How to Form Threads In Less Than 1 Second

[@MPenzlin]

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

[@peterblack7400]

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.

[@gooblio]

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.

[@get_confrontational9508]

As someone that mainly runs screw machines this is very similar to a geometric diehead. That's the main way we run external threads

[@jakeman50]

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.

[@anup_david]

True that!

[@christianheidt5733]

Been using these since the 80's

[@rexmundi8154]

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.

[@kdenyer1]

Probably faster as well.😃

[@tsclly2377]

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).

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.

[@teambammotorsport7249]

Alright, pretty informative and comprehensive discussion, and demonstrations. The exploded view of the tool was cool as well.

[@bobmac9070]

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.

[@VidarXR]

Boom, I love it when the boss lets his crew shine!

[@flightmaster999]

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 wish you guys that make bolts would stamp an indent into the top dead center of the bolt heads .. so when the get stuck and has to be drilled out (as doing this, even way undersized can releave enough pressure to get them to release) one doesn't have to manually bang in a centering point.. like also having to grind of the head a bit first.. that can be impossible in some cases.

[@africanelectron751]

Installed a few mega brand rolling machines.... Incredible that this kind of tech can be put in a tool.

[@Dyna78]

It IS incredible, but I will say that after inspecting thousands of threads rolled by one of these heads vs. thousands of threads rolled by dedicated thread rolling machines, these tools are a compromise. Still likely a compromise most shops would find advantageous, but if you're running close-tolerance (allowing for plating, etc.) threads or SAE8879/UNJ threads where taper is controlled as well, I'd rather have the parts made on a dedicated thread rolling machine. As rigid as these tools are, they still often deflect, causing a significantly tapered thread (undersize at the beginning) or barrel-shape (undersize at beginning and end of threads, in-tolerance or oversize pitch diameter in the middle) when threading into a relief groove. Still a great tool, just not necessarily the best solution for all threads.

[@siffar]

Thanks for excellent video. That taper on pitch diameter towards shoulder though 😂. For aluminium try water soluble coolant

[@zbigniewmalczy8851]

Is there a difference between rolling thread and cutting thread? Does the grain structure changes and makes it better or worse?

[@dominictascone1471]

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.

[@chadc1982]

Similarly, is there an industry or application where rolled threads are prohibited?

[@dominictascone1471]

@@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.

[@kdenyer1]

Looks like thread is a bit truncated. Set the effective diameter on shadow graph then bring up rolling diameter till you get a good thread form. It would also be nice if you could explain more on profiles for plated parts which should be sharper than standard profiles.

[@kevinspacey5325]

Using a COMPARATOR isn't as accurate as pitch mic's or thread gages. . . . . Fail #1. Also platers will give to specs on the thicknesses of the coatings you use. If you can't read them and figure it out. . . . . . fail #2

[@Oohshtmfgtdmn]

Very knowledgeable.. I wish there was content on the dinosaur AF50s Producing a line up blank on these is so time consuming 🤷‍♀️

[@bigcat.3256]

Could you use gauge pins to set the ID or does the tool have some deflection or working in depending on material types?

[@dominictascone1471]

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.

[@dieSpinnt]

You know what? I don't believe you that "I found the way to make the perfect thread" ... ... because the side of the tool clearly reads: MADE IN GERMANY ... where I also found what you "found" in the manual of the tool. What a coincidence? Anyways, just technicalities. Greetings from Germany and thanks for the relaxed, calm and factual video:) Also: Are you serious? While the shown workflow is really impressive, dedicated screw producing tool machines work in the ballpark to spit out thousands of them per minute. We have machines here that cut, stamp, roll, press, de-burr, thread and polish composite plain bearings in one go to a thousands per minute (Modified and specialized Bihler machines). Those are "Titans" ... which of course have always the problems that they are inflexible (like the mythological ones), have long set-up times and may be pushed from the throne by a more flexible process (like the mythological ones, you get it) :)

[@VadimR4]

Thread forming also makes for a stronger thread.

[@tfoutfou21000]

How ? Can you details why ? My personal logic is confused about this one 😄

[@VadimR4]

@tfoutfou21000 cutting a thread introduces stresses, whereas forming is essentially cold forming the material making a stronger skin of the thread.

[@Norwegian_Bastard]

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

[@brandons9138]

Single pointing is WAY slower.

[@siffar]

Single point turning gets painfully slow as you increase the length of the thread.

[@brandons9138]

@@siffar To expand more on your point a little more. As the length of the thread gets longer you also have to deal with more part deflection. Single point threading is a high pressure process. There is a lot of tool contact even for a simple 60deg thread. The problem only gets worse with acme or square threads.

So I assume you make your own bolts to save time instead of relying on a huge inventory? I can't imagine this would be in any way cost effective. Great video btw.
