ATLANTIC :: Roll grinding

The roll grinding process is a special form of external cylindrical grinding between centres; the only difference being that the rolls being machined have much larger dimensions than conventional workpieces. The rolls are subjected to continuous wear in both hot and cold rolling mills and must be replaced and reworked at regular intervals.
