Our Vertical Ring Forming Rolling Mills Machine is a high-performance forging equipment specially used in the bearing industry, such as the forging of bearing rings, ring gears, flanges, hubs, thin-walled cylindrical parts, etc. Through a unique structural design, it can roll and expand ring-shaped blanks to complete the manufacturing of various seamless ring-shaped forgings.

The working principle of this equipment is like a red iron block being slowly rolled into a large iron ring in a ring rolling machine. The equipment has built-in precision adjustment wheels, signal wheels and other accessories, and has a variety of adjustment functions. The size and shape of the iron ring can be precisely controlled by adjusting the feed speed and rolling ring angle.
Its wheel frame moving mechanism and inner baffle can significantly expand the size range of production parts, thereby improving equipment utilization and production quality, and equipment utilization is significantly improved.
In addition, our equipment adopts advanced control systems, such as self-developed CNC programs, which can realize fully automatic rolling, greatly improving the ring yield and rolling efficiency. In terms of data transmission speed, its network-style Ethernet communication data transmission speed can reach 100Mbps, ensuring efficient data transmission.

Our vertical ring forming rolling mill is a piece of equipment with excellent performance and strong practicality. It has been widely used in many countries and has been highly recognized by customers. Our Vertical Ring Forming Rolling Mills Machine has become an important equipment in the forging processing field of the bearing industry, and we look forward to providing high-quality forging solutions to more users.
