I regrind Kinefac dies once the threads wear out.

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.

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

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.

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.

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.

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

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 know nothing about this process, but I've never run a Swiss screw machine either. Cool! More stuff to learn.

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.

The "lets get rollin baby yeah" was on point.

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.

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.

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

Wow! Awesome video!

Fetty heads are amazing!

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?

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.

What's the smallest you can go with tr thread using this method?

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 love this guy 😂

THX for the heads up, but i learned about thread making in the mid 80ties.

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. Ya.. a users point of view.
