Test rolling of the Tesker Model 740 2-die thread roller. The 740 can roll up to 12" diameter parts using 340,000 lbs of rolling force. Video shows some initial setup steps, followed by the rolling of a 4.5" X 1.5 TPI single start acme in 1045 CDS. Video also briefly shows the included bar handling system provided for this customer.

Yes, it is a pretty versatile operation. You are correct, no cutting here, just deforming/rearranging the metal to form the threads. We make machines that can roll threads on a 24" diameter blank.

@TeskerMFG 11 лет назад

This stock started out somewhere in-between the major and minor diameters of the desired thread. Sizing for this type of thread is usually focused on the pitch diameter. For the same diameter blank, decreasing the pitch diameter will increase the major. The part typically grows both in diameter and length.

That's interesting using a roller for support. I used to set up and run an old Reed B-112, and it had a carbide, flat blade for a support. My employer is currently looking for a thread rolling machine, I will relay your engineering excellence to them.

Sick forces involved..

Outstanding video! Awesome machine!

I would imagine that the bar that is being formed would also grow in length. Also, the threads would be a lot stronger being that they are being in a way forged instead of being cut.

What kind of Material are them Rollers made of?

@Mcbleh 11 лет назад

Is the material growth calculated to achieve major diameter or are they full form rollers meaning the bar stock will lengthen only?

@stillbashingmetal 11 лет назад

I didn't know thread rolling could be achieved in diameter sizes and forms this big. Will it make larger sizes? No metal is being cut/machined, right? It's being squashed/ deformed into the thread shape. Impressive. Thanks for posting

How to adjust thread line ? Used By server? Thank you!

i need to know where this is done as i need this doing to my machine i need a revese thread for my gang saw (multi rip saw)

So this is how minature Oompa Loompas made my ARP Cylinder head bolts!

@syamprasada.p.9841 10 лет назад

Similar to cold rolling/forming? What about the mechanical strengths, grain structure and geometrical accuracy?

@TeskerMFG 10 лет назад

This page shows some technical details on the thread rolling process: tesker.com/thread-rolling-process.html

@KiwiKiller88 9 лет назад

its stronger than cut threads.

@Travisfromoregon 9 лет назад

yes please !!

SIR, MACHINE OPERATION IS EXCELENT, I NEED A MACHINE TO MAKE 8 MM PITCH FOR DIA 75 MM BAR TO A LENGTH UP TO 6 MTR. PL.SUGGEST MCHINE DETAILS - THANKS- S.G.HEGDE
