China’s Wuxi Paike New Materials Technology Co. placed an order with SMS group for what will allegedly be the world's largest ring-rolling machine for manufacturing aircraft engine components. According to SMS group, it is the first ring-rolling machine in the world capable of rolling jet engine rings with a maximum height of up to 1,500 mm (59 inches). This dimensional capacity will enable Wuxi Paike to efficiently manufacture the rings required for the next generations of jet engines. Commissioning of the new mill is expected in the fourth quarter of 2021. 

The ring-rolling machine has a radial rolling force of 1,000 tons and an axial force of 800 tons. SMS group will supply the machine fully equipped with electrical equipment, hydraulics, rolling tools and a software package. In addition to the main product, the machine is also designed to roll carbon-steel rings up to a diameter of 10 meters.

Based in Wuxi, Jiangsu Province, Wuxi Paike manufactures seamless rolled rings for aerospace applications. Forgings made by the company are also used in the chemical and ship-building industries.
