A ring generator wheel with improved coolant flow. The ring generator wheel of the present invention includes a shaft portion which is adapted for connection to an ophthalmic lens generating machine. A body portion is connected to the shaft and includes a first side adjacent the shaft portion and a second opposite side which has a wall member extending therefrom for forming a cup surface on the second side. The wall member has a radially inner surface, a radially outer surface and a peripheral edge, which peripheral edge includes a cutting surface for cutting of a lens. A deflection plate is provided having portions thereof extending generally radially and spaced from the second side for directing coolant media into the radially inner surface of the outer wall. The body portion includes surfaces for forming an aperture through the body portion from the first side to the second side for allowing coolant to pass therethrough. A shroud member is provided for containing a coolant on the second side. The coolant is directed at the shroud means and is contained and pumped through the aperture means to be distributed via the deflection plate to the radially inner wall for providing increased flow of coolant to the cutting surface.
