internal threads?
Great video, Q. are rolled threads good for high torque applications like combustion engine head studs of main cap bolts?
yes they are
Limp Bizkit in the 90's! 🤣
What's the smallest you can go with tr thread using this method?
Could one of these be created to allow a pass through of tubing to do a large pitch the full length of a tube? Say a .625 tube with a .320 pitch grooved to a depth of .049 ?
All right!! ..... sorry couldn't resist. 😁
Alright
That was pretty cool
we use one of these were i work but have to manually reset it. we run it with coolant in a turret lathe. Any suggestions on auto resetting it since im thinking we wont be able too with the coolant since it gets ran during the threading process already.
Set up a rod somewhere that does it while the turret index’s. Best way to do it
@@donniehinske i was trying to avoid that, mainly cause im a coward and scared of crashing but it would be the way to do it dang it, ill look into it haha
@@tugyjones6690 you arent a coward dude you are a BEAST! also yes it terrifies the sh*t out of me as well. There are a few different attachments you can buy that will make the impact smoother so look into that for sure
Coolant on a turret lathe can be plumbed from a different station. Then you just index to that station, fire coolant to close, and continue with your cycle.
@@dominictascone1471 i was thinking if i could get away with something like that or the bar, got options and thats all i need to start figuring it out, thanks for the ideas.
Is there a difference between rolling thread and cutting thread? Does the grain structure changes and makes it better or worse?
Cutting disrupts the grain structure, cut threads tend to shear or fatigue sooner. Rolled threads compress the grain structure adding strength to the surface of the thread preventing failure/fatigue.
Similarly, is there an industry or application where rolled threads are prohibited?
@@chadc1982 In certain medical components and food processing equipment, because at the crest of the thread there is a chance of machine lubricants or debris getting trapped in the material. This can cause infection if installed into the body - ie. bone screws.
@@dominictascone1471 Thank you. Good to know.
@@chadc1982 yes - aviation
If you rolled a thread out of a memory metal, installed it, then heated it, would it work as a permanent fastener, or security screw or bolt?
Do you have a video on the station that cut the hex on the round stock?
Yes! Look up our video on polygonal turning!!!
Thank you I never seen it before. Nice video
Alright
did my first rolled thread today, on a 2mm bicycle spoke
So a Coventry die that rolls instead of cuts? Nice as usual, thanks.
How is the head of the screw formed? (Phillips, Tx, Roberts/square, etc)
Thanks!
Oh my lord, that american aluminium had me in tears ^^
I need that for 5/8 axle please advise us how to acquire this machine for my cnc lathe machine
