Product Overview

Our D51Y vertical ring rolling machine combines reliability and durability with high precision and production capacity, offering excellent cost-effectiveness. Widely used for processing seamless ring parts including bearings, flat welding flanges, high diameter flanges, and small thin-walled barrel components, it is ideal for hot rolling and expansion processes of circular rough blanks.

Key Features

Good process compatibility: Capable of rolling various metal materials including high-temperature alloy steel, bearing steel, carbon steel, copper, and aluminum. Works efficiently with general forging equipment to replace traditional hole expanding processes.
Small size and light weight: Compact design allows flexible workshop layout without occupying excessive production space, ideal for small and medium-sized enterprises.
Excellent rigidity: Maintains stable operation under long-term, high-intensity conditions, preventing equipment deformation and ensuring consistent product quality.
Sensitive manipulation: Operators can quickly adjust parameters for precise control, meeting high-precision requirements.
