Ring rolling machine is a specialized piece of equipment used in the metalworking industry to produce seamless, high-quality metal rings. The process involves gradually deforming and reshaping the metal, resulting in a smooth, uniform ring with improved mechanical properties. Ring rolling machines are essential for manufacturing high-quality rings used in various industries, such as automotive, aerospace, oil & gas, and more

Ring rolling is a forming process for the production of rings. Commonly, a headed and pierced ring is used as a raw part to be expanded and possibly profiled with a ring rolling machine. Two or more rotating dies (rollers) are used for this purpose. The process can be performed on the material at high temperatures and also at ambient temperatures. The structure of the rings produced by ring rolling is perfectly homogeneous, and the process allows an optimal orientation of the metal fibers, adapted to the mechanical stresses to which the part will be subjected, thus giving it superior mechanical characteristics.

Ring rolling machines are used to produce seamless metal rings for various applications, including:

  • Flanges
  • Bearings
  • Gears
  • Wheels
  • Sleeves

Rings in the automobile, aerospace, oil & gas industry, etc.
Some common items produced by ring rolling include rings for machinery, aerospace applications, turbines, pipes, pressure vessels, roller and ball bearing races.

Types of Ring Rolling Machines
There are different types of ring rolling machines, such as vertical and horizontal machines, depending on the orientation of the machine and the ring being produced. Some popular manufacturers of ring rolling machines include Wuxi Daqiao Bearing Machinery Co., LTD, SMS Group, and Mossini.

Some advantages of ring rolling machines and the process include:

  • Short production time
  • Uniform quality
  • Close tolerances
  • Seamless rings with a homogeneous internal structure
  • Material savings, as the process does not produce excess material
  • Versatility in producing parts of various sizes, weights, and section geometry
  • Easy machining of the produced forgings

Ring rolling machines are essential tools in the metalworking industry, providing a versatile and efficient method for producing high-quality, seamless rings for various applications. With advancements in technology and the increasing demand for complex geometries, ring rolling machines continue to play a crucial role in the manufacturing process of numerous industries.
