Ring and wheel rolling machinesForging - Pressing processes
SMS group has banked more than 80 years of experience in ring and wheel rolling. This dates back to Keller & Banning Maschinenfabrik und Eisengießerei (machine works and iron foundry) and Wagner Maschinenfabrik. Today, our ring and wheel-rolling activities stand for innovative technology, precision, and top quality. Almost 600 ring-rolling machines, over 100 complete plants and facilities, as well as satisfied customers all over the world conclusively prove our leading position. So you can rest assured: we know the industry inside out and meet your expectations.
Crucial to your products are the ring blanks. The better the starting product matches the final ring shape, the more cost-efficient your downstream processes are. This in turn means higher productivity. That's how you benefit from our reliable, future-proof ring blank presses with press forces of up to 100 MN.
Ultimate solutions - custom-made for you
Pressing forged ring blanks involves upsetting, pre-piercing, and piercing. There is also an extra step for profile blanks in the form of profiling. Sleeve-type rings are forged in a pot die. So, whatever the application and power range you want - we supply the right ring blank press for you.
Our ring rolling machines produce rings by enlarging the diameter of ring blanks. The process works like this: first, the blanks are heated to forging temperature. Then, our radial ring rolling machines reduce their wall thickness using a main roll and a mandrel. Alternatively, radial-axial ring rolling involves two axial rolls which simultaneously decrease the height of the blanks.
Here is another highlight from SMS group - our ring expanders which are perfect for ring rolling machines. The core components are a hydraulically movable expanding cone and expanding jaws. This is how you achieve excellent plastic deformation of rings. It's an extra advantage that the control system automatically accounts for the spring-back and compensates it during the next expanding stroke.
Included among today's most important and powerful technology systems for ring and wheel rolling is ROLLTECH - our software package that runs on standard PCs.
