The Evolution of Nearnetshape Ringrolling Processes

The Evolution Of Nearnetshape Ringrolling Processes

by a ring roll mill in our company. Our ring roll mill was too small in both power and size to produce a large ring such as the fan case. The development of a near-net shape NNS, ring roll, technology was necessary to produce the ring with a complicated cross-sectional shape since machining from a plain shaped ring was too costly.
