Thrufeed Centerless OD Grinding: Parameters and Troubleshooting .Apr 11, 2017 . In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right). Both wheels rotate in the same direction, but at much different speeds. The purpose of the grinding wheel is to remove material from the workpiece.centerless grinding process chart,Classification of grinding machines and their uses - nptelThe concept of single pass deep grinding at a table speed much higher than what is possible in a creep feed grinder has been technically realized in this machine.
