Punch Tap / The new thread technology

When comparing the tool path of the EMUGE Punch Tap with the tool path of conventional taps or cold-forming taps, it shows that the path is approximately 15 times shorter for a thread M6 with a depth of thread of 15 mm. The result is a signifi cant time savings up to 75% in a threading cycle.

Amazing lack of information. Less "music" and more info would sell more taps.

[@cbbowness]

So glad they explained in so much detail how the average shop can use this technology to increase production. Oh and the only demo was on threads already cut. very helpful.

[@JaakkoF]

Threads that were already cut? If you go t 1:45, you see it tapping new holes.

[@ipadize]

​@@JaakkoF no thread was cut nontheless :P

[@adisharr]

Great demonstration! That's quite an interesting approach.

[@DothBeEthan]

This is awesome. How would this type of cycle be programmed?

[@randyb1890]

Bad demo.. At 1:23 it shows the tap withdrawing and leaving behind a fully threaded hole. If I understand this correctly it broaches two spiral grooves down the length of the hole then rotates 1/2 turn while feeding up at the thread pitch, forming the thread. It is then back in line with the clearance grooves and withdraws. This leaves 2 sections with thread and 2 sections with clearance grooves. So, what is the strength of these partial threads?

Wow,amazing tap!

[@shervindevich4255]

dose it work in the typical hex nut tapping?

[@ericbuzard349]

Is that much vertical load on the spindle good for machines? I feel like rotating workpiece like that can only spell bad news for the spindle.

[@robs4193]

Great concept! Now, to get the part designers to be ok with holes that have a helical channel... I could that such a thing not being a problem for blind holes, but through holes would present challenges, such as not being suitable for use on sealing surfaces, etc.

[@JaakkoF]

If you have threads in a sealing surface, you still need separarte seal to prevent the thread from seeping through. So I don't see the problem.

[@173roberto]

It is insane I want to see it in real action

[@ideasalerts1343]

What can be maximum diameter of application?

[@CNCSKILL]

Such as the taps on the video, I have not met!

[@ideasalerts1343]

thread forming diameter I am asking for

[@TheScott632]

need this in an M24 x 3.0 ASAP!!!!

[@chandermohanthakur5999]

amazing technology of today.

[@CNCSKILL]

Give answer! What isplzovat cycle necessary to cut the thread of this tap? Or it be programmed on the machine?

[@PisTTasha]

There is a special cycle in siemens sinumerik controller called punch tap , if you have that controller you can try it .

[@emugefrankentv]

A Siemens Punch Tap cycle is available. In general we have to support you using this technology, because several analysis and adjustments are necessary depending on your conditions.

[@mythai9593]

This video is 5yrs old and still not seen one, wonder why 🤔

[@JaakkoF]

Main use is in automotive etc industry where seconds count. The other is that the machine controllers need updates to be able to these, I believe Siemens was one of the first to adapt this technology in their controllers.

[@christophenanteau2730]

Très intéressant mais comment faire si nous n'avons pas une commande numérique siemens ?

[@kuei12]

I can only see this being used in specialized applications where thread strength does not matter. I cannot think of a single customer that we have that would allow a tapped hole with 2 helical slots running down the thread walls. If thread strength does not matter, why not just have a shorter thread depth? Also, programming this would be ugly. I think I will wait for the 5th generation tapping.

[@JaakkoF]

Programming this is easy: Select the pitch, depth and hit go. Your machine controller needs to understand this sort of operation, so if it doesn't, make a macro program that you can input the depth and pitch and it does everything by the numbers. No need to program multiple times.

[@liquerinfrnt]

very interesting idea, but seems like your have lots of burr problems dragging the teeth through the threads like that

[@JaakkoF]

It is returning the same way it got in, so no extra dragging on the threads.

[@btac6481]

what about for use on titanium

[@randyb1890]

Per article in Modern Machine Shop( Jan. 2019) magazine it only works in material no harder than aluminum and only from #8 to 5/16"

[@toddmckissick2931]

Awesome new tech but they missed a great opportunity! Turn the entry spiral counter clockwise, then roll/form the threads as it's backing out (still counter clockwise), then either pull back or continue rolling while still counter clockwise. No spindle direction changes would mean even faster operation. I don't see why the entry spiral direction would matter other than if it was reversed from the thread spiral, they could cross closer to perpendicular which would allow the roll forming to 'mush' the entry spiral back into a full thread without the entry spiral remaining.

[@toddmckissick2931]

Oh, and in case you're listening @emuge-franken , I'll take a set of english and metrics for aluminum if you use the idea. Beyond that, enjoy. :)

[@andrewmoore6108]

I'm having a hard time understanding how actual hell you could slam a tap into this hole, and then remove it without changing the spindle direction....

This is an example when a video producer thinks he's an engineer. Engineers deal in facts, not feel good music videos. More details, please.
