Model 740 Large Acme Rolling
Ғылым және технология
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.

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.
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.
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.
Sick forces involved..
Outstanding video! Awesome machine!
What kind of Material are them Rollers made of?
yes please !!
Is the material growth calculated to achieve major diameter or are they full form rollers meaning the bar stock will lengthen only?
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
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.

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!
How to adjust thread line ? Used By server? Thank you!
Awesome!!
WOW !!
Similar to cold rolling/forming? What about the mechanical strengths, grain structure and geometrical accuracy?

its stronger than cut threads.
Only 340,000 lbs?! :p
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
wow
;) grande filettatrice--rullatrice tpi
