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.
