Apr 15, 2015· 1. Introduction. A number of problems occur in the process of internal cylindrical grinding, which result from the process' kinematics. The most important impediment is the very long area of contact between the grinding wheel and the machined material, often caused by the minor difference between the grinding wheel and the ground opening's diameters.

Roll grinding is a special type of cylindrical traverse grinding operation in which the grinding wheel will be in contact with the work piece for a considerable amount of time with constant MRR which could result in rapid wheel wear and frequent dressing cycle. This will result in both increases in cycle time and decrease in productivity.

Cylindrical grind: For a cylindrical grind (spun ground), the reel is rotated as the grinding wheel is traversing. This is accomplished on a machine called a spin grinder. Spin grind creates a more accurate diameter control of the reel. A properly spun-ground reel should not need backlapping. Relief cylinder grind: For a cylinder grind with relief
