Ring rolling machine 

Ring rolling machines are precisely adapted to meet the customer's requirements and rolls both profiled and rectangular rings with a high degree of precision as well as cost-effectively.The machine concept is particularly maintenance and user-friendly.
Ring rolling machines are suitable for producing rings for the following applications: Flanges, Bearings, Gears, Wheels, Sleeves, Rings in the automobile, aerospace, oil & gas industry etc.

Advantages:
1. High material utilization
2. Good quality
3. Good working conditions, high productivity
4. Low production costs

Ring rolling machine are divided into the radial rolling and radial-axial rolling(D53K series,CNC controlled). The radial rolling are divided into vertical type (D51 series) .
