Applicable materials

High-temperature alloy steel, bearing steel, carbon steel, copper, aluminum alloy, etc.

Applications

Bearing manufacturing: Producing bearing races with high efficiency and precision.
Mechanical parts processing: Forming gear blanks, pipe flanges, and other ring-shaped components for automotive, machinery, and chemical piping industries.

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.

What is a vertical ring rolling machine, and how does it differ from a horizontal type?

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.

What is the maximum ring size your CNC ring rolling machines can handle?

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

How do I choose a CNC vertical ring rolling machine?

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.

What is the typical lead time?

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