Grinding of bearing rings

RING FACE GRINDING

During the operation, faces of the rings are machined to achieve desired surface parameters. This is done on double-disc grinders and the operation is often called parallel grinding. Technical characteristics of ANDRE wheels dedicated for the ring face grinding allow for high surface quality and high productivity of the grinding process.
