Features
  • Adopts a vertical structure. When the equipment rolls rings, the gravity direction of the ring is perpendicular to the rolling force direction, which helps to improve the stability and accuracy of the rolling process, reducing deformation and eccentricity of the ring during rolling.
  • Utilizes a CNC system to achieve precise control over the rolling process through CNC technology, including real-time monitoring and adjustment of parameters such as main roll speed, feed rate, and rolling force, ensuring the dimensional accuracy and quality stability of the rings.
  • Capable of achieving high-precision processing of ring dimensions, shape, and surface quality. Real-time monitoring and adjustment of various parameters during the rolling process ensure consistency and stability of product quality, reducing scrap rates.
  • High degree of automation, capable of continuous rolling production, reducing manual intervention and auxiliary time, greatly improving production efficiency.

Main Equipment

A vertical ring rolling machine feeds in the vertical direction, occupies less floor space, and automatically stabilizes the ring’s center of gravity—ideal for small- to medium-sized rings. Horizontal machines suit large-diameter, wide rings.

Standard vertical machines process rings from 55 mm to 1,300 mm in outer diameter. Custom sizes are available upon request.

Select based on forming needs: choose a standard vertical machine for radial-only forming; for combined radial and axial control, opt for a radial-axial model.

Standard models require 90–150 days. Custom configurations depend on specific requirements.
